、
After achieving the required vacuum effect, filling the refrigerant to the system with
refrigerant bottle. On the nameplate and main technical parameters we have marked
the suitable refrigerant. Make sure to fill the refrigerant at the low pressure side of the
system
c
、
The refilling refrigerant quantity subject to the ambient temperature. If you do not meet
the required filling quantity and cannot filling longer, you can turn on the machine, then
starting filling continuously from low pressure side, in the meantime must prevent
damage from liquid refrigerant.
2. Refill the refrigerant
Connecting the refrigerant bottle at the refrigerant injection needle valve of low pressure side
and connecting the pressure gauge at the low pressure side. Then turn on the machine, filling
the refrigerant into the system slowly and inspect the high and low pressure.
Warning: When doing leakage hunting and air tight test, only high pressure nitrogen
and refrigerant is allowed to use, filling oxygen, acetylene or other flammable or toxic
gases is strictly forbidden.
