Installation of Refrigerant Piping
Precautions for the installation of piping:
●
Use clean piping that is free from dust, moisture or any other substances.
●
Store all the pipelines needed for installation indoors, and keep two ends of pipelines
sealed till welding.
●
Pass copper pipes into the holes at wall and seal the holes to prevent dirt coming in.
●
Do not do ODU piping work on rainy days, lest that moisture and dirt would enter the
pipelines.
●
Try to reduce bended piping and use bends with larger radius.
●
When connecting refrigerant piping, the stop valve of ODU shall be closed
completely after refrigerant piping between ODU and IDU is done, and refrigerant
leakage test and vacuumizing process are finished.
