Super Multi INTELLIGENCE
The performance of a Super Multi in a smaller,
quieter, more sophisticated unit
It might look like a Modular Multi but dont try
connecting it to another SMi unit!

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 . . . . .

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 dont use it!
26

Installation rules
All pipework must be adequately supported 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
27

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.
28

Installation rules
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
29

Installation rules
Once the system pressure has equalised open the
units service valves and operate the unit to
draw in the remaining charge through the units
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?
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
