4.3.2 STOP VALVE INSTRUCTION
In general, the shape of stop valve and names of each part are
shown in Fig.4-5.
Eect of stop valve:
- Stop the system when the unit is working.
- When water tank connects with the master unit, vacuumize and
add refrigerant through it.
- Stop the system and then recycle refrigerant to master unit when
maintaining.
Open and close the stop valve:
- Open: dismantle the bonnet by wrench and insert an allen key
to spool, open the stop block anticlockwise and then tighten the
bonnet.
- Close: use a wrench to dismantle the bonnet and insert an allen
key to spool, close the stop block clockwise and then tighten the
bonnet.
4.4 VACUUM DRYING
4.4.1 PURPOSE
Vacuum drying should be performed in order to remove moisture
and non-condensible gases from the system. Removing moisture
prevents ice formation and oxidization of copper piping or other
internal components. The presence of ice particles in the system
would cause abnormal operation, whilst particles of oxidized copper
can cause compressor damage. The presence of non-condensible
gases in the system would lead to pressure fluctuations and poor
heat exchange performance.

ITEM DESCRIPTION IMAGE NOTE
1
Connect the blue (low pressure side)
hose of a pressure gauge to the outdoor
unit gas pipe stop valve.
Before performing vacuum drying, make sure that all
the outdoor unit stop valves are firmly closed.
2Connect the yellow hose to the vacuum
pump.
1. Mixing of pump lubricant with compressor oil could
cause compressor malfunction and a one-way valve
should therefore be used to prevent vacuum pump
lubricant seeping into the piping system.
2. Using a vacuum pump with a discharge in excess of
4L/s and a precision level of 0.02mmHg is
recommended
3Connect the outdoor unit gas pipe stop
valve to water tank gas pipe
4Connect the outdoor unit liquid pipe
stop valve to water tank liquid pipe
5
Start the vacuum pump and then open
the pressure gauge valves to start
vacuum the system.
6After 15-20 minutes, close the pressure
gauge valves.
7
After a further 5 to 10 minutes check
the pressure gauge. If the gauge has
returned to zero, check for leakages in
the refrigerant piping. If the gauge is no
change, then vacuum drying is OK.
8
Re-open the pressure gauge valves and
continue vacuum drying for at least 20
minutes and until a pressure dier-
ence of 756mmHg or more has been
achieved. Once the pressure dierence
of at least 756mmHg has been achieved,
continue vacuum drying for 20 minutes.
9Close the pressure gauge valves and
then stop the vacuum pump.
10
After 1 hour, check the pressure gauge.
If the pressure in the piping has not
increased, the procedure is finished. If
the pressure has increased, check for
leakages.
After vacuum drying, keep the blue and red hoses con-
nected to the pressure gauge and to the outdoor unit
stop valves, in preparation for refrigerant charging
Table 4-5
4.5 REFRIGERANT CHARGE
Pipe length is 2~20m.
If the pipe length is less than 10m, there is no need to add additional refrigerant charge.
If the pipe length is more than 10m, adding additional refrigerant charge is necessary, and the rule is 20g/m for the additional pipe.
