Maico ERM 15, Mounting & Operating Instructions, Page: 4 / 8

Operating conditions
•
Installation location, installation position
The fan is used in ducts with DN100…DN 280
(depending on the fan type). It can be mounted
in any installation position in dry rooms. We
recommend the optional FUM mounting foot for
mounting. The overall unit may only be installed
in walls, ceilings, brackets etc. with sufficient
load-bearing capacity.
•
Protective grille
The fan/duct should be secured against the
danger of foreign bodies falling in or being
sucked in, in line with the safety requirements of
the 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).
•
Degree of protection
The fan complies with the degree of protection
indicated on the rating plate (IP54 or IP55) if
mounted horizontally, and, if mounted vertically,
with air flow direction downwards.
•
Temperatures
Please refer to the valid Maico catalogue for the
maximum permitted air medium temperature.
•
Rated voltage, Power frequency
The fan should only be operated using the rated
voltage and power frequency indicated on the
rating plate (230V, 50Hz).
•
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 3.5 mm at each pole.
Transport, Storage
•
When installing the fan, make sure that no loads
are placed on sensitive components, such as
the impeller or terminal box.
•
Maico will not consider any replacements or
guarantee claims in the event of incorrect
transport methods.
•
Storage: The fan should only be stored horizon-
tally in a suitable, dry room, with an ambient
temperature from –10 to +40 °C. Maico assumes
no liability for corrosion damage cause by
incorrect storage, for example, if the unit is
stored in a humid area. Long periods of storage
should also be avoided. Check the correct
functioning of the motor bearings before in-
stallation.
Installation
Notes
•
Airstream and rotational directions are indicated
by arrows marked on the fan housing.
•
Use ELM.. flexible cuffs to prevent transfer of
vibrations onto the duct system.
•
ERM22/DRM22: Use both the supplied reducers
(reduction to DN 200) for mounting.
Procedure
1. Prepare the ducting . Folded spiral-seams
ducts with a DN 100 to DN 280 diameter are
allowed, depending on the fan type. Use folded
spiral-seams duct with a diameter that matches
the fan. Please refer to the valid Maico catalogue
for dimensions. If necessary, separate any folded
spiral-seams duct at the installation site. If
necessary use REM.. reducers.
2. Installing a fan with a „FUM..“ mounting foot
on a wall, ceiling or bracket:
Secure the mounting foot at any position on the
fan housing using the self-tapping screws
supplied. Take note of the position of the termi-
nal box – it must be freely accessible.
3. Lay the folded spiral seams ducts flush
against the inlet flange, on the inlet and on
the pressure side.
4. Fasten folded spiral-seams duct to the fan
using the ELM.. flexible cuffs.
5. Attach an additional protection grille with
free inlet (see fig. 3 and 4).
