Heat Insulation - LG MULTI V ARWN80LA2 Product Data

* High/low pressure side is the ball valve that is opened and closed
by 1/4 rotation
Pipe joint (auxiliary parts): Securely perform brazing with a nitro-
gen blow into the service valve port.(Releasing pressure : 0.02
MPa or less)
Flare nut: Loose or tighten flare nut by using the wrench with
both ends. Coat the flare connection part with oil for the com-
pressor.
Cap: Remove caps and operate valve, etc. After operation,
always reattach caps (tightening torque of valve cap: 25Nm
(250kg-cm) or more). (Don't remove the internal part of the port)
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).
Liquid pipe
Gas pipe
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

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.
