When using the electric coil, BEP or a pre-
heating hydronic coil, it is necessary to move
the PT 1000 sensor on the fresh air intake to
upstream of the preheating element.
The PT 1000 sensor is provided in the prehe-
ating accessory. You must drill a hole in the
external air intake duct and then insert the
Notes on mounting the electric coil
The inlet of the heater must be fitted with a
fixed mesh or device that prevents touching
the air intake of the element.
The distance between the heater and an
elbow, a valve, a filter etc. must be at least
twice the diameter of the duct, otherwise
the flow of air through the heater might be
irregular and cause activation of the ther-
mal overheat protection.
The heater must be insulated as per the regu-
lations relating to ventilation ducts. The insula-
tion material must always be flame retardant.
The cover of the heater must be free of insu-
lation, so that the identification tag can be
clearly seen and the cover can be removed.
The installation area of the heater must
remain accessible to permit replacement
and servicing.
The minimum distance between the metal
casing of the heater and any wood or other
combustible material must be 30 mm.
sensitive element in the channel and then
seal the hole.
The probe cable must be taken to the elec-
trical equipment and connected to Terminal
T1 in the place of the standard probe
mounted inside the unit. Then disconnect
connector T1 of the internal probe and con-
nect the connector T1 of the external probe.
When DIP 1 is ON, the connector to replace
is the T3.
MAINTENANCE
The unit is maintenance-free and requires
only a periodic field test.
The electrical panel can be facing upwards
or sideways, at an angle of 90° max.
The panel must NOT face downwards.
OVERHEATING
When the thermal overheat protection with
manual reset is activated, you must take the
following measures: do not tamper with the
heater in any way, e.g. do not remove the
cover. Refer to an authorised electrician.
Disconnect from the mains power supply
and identify the cause for activation of the
overload device. The overload device can be
reset once the fault has been resolved.
