Functioning
The fan is switched on and off centrally using a switch
or a button (see also the wiring diagrams on pages
15 and 16). Depending on how the fan is installed,
air is either extracted from or fed into the rooms.
The fan is not designed for switching the
i
direction of the air flow.
Transport and storage advice
Transport should only be handled by authorised
•
specialists.
Maico will not consider any replacements or
•
guarantee claims in the event of incorrect
transport methods.
The Technical data in respect of weight and
•
dimensions must be taken into account during
transport. Please refer to the rating plate or the
currently valid Maico catalogue.
You should never stand underneath a raised
•
load.
Only lift fans using supporting parts. No load
•
should be placed on sensitive components, such
as terminal boxes.
Lift the fan evenly and without any sudden
•
movements.
Storage:
•
The fan should only be stored horizontally in a
suitable, dry room, with an ambient temperature
from –10 °C to +40 °C. Maico assumes no liability for corrosion damage caused by incorrect
storage, for example, if the unit is stored in a
humid area. Long periods of storage should be
avoided. Check the correct functioning of the
motor bearings before installation.
Operation conditions
Installation location, installation position
•
The fan is used in rectangular duct systems
with duct dimensions from 500 x 250 mm to
700 x 400 mm, depending on the model. It can
be mounted in a vertical or horizontal installation position in dry rooms. The complete unit may
only be installed in walls, ceilings, brackets etc.
with sufficient load-bearing capacity.
Temperatures
•
Please refer to the valid Maico catalogue for the
maximum permitted airstream temperature.
Protective grille
•
The fan and channel system should be secured
against the danger of foreign bodies falling in or
being sucked in, in line with the safety requirements of equipment and product safety
act. In the case of free inlet or outlet, you should
install a protective grille, in line with DIN EN 294
(DIN 31001).
Rated voltage and frequency
•
The fan should only be operated using the rated
voltage and frequency indicated on the rating
plate.
Rotating speed
•
Please refer to the current Maico catalogue for
speed control accessories.
Fixed electrical cabling
•
The fan may only be connected to a permanent
electrical installation. This must be fitted with a
mains isolation device that has contact openings
of at least 3 mm at each pole.
Thermal protection
•
The fan motor is thermally protected by a
temperature sensor (thermal contact or PTC
thermistor) in the winding.
It must be connected to an external control unit
with automatic switch-off, such as a motor protection switch for example or to a self-latching
contactor circuit. The control unit should not be
able to switch itself back on after being triggered.
In the case of overheating, the control unit
completely disconnects the fan from the power.
In this case, leave the fan switched off until the
motor and the temperature limiter have cooled
down.
Control units:
1. For motors with thermal contact (TK):
EPK .. : Maico motor protection swith MVE 10
DPK .. : Maico motor protection switch MV 25
2. For motors with PTC thermistor (K):
EPK .. und DPK .. :
Motor protection switch must be supplied by the
customer.
Please check out the Pressure / volumetric flow
•
tables on http://www.maico.de. The pressure
differential may not fall below the statistical minimum value as otherwise the motor warms up above
the permitted level.
