Service warnings
U-3
Warning
When charging cooling system with refrigerant by
using service cans or refrigerant reservoir, running
the engine with 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 the high-pressure side valve with the
engine running.
18. open low-pressure side valve of the sst 49 c061
001 and charge with refrigerant until the
weight of refrigerant reservoir has decreased by
400g (14.1 oz) from the mass in step 13.
19. close low-pressure side valve of sst 49 c061
001.

20. start engine and operate the a/c compressor.
21. open the low-pressure side valve of sst 49 c061
001 and charge with refrigerant until the
weight of refrigerant reservoir has decreased by
650g (22.9 oz) from the mass in step 13.
22. close low-pressure side valve of the sst 49 c06l
00l and the valve of the refrigerant reservoir.
23. stop engine, turn off a/c compressor.
24. inspect for leakage with the sst (air leakage
tester). If there is no leakage, go to step 26. if
leakage is found at a loose joint, tighten and
then go to the next step.
25. inspect for leakage again. If there is no leakage
after tightening, go to the next step. If there is
still leakage at the same joint, discharge the
refrigerant and then repair the joint. Repeat
charging procedures from step 7.
26. remove the ssts 49 c061 006a，49 c061 007
from charging valves.
27. install caps back to the charging valves.
Refilling refrigerant
Attention
Do not exceed the specified scope when charging
system with refrigerant. Otherwise, it will cause low
efficiency of a/c system and damage the cooling
system recirculation components.
Charging with recycled r-134a refrigerant
1. connect r-134a recovery/recycling/ recharging
device to the vehicle and follow the device
manufacturer’s instructions.
Charging with new r-134a refrigerant
1. install ssts (charging device).
2. connect one end of joint pin of sst 49 c061 004
