Carefully cut the security straps on the lid/s of thetank.Remove the kit inside the tank and take thecontents from the plastic bag.
Spread the contents out in front of you and ensureyou have all the contents to proceed and thereis nothing missing.
Fit the screwed breather assembly.
Add the insulation jacket that was provided withthe tank kit, wrapping the larger section all theway round the tank.
Familiarise yourself with the individual items andthe fitting instructions overall. Read carefully.Understanding the instructions is your bestprotection from costly mistakes.
Having transferred the tank into the roof space withall the holes drilled, first put in and fasten the 22mmcompression tank connector with the rubber washerinternally and the plastic washer externally andassemble outlet pipe.
Fit the screwed vent pipe sleeve for theexpansion pipe.
Fasten the insulation using the ribbon provided.Use the smaller insulation piece provided asinsulation for the top of the tank.
Offer up and mark holes for the breather and vent using asharp 27mm hole saw, drill the holes for the breather and thevent. All the drilling and marking of the holes can be doneat a lower level than the roof space. Once drilled, the tankcan be passed up through the loft opening prior to the fittingof any of the kit.
Now connect the 22mm warning pipe to thescreened warning pipe elbow ensuring warningpipe accommodates incoming supply.Fit restrictor to inlet if neccessary.

Take your ball valve attach the 41/2" float andassemble into the tank.
9Pass the brass connector through and attach theball valve back plate to the outside face of the tank.This back plate is designed to spread the load ofthe continually moving ball valve as the tank emptiesand fills. Assemble service valve onto ball valve.Adjust float position to suit waterline in tank.
Add the screw and tighten the ball valve fitting.Hand tighten and then tighten with spanner 1/2a turn. Do not over tighten.

Mark the first of a series of holes. First the ball valve this holeis situated 60mm (+/- 5mm) from the top of the tank. Markthe hole to be drilled with a light marker or crayon. Do not useany scribe or sharp instrument whatsoever. Make a mark forthe warning pipe hole - this should be 90mm (+/- 5mm) fromthe top using a sharp 22mm hole saw, drill the hole for theball valve and 27mm hole saw for the warning pipe.
Turn on the cold water supply (stop cock usuallyunder the kitchen sink) and then turn the servicevalve using a screw driver, to the on position (in linewith water flow).
The above illustrations show a normaltank installation. Circumstances andaccess can change the approach butwe hope the above extensiveprocedure, in pictures, gives anyoneinstalling a tank the ability to deal evenwith the most difficult circumstancesand still do the job right.
WE APOLOGISE, IN ADVANCE, TO ANYPROFESSIONAL PLUMBER ORINSTALLER WHO REGULARLYINSTALLS OUR TANKS. WEAPPRECIATE THAT YOU DO NOT NEEDTHIS LEVEL OF FITTING INSTRUCTION.
Attach the cold water pipe (inlet) to the service valveconnection and tighten ensuring fittings are heldfirm while tightening. DO NOT OVER TIGHTEN.
Turn the tank round and mark the hole for the outletpipe. This hole should be 50mm from the baseand again marked with a marker or light crayonnot a scribe or sharp instrument.
Now assemble the screened elbow filter/meshwarning pipe into the other hole. This warning pipeaccepts any 22mm overflow pipe including copperthen push fit the dip tube internally into the elbow.

As the tank fills, check all round for leaks bothwith eye and hand. Clip down the lid/s.

IMPORTANTBefore positioning tank ensure it is supported on a solid suitable baseover the whole area of the tank, ensuring correct load over joints toaccommodate weight when full.
Drill using a 29mm diameter hole saw. This isthe hole for the 22mm compression tank connectorthat will be the outlet. As stated above drill thehole for the outlet pipe at the opposite end to theball valve. This means the inlet and outlet createa circulatory flow of water inside the tank.
