Electric heater kit
The kit shown in figure 1 consists of:
■
Electric heater assembly made of:
A 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 metal, 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 automatic reset safety devices (one for each
heating element) and one manual-reset safety device.
B an automatic-reset safety thermostat mounted on 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 automatic-reset safety thermostats.
NOTE When the manual reset safety thermostat has tripped,
it can be reset as follows: (See figure 1)
1. unscrew the black cap inside the electric box
2. press the white button to reset the manual-reset safety
thermostat
3. re-install the black cap.
Sensor position of the manual reset safety thermostat
Even if the electric heater is not used in the standard
configuration, the sensor of the manual-reset safety
thermostat always needs to be positioned in the top part of
the electric heater. This means that for some applications,
the sensor will need to be re-positioned. See figure 2.
■
Standard (horizontal installation). (See figure 2-1)
Electric box of electric heater is at the same side of
the standard water connections of the unit. No need to
reposition the capillary bulb.
■
Non standard (horizontal installation)
Electric box of electric heater is at the opposite side of
the standard water connections of the unit.
Reposition the capillary bulb according to figure 2-2.
■
Non standard (vertical installation)
Reposition the capillary bulb on the top of the
automatic-reset
figure 2-3 and figure 2-4.
If more than 1 heating element, always select the top one
looking in the airflow direction.
If the capillary bulb needs to be repositioned, take care to
fasten it securely with the provided clamps using the holes
foreseen 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
unit outlet,
F sensor of the manual-reset safety thermostat.
