INSTALLATION
• The fan must be installed according to the air direc-
tion label on the fan.
• The fan must be connected to duct or equipped with
a safety grille.
• The fan should be installed in a safe way and make
sure that no foreign objects are left behind.
• The fan should be installed in a way that makes ser-
vice and maintenance easy. N.B.! Consider the
weight and size of the fan.
• The fan should be installed in a way that vibrations
not can be transfused to duct or building. To provi-
de this, use for example a duct clamp.
• To regulate the speed, a transformer, a speed con-
troller or a frequency converter can be connected.
• A wiring diagram is applied on the inside of the junc-
tion box or separately enclosed. Connection accor-
ding to wiring diagram 4040128 is standard. For
reduced speed see wiring diagram 4040129 and
4040130.
• The fan is grounded, installed and connected elec-
trically in the right way.
• The motor has a built-in thermo-contact.
• Electrical installations must be made by an authori-
zed electrician.
• Electrical installations must be connected to a local-
ly situated tension free switcher or by a lockable
head switcher.
DESCRIPTION
ENGLISH
This directions for use contains following products:
LPKB 125 B/B-r, LPKB 160 K/K-r, LPKB 200 B/B-r, LPKB 200 K/K-r
and
LPKBI 125 B/B-r, LPKBI 160 K/K-r, LPKBI 200 B/B-r, LPKBI 200 K/K-r
LPKB and LPKBI are low profile duct fans with back-
ward curved impellers and swing-out design.
The fans are manufactured from galvanised steel
sheet.
LPKB and LPKBI has the same benefits, but LPKBI
is equipped with an in-built silencer and extended.
APPLICATION
• The fan is used for transportation of “clean” air, mea-
ning not intended for fire-dangerous substances,
explosives, grinding dust, soot, etc.
• The fan is equipped with an asynchronous external
rotor induction motor with maintenance-free sealed
ball-bearings.
• The capacitor has finite lifetime and should be ex-
changed after 45.000 operation hours (about 5 years
of operation) to secure maximum function. Defec-
tive capacitor can cause damage.
• Reduced speed is received through a capacitor cut-
over (see wiring diagram page 12). This must be
done by an authorized electrician.
• To achieve maximum life time for installations in
damp or cold environments, the fan should be ope-
rating continuously.
• The fan can be installed outside or in damp envi-
ronments. Make sure that the fan-house is equipped
with drainage.
• The fan is intended to be used at the highest volta-
ge and frequency that’s stated on the label on the
fan.
• The fan can be installed in any position.
