2. SAFETY ASPECTS
WARNING Failure to respect safety or behavioral rules can produce hazardous
situations for users as well as damage to the machine and theplace where it is installed.
The fan must only be used if it is in perfect operating condition, by personnel who are
perfectly aware of the safety measures and possible hazards, and in strict compliance with the
instructions given in this manual.
2.1 Personnel requirements
Equipment may only be used by personnel who know and apply the specific requirements given
in the user and maintenance manual and the more general instructions contained in various
regulations for accident prevention and applicable legislation regarding safety in the workplace,
as well as other European Community directives incorporated by the member states into their
national legislation.
Knowledge and understanding of the manual and of the attached documents constitute an
indispensable tool for reducing hazards and promoting the safety and health of workers.
Personnel training
All operators engaged in the use of the fan must have received adequate information from the
employer relating to:
•risks to health and safety at work connected with the use of the machine;
•first aid procedures, fire precautions and evacuation of workplaces;
•devices provided for the safety of operators, and residual risks generated by the
machine.
In particular, the employer has the following duties:
•when assigning tasks to operators, to take into account their capabilities in the interests
of safeguarding their health and safety;
•to provide adequate means of protection;
•to require compliance by individual operators with the company rules and provisions
regarding safety and the use ofthe collective and individual protective measures at their
disposal;
•to ensure that normal and special maintenance operations, or in any event operations
necessary for machine safety, are regularly carried out.
All operators must take care of their own safety and health as well as that of other people in the
workplace who may be affected by their actions or omissions, in accordance with their personal
skills, and the instructions and means provided to them by the employer.
WARNING Unauthorized tampering/replacement of one or more parts of the machine,
or the use of accessories, tools or materials other than those recommended by the
manufacturer, are prohibited and release the manufacturer from all liability.
WARNING Operators must be trained to deal with the occurrence of possible faults,
malfunctions or dangerous conditions to themselves or others, and in such an event
must:

6| © Munters AB, 2020
•stop the fan immediately by operating the emergency stop device (mushroom-shaped
pushbutton/main switch mounted on the electrical panel);
•not carry out operations which are beyond their duties and/or technical knowledge.
2.2 General safety instructions
WARNING
•Safety devices must not be removed or rendered ineffective;
•the fan must not be started with guards removed;
•any adjustment or maintenance operation must be performed with the electrical isolating
device activated and locked in position with a padlock;
•any operation is prohibited which may cause arcing or sparks or other situations which
could start a fire;
•in the event of alarm signals resulting in the intervention of safety devices, the operator
must ask for immediate action by qualified technicians responsible for maintenance;
•user must ensure that the environmental and electricity supply conditions in which the
fan operates are always within the limits specified in this user manual;
•do not for any reason modify parts of the fan in order to fit additional devices.
2.3 Safety devices
In the process of designing and building the fan, the manufacturer adopted the necessary
technical solutions to ensure compliance with fundamental safety requirements: the object of the
risk reduction process was to ensure that the operator can use the fan in safety. The machine is
provided with protection devices of fixed type and is fitted with an actuator for the emergency
stop function.
Fixed guards
The fixed guards are solidly fixed to the structure of the machine and cannot easily be eluded:
the guards are fixed with systems which require the use of tools for dismantling.
Dimensions and positioning in accordance with the instructions in the standard UNI EN 13857.
WARNING Do not start the fan with fixed guards removed: the guards can only be
removed with special tools, by specialized and trained personnel and with the system
stationary (emergency system activated and electricity and hydraulic fluid isolated). At
the end of maintenance operations, the guards which were removed must be replaced correctly.
Emergency stop function
The machine must be equipped at the installation stage with an
electrical panel, on which must be installed an actuator for the
emergency stop function, which when operated brings
dangerous movements to a halt by isolation of the power
supply: the button must be mushroom-shaped and coloured
red, provided with mechanical restraint and released byturning.

containing electrical apparatus, to
highlight the risks to which an operator
could be exposed in the event of opening
the electrical panel (danger resulting from
the presence of live parts), the level of
voltage present, the prohibition of
tampering by unauthorized personnel and
the prohibition on the use of liquids on
electrical apparatus in the event of fire.

WARNING The user and the employer must comply with current national law in terms
of protection against daily personal exposure of operators to noise, by providing the use
of personal protective equipment (earmuffs, earplugs, etc.) if necessary, depending on
the overall level of sound pressure in the installation area, andthe daily personal exposure of the
employees. In areas where the overall sound level reaches excessive values, personal protective
equipment must be used.
WARNING The fan must only be used if it is in perfect operating condition, by
personnel, aged more than 14 years who are perfectly aware of the safety measures
and possible hazards, and in strict compliance with the instructions given in this manual.

3. BEFORE USING
3.1 Delivery check
Upon receipt, inspect the fan for external damage and if found, inform the forwarding agent
without delay. Check the data on all the rating plates, especially voltage and frequency. Turn the
propeller while the fan is switched off to verify smooth rotation of the propeller.
3.2 Packaging and transport
Fans are packed individually in cardboard wrappers according to delivery requirements.
WARNING Always wear protective clothing and gloves during fans handling.
Handling of the fans should not be done manually as the fans have no handles or grips.
Consequently, one of the following alternatives should be used:
•trolley;
•forklift;
•crane: fix two bolts in the M8 bushes situated on the fan housing and hook the lifting
cable over the bolts.
WARNING Make sure a steel cable or rope of adequate size is being used when the
fan is lifted by crane. Fan weights are shown in the technical specification table (see
section 7.2).
3.3 Structure
Air Circulators consists of the following components:
•riveted sheet body in Munters Protect coated steel without welding spots;
•propeller with six blades in Munters Protect coated steel; blades are fixed to the
propeller by high-strength pop rivets;
•asynchronous three-phases electric motor (single-phase on request), 50/60 Hz, IP55
protection class, fixed or adjustable speed;
•two safety meshes.

4. OPERATING CONDITIONS
4.1 Intended conditions of use
Fans are machines designed for moving air to control temperature and humidity in greenhouses
or rearing sheds by extraction, not under pressure. They can even be installed horizontally,
without altering or modifying their characteristics.
Normal ambient temperature limits are -15°C to +40°C. Maximum altitude is 1000m above sea
level. Should a fan be required to operate at a higher altitude, the loss in mass flow (heat
removing capacity) due to lower air density should be taken into consideration.
fig.1
The fan has been designed and built to operate in safety for the user, if used according to the
conditions intended by the manufacturer and stated in this user and maintenance manual.
NOTE For further information, please refer to the technical documentation attached to
this manual.
4.2 Non-permitted conditions of use
Total or partial failure to observe the instructions given in this manual could cause damage to the
fan and/or people.
The following uses are to be considered not permitted and improper:
•use in the event of faults and/or tampering with the installed safety devices;
•use by personnel not specifically trained;
•installation of the fan for extraction or circulation under pressure;
