INSTALLATION

Page 2

A review of the following items beforeinstalling the Drain-All will help makethe right decision regarding optionswhich could be used to insure proper andlong-term maintenance free operation.

RUST AND SCALE

Even though Drain-All products aredesigned for handling these materials, itis recommended that the system is blowndown after all piping is installed for theDrain-All connections and before theDrain-All is connected to the piping. TheDrain-All, with a large, smooth, liquidflow path, easily handles contaminates inthe liquid once the system is in operation.If there is excessive rust and scale on acontinuous basis, use the Drain-All RustHandlerTM which can be installed on com-pressed air systems that have heavyamounts of rust and scale.

CONTROL AIR & BALANCE LINE

The control air line provides air throughthe sealed center tube to operate the aircylinder. Clean dry air should be used forthis control air supply. The balance lineprovides a means to handle the displacedair from the reservoir as the liquid entersthe reservoir. The control air line and thebalance line are two separate lines whichhave nothing in common with each otherand should never be connected to eachother in any way. Do not tie them togeth-er with a “T” fitting.

CONTROL AIR

On all models of the Drain-All, controlair pressure must be regulated withinspecifications provided in the InstallationGuide for each model. Never exceed 130PSIG on the control air connection to anyDrain-All. If the specified pressure forcontrol air is not available, contact yourdistributor for information on Drain-Alloptions to accommodate control air pres-sures.

BALANCE LINE

The balance line must have either (1)exactly the same pressure as the vesselbeing drained or (2) slightly less pressurethan the vessel being drained.

Exactly the same pressure is achievedwhen the balance line is tied back into thevessel being drained such as connectingthe balance line at a “T” fitting on thevessel’s pressure gage. A slightly lowerpressure is achieved by locating the bal-ance line connection on the air header acouple of feet downstream from the ves-sel being drained. When hooking the bal-ance line to an air header, there shouldnot be any other equipment connected tothe header between the balance line con-nection and the vessel being drained.

If there is absolutely no place to connectthe balance line into the air system, or ifa temporary installation is to be madewhile waiting for the next shutdown to tiein the balance line, the balance line canbe vented to atmosphere. Install the nee-dle valve which comes as a component ofInstallation Kit (not provided with highpressure models) into the opening on topof the Drain-All where ''Balance Line'' isindicated and follow the start up instruc-tions for adjusting the opening of the bal-ance line needle valve. There will bevery little air loss to atmosphere.

NO MANIFOLDS

There cannot be multiple system drainsthrough a manifold to one Drain-All.This will not work because all systemdrains will not be of the same pressure.Therefore, the liquid from the higherpressure drains will bypass the Drain-Alland flow backwards up the lower pres-sure drains. Installing check valves onsystem drains is not a solution to thisbecause pressure variations which inhibitproper operation will still be present.Proper installation of the balance line isnot possible with multiple drains hookedup through a manifold.

CORROSION

There are products and options availablewhich include corrosion resistant coat-ings and materials. If the applicationenvironment is highly corrosive, checkthese products and options to determineif they should be specified. Also availableare Drain-All models which handle high-er pressures and temperatures.

INSTALLATION STEPS

1. Prior to installing the Drain-All, blowdown the vessel being drained to removeexcessive rust, scale, and dirt knockedloose during piping installation.

2. Remove the Drain-All unit from thebox and set it in an upright positionwhere it will be connected. Most Drain-All, Inc. do not have to be secured.Larger volume and high pressure modelsmay require some form of movementrestraint. To insure proper operation in allinstallation layouts, the top of the Drain-All should be lower than bottom of thevessel being drained.

3. Using 1/2” pipe, connect the vesselbeing drained to the 1/2” liquid inlet onthe base of the Drain-All. Be sure toinstall a shut off valve and a bypass valvebetween the vessel being drained and theDrain-All to allow removal of the Drain-All "on the run" during any maintenance.After installing the piping, close the inletshut off valve.

