Safety Information

This machinery must not be put into operation prior to
reading mounting instructions and safety information.
All fans are intended for transportation of air in air
handling systems. If installed in non-heated rooms,
the fan casing has to be insulated in order to avoid
condensation. They are meant for use once built into
machinery or ducted systems and after a protection
grid has been installed. (EN ISO 13857). Fans with
duct connections must be connected to ducts on both
sides (inlet/outlet). Should there be a risk of water
entering the motor, via the ducts, external motor
protection is required. No moving parts shall be
accessible after installation. The fans are not to be
used in hazardous environments or connected to flue
ducts. The fans must not be installed outdoors, (with
exception of roof fans and fans with, for this purpose,
with corresponding IP class). Fans installed without
insulation in non-heated areas bear a risk a risk of
condensation. Safety accessories (i.e. motor
protection, safety grille) may not be removed, short
circuited or disconnected.
This appliance can be used by children aged from 8
years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience
and knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe
way and understand the hazards involved. Children
shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without
supervision.
Precautions must be taken to prevent the backflow of
exhaust gases from flues from other appliances
installed in the same room, which are fired by gas or
other fuels.
The appliance must be connected to a mains circuit
breaker in the fixed installation
CAUTION! Before servicing or maintenance, switch
off power, (all-pole circuit breaker), and make sure
the impeller has come to standstill. CAUTION! The
fans can have sharp edges and corners which may
cause injuries. CAUTION! Be careful when opening
the fans service-hatches (swing-out), the fan and
motor assembled on the hatch is relatively heavy.
CAUTION! Electrical reset.

Transportation and Storage

All fans are packaged at the factory to withstand
normal transport handling. When handling the goods
use suitable lifting equipment in order to avoid
damage to fans and personnel. Do not lift the fans by
the connecting cable, connection box, impeller or inlet
cone. Avoid blows and shock loads. Store the fans in
a dry place protected from weather and dirt until final

installation.

Installation
Refer to Safety information above. Installation,
electrical connection and commissioning are only to
be carried out by authorised personnel and in
accordance with requirements and demands.
Electrical connections are made according to the
wiring diagram in the terminal box, markings on
terminal blocks or on cable. All 3 phase fans are
delivered from factory in 400V 3~ connection.
CAUTION! Do not use metal compression gland
fittings with plastic terminal boxes. Use a dummy plug
seal for the compression gland fitting as well. The K-
fan must be installed with the connection box at the
top of the unit ± 90 degrees. If permanent installation
is carried out using cables with diameter 12-14 mm,
the entrance bush must be replaced (applies to type
K, KV, RVF and KVK 125/160). To preserve IP44 the
RS fans must not be mounted with the connection
box/motor plate upwards (Fig.1). Fans with thermal
contacts with external leads (TK) must always be
connected to external motor protection. Assemble the
fan in the direction of airflow (see arrow on unit). The
fan must be installed to ensure that any vibration is
not transmitted via the duct system or frame of the
building. (Suitable accessories such as fast clamps
and diffusers are available). Make sure the assembly
of the fan is firmly fixed and stable (Fig 3). The fan
can be mounted in any direction unless stated
otherwise. The fans must be installed to ensure that
service and maintenance can be performed easily
and safely. Disturbing noise can be reduced by
installing silencers (available as an accessory).
When using frequency regulation an all pole sinus
filter must be mounted between motor and frequency
controller (version all poles: phase to phase, phase to
earth). Fans are meant for continuous use within the
temperature range stated.
Fans with manual thermal contacts (reset by
disconnecting the power, motor protection SP1), must
be taken into consideration when connecting
surrounding equipment with automatic on/off function.
Recomended wiring for KT fans (Fig 2).

Operation

Before initial operation, check the following:
- Electrical connection has been properly completed.
- Protective conductor has been connected.
- Motor protection installed.
- Safety devices in place (protection grid)
- Leftover installation materials and foreign materials
have been removed from the casing.
When putting into operation, check the following:
- Connection data corresponds to the specifications
on the nameplate: Maximum voltage +6%, -10%,
according to IEC 38. Rated current must not be
exceeded with more than 5% at rated voltage.
CAUTION! When speed regulating by reducing the
voltage the motor current may exceed the rated
current at a lower voltage. In this case the motor
