Efficiency by transferring

heat within the building


On receipt of signals received from the individual indoor units, a modulating valve within the relevant multi controller controls the flow of refrigerant to the indoor unit

. . . . . each circuit of the multi controller has a dedicated modulating valve . . . . .


. . . . . and in conjunction with a variable speed compressor in the outdoor unit . . . . . . .

What are the ‘rules’

for installation?

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

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 adequatelysupported and joints not understress

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 anyleaks, pressurise pipework to 30bar with OFN

Leave this pressure in the system for at leastfour hours, recording the pressure and ambienttemperature at the start of the test

After at least four hours check and record the pressure and ambient temperature and note any pressure loss.

Following the detection and repair of anyleaks evacuate system to remove any remainingmoisture

After at least two hours evacuation (depending on ambient conditions) start addingthe 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

Installation rules

23% R32

25% R125

52% R134a

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
