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.
