Installation 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 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.

This is an option to be used in combination with Daikin units. Refer to
the installation and operation manual of the units for installation and
operation instructions.

Installation and maintenance should be carried out by technical
personnel qualified for this type of machine, in compliance with current
safety regulations.

When receiving the kit please check its state, verifying if any damage
occurred during transport.

Identify model and version of the electrical heater series from the
indications stated on the carton package.

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.

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:
n Electric heater assembly made of:

A Electric heating element with finned aluminium cladding,

designed for 230 V, 1-50 Hz power supply. The following table
shows the power consumption (equivalent to the heating
capacity) and the operating current;

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.

Notes on installation

Each unit requires a switch (IL) on the power supply line with a distance
of at least 3 mm between the opening contacts, and a suitable safety
fuse (F).

The minimum wire section of the power cables are specified in the
table below:

Model FW01 FW02~06 FW08~10

Gauge of power cables (mm2)

To guarantee the efficiency of a unit equipped with a supplementary
EEH heating element, comply with the following directions:

n On completing installation, make sure that the minimum airflow is

guaranteed.

Minimum air flow rate

(m3/h)

The maximum temperature of air intake into the unit is 25°C.

n Check the airflow rate periodically.
n Do not obstruct the air outlet or inlet of the unit in any way.
n Do not place damp or wet clothing on the air outlet grille of the unit
n Do not turn off the unit using switch IL or by cutting off power to

the entire electric system. This would disable the post-ventilation
function and thus the air and components in the vicinity of the
heating element would risk overheating. Always use the
controllers to switch off the unit.

n Keep the air filter clean.
n Do not pour liquids inside the equipment.
