Installation of Outside Units
4) Service port: Make the refrigerant pipe vacuum and charge it using the service port. Always reattach caps
after completing work (tightening torque of service cap: 14Nm (140kg-cm) or more).
5) Liquid pipe
6) Gas pipe
7) Elbow joint (field supply)
CAUTION
After installing the pipe, block the pipe escape of front and side panel. (It can cause mouse or other animals to
enter and cause damage to the wire.)
* Remove the front panel before pipe connection
* Must check the pipe (liquid pipe, gas pipe, high/low pressure common pipe) before pipe connection
Step 6) Heat Insulation
1) Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance(Over 120°C)
2) When installing in a humid environment, use thicker heat insulation material.
* Consult with LG on detailed technical specification.
