to air purge valve of sst 49 c061 001.
3. connect sst 49 c601005 to center joint of sst 49
c061001.
4. connect sst 49 c601 005 to vacuum pump.
5. connect sst 49 c061 004 to refrigerant
reservoir.
6. open all valves of sst 49 c061 001.
Attention
Close valve of manifold pressure gauge
immediately after vacuum pump stopped. Otherwise
the vacuum pump oil will flow back into the cooling
recirculation system and cause low efficiency of a/c.
7. start vacuum pump and keep it operating for 1
minute.
8. close center valve of the sst 49 c061 001.
9. open valve of the refrigerant reservoir.
Warning
When charging the system with refrigerant by using
service cans or refrigerant reservoir, running the
engine with the high-pressure side valve open is
dangerous. Pressure within the service cans or
refrigerant reservoir will increase and result in
explosion, the scattering metal fragments and liquid
refrigerant may cause serious injury. Therefore, do
not open high-pressure side valve with the engine
running.
10. start engine and operate the a/c compressor.
11. open low-pressure valve of sst 49 c061 001
12. refill refrigerant referring to refrigerant
charging inspection.
13. close low-pressure side valve of the sst 49 c06l
001 and valve of the refrigerant reservoir.
14. shut off engine and a/c compressor.
15. remove sst 49 c06l 006a, 49 c061007 from the
charging valves.
16. install caps on charging valves.
Pressure inspection of cooling system
1. install the ssts (charging device).
2. warm up the engine to normal operation
temperature and run it at a constant revolution
of 1,500 rpm.
3. set front fan switch at 4
th
position.
4. turn on a/c switch.
5. set to recirculate indoor mode.
6. set the temperature control to max cold.
7. set to vent mode.
