or supplement conventional water heating systems (e.g. thermal ventilating

units supplied with hot water from a heat pump), the RE supplementary heating

element module can be used on all UTN thermal ventilating units.

The RE accessory is available in the following versions:

The RE module shown in figure (1) is mainly composed of:

A) Armoured finned heating elements made of aluminium, complete with

supporting brackets for fastening them to the load-bearing structure of the electric

module, which is built from thick galvanised sheet steel, duly insulated and

provided with an electric control panel for housing the power relays and wire

terminals. In conformity with electric safety directives, the module is equipped with

3 automatic-reset safety devices (one for each heating element) and one manual-

reset safety device.

B) An automatic-reset safety thermostat, integral with the heating element,

which switches it off should overheating occur as a result of irregular operating

conditions or a fault in the fan motor unit;

C) A manual-reset safety thermostat, mounted on the load-bearing structure,

which switches off the heating element in the event of a simultaneous failure of

all 3 automatic-reset safety thermostats.

Caution: the sensitive element of the manual-reset safety thermostat is a capillary

bulb that must be duly re-positioned, always in the top part, if the RE module is

installed in a configuration differing from the standard one. In the standard

configuration, the box housing the electric connections is situated on the same

side as the water connections. Therefore, viewing the machine from the front after

it has been installed, the electric module will be positioned on the machine itself

with the electric box on the left side. In this configuration, the thermostat bulb will

be in the correct position (factory configuration). If the electric module is installed

in the opposite position (electric box on the right), it will be necessary to move the

thermostat bulb into the position shown in figure (2); care must be taken to fasten

it securely with clamps, using the holes provided for this purpose.

D) An electric box incorporating the power contactors, connection terminals and

manual-reset thermostat.

E) L-shaped brackets and screws for fastening the module to the machine outlet.

The RE heating element must be associated with the following control:

INSTALLATION

Warning! Before starting the installation procedure, disconnect the thermal

ventilating unit from the power supply

THE RE ELECTRIC MODULE CAN BE INSTALLED ONLY ON THE MACHINE AIR

OUTLET

The overall dimensions are shown in figures 4a and 4b.

It is recommended to mount the RE module on the thermal ventilating unit before

installing the unit itself in place.

Place the thermal ventilating unit in an upright position. Fasten the L-

shaped brackets on the two short sides of the air outlet, using the 4 holes

provided (2 per side) and self-tapping screws (supplied in the kit).

After applying the 2 L-shaped brackets, which serve both as a guide and

support for the RE module, you can install the module itself; make sure

that the L-shaped brackets are both positioned inside the rectangular

outlet.

Apply the self-tapping screws (supplied in the kit) as shown in figure (3):

the screws on the short sides act on the L-shaped brackets, while on the

two long sides holes are provided for fastening the module directly to the

outlet of the thermal ventilating unit.

Description of controls

NOTE:

The electric module has holes like those on the machine air intake, on the

extremity turned toward the air outflow ducts. This allows you to attach all the

accessories that can be directly applied on the machine (PCOC, PCOF, GAT,

etc...).

Important: if you wish to install vibration-damping couplings use ONLY GAT

heat-resistant couplings

After fastening the electric module to the thermal ventilating unit, you can position

the latter in its final installation site and proceed with the wiring (see MICROPRO-

D manual).

Each thermal-ventilating unit requires a switch (IL) on the feeder line with a

distance of at least 3 mm between the opening contacts, and a suitable safety fuse

(F).

I) Open the electric box by loosening the 4 self-tapping screws on the front of the

cover.

II) Connect the electric wires, using the wire clamps provided, both for the power

supply line and the wire connecting to the control on the wall.

Important: The only control provided is the MICROPRO-D, which incorporates all

the necessary functions for managing the thermal ventilating unit, the heating

elements (and the on-off valves on the water side, where present).

NOTE: the MICROPRO-D control guarantees the complete safety of the RE

module, thanks to the POST-VENTILATION function, which keeps the fan

running for 2 minutes after the heating elements have been switched off

because the set temperature point has been reached. This feature serves to

prevent dangerous overheating which may be caused by the thermal inertia

of the heating elements themselves.

Galletti S.p.A. will not be liable for any faults or damage caused by improper use

of the RE module and/or an inadequate control panel.

If the module is applied on thermal ventilating units with plumbing connections

on the right (i.e. with the electric box on the right) it will be necessary to change

the position of the bulb of the manual-reset safety thermostat.

As noted above in item (C), if the electric module is installed in a position opposite

to the factory configuration, it will be necessary to move the thermostat bulb into

the position shown in figure (2); care must be taken to fasten it securely with

clamps, using the holes provided for this purpose.

In case of vertical installation, the safety thermostat bulb must be secured to

the wires of the automatic-reset safety thermostat (see fig 1 B) using the

clamps provided in the kit.

Warning: the control panel must be mounted on the wall in an easily accessible

position allowing the user to set the functions while ensuring an accurate reading

of the ambient temperature. Therefore, avoid:

- positions directly exposed to sunlight;

- positions exposed to direct currents of warm or cold air;

- placing obstacles that impede an accurate temperature reading (drapes or

furniture);

- constant presence of steam

- covering the panel or building it into the wall.

The minimum gauges of the power cables will depend on the electrical inputs

specified in table 1, in compliance with current regulations.

To guarantee the efficiency of a thermal ventilating unit fitted with a supplementary

RE heating element module, comply with the following directions:

- keep the air filter clean;

- do not pour liquids inside the equipment;

- make absolutely sure you do not obstruct the air outlet or inlet of the thermal

ventilating unit;