4. Using 1/2” pipe, connect the Drain-All discharge outlet to a sealed drainpipeline or enclosed/covered trough. Theliquid discharged is under pressure andcan splash back if directed downwardtoward the bottom of a simple, shallow,open trough-type floor drain.

5. Connect a balance line from theDrain-All to the appropriate connectingpoint on the vessel being drained usingfittings and piping rated for the maxi-mum pressure rating of the system.Install an isolation shut off valve in thebalance line. After installing the balanceline close the balance line isolation shutoff valve.

6. Using the tubing and needle valveprovided in the installation kit, connectthe control air supply line to the controlair filter inlet on the Drain-All. Alwaysuse the cleanest and driest air possible toinsure long term maintenance free opera-tion. After installing the control air line,close the control air needle valve.

START-UP & TROUBLESHOOTING

Page 3

STARTUP

1. Close control air line and balance lineisolation valves as well as inlet isolationshut off valve.

2. Bring up system pressure.

3. Fully open control air needle valve.Check for leaks in control air line. Pushmanual test button on top of the Drain-All to verify air cylinder strokes properlyopening the discharge ball valve. Leavecontrol air needle valve open.

4a. Applications where the balance lineis connected back to vessel beingdrained. Fully open the balance line iso-lation valve. Check for air leaks on bal-ance line and fittings. Leave balance lineisolation valve fully opened.

4b. Applications where the balance lineis vented to atmosphere or connected to aheader pipe leaving the vessel beingdrained. Open the balance line isolationvalve only enough to ensure a smallamount of air can flow through it. Thiswill be adjusted in a later step.

5. Gradually open the inlet isolation shutoff valve to the full open position toallow liquid to enter the Drain-All. Thereservoir will fill until the float is raisedto the upper position actuating the con-trol circuit extending the air cylinder andopening the ball valve. Once the dis-charge starts, the liquid level in theDrain-All reservoir begins to lower. Thislowers the float back to its original posi-tion which deactivates the control circuitclosing the ball valve.

6a. Applications where the balance lineis vented to atmosphere or connected to aheader pipe leaving the vessel beingdrained. With liquid in the reservoir andthe liquid discharge ball valve in theclosed position, close the balance lineisolation valve. As you slightly open thebalance line isolation valve, look into thetranslucent sleeve just above the inletport and look for a trickle of small bub-bles. Continue to open the valve until you

see these bubbles indicating a proper set-ting for the balance line isolation valve.Remember, bubbles will only be seen ifthere is a pressure differential (when bal-ance line is vented to atmosphere or to aheader leaving the vessel being drained).

6b. When the balance line is connectedback to the vessel being drained there isno pressure differential between the inletand balance line and there will be no bub-bles in the liquid. In this applicationkeep the balance line isolation valve inthis connection fully open. The top of theDrain-All must be below the bottom ofthe vessel being drained.

7. Once properly installed, no furtheradjustments to the Drain-All are neces-sary. The Drain-All is fully automatic,discharging on demand as needed whenliquid accumulates.

TROUBLESHOOTING

1. Water does not enter Drain-All.

A. Balance line isolation shutoff valve isclosed which does not allow liquid toenter the Drain-All. Solution: Adjust balance line needlevalve per installation instructions.

B. Liquid inlet shut off valve is closed. Solution: Fully open liquid inlet shut offvalve.

C. Vessel drain, and/or pipe from vesseldrain to Drain-All inlet is plugged. Solution: Clear obstruction.

D. Location of balance line connectioncauses higher balance line pressure thanliquid inlet pressure. Unit is “back flow-ing”. Solution: Refer to installation instruc-tions for proper balance line installation.

2. Drain-All fills and will not drain.

A. Control air line needle valve is closed,or not fully open. Solution: Open control air needle valveto full open.B. Lack of adequate air pressure on con-trol air line.

Solution: Provide more than the mini-mum required PSIG to control air lineconnection per the product specification.If there is not enough control air pressureavailable, there are lower control airpressure options available - contact yourdistributor for details.

