Application data Unit selectionSelect equipment to match or be slightly less than anticipated peak load. This provides betterhumidity control, fewer unit cycles, and less part-load operation.For units used in spaces with high sensible loads,base equipment selection on unit sensible load,not on total anticipated load. Adjust foranticipated room wet bulb temperature to avoidunder sizing equipment.When selecting equipment that has outdoor airintroduced into the unit, determine the mixconditions of room air and outdoor air at designconditions. The cooling capacity tables in thisliterature are based on 80 F edb. To select the proper equipment, adjust for actual dry-bulb andwet-bulb conditions with the required outdoorair.

Unit mounting Unit leveling — For reliable operation, unitsshould be level in all planes.Clearance — Provide adequate clearance forairflow. See dimensional drawings for proper clearances. The condensing units are designedfor free-blow application. Air inlets and outletsshould not be restricted. Outdoor fan externalstatic pressure available is less than 0.1 in. wg.Unit location —Units may be wall mounted, padmounted at ground level, roof mounted, or mounted on or under a deck or patio. Be surethat water from roof does not drain directly ontothe unit. If 38 Series condensing units aremounted near a wall, the condenser air shoulddischarge away from the wall. This will provideinherent coil protection and the best possiblesound and airflow performance.Winter start — The use of a winter start controlmay extend the operation range (generally to 35F or 40 F). Winter start bypasses the low-pressure switch for 3 minutes.Crankcase heater — Units with low ambientcontrol should be equipped with crankcaseheaters to prevent refrigerant migration duringcompressor off cycle.

Refrigerant lines General refrigerant line sizing: 1. All charges, line sizing, and capacities are based on runs of 25 ft. For runs over 25 ft, consult the appendix A. NOTE: The minimum line length should be 10 ft.

Unit operation NOTE: AUTO fan mode is used as the unit operation example for ALL fan coil units in this section. Contact your local Carrier dealer for operation information in other fan modes. Fan coil units — Duct free fan coil units have a self-contained control system that determines the set point for fan coil operation, fan mode operation, and heating mode operation (if provided). The un-ducted fan coil and ducted fan coil units are equipped with a thermostat. For ducted fan coils the field installed thermostat determines the set point for fan mode operation, and electric heat operation (if provided). On a call for cooling operation by a single fan coil unit, a signal is sent to the 38H outdoor unit and energizes a control relay.

*For tubing line sets between 50 and 175 ft, refer to Residential Split-System Long-Line Application Guideline.†Only when low-pressure switch is used.‡Required for Low-Ambient Controller (full modulation feature) and MotorMaster™ control only.** Required on Heat Pumps only.

This Long-Line Application Guideline appliesto all Carrier residential air conditioner andheat pump split systems that have a nominalcapacity of 18,000 to 60,000 Btuh. Thisguideline provides required system changesand accessories necessary for any residentialproduct having piping requirements greaterthan 50 ft or installations where indoor unit is located above outdoor unit.This guideline is intended to cover applicationsoutside the standard Installation Instructions.This guideline is for standard, single-speedproducts. For applications involving 2-speedproducts, refer to Step 6 first.NOTE: The presale literature for outdoor unitmust be referred to in conjunction with thisguideline.

Step 1—Approved SystemsAny residential indoor/outdoor unitcombination listed in the outdoor unit presaleliterature is an approved system, EXCEPT thefollowing:• Indoor coils with capillary-metering devices• All equipment less than nominal 18,000 Btuh

• All 1/4-in. and 3/16–in. liquid-lineapplications• Any indoor furnace coil/fan coil not listed inoutdoor unit presale literature• Any application which has interconnectingtubing with an equivalent length greater than175 ft

Step 2—Interconnecting Tubing SizingTable 2 lists recommended interconnectingvapor-line diameters for equivalent total-linelengths. All residential split systems installedin long-line applications must use only 3/8-in.liquid lines. Equivalent line length equals thelinear length (measured) of interconnectingvapor tubing plus losses due to elbows. (SeeTable 3 and Fig. 3.) Liquid lines larger than3/8-in. OD greatly increase charge quantity ofthe system. Excessive charge increases risk of migration and compressor damage. Table 2 provides the estimated percentage of nominalcooling-capacity losses based on the standard,required vapor line size versus what is selectedfor the long-line application. Since the vaporline is the discharge line in heating mode,losses are minimal.

38H

K/H

Q

Calculate the linear length of vapor tuberequired, adding any losses for the totalnumber of elbows for application. (See Table6.) Using this equivalent length, select desiredvapor-line size from Table 2. Subtract thenominal percentage loss from outdoor-unitpresale-literature Detailed Cooling Capacitiesdata for the given indoor/outdoor combination.Reference all notes of Table 2.NOTE: When specifying vapor-lineinsulation, be aware of the following standardpractice:All standard accessory-tubing kits are suppliedwith 3/8-in. insulation on vapor line.For minimal capacity loss in long-lineapplication, 1/2-in. insulation should be specified.For reference only, the close cell insulationmaterial specified for accessory tubing kits is acompound of vinyl, neoprene, or nitrile blendsof these polymers. Performance requirementsinclude thermal range of 0° F to 200°F (-17.8°C to 93° C) and a maximum thermalconductivity of 0.28.NOTE: Special consideration must be given toisolating interconnecting tubing from buildingstructure. Isolate tubing so that vibration ornoise is not transmitted into structure.

