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 chock, 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.
All field wiring and components must be installed by a
licensed electrician and must comply with relevant local and
national regulations.

Supplied to supplement conventional hot water heating (e.g. fan coil
units served by a heat pump). The optional EEH (electric heater kit)
elements can be used on 2-pipe system and 3-rows heat exchanger
units ((FWV, FWL, FWM, FWZ, FWR and FWS).
The kit shown in figure 1 consists of:
Electric heater assembly made of:
n
A Electric heating element with finned aluminium cladding,
designed for 230 V, 1-50 Hz power supply. The following table

E box containing electrical wiring and operating relays;
F set of intermediate heat-resistant plastic grilles;
G fuse support to be used for units with water connections on the
left;
H package of screws;
I sticker with the warning DO NOT COVER;
J additional fuse support to be used for units with water
connections on the right.
The EEH heating element must be combined with one of the following
controllers:
Features
LCD Display & keys
Digital inputs
Water temp probe
ECONOMY function on digital input
4th fan speed for 4 pipes system and water
valves
Relative Humidity probe
Serial communication (RS485 modbus)
Display backlight
Configurable digital outputs (voltage free)
0-10V outputs for floating devices
Clock - time zones
These controllers guarantee that the heating element will work safely,
thanks to the function of supplementing the hot water heating system
and the post-ventilation function. Refer to the manual delivered with
the dedicated controller for more information.

Important! Before obtaining access to terminals, all power
circuits must be interrupted.
Proceed as follows to install the electric heater
1 Remove the cabinet covering the unit, where present, and replace
the existing intermediate grilles with the heat-resistant grilles
supplied in the accessory kit. Figure 5 shows how to fix the heat
resistant grille on the cabinet.
2 Remove the front panel from wall-mounted models and the
condensation tray from ceiling-mounted models.
3 Install the heating element complete with its supporting brackets
on the shoulders of the heat exchanger (4 fastening screws). The
wires must come out on the side opposite the water connections.
4 Pass the wires of the heating element and safety devices through
the opening provided on the side of the base unit; make sure you
first thread the wires through the bushing (see figure 2, standard
configuration with water connections on the left).
If you are installing the heating element on a unit with water
connections on the right, it will be necessary to change the
position of the safety devices (see figure 3):
- the safety thermostat (B) must be installed on the front fin at
the bottom, always on the side where the wires come out;
- the fuse (C) must be installed using the new additional fuse
support (J) supplied with the kit and repositioned on the top
part of the heating element, on the side where the wires come
out.
