Operation procedures/pictures
Disassembling four-way valve
Screw off the fixing nut of the four-way valve
coil and remove the coil. Wrap the four-way
valve with wet sponge and weld off the four
weld joints on the four-way valve to take off
the four-way valve (Remarks: it is required to
discharge
completely
Welding process should be as quickly as
possible and the wetness of the wrapping
sponge should be maintained all the time. Be
sure not to burn out the lead wire of the
compressor as shown in Fig.8-45.
Disassembling Capillary
Weld off each weld joint of the main capillary
and auxiliary capillary to take off the capillary
as shown in Fig.8-46.
Disassembling big valve and small valve
Screw off 2 bolts that fix the big valve, weld off
the welding point between the big valve and
the air return pipe to take down the big valve.
Note: when welding off the welding spots,
wrap the big valve with wet cloth completely to
avoid high-temperature damage to the valve
body. Screw off 2 bolts that fix the small valve,
and weld off the welding point between the
small vale and the forked type pipe and take
down the small valve as shown in Fig. 8-47.
