Accessories - Daikin FWB 02JT Installation And Operation Manual

VALVES KIT FEATURES
The 3-way motorized ON/OFF valve kit, connected to the Daikin controllers, permits to set the room
temperature by cutting off the water flow to the heat exchanger.
The kit is available in various fittings for all FWB units, both for 2-pipe and for 4-pipe systems.
The KIT Consist Of
3- way valve body with 4 connections with built-in by-pass
made of brass, maximum working pressure 16 bar.
Electro thermal actuator having the following specifications:
power supply: 220-240 V,
activation: ON/OFF,
total opening time: 4 minutes.
Hydraulic kit for the installation of the valve on the heat
exchanger, complete with 2 regulating valves for adjusting the
water flow and for closing the water circuit when performing
maintenance to the unit.
Bushing for routing the cables of the actuator inside the unit.
Thermal insulation to prevent condensation on the valve kit when
it operates in cooling mode (only the valve of the standard heat
exchanger can work in cooling mode).
The flow resistance of the connecting valve/hydraulic kit assembly is obtained from the following formula:
2
P = (Q /K )
w w v
Where:
P is the flow resistance expressed in kg/cm
w
Q is the water flow rate expressed in m
w
K is the flow rate identified in the table
