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 and motor impeller. 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, 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. Sound pressure level generated by the fan is on www.venture.pl.
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 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

Roof fans type ROOF-H
tel. [phone] www.ventur.eu fax. [phone]
●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 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. In case of impropper protection there is risk of sucking foreignt elements into the fan. Risk arising from damaging electrical
wires placed inside fan / air stream - e.g. using appriopriate construction grounding and security device in fan supply line.
•Capacitor (only single phase fans) is still energized for certain period of time after turning off the power supply.
•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 (if fitted) 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 need to be made in order to avoid impeller
jamming. In case of impeller jamming, fan need to be completely disconnected from power supply and repaired.
● After disconnecting from power supply fan still works for certain time (moveable parts are moving) as a result of energy accumulation.
1.2.11 Use
•Improper installation and/or use may lead to damage of the device and occurrence of dangerous situation. The unit can by installed,
maintained, dismantled and used only by qualified and authorized personnel, in accordance to safety rules and current regulations in the

3. ASSEMBLY AND INSTALLATION
3.1 General information
•During installation follow the guidelines contained in section 1.2
•The fan is a machine not ready for use (within the meaning of the Machinery Directive 2006/42/WE - before use of the device ensure
conformity with requirements of Machinery Directive 2006/42/WE. After installation the device must meet the requirements included in EN
ISO 12100, EN ISO 13857, EN ISO 13850 and EN 60204-1 standards. Additional information is included in Manufacturer Declaration (Appendix
E).
•Before installation remove temporary items that protect fan during transport and storage (e.g. box, foil, inlet and outlet caps –do not
remove any guards) –Starting the fan with those items could lead to damage of the fan. Make sure that the fan is not damaged.
•Ensure that there are no foreign bodies (e.g. mounting elements, tools) inside fan and near of the unit, the fan is properly secured after
installation (the cover of connection box and inspection cover are closed and secured, the connecting elements are properly tightened).
Technical acceptance need to be carried out in accordance with Appendix C.
3.2 Assembly information
•Fan need to by mounted in possition presented on Fig 2., with horizontal motor shaft possition (with motor base on bottom). Other montage
possitions are allowed only after manufacturer approval. Fan need to be mounted with use of outlet flanges (all holes placed in flange need to
be used) or with use of dedicated feets (all holes in mountign feets need to be used). Fasteners secured against loosing need to be applied.

Mounting position
A - mounting holes
B - mounting base
•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.
•It is recommended to apply measures minimizing transmission of vibration from/to the fan. For fans placed on vibro-isolators connecting on
inlet and outlet side need to be made in flexible form.
•Keep safe distance between installed device and inflammable elements (special attention to hot surfaces of device need to be paid).
•Keep free space from the fan outlet to allow free discharge of the pumped medium.
•Measures protecting user from burn by hot elements need to 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 operation manual and on motor markings - those guidelines need to
be applied.
• The voltage and frequency of the fan power supply network must not exceed those given on the fan nameplate.
Single-phase motors are equipped with a bimetallic temperature sensor located in the stator winding. Sensor tip are placed in the motor
terminal box (additional cube). This sensor should be included in the power supply circuit fan protection (e.g. transmitter, contactor, etc.).
Despite the use of a bimetallic sensor, it is necessary to connect an overload fuse to protect the motor against excessive overload. Switch
setting must comply with the maximum allowable current indicated on the motor's nameplate. Three-phase motors are equipped with a PTC
resistance temperature sensor. The sensor terminals are placed in the motor connection box (additional cube). This sensor should be included
in the fan protection supply circuit (e.g. by using a PTC transmitter). Despite the use of a PTC sensor, it is necessary to connect a motor
protection (short-circuit-overload protection) to protect the motor against excessive overload. The switch setting must comply with the
maximum allowable current indicated on the motor's rating plate.
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 change proper
power supplying wires in junction box.
