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 . . . . .

a variable speed compressor

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?
23% R32
25% R125
52% R134a
If charged as vapour only the high pressure refrigerant at
the top of the cylinder will be drawn into the system
