Water Piping Connection
The indoor unit is equipped with water outlet and inlet threaded connection. There is an air-vent for air purging that is fitted at the
outlet water header.
3 ways valve is required for cycling off or bypass the chilled water.
Black steel pipe, polyuthrene pipe, PVC pipe and copper tube are recommended in field installation.
All types of piping and connection must be insulated by polyurethane (ARMAFLEX type or equivalent) to avoid condensation.
Do not use contaminated or damaged pipe and fitting for installation.
Some main fitting components are needed in the system to enhance the capacity and ease of service, such as gate valve, balancing
valve, 2 ways or 3 ways valve, filter, strainer, etc.
