ay kit
The kit of the motorized 3-way ON/OFF valve connected to the Daikin
controller allows to set the ambient temperature by interrupting the
flow of water directed to the heat exchanger.
The kit is available with various connections for all the FWV, FWL and
FWM units, both for 2-pipe and 4-pipe systems, as shown in the
following table:

The actuator must be coupled to a controller that, depending on the
type of system, can be chosen from one of the following:

The kit contains:
Body of the 3-way valve with 4 connections with built-in brass
!
bypass to withstand a maximum operating pressure of 16 bar.
Electrothermal actuator with the following specifications:
!
- power supply: 230 V
- activation: ON/OFF button
- total opening time: 4 minutes.
Hydraulic kit to install the body of the valve on the heat
!
exchanger, with 2 regulating valves (lockshields) to control the
water flow and close the water circuit when maintenance work is
conducted on the unit.
Bushing to arrange the cables inside the unit.
!
thermal insulation to prevent condensation on the hydraulic kit
!
during operation in cooling mode (only the valve of the standard
heat exchanger can work in cooling mode).

nstallation
To install the valve kit, proceed as indicated below.
1
Remove the outer covering frame.
All the electrical connections and components not supplied
must be performed by only a qualified electrician and in
accordance with the requirements of current applicable
national and local regulations.
All the powered circuits must be opened before you access
the terminals.
Warning
For the FWL + FWM units, remove the condensation container
!
before installing the valve.
For units with 4-pipe systems (2 heat exchangers), the additional
!
heat exchanger must be installed with the hydraulic joint on the
same side of the standard heat exchanger. In this case, first
install the valve of the standard heat exchanger and then the
valve of the heat exchanger with 1 extra row.

The valve kit has been pre-assembled to make it easier to
install.
Where required, the connections have been coated
!
with sealant material beforehand.
The connections have not been tightened to make
!
them easier to adjust.
After deciding the final position of the valve kit, tighten
!
all the connections to keep the kit watertight.