C. Hole in valve stem clogged. Solution: Clear obstruction. Do not alterhole diameter.

D. Filter element clogged or dirty. Solution: Replace part.

3. Discharge ball valve stays open.

A. Inner magnet installed upside down,i.e., north and south poles reversed.Solution: Reinstall inner magnet rotatingit 180 degrees, end for end.

B. Bleed for air cylinder clogged.Solution: Clear bleed hole on side of aircylinder located on opposite side fromcontrol air connection to the cylinder. Donot alter hole diameter.

C. Inner magnet stuck or not properlysealing against valve stem. This canresult from excessive oil and water con-taminates allowed to get into the controlair lines and then into the center tubethereby coating the inner magnet andcausing it to stick. Solution: Clean center tube and innermagnet and reassemble. Also, if possi-ble, connect the control air line to a cleandry air source which will prevent reoc-currence.

4. Excessive bubbling action in Drain-All.

A. Air leak in balance line and/or fittings. Solution: Refer to installation instruc-tions and start-up procedures.

B. Balance line isolation valve openedtoo far. Solution: Adjust balance line isolationvalve per installation instructions.

PRESSURE HANDLERTM - 750DIMENSIONAL PRINT

PRODUCT TECHNOLOGYHOW IT WORKS

Page 5

FIGURE 1: START OF CYCLE

The float (1) with a magnet molded in (2)is sitting on the base and is at the lowestlevel. The float magnet exerts a magneticforce repelling the center tube magnet (3)upward, holding it seated against an ori-fice in the lower end of the valve stem(4). This retains the control air coming inthrough the control air filter (5) in thecenter tube (6). The control air circuitincluding the center tube magnet andvalve stem are isolated from the liquidheld in the reservoir (7). The air cylinder(8) is in the home position and the dis-charge ball valve (9) is closed.

There is always a residual amount of liq-uid (10) left in the bottom of the reservoirafter each discharge cycle. The Drain-Allstops discharging before all accumulatedliquid is removed providing a liquid sealthat conserves expensive compressed air.Liquid (11) flows through the inlet port(12) and into the reservoir to start the fillcycle. Liquid continues to fill the reser-voir until the float has displaced enoughliquid to become buoyant and the floatpops upward to the upper position shownin Figure 2.

FIGURE 2: START OF DISCHARGE

The liquid flows in and raises the float toits highest position as shown. The floatmagnet is raised up past the center tubemagnet and repels the center tube magnetdownward opening the orifice in thevalve stem. This allows the control airheld in the center tube to flow through thecontrol air circuit to the actuating cylin-der. The actuating cylinder extends andopens the ball valve starting the dischargeof accumulated liquid.

When the correct amount of liquid hasbeen discharged, leaving a liquid seal inthe reservoir, the float has been loweredto a point where the float magnet is belowthe center tube magnet. In this position,the float magnet repels the center tubemagnet back upward against the valvestem orifice, which seals off the controlair flow to the actuating cylinder. Thecylinder has a spring which then returnsthe cylinder to its home position, closingthe discharge ball valve. The discharge isstopped as shown in Figure 1 and the fillcycle repeats.

THE BALANCE LINE PORT

The balance line port is a hole throughthe head of the Drain-All that goes intothe reservoir. This port allows the airtrapped in the top of the reservoir tomove out of the reservoir to allow liquidto enter the reservoir through the inletport. If there were no balance line port, asliquid entered the reservoir under pres-sure, the air trapped in the top of thereservoir would be compressed until itwas the same pressure as the liquid com-ing in and the unit would stop filling.

There are three methods of connecting tothe balance line port. The most effectiveis to connect it back to the vessel beingdrained as shown in the illustrationsabove. In this configuration, the reservoiris at the same pressure as the vessel beingdrained and the liquid is filling by gravi-ty. In this case, the top of the Drain-Allmust be lower than the bottom of the ves-sel being drained. The balance line canalso be attached to a header pipe leavingthe vessel being drained or vented toatmosphere using a needle valve. Ventingto atmosphere uses very little air if theneedle valve is adjusted properly.

