Plumbing materials and storage methods

Pipe must be able to obtain the specified thickness and should be used with low
impurities.
Also when handling storage, pipe must be careful to prevent a fracture, deformity
and wound.
Should not be mixed with contaminations such as dust, moisture.
Refrigerant piping on three principles
Should be no moisture
Items
- Significant hydrolysis of refrigerant oil
- Degradation of refrigerant oil
Cause failure - Poor insulation of the compressor
- Do not cold and warm
- Clogging of EEV, Capillary
- No moisture in the pipe
- Until the connection is completed,
the plumbing pipe entrance should
be strictly controlled.
- Stop plumbing at rainy day.
Countermeas - Pipe entrance should be taken
ure side or bottom.
- When removal burr after cutting
pipe, pipe entrance should be
taken down.
- Pipe entrance should be fitted cap
when pass through the walls.
