Installation and operation manual
Read this manual attentively before starting up the unit. Do
not throw it away. Keep it in your files for future reference.
Improper installation or attachment of equipment or
accessories could result in electric shock, short-circuit,
leaks, fire or other damage to the equipment. Be sure only
to use accessories made by Daikin which are specifically
designed for the use with the equipment and have them
installed by a professional.
If unsure of installation procedures or use, always contact
your Daikin dealer for advice and information.
The optional EEH (electric heater kit) cannot be mounted on
units which are set up for 2-pipe systems with 4-row coil and
4-pipe systems.
B
efore installation

Keep the unit in its packaging until it is ready to be installed, to prevent
dust getting inside.
Operating limits are shown here below; all other uses are considered
improper:
!
thermal fluid: water/glycol
!
water temperature: 5°C~95°C
!
maximum operating pressure: 10 bar
!
air temperature: 5°C~43°C
!
nominal power supply voltage: 230V - 50 Hz
Selection of location:
!
do not install the unit in rooms where inflammable gases are
present
!
do not let water spray directly on the unit;
!

i
nstallation
Before installing the fan coil, ensure that:
- The place of installation has sufficient space for
containing the device and for performing installation and
maintenance (respect spaces fig. point 2).
- The air inlet and delivery are not obstructed.
- The hydraulic connections are positioned and
dimensioned as requested by the device (fig.1).
- The electric power supply line has the features
requested on the fan coil’s data plate.
Remove the cabinet, where existing, by unscrewing the 4 fastening
screws reachable through the lifted side doors (see figure 2). In case of
FWL and FWR versions, also unscrew the 2 screws on the front panel.
Install the basic unit onto the wall/ceiling using the 4 mounting slots
and the supplied anchor screws, keeping the unit at least 100 mm
above the floor for a proper air suction and an easy pulling out of the
filter in case of FWV, FWZ, FWM and FWS models. In case of ceiling
models FWM, FWS, FWL and FWR verify that the installation height
corresponds to what is specified in figure 3, in order to avoid excessive
hot air stratification in the upper part of the room; in case of greater
installation heights we suggest to proceed with the back suction from
the lower part of the room. The installation heights refer to the
maximum running speed.
Carry out the hydraulic connections to the heat exchanger and in case
of cooling operation, to the water drainage system.
In case of cooling applications, make sure to insulate all field installed
piping and fittings as to avoid condensate dripping on the floor. Non
insulated piping can cause water damage!
We suggest to provide for the water inlet from the bottom side of the
heat exchanger and the outlet on the upper side.
For a better water drainage lean the drain pipe downwards at least
3þcm/m avoiding loops or narrowing on its way.
