Thermal overload protection
The fan motor has thermal protection
(temperature sensor in the motor winding).
The overload protection automatically
switches the fan off in the event of
overheating.
The fan must remain switched off long
enough for the motor and temperature limiter
to cool down, before starting the fan back up.
Depending on size and temperature
conditions, it may take up to 10 minutes to
cool down. Only then can the unit be
switched back on.
3.3 Intended use
ERK are duct fans for usage similar to that
●
found in domestic properties.
They can be installed in any position.
●
The fans are used for air extraction or
●
ventilation, for example in productions
sites, workplace applications, storage
rooms, labs, workshops, rest rooms or
rooms without windows.
IP X4 type protection is only satisfied
●
when installed in ventilation ducts, on the
inlet and outlet sides with at least 1 m of
duct.
They can only be operated with an
●
ERK fan installed directly in the duct.
Folded spiral-seam ducts of a nominal size
appropriate to the unit are permitted for
the duct.
The ERK fan must be permanently
●
installed and the electrical supply cable
permanently laid.
A mounting foot [5] should be used for
●
installation. The mounting location must
demonstrate sufficient load-bearing
capacity.
3.4 Predictable misuse
Maico is not liable for damages caused by
use contrary to the intended purpose. Under
no circumstances should the unit be
used:
for conveying steam-saturated air or
●
greasy air,
for conveying solid particles which may
●
stick to the fan.,
close to flammable materials, liquids or
●
gases,
for conveying chemicals, aggressive
●
gases or vapours,
in explosive atmospheres,
●
outdoors,
●
with a free air entry or exit, if there is no
●
protection against accidental contact with
the impeller
in accordance with EN ISO 13857.
IP X4 type protection is not satisfied
when the ventilation duct on the air
outlet side points straight up and
there is no duct bend to prevent the
supply of moisture.
