Performing Leak Test And Insulation - Samsung AM160FNBDEH Installation Manual

Performing leak test and insulation

Before completing the installation (insulating hose and pipes), you must check for gas leakage and when there is no leakage,
you may insulate the pipes and hoses.
Leak test
Use a gas detector to check the connection part of the pipes for gas leakage.
Insulation
Selecting the insulator of refrigerant pipe
Insulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size.
The standard temperature and humidity condition is 30 °C with humidity below 85 %. If the condition is in high humidity,
use one grade thicker.
Pipe Pipe size (mm)
Ø6.35~Ø9.52
Liquid pipe
Ø12.70~Ø19.05
Ø6.35
Gas pipe
Ø9.52 ~ Ø28.58
1. To avoid condensation problems, wrap each pipes with heat-resisting
polyethylene foam.
- Make sure that the opening part of the insulation to face up.
2. Wrap the refrigerant pipes and drain pipes with insulator.
