Electrical Wiring Connection - Daikin FWT02CATNMV1 Installation Manual

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 fi tted at
the outlet water header.
3 ways valve is required for cycling off or bypass the chilled water.

Some main fi tting 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, fi lter, strainer, etc.