Where should a Drain-All be installed?

At liquid accumulation points within asystem at compressors, air receiver tanks,intercoolers, aftercoolers, dryers, separa-tors, filters and drip legs.

Is this an oil-water separator?

No. Drain-All is a liquid drain and it willdrain oil, water, and particulates from thecompressed air system. Once this isaccomplished, the discharge should bepiped to an oil-water separator for finalprocessing.

Does this replace a dryer?

No. Drain-All works in conjunction witha dryer. Dryers typically convert watervapor in the compressed air into liquidwhich is usually discharged through asmall automatic drain device integral tothe dryer. These small automatic drainsare often prone to clogging and failure.When this occurs, such drains are nor-mally replaced with Drain-All unitswhich do not clog. A dryer prepares themoisture for removal from the system bycondensing it. It is the job of the reliableDrain-All to ensure that the liquid isactually discharged from the air system.

Is it mandatory to use a balance line?

Yes. The balance line provides a means tohandle the displaced air from the reser-voir as the liquid enters the reservoir.

What is the capacity?

In each application, based on pressuresand piping layout for that application, aDrain-All model will eject a specificamount of liquid on each cycle. Thisvaries by model and application.

What size compressor can it handle?

There are Drain-All models that willfunction effectively on any size compres-sor, compressed air system, atmospheric,or vacuum system. Provide your distrib-utor with specifications on the pressureand capacity of liquid you need to handleand an appropriately sized Drain-All canbe selected for your application.

Can one Drain-All be used to drainmultiple tanks and/or compressor sys-tems?

No. They will not all be of precisely thesame pressure level and the liquid wouldaccumulate in the lowest pressure drainor system thereby bypassing the Drain-All. Also, the use of check valves in mul-tiple drains to one Drain-All installationwill not make this work properly.Always install one Drain-All for eachitem of equipment to be drained.

Can a Drain-All be used in systemswith pressure greater than 170 PSIG?

Yes. Higher pressure models are avail-able. If the control air comes from higherpressure systems, a pressure regulator onthe control air line may be used and set atthe proper control air pressure or option-al control air components can be orderedto accommodate higher pressures.

Can the balance line and the controlair line be hooked together via a teeconnection?

No. Do not do this. Each of these airlines has its own specific purpose andshould never be tied together. The con-trol air should be the cleanest driest airavailable since it supplies air to the con-trol circuit to operate the pneumatic actu-ating cylinder which functions best andlasts longer if clean dry air is used.

The balance line allows the air in thereservoir to move out leaving room in thereservoir for the incoming liquid. This aircontains moisture that would be drawnacross a tee fitting tied to the control airline and be pulled directly into the con-trol air circuit, which can damage controlair pathways and the air cylinder.

Is there only one model Drain-All?

No. There are models for a wide range ofspecial applications. Dimensional alter-ations, design changes, componentoptions and special materials or coatingsare used in models to withstand high tem-peratures and highly corrosive environ-ments as well as accommodate high vol-ume discharge requirements.

What if the system has an abundanceof metallic trash?

Before installing the Drain-All, blowdown the system being drained to elimi-nate as much existing loose scale as pos-sible. The large, smoothly contoured flowpaths in Drain-All units handle normallevels of debris found in most applica-tions. Should there be an excessiveamount of debris such as heavy rust, askyour distributor about Drain-All’s RustHandlerTM Model designed for that kindof severe duty.

How can the Drain-All be used as aninstrument to gather data on conden-sation in a compressed air system?

With the use of Drain-All’s optionalcycle counter, the Drain-All can provideaccurate data on the amount of liquid thata compressed air system generates. Thisis very useful when buying new com-pressed air system equipment because aDrain-All with a cycle counter is abenchmarking instrument. Since theDrain-All discharges the same amount ofliquid on every cycle, knowing the num-ber of cycles over a specific period oftime under specific temperature andhumidity conditions provides the abilityto track liquid production. This bench-marking can be correlated to ongoingchanges in ambient temperature andhumidity conditions to identify variancesin liquid production indicating changeswhich need investigation. Too few cycleswould mean not enough liquid is reach-ing the Drain-All and should be investi-gated. Too many cycles would mean toomuch liquid is being made or too muchliquid from somewhere is reaching theDrain-All and should be investigated.Knowing the amount of liquid a systemproduces is also essential for properlysizing oil-water separators.

