13.6 Installation, Relocation, and Service
13.6.1 Air purge and gas leak test for new installation (using new refrigerant pipes) using
vacuum pump
(From the point of view of global environment protection, do not release CFCs into the atmosphere during installation
work)
1. Connect the charging hose of manifold gauge to the service port of 3-way valve (pushing insect pin).
2. Fully open the handle Lo of manifold gauge and operate vacuum pump.
(If the needle of the low-pressure gauge reaches the vacuum immediately, check 1 procedure again)
3. Perform vacuuming 15 minutes or more, and make sure low pressure gauge reaches to -0.1 MPa (-76cmHg).
When the vacuuming completes, fully open the handle Lo of manifold gauge and stop the operation of vacuum
pump, and leave it for 1 ~ 2 minutes. Then, remove the connection side of the charging hose of vacuum pump
adopter after checking the needle of manifold gauge does not turn back.
4. Open the stem of 2-way valve to 90° in anti-clock wise, and close the 2-way valve after 10 seconds, and perform
gas leakage test.
5. Remove the charge hose from the service port of 3-way valve, and open the stems of 2-way and 3-way valves
(open the valves to anti-clock wise carefully, do not use full strength to open)
6. Tighten the service port cap with torque wrench 18
N•m (1.8 kgf•m)
Tighten the caps of 2-way and 3-way valves with torque wrench 18 N•m (1.8kgf•m)
7. After the tightening of each cap, check gas leakage around the cap.
