- BE SURE TO USE REFRIGERANT RECLAIMING EQUIPMENT
WHILE DISCHARGING THE REFRIGERANT.
- Purge the air from charge set’s centre hose.
- Be sure to check for gas leakage.
Caution
If gauge needle does not move from 0
cmHg (0 MPA) to -76 cmHg (0.1 MPa) in
step (3) above, take the following
measures:
If the leaks stop when the piping
connections are tightened further,
continue working from step 3.
If the leaks do not stop when the
connections are retightened, repair the
location of the leak.
7. Tighten the service port caps of both the 3-way valves at a torque
of 18 N.m with a torque wrench.
8. Remove the valve caps of both the 3-way valves. Position both of
the valves to “open” using a hexagonal wrench (4 mm).
9. Mount the valve caps onto the 3-way valves.
11.4. Balance refrigerant of the 3-way valves
(Lack of refrigerant in the refrigeration cycle)
