How To Handle; Installation - ONNLINE CK AC Instruction Manual

GB
This directions for use contains following
products: CK AC and EC.
DESCRIPTION
CK is a circular in-line duct fan with backward
curved impeller. The fan is equipped with
external rotor induction AC or EC motor with
maintenance-free sealed ball-bearings. The
fanhousing are manufactured from galvanized
steel sheet.
APPLICATION
• CK is accessible for the user, according to IEC
60335-2-40, to by themselves do the service
and maintenance, according to this Directions
for use. But before this work the unit must be
currentless. With reservation according to IEC
60335-2-7.12 "This appliance is not intended for
use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack
of experience and knowledge, unless they have
been given supervision or instruction concerning
use of the appliance by a person responsible for
their safety." "Children should be supervised to
ensure that they do not play with the appliance."
• The fan is used for transportation of "clean"
air, meaning not intended for fire-dangerous
substances, explosives, grinding dust, soot, etc.
• To achieve maximum life time for installations
in damp or cold environments, the fan should be
operating continuously.
• The fan can be installed outside or in damp
environments. Make sure that the fan house is
equipped with drainage.
• The fan is intended to be used at the highest
voltage and frequency that's stated on the label
on the fan.
• The fan can be installed in any position.

HOW TO HANDLE

• The fan must be transported in its packing until
installation. This prevents transport damages,
scratches and the fan from getting dirty.
• Attention, look out for sharp edges and
corners.
• Avoid extreme heat or cold (temperature range
for storage and transport

INSTALLATION

• The fan must be installed according to the air
direction 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
service 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 provide this, use for example a
flange.
• Electrical installations must be made by an
authorized electrician.
• See Wiring diagram at the lid of the junction
box.
• Electrical installation must be connected to a
locally situated isolator switch or by a lockable
main switch.
• Control that the fan is installed and connected
electrically in the right way, grounded and with
motor protection.
• For single phase fans a residual current device i
use (type A).
AC-MOTOR
• For speed regulation of AC motor a
transformer or thyristor can be connected.
• The AC motor has a built-in thermal contact.
• The capacitor (only for AC motor) has finite
lifetime and should be exchanged after 45.000
operationhours (about 5 years of operation) to
secure maximum function. Defective capacitor
can cause damage.
EC-MOTOR
• Speed
regulating of EC
motor can be
done with
the built-in
potentiometer,
0-10 V. An
external
potentiometer
can be
connected to
the terminal
if necessary.
