Quick Guide – Piping
Pipework:
Pipework sizing should be based on the total equivalent lengths, which includes equivalent lengths for bends, traps, risers etc. A
guide to sizing is noted below:
Expansion Valves:
Suitably selected externally equalized expansion valves are required for each evaporator. Fitting of the valves should be carried
out as follows:
➢
Carefully braze the TEV outlet to the 1/2 ” evaporator inlet pipe approximately 100mm from the distributor. Protect both
the TEV and distributor from excessive heat using a wet cloth.
➢
Connect the liquid line to the 3/8” TEV inlet (preferably using a flare x solder adaptor). Ensure the correct size orifice is
fitted into the valve inlet before assembly and tightening.
➢
Make an equalization connection between the TEV and the suction line as per the TEV instructions.
➢
Fit the valve phial sensor to the suction line as per the TEV instructions once all brazing has been completed.
Solenoid Valve:
A suitably sized solenoid valve needs to be installed in the liquid line just before the TEV on single evaporator systems and just
before the ‘T’ piece in the main liquid line on Twin Systems (as shown on page 8). The liquid line solenoid valve is not supplied in
both Single and Twin system.

- The pipe sizes indicated in brackets are from the ' T ' piece to each evaporator.
- Pipework should be selected on the total equivalent length of run between all units.
