This directions for use contains the following product:
Low profile in line duct fan ’LPKB’
Read and save these directions.
INSTALLATION
DESCRIPTION
• The fan is used for transportation of ”clean” air,
meaning not intended for fire-dangerous substan-
ces, explosives, grinding dust, soot, etc.
• The fan is equipped with an asynchronous external
rotor induction motor with maintenance-free
sealed ball-bearings.
• To achieve maximum life length for installations in
damp or cold environments, the fan should be ope-
rating continuously.
• The fan can be installed outside with a weather
protecting cover or in damp environments. Make
sure that the fan-house is equipped with drainage.
• All ’LPKB’-fans are as standard, single phase 110-127
V 60 Hz.
• The fan can be installed vertically or horizontally.
• The fan is UL 705 ”Power Ventilators” approved,
E224370.
• The fan has rotating parts, therefore safety precau-
tions should be exercised during installation, opera-
tion and maintenance. Tighten all screws before
operation unit. USE HAND PROTECTION AND
STAY CLEAR OF SHARP EDGES.
• The fan must be installed according to all local and
national codes and the air direction label on the
fan.
• The fan must be connected to duct or equipped
with a safety grill.
• The fan should be installed in a safe way not to
cause vibrations or risking the fan to fall off.
• The junction box must be security fasten to the fan
with 2 screws.
• Ensure that the fan and junction box are easily
accessible for service after the installation.
• A wiring diagram is applied on the inside of the
junction box.
• Use this unit only in the manner intended by the
manufacturer. If you have any questions, contact
your manufacturers representative.
• Before servicing and cleaning unit, switch power
off at service panel and lock the service disconnec-
ting means to prevent power from being switched
on accidentally. When the service disconnecting
means cannot be locked, securely fasten a promi-
nent device, such as a tag, to the service panel.
• Installation work and electrical wiring must be
done by qualified person(s) in accordance with all
applicable codes and standards, including fire-rated
construction.
• When cutting or drilling into the wall or ceiling, do
not damage electrical wiring or other hidden utili-
ties.
• Ducted fans must always be ventilated to the out-
doors.
CAUTION! FOR GENERAL VENTILATION USE ONLY. DO NOT USE TO EXHAUST HAZARDOUS
OR EXPLOSIVE MATERIALS AND VAPORS.
WARNING! TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:

OPERATION
• Do not install this unit above a tub or a shower, if
it’s not marked as appropriate for the application.
•Never place a switch where it can be reached from
a tub or shower.
Before starting, make sure that:
• the fan is installed and electrically connected in the
correct way to ground.

MAINTENANCE
should be done without dislodging or damaging the
impeller.
• Make sure that there is no noise from the fan.
1. Make sure that there is electrical power to the fan.
2. Cut the electrical power and verify that the im-
peller is not blocked.
3. Check the thermo-contact/motor protector. If it is
disconnected the cause of overheating must be
located and taken care of.
4. ’LPKB’ is equipped with automatic thermo-protec-
tor which resets automatically when the motor is
back in normal working temperature.
5. Make sure that the capacitor is connected accor-
ding to the wiring diagram.
6. If the fan still does not work, the first thing to do is
to change the capacitor.
7. If nothing of this works, contact your fan supplier.
FAULT DETECTION
• the current does not exceed more than +5% of
what is stated on the label.
• No foreign object are placed in the fan and no
noise appears when starting the fan.
• Use this unit only in the manner intended by the
manufacturer. If you have any questions, contact
your manufacturers representative.
• Before service and cleaning of the unit, switch off
the power at the service panel and lock the service
disconnecting means to prevent power from being
switched on accidentally. If the service disconnec-
ting means cannot be locked, securely fasten a pro-
minent device, such as a tag, to the service panel.
• Consider the weight of the fan when removing lar-
ger fans to avoid jamming and contusions.
• The fan must be cleaned when needed, at least
once per year to maintain the capacity and to avoid
unbalance which may cause unnecessary damages
on the bearings.
• The fan bearings are maintenance-free..
• When cleaning the fan, high-pressure cleaning or
strong dissolvent must not be used. Cleaning
WARNING! TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
If repair must be made to the product, it has to be performed by a qualified maintenance person.
The fan is easy to open for cleaning
and service with the swing-out
design.
Loosen the screws a few turns,
without removing them.
Turn the motor bracket to the right
so the screws can go through the
key holes. Open the motor bracket.
When closing, turn the motor
bracket to the left so the screws
go into the smaller part of the
keyholes.
Tighten the screws.
