Safety Information

This machinery must not be put into operation until 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 to be used after building
them into machines or duct systems or after contact
protection grid has been installed. (EN ISO 13857). Fans
with duct connections must be connected to ducts on
both sides (inlet/outlet). When there is a risk of water
entering the motor, via the ducts, external 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, corresponding IP class).
If the fans are installed without insulation in non-heated
areas there is a risk of condensation. Safety accessories
(i.e. motor protection, safety grille) may not be
dismounted, short cut or disconnected. CAUTION Before
servicing or maintenance, switch off power, (all-pole
circuit breaker), and make sure the impeller has come a
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.

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. The K fan If permanent
installation is carried out using cables with diameter 12-
14 mm, the entrance bushing 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 so that vibrations are not transmitted to
duct systems or frame of building. (Suitable accessories
like fast clamps and diffusers are available). Make sure
202341 (11-07-2012)
the assembly of the fan is firmly fixed and stable. The
fan can be mounted in any direction unless stated
otherwise. The fans must be assembled so that service
and maintenance can be performed easily and safely.
Disturbing noise can be avoided by installing silencer
(available accessory).
For 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 cutting the
current, motor protection SP1), must be taken into
consideration when connecting surrounding equipment
with automatic on/off function.
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 thefollowing:
- 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 windings are protected by the thermal contact.
The minimum static fall of pressure must observed.
- That the motor protection is functional. The direction of
rotation should correspond to direction-of-rotation arrow
(3 phase).
- Smoothness of motor operation, (no abnormal noises).
-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
Sound levels exceeding 70 dB(A) may occur depending
on model and size (see online catalogue at
www.systemair.com for detailed information)

Maintenance, Service and Repair

Before maintenance, service or repair make sure that:
- Power supply is interrupted (all-pole circuit breaker).
- Fan impeller has come to a complete standstill
- Observe personnel safety regulations!
- If the supply cord is damage, it must be replaced by the
manufacturer, its service agent or similarly qualified
persons i order to avoid a hazard.
The fan should be cleaned when necessary, at least
1/year to avoid imbalance and unnecessary damage to
the bearings. A filter will prolong the time interval
between each cleaning of the fan. (It is sometimes
recommended to install a filter guard). The fan bearings
are maintenance free and should only be replaced if

supervision.
