1.2 General risk and guidelines
During entire fan life cycle pay particular attention to the risk and guidelines presented below:
1.2.1 moveable components
The fan is equipped with moveable components (impeller of the device, impeller of the motor). Contact with them may cause
serious injury or death. The fan must not be used if covers (grids) and safety measures against contact with rotating parts have
not been installed.
1.2.2 suction
The fan has high suction power. Clothing, hair, foreign particles, and even body elements can be easily sucked in. It is forbidden to approach
the fan in “loose” clothing or reaching toward inlet of working fan. It need to be ensured, that no foreign body can be sucked in.
1.2.3 thrown elements
The air at the outlet of the fan has high energy. Elements sucked or placed inside the fan can be thrown with a high speed. The fan has stable,
solid construction, but as a result of damage or improper use some parts (elements with high kinetic energy) may be thrown away. Make sure
that before start and during operation of the fan there are no elements, that may be sucked in (pay special attention to fan inlet side) and
there are no person in stream of transported medium (on inlet and outlet side). Do not use fan without proper inlet and outlet covers (grids).
1.2.4 sharp edges
During manufacturing the fan sharp edges was grinded. However the fan may have edges touching which may cause injury.
We recommend the use of relevant protective gloves.
1.2.5. inertness
The fan has a high inertness. In case of no permanent fix turning on the fan will lead to it uncontrolled movement. The unit can be turn on
only after proper installation.
1.2.6 noise
The sound pressure level is dependent on the operation point. Check the sound pressure level and if necessary use silencers and/or individual
protection measures for personnel.
1.2.7 materials
In case of fire or transport of improper medium –fan parts can generate fumes hazardous to health.
1.2.8. environment
The fan can make over and under pressure. In areas where a specified air pressure and the quantity of air are required (e.g. in places with
combustion) make sure that there would be no deficit/excess of air.

1.2.9 temperature (hot surfaces)
The housing and fan elements take the temperature of transported medium. During work (e.g. as a result of compression
process) the temperature of medium, housing and fan components increase. Electric motor may heat up to high temperatures
(especially when overloaded/overheated). The appropriate steps need to be made to prevent from fire and burns caused of
high temperatures. In case of fire –to extinguish a fire use fire extinguisher approved for electrical equipment and follow
recommendation of fire department.
1.2.10 unexpected start / connecting power supply
● Before undertaking any kind of work on fan (e.g. installation, maintenance and inspection, disassembly), it has to be completely
and reliably disconnected (isolated) from power supply (check there is no voltage). It has to be ensured, that power supply will
not be connected during work on fan and moveable parts are not moving.
The appropriate steps need to be made in order to provide protection against electric shock and to prevent from access to electrical
components by unauthorized person.
●Fan is not equipped with control system –the connecting of power supply causes immediate start-up. The device is not
equipped with system, that would permanently shut it down in case of temporary power supply loss. It has to be ensured, that
any dangerous or unpermitted event does not occur in case of temporary loss of power supply.
●Thermal sensors installed in motor after tripping caused by motor overheat turn back to initial state after cooling down. It has to be ensured,
that any dangerous or unpermitted event does not occur in case of action of thermal sensors and after motor cooling down.
●In case of impeller jamming –its unblocking may cause sudden movement. Appropriate steps should be made in order to avoid impeller
jamming. In case of impeller jamming, fan should be completely disconnected from power supply and inspected (section 5).
●After disconnecting from power supply fan still works for certain time (moveable parts are moving) as a result of energy accumulation.

B –Inlet, outlet
C–mounting flange
Supporting construction has to be solid enough in order to carry the weight of the fan and generated vibration (including fan damage). The
fan cannot be exposed to vibration.
Inlet and outlet covers preventing from touching of impeller and touching of motor hot surfaces need to be applied, according to current
edition of ISO 13857 standard. Proper covers preventing from sucking and throwing of elements (see point 1.1.2 and 1.2.3) need to be applied.
The covers need to be made in accordance with IP20 according to EN 60529. If there is still risk of suction foreign elements –apropriate stpes
need to be taken (eg. air filters). Fan covers need to bemade in fixed version.
It is recommended to apply measures minimizing transmission of vibration from/to the fan such as vibro-isolators and flexible connectors.
For fans placed on vibro-isolators connecting on inlet and outlet side should be made in flexible form.
At least 3 inlet diameters distance should be maintained between inlet, outlet and obstacles (e.g. walls, ducts bend). 3 diameters distance is
important for correct fan air vlow, and correct motor cooling.
Keep safe distance between installed device and inflammable elements (attention to hot surfaces of device should be paid).
Measures protecting user from burn by hot elements should be applied.

3.3 Electrical connection guidelines
The fan and power supply network must be protected in accordance with local law requirements.
Detailed guidelines related to electrical connection are located in motor documentation and on motor markings - those guidelines need to be
applied.
The motor leads , ground (earthing) and PTC thermistor terminals from motor terminal box(conduit box) have been carried out
on the fan housing by a electrical wire. Power supply (L1, L2, L3), ground (PE), thermal sensors (PTC - PTC).
Protection against short-circuits, protection against overload and voltage asymmetry need to be applied. Emergency safety switch (isolator)
near the fan should be applied.
Use appropriate protection against electric shock. Fan need to be connected to grounding system.
Fan grounding terminal (PE - placed on the end of electric wire) need to be connected to grounding system.
Voltage and frequency of supply network cannot exceed those indicated on the fan nameplate.
Eectrical wire need to be placed in way that liquid (e.g. from condensation) does not run over it in the cable gland.
Fan is equipped with type 3xPTC sensors (serial connection): PTC sensor resistance grows rapidly with exceeding of permitted motor
temperature value. Ends of sensors need to be connected to system, which shuts down power supply in case of exceeding permitted motor
temperature.
3.4 Impeller rotation direction
Make sure that after installation and during using the fan the impeller would rotate in correct direction. After mounting fan to proper
construction, with special care taken and in accordance with sector 1 and 4, launch the fan in impulse way (less than 1 second) and check, if
the impeller rotates in correct direction, generating airflow in proper direction. The work with impeller rotating in the wrong direction reduces
fan parameters and may damage it. In case of improper impeller rotation, turn of power supply, wait until impeller stops and swap proper
power supplying wires.
4. USE
4.1 Use guidelines
Make sure that turning on of the fan does not make any hazard for personnel and property. Follow the guidelines featured in section 1.2.
The fan is designed for continuous operations (S1) –too high frequency of starting a fan may lead to motor overheat and damage.
Fan cannot work with voltage, frequency, current higher than shown on the fan nameplate (even if motor nameplate/manual allows it).
Applying of higher frequency may cause motor damage or mechanical damage of the fan.
Voltage regulation is not allowed - it may cause e.g. lack of fan start-up and motor damage.
The device cannot work with current consumption exceeding the value indicated on the nameplate.
In case of activation of any electrical protection, detection of damage, unit must by immediately turn out off use.
The device is adapted to work in certain range of characteristic. Too low volume flow rate of medium, start/work of device with completely
closed inlet and/or outlet may lead to motor overheat caused by current consumption exceeding value on the rating plate (current consumed
by fan grows as resistance of installation increases)
