NSTALLATION
The overall dimensions are shown in figure 3.
Installing the kit
It is recommended to install the EDEH module on the thermal
ventilating unit before installing the unit in place.
1
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).
2
After applying the 2 L-shaped brackets, which serve both as a
guide and support for the EDEH module, you can install the
module itself; make sure that the L-shaped brackets are both
positioned inside the rectangular outlet.
3
Apply the supplied self-tapping screws as shown in figure 4: 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.
Wiring
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. Refer to the manual of the ECFWER6 controller.
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).
1
Open the electric box by loosening the 4 self-tapping screws on
the front of the cover.
2
Connect the electric wires, using the wire clamps provided, both
for the power supply line and the wire to the controller on the
wall.
The minimum gauges of the power cables will depend on the
electrical inputs specified in the table in paragraph "Characteristics"
on page 1, in compliance with current regulations.
Controller
Always use the ECFWER6 controller. This controller incorporates all
necessary functions for managing the thermal ventilating unit, the
heating elements (and the on-off valves on the water side, where
present).
Selecting the location of the controller
The ECFWER6 controller must be installed on a 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 (drapes or furniture) that prevent an accurate
temperature reading;
■
constant presence of steam;
■
covering the controller or building it into the wall.
M
AINTENANCE
To guarantee the efficiency of a thermal ventilating unit fit with a
supplementary EDEH heating element module, comply with the
following directions:
■
keep the air filter clean;
■
do not pour liquids inside the unit;
■
make absolutely sure you do not obstruct the air outlet or inlet of
the unit.
O
PERATION
Refer to the manual of the ECFWER6 controller.
Important! Before obtaining access to terminals, all power
circuits must be interrupted.
The EDEH electric module can only be installed on the air
outlet of the unit.
NOTE
The electric module has holes like those on the unit air
intake, on the extremity turned toward the air outflow
ducts. This allows you to attach field supplied
accessories to the unit.
Always use heat-resistant couplings if you wish to install
vibration-damping couplings.
The ECFWER6 controller guarantees the complete safety of
the EDEH module, thanks to the post-ventilation function,
which keeps the fan running for 2 minutes after the heating
elements have been switched off. This feature serves to
prevent dangerous overheating which may be caused by the
thermal inertia of the heating elements themselves.
Always check the position of the capillary bulb of the
manual reset safety thermostat. See the note "Sensor
position of the manual reset safety thermostat" on page 1.