FREQUENTLY ASKED QUESTIONS

Page 8041502 PH 750 IG

CLOGGED DRAINSOther drain devices with small orificesand poppet style valves are prone to clogwhen solid debris is present. Each Drain-All has a large, smooth liquid flow pathand discharge port as well as a heavyduty shear action ball valve designed toalleviate this problem.

ELECTRICITYTimer valves require electricity. There isa cost for installing and maintaining theelectric outlets they require as well anongoing operating cost of electricity yearafter year. Drain-All requires no electric-ity to operate since it is totally pneumaticand can be easily installed at any pointalong the compressed air system provid-ing low cost installation and ongoingoperation.

RELIABILITYDrain-All’s cycling is controlled by apatented magnetic interaction with atotally pneumatic control circuit. Whileother pneumatic drains have a complexlever action “toilet bowl” type internalfloat with many parts, there are few mov-ing parts in the Drain-All. Since theDrain-All is totally pneumatic, it is notaffected by power outages or the othervulnerabilities of electrical devices suchas timer solenoid valves, motorized ballvalves or electrically operated float traps.

BYPASSED DRAINSSmaller drains become plugged so oftenthat cleaning them out becomes a verylabor intensive operation. To avoid con-stant cleaning, there is a temptation tobypass the inadequate drain and crackopen a manual bypass valve causing it todrain constantly thus causing a constantflow of wasted compressed air. Drain-All’s anti-clog design eliminates thetemptation to bypass the drain.

SYSTEM BLOW DOWNManually operated drains, timer solenoidvalves, motorized ball valves or electri-cally operated float traps blow away largequantities of expensive compressed air.Manually operated drains waste consid-

erable compressed air because most oper-ators feel it is necessary to have the drainopen an extended period of time in orderto get all the liquid out. Timer valves arealmost always set to be open longer thannecessary in order to get all of the liquidout and this also passes large quantities ofcompressed air down the drain. Drain-All avoids this waste of compressed airand the resulting pressure drop in thecompressed air system by maintaining aliquid seal in the bottom of the Drain-All’s reservoir between each cycle.

AMOUNT OF LIQUIDManual draining and timer valve drainingdo not provide any information on thequantity of liquid being produced in thecompressed air system.

Each Drain-All model discharges a spe-cific amount of liquid on each cycle in agiven application. With the addition of aDrain-All cycle counter on the Drain-Allunit, it is easy to track how much liquid isproduced over any period of time. This isparticularly important for benchmarkingsystem equipment performance and per-forming trend analysis. For example, it isessential to know the quantity of liquidproduced by a compressed air system toproperly size oil-water separators.

The counter coupled with a Drain-Allunit is an instrument. Once installed, itprovides tracking of the number of cyclesfor periods of time at different ambienttemperature and humidity conditions.This data can be plotted on a chart.During operations thereafter, a check onthe number of cycles per time period ofactual operation compared to the chartfor a given temperature and humidity willshow if the correct amount of liquid isbeing received by the Drain-All. Toomany cycles compared to the chart indi-cates excessive liquid is being producedsomehow and should be investigated.Too few cycles indicates that not enoughliquid is being produced and this tooshould be investigated.

OVER-DRAININGManual drain valve operation and timervalves are usually set for overkill in fre-quency and duration of drainage times inorder to be certain that no liquid accumu-lates in the system. This results in wasteof expensive compressed air. Drain-All isdemand activated and drains only whenthe liquid reaches the predetermined trig-ger point. The Drain-All does not over-drain or blow down the system.

