5.6.7 INSULATING THE REFRIGERANT SHUT-OFF VALVE
Insulate the refrigerant pipes, including the shut-off valve, following
connection to the external unit.
▶ Trim insulation material [3] so that it fits snug around the refrigerant
valves.
▶ Install the insulation [3] for the liquid refrigerant pipes (small,
2 holes) on the liquid side so that the holes fit the valve caps [1] and
cover the shut-off valve [2] entirely.
▶ Trim the insulating material for the liquid refrigerant pipe work and
make 2 holes for the locking caps.
▶ Fix to the pipe so that the holes surround the locking caps [1] and the
shut-off valve [2] is completely covered.

▶ Secure insulating material [1] with cable ties.
▶ Trim off the excess “tails” of the cable ties [2].

▶ Trim off the excess “tails” of the cable ties [2].
5.6.8 EVACUATING AND DRYING THE REFRIGERANT CIRCUIT
Remove air from the refrigerant circuit by following recommended
procedure for vacuum drying. In the case of inadequate vacuum drying
air and water vapours remain in the refrigerant circuit. These may result
in an abnormal rise in positive pressure or in a drop in negative pressure
as well as to a loss of quality in the refrigerant oil through moisture. This
may have a negative effect on the compressor service life.
VACUUM DRYING
▶ Connect a high performance vacuum pump to the Schrader valve
( Fig. 32, [3]).
▶ With the vacuum pump build a pressure of 101 kPa(g) (5 Torr).
▶ Maintain this pressure for at least 1 hour.
– During this time check the vacuum pressure constantly at the
pressure gauge.
– If there is any moisture left in the pipe, complete evacuation is
sometimes not reached if the vacuum pump is applied for only a
short period.
▶ Close the distributor valve and then switch off the vacuum pump.
▶ Observe the pressure for one minute.
Should the pressure rise during that time (vacuum reduces), evacuate
and repeat the final test.
▶ Separate the vacuum pump from the refrigerant circuit.

WARNING: Personal injury from rupturing refrigerant
pipes!
Air bubbles trapped in lines can result in pressure peaks
which can result in pipes bursting.
▶ Never allow air to remain in the lines.
The refrigerant circuit is pre-charged with 2.5 kg of
R410A refrigerant. Commissioning does not require
topping up with refrigerant.
Never use the refrigerant from the external unit to purge
air from the refrigerant lines.
