Electrical Wiring Connection - Daikin FWT02CATNMV1 Installationshandbuch

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.
Chiller
Wire connection to the controller board is as show in the wiring diagram on the respective terminal box.
The standard controller board comes with a VALVE jumper and a HEAT jumper. The system must be configurated as the
jumper selection listed below:
Cooling Mode & Valve Application
Cooling Mode & Valveless Application
Heatpump Mode & Valve Application
Heatpump Mode & Valveless Application
Example: If the unit is running "Heatpump Mode & Valveless Application", remain the HEAT jumper while remove the
VALVE jumper.
This is proposed wiring connection. It may change subject to the chiller unit and must comply with the local and national
code and regulations.
IMPORTANT : * These values are for information only, they should be checked and selected to comply with the local and/or
national codes and regulations. They are also subjected to the type of installation and size of conductors.
** The appropriate voltage range should be checked with data label on the unit.
There must be an all pole disconnection in the supply mains with a contact separation of at least 3mm.

• All wires must be firmly connected.
• All wires must not touch the water piping, or any moving
parts of the fan motor.
• The connecting wires to the indoor unit must be clamped
on the wire clamps as shown in the figure.
• The power supply cord must be equivalent to H07RN-F
which is the minimum requirement, and to be used in
protective tube.
