heat within the building

13. Super Multi INTELLIGENCE
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

14. Super Multi INTELLIGENCE
and in conjunction with a variable speed compressor in the outdoor unit

Inverter compressor starts at 4%
if demand is still
greater than 50% inverter slows to
4% capacity and
and if demand is 50% or
greater runs up to full speed (or less if demand is >50%)

16. Super Multi INTELLIGENCE
the required amount of refrigerant is delivered to each indoor unit to match demand.

17. Super Multi INTELLIGENCE
Using one multi controller
up to four indoor units may be installed

18. Super Multi INTELLIGENCE

23. What are the ‘rules’
for installation?

24. 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!

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

26. 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

27. 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.

28. 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

29. 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

30. 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
