Leak Test

Leak test must be made after connection of the refrigerant pipe according to the following diagram.
Close all the gas and liquid valves.To prevent nitrogen gas from invading the outdoor circulating
system,close the valve tightly before pressure increase,(Both the gas and liquid valves must be tightly
closed.)
Every cooling system must be charged slowly from the gas and liquid valves.

It must be charged from the gas and liquid valves.