Step 3—Metering Device Sizing The metering device for a long-line applicationmust be flexible enough to compensate forfrictional losses due to long refrigerant linesand installed system design (indoor coil aboveor below outdoor unit.) The piston or TXVprovides such flexibility.The piston should be changed for both indoorcoil and outdoor heat pump unit, depending onsystem configuration and line length. Tables 4 and 5 provide necessary changes for a givenapplication.Use Tables 4 and 5 when selecting correctpiston size. Outdoor unit presale literaturemust be consulted to determine meteringdevices specified for standard applications.After determining standard application pistonsize(s), refer to Tables 4 and 5 as they relate to system design (outdoor unit above or belowindoor unit) per equivalent length of tubing.NOTE: If total equivalent horizontal length is100 ft or longer, both indoor and outdoorpistons must be increased 1 full piston size, in addition to changes required by Tables 4 and 5.After finding appropriate change in pistonsize, add or subtract the change from original piston number. If piston size is decreased,round new piston number down to nearestcommon piston number found in Table 6. Ifpiston size is increased, round new piston

number up to nearest common piston numberfound in Table 6.

EXAMPLE:An 042 size heat pump is 75 ft above an 042 sizefan coil. The 042 size heat-pump presale literaturespecifies a size 80 indoor piston and size 63 outdoorpiston. To establish correct indoor piston size for a75 ft vertical separation, refer to Table 4. For a 75 ft equivalent line length, the piston change is -5.Therefore subtract 5 from the original indoor piston size of 80: 80 – 5 = 75 Table 6 provides common piston sizes. In thisinstance, 75 is not listed, therefore round DOWN to next piston size, which would be 74. To establishcorrect outdoor piston size for a 75 ft verticalseparation, refer to Table 5. For a 75 ft equivalentline length, the piston change is +4. Therefore add 4 to the original outdoor piston size of 63: 63 + 4 = 67Since 67 is listed in Table 6, that is the piston whichshould be used. If a 67 size piston were not listed, itwould be necessary to round UP to next piston size.

Step 4—Liquid-Line Solenoid AndTubing ConfigurationThere are 2 types of liquid-line solenoids: 1 forsingle-flow applications and the other for bi-flow applications. The purpose of having 2 solenoids is to minimize the valve internal-pressure drop in accordance with refrigerant flow direction and liquid migration to the compressor. The bi-flow solenoid is designedto have minimal refrigerant-pressure drop ineither flow direction, which makes it suitablefor heat pump usage. Refer to Table 7 forliquid-line solenoid kit part numbers.NOTE: When installing a liquid-line solenoid,the system may require a minimum 60-va low-voltage transformer.Each type of solenoid has an indicator flowarrow stamped on the valve body. Whensolenoid is closed (not energized) and pressureis applied in direction of flow arrow, completeshutoff occurs. If pressure is applied againstdirection of flow arrow, leakage through valveoccurs. When determining proper installationof valve within liquid line, 2 considerationsmust be made:1. Direction of flow arrow2. Where solenoid is installed in system.TXVs can only be substituted for liquid-linesolenoids in singleflow air conditioningsystems. Bi-flow TXVs allow liquid migrationto coldest point during off cycles, which couldallow liquid into compressor. Fig. 2 through 5detail proper installation of liquid-line solenoidand provide applications where TXVs may besubstituted. Reference all notes of the appropriate figures.

24

Step 5—Charging InformationWeigh in appropriate refrigerant charge, thenuse the standard practices of superheat-charging method for piston applications and subcooling-charging method for TXVapplications to confirm correct charge. Thestandard charging methods can be found onoutdoor unit-information plate, in unitInstallation Instructions, or in the ServiceManual. Since total system charge is increasedfor long-line applications, it may be necessaryto calculate the additional refrigerant charge.Since long-line applications only involve 3/8-in. liquid lines, the additional refrigerantcharge required is 0.6 oz of Refrigerant 22 (R-22) per ft of 3/8-in. liquid line over 15 ft.

EXAMPLE:To calculate additional charge required for a 25–ftline set: 25 ft – 15 ft= 10 ft X 0.6 oz/ft = 6 oz of additional charge

The rating-plate charge of a given outdoor unitis for a standard application of 15 ft of interconnecting tubing. The rating-plate chargecan be found on outdoor unit-rating plate or inoutdoor unit-presale literature. Long-lineapplications do not require additional oilcharge. 38
