What are the ‘rules’ for installation?

Installation rules All pipes must be of refrigeration quality, hard-drawn or soft copper All copper used must be new and previously unused Pipes must be cut using a pipe cutter – not a hacksaw!

Installation rules All cut pipe lengths must be capped after use If in doubt over pipe quality – don’t use it!

Installation rules All pipework must be adequately supported and joints not under stress Oxygen-free nitrogen MUST be passed through pipework during brazing All interconnecting pipework should be tested to 10bar using OFN and tested for leaks

Installation rules Following the detection and repair of any leaks, pressurise pipework to 30bar with OFN Leave this pressure in the system for at least four hours, recording the pressure and ambient temperature at the start of the test After at least four hours check and record the pressure and ambient temperature and note any pressure loss.

Installation rules Following the detection and repair of any leaks evacuate system to remove any remaining moisture After at least two hours evacuation (depending on ambient conditions) start adding the additional refrigerant require for the system Ensure that the refrigerant (R407C ONLY) is charge into the system in its liquid phase – into the liquid line

Installation rules Once the system pressure has equalised open the unit’s service valves and operate the unit to draw in the remaining charge through the unit’s suction valve. REMEMBER – the refrigerant must be weighed into the system and MUST be R.407C

Why must refrigerant R407C be charged as a liquid? If charged as vapour only the high pressure refrigerant at the top of the cylinder will be drawn into the system