UNDER-DRAININGTimer drains must be preset to establishthe frequency and duration of drainage.The settings are vastly different in peri-ods of high humidity from what theywould be in periods of low humidity. It iscommon for this adjustment to be over-looked in the transition from winter tosummer. Therefore, the settings are inad-equate to handle the high summer quanti-ties of liquid which results in excess liq-uid accumulation in the compressed airsystem. This liquid often backs up andcan cause damage to dryers, compressorsand hand tools that is expensive to repair.The Drain-All is designed to cycle asneeded when liquid accumulates andrequires no adjustments from season toseason.

LIQUID REMOVALThe air pressure in the system beingdrained forces the liquid out of the Drain-All reservoir. Because the power of theair system is behind it, the discharge canbe directed upward, to a containmentvessel, oil-water separator or an overheaddischarge piping system.

In the drawing below, there is a dotted lineindicating the level of the trigger level of thetrap. This is the height the condensate mustreach in the trap to start the discharge cycle.

When the balance line port is connectedback to the vessel or header pipe, asshown in the drawing above, the trap isfilling by gravity. In these applications thebottom of the vessel must be higher thanthe top of the trap so that the condensateflows by gravity down and out of the ves-sel into the trap.

When the bottom of a vessel beingdrained is lower than the trigger point inthe trap, as shown in the drawing to theright, do not connect the balance line portto the vessel or header pipe.

In the drawing to the right, if the balanceline were connected to the vessel or head-er pipe, the condensate would be filling

the trap by gravity. With the bottom of thevessel being lower than the top of the trap,this would result in condensate backing up inthe vessel to the same height of the conden-sate in the trap. When the condensate reached

the trigger level in the trap, shown by the dot-ted line, the condensate would also reach thesame height in the vessel (the same dottedline).

In an application where the bottom of thevessel is lower than the top of the trap, thebalance line must be vented to atmos-phere. Venting a small amount of air fromthe trap reservoir to atmosphere results ina pressure differential in the trap reser-voir. This allows the pressure in the ves-sel to push the condensate downward, outof the vessel, and up into the trap. Thisachieves proper filling of the trap whileremoving all condensate from the vessel.Send application questions to:

INSTALLATION LOCATIONS

Method -1Connect the balance line port to the vesselproducing the condensate. This is the pref-ered method since it is a closed-loop arrange-ment. In the first four applications above, thebalance line is connected back to the vesselthat is producing the condensate. The pres-sure on the incoming condensate to the trapand the pressure in the balance line are thesame and the trap is filling by gravity. For thismethod, the top of the trap must be below thebottom of the vessel being drained.

Method -2Connect the balance line port to the head-er pipe leaving the vessel producing thecondensate. This is an alternate method toMethod-1 when there is no convenient loca-tion to connect the balance line to the vessel.This is shown above in the drip leg applica-tion. In the case of a dryer, however, connect-ing the balance line to the header pipe leavingthe dryer essentially results in a bypass of thedryer function. The condensate from thedryer would have a path up the balance lineand back into the flow of dry air leaving thedryer. That would not be desirable.

Method -3Vent the balance line port to atmosphereusing a needle valve inserted in the balanceline port and slightly opened. This can beused on any application but must be usedwhen the bottom of the vessel is lower thanthe top of the trap. The needle valve shouldbe opened slightly to a point where only asmall amount of air can be felt leaving theneedle valve. This method provides a pres-sure differential in the trap reservoir and con-densate is blown into the reservoir instead offilling by gravity.

VESSELS WITH BOTTOM LOWER THAN THE TRAP’S TRIGGER LEVEL

THERE ARE THREE METHODS USED TO CONNECT THE BALANCE LINE PORT

1. Connect balance line to vessel being drained, to header leaving vesssel being drained, or vent to atmposphere - do not manifold balance lines together.

3. Bring control air from clean dry source downstream of dryer if possible, can manifold control air lines together.2. Balance line balances reservoir of trap to vessel being drained. Control air operates air cyclinder. These two should not be connected together.

Control air from clean dry airsource if at all possible
