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:

supporting bracket, interrupting the operation only if the
automatic safety thermostat fails to operate;

Other elements of the kit:
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

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.
