4.1 General
This manual concerns KVK Slim 200–500, KVK Slim 200–500 EC, KVK Silent 200–500, KVK Silent 200–500 EC manufac-
tured by Systemair Sverige AB.
The EC-fans are delivered with potentiometer, 0–10 V. The integrated potentiometer is factory preset to 10 V. This val-
ue can be changed manually to obtain a different motor rpm/fan performance. Fan performance charts for this purpose
are shown in the table by voltage steps (chapter 4.2.2). An external potentiometer or other controller can be connected
if necessary. If so the internal potentiometer needs to be disconnected from the connection terminals.
This manual consists of basic information and recommendations concerning the design, installation, start-up and opera-
tion, to ensure a proper fail-free operation of the unit. The key to proper and safe operating of the unit is to read this
manual thoroughly, use the unit according to given guidelines and follow all safety requirements.
The KVK Slim 200–500, KVK Slim 200–500 EC, KVK Silent 200–500, KVK Silent 200–500 EC are intended for transporta-
tion of air in air handling systems. The fans are meant for use in ducted systems and should always be duct connected
on the inlet side. No moving parts shall be accessible after installation. KVK Slim 200–500, KVK Slim 200–500 EC, KVK Si-
lent 200–500, KVK Silent 200–500 EC are adapted to continuous operation.
Danger
• The fans are not to be used in hazardous environments or connected to flue ducts.
• The appliance must be connected to a mains circuit breaker in the fixed installation.
• Switch power off (all-pole circuit breaker) before servicing or maintenance, and make sure the impeller
has come to standstill.
• Make sure protection grid has been installed (EN ISO 13857), no moving parts shall be accessible after
installation.
• Do not remove, short-circuit or disconnect safety accessories (i.e. motor protection, safety grille).
Warning
• The fans can have sharp edges and corners which may cause injuries. Be careful when opening the fans,
the motor assembled on the motor bracket is relatively heavy.
Caution
• Take precautions to prevent the back flow of exhaust gases from flues from other appliances installed in
the same room, which are fired by gas or other fuels.

4.3 Transportation and storage
All fans are packaged at the factory to withstand normal transport handling. When handling the goods use suitable lift-
ing equipment in order to avoid damage to fans and personnel. Avoid blows and shock loads. Store the fans in a dry
place protected from weather and dirt until final installation.
Warning
• The unit is heavy. Be careful during transport and installation. Risk of injury through pinching. Use
protective clothing.
• Do not lift the fans by the connecting cable, connection box, motor bracket, impeller or inlet cone.
5 Installation
Danger
• Make sure that the mains supply to the unit is disconnected before performing any maintenance or
electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Warning
• The units electrical connection to the mains supply must be preceded by an all pole circuit breaker with a
minimum 3 mm gap.
• Do not lift the fans by the connecting cable, connection box, motor bracket, impeller or inlet cone.
The fan can be installed in any directions. Mounting brackets and screws are delivered in the box together with the fan.
Make sure the assembly of the fan is firmly fixed and stable. 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). Electrical connections are made according to the wiring diagram in the terminal box, markings on termi-
nal blocks or on cable.
The connection box is mounted on a short cable for optional mounting on the casing of the fan (short or long side).

10 |Maintenance
5.1 Commissioning
Danger
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Before initial operation, check the following:
• Electrical connection has been properly completed.
• Protective earth has been connected.
• Safety devices in place (protection grid).
• Leftover installation materials and foreign materials have been removed from the casing.
Testing the installation:
• Adjustment may be required in the electrical compartment during test (i.e. changing of the potentiometer), however
during operation the lid must be closed.
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.
• Smoothness of motor operation, (no abnormal noises).
Sound levels exceeding 70 dB(A) may occur depending on size (see www.systemair.com for detailed information).
6 Maintenance
6.1 Important
Danger
• Make sure that the mains supply to the unit is disconnected before performing any maintenance or
electrical work!
• Fan impeller has come to a complete standstill.
• Should the supply cable be damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard
• The unit is heavy. Be careful during transport and installation. Risk of injury through pinching. Use
protective clothing.
• Do not lift the fans by the connecting cable, connection box, motor bracket, impeller or inlet cone.
6.2 Cleaning the fan
Warning
• Make sure that the mains supply to the unit is disconnected before performing any maintenance or
electrical work!
• Fan impeller has come to a complete standstill.
Caution
• Beware of sharp edges during maintenance, use protective gloves. Risk of injury through pinching.
The fan should be cleaned when necessary, at least once a year to avoid imbalance and unnecessary damage to the
bearings. The fan bearings are maintenance free and should only be replaced if damaged. Do not use a high-pressure
cleaner (steam jet) when cleaning the fan. Ensure that the fan impeller's balance weights are not moved or the fan im-
peller distorted. Listen for abnormal operating noise.
145899 | A007

Troubleshooting | 11
7 Troubleshooting
The following applies in case the fan has stopped:
• Try to restart the fan by cutting the power a couple of minutes.
• Ensure that the impeller is not locked. Disconnect the power supply, remove any obstacles. Check that the fan starts
after reconnecting the current. Should the fan not start please contact your place of purchase.
8 Deinstallation/dismantling
Deinstall and dismantle the fan in reverse order of installation and electrical connection
9 Disposal
♦Ensure material is recycled. Observe national regulations.
♦The device and the transport packaging are predominantly made from recyclable raw materials.
♦Disassemble the fan into its components.
♦Separate the parts according to:
• reusable material
• material groups to be disposed of (metal, plastics, electrical parts, etc.)
