Procedure:
1. Prepare the ducting.
If necessary separate any
folded spiral-seams duct at the installation site.
Folded spiral-seams ducts with a DN 100 to
DIN 255 diameter are allowed, depending on the
fan type. Use folded spiral-seams duct with a
diameter that matches the inlet flange.
2. Installing a fan with a „FUR ..“ mounting foot
on a wall, ceiling or bracket:
– Fix both holders [3.1] to the fan with the
centring bolts [3.2].
– install the supplied strut [3.4] for the following
fans as shown in the illustration on page 2:
ERR 16/1 S, ERR 20/.., ERR 25/.., ERR 31/..
and ERR 35/..
– Install the fan unit with the mounting foot on the
wall, ceiling or bracket. Suitable fixing material
must be supplied by the customer.
– Line the fan up correctly in the ducting and fix
it on both sides with the locking bolts [3.3].
3. Lay the folded spiral seams ducts flush
against the inlet flange, on the inlet and out-
let side.
4. Fix the folded spiral-seams ducts to the fan
with the ELR.. flexible cuffs.
These serve to
avoid the transmission of vibrations to the ducting
system.
5. Fit a protective grille in the case of a free
inlet.
Electrical connection
•
Only qualified electricians are permitted to make
the electrical connections, according to the
wiring diagram on the back page of the
instructions.
•
Before working with terminal boxes, always switch
off the main fuse at the fuse box and post
warning signs advising not to re-apply power.
This is particularly valid where the switch is some
way away from the fan.
•
The connecting cable between the power source
and the terminal box must be a permanently laid
cable. The cables must be fed into the terminal
box so that the cable grommet fits tightly round
the non-metallic sheated cable. If the power
cable is not installed correctly, the protection
class indicated on the rating plate cannot be
guaranteed and no claims can be made under
the terms of the warranty.
Starting up, Function test
•
Before starting up:
– check that all screwed connections are tight.
– Check the air channel for dirt. If necessary,
clean the air channel.
– Check compliance with the Technical data.
•
After starting up, make sure the impeller is
running quietly and if necessary adjust
accordingly. It is also important to ensure that
there is a free flow of air.
Problems, Solutions
•
Main fuse:
Always check whether the mains
fuse is switched on in the case of a fault.
•
The thermal overload protection has been
triggered, the fan switches off.
Leave the device switched off long enough for
the motor and temperature limiter to cool down.
If the unit fails to restart or if it breaks down again,
remove the power and call on the services of a
trained electrician to identify and eliminate the
cause of the problem.
Maintenance
The device is maintenance-free.
Disposal
The fan contains some recyclable materials and
some substances that should not be disposed of
in the rubbish. After its lifetime has elapsed, dispose
of the device according to the valid regulations.
Technical Data
See the rating plate or the valid catalogue.
