Installation guide

8-2. Procedures (HR Module Installation Standard)

1) Before starting

(1) Check if all the service valves are closed (liquid, gas, high pressure gas, Oil Equalizing pipes).

(2) When using a nitrogen charging container, install pressure control regulator.

(3) R410a gauge manifold – minimum 4 units, manifold hoses – five units or more.

2) The following pipes should pass a leakage test.

(1) Liquid pipe

(2) Gas pipe

(3) High-pressure gas pipe

(4) Oil Equalizing pipe

3) Connect the prepared two manifold gauges and five hoses as shown below and

connect to each service valve.

(1) If due to the shortage of manifold gauge, you can’t test all the equal oil pipes at the same time,

then first test the three main pipes and perform final tests.

) Pressure up the inner area of the pipe to 4.1MPa for a leakage test and maintain

the pressure for 24 hours.

5) If there is no leakage for 24 hours, then depressurize to 1Mpa and maintain the

pressure. The reason is to prevent corrosion in the pipes.
