2.1 General
The safety of fans is assured by Munters in compliance with the safety requirements indicated by the CE label.
Safe functioning is assured only when the installation procedure and the instructions for use have been carefully
followed. The following points must be stressed:
• proper transport procedure must be followed;
• do not remove the safety mesh guards;
• all fans installed at a height lower than 2.7 m from ground level, must be equipped by extra CE safety kits,
which can be ordered;
• if the safety mesh is not installed, the manufacturer is exonerated from all responsability and the use of the
fan is considered improper;
• the maintenance operator must be kept informed on maintenance procedures;
• do not operate the fan without the safety mesh properly installed;
• do not operate the fan without having it firmly fixed to the structure or without complying with the safety
regulations for the electrical connection;
• do not install the fan in places where there might be explosion hazards as described by EN 60079 rules;
• do not handle any material which might produce explosive powders;
• the emission of harmful particles and / or gases into the atmosphere must be within the limits determined
by local authorities;
• the fan is intended to be installed and used by qualified personnel who are familiar with relevant safety
requirements;.
• safety equipment necessary for the prevention of accidents at the mounting and operating site shall be
provided by the buyer in accordance with the regulations prevailing in the local country;
2.2 Points to observe
The fan must not be driven by impulsive voltage (frequently on/off voltage). This impulse voltage causes an
excessive build-up of heat in the motor which can lead to motor failure. The temperature of the outer casing of the
motor may be hot to the touch during normal operation.
Safety aspects 2.
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.
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.

3.1 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. After placing the motor in the working position
(see section 5.1), turn the propeller by hand while the fan is switched off to verify smooth rotation of the propeller.
3.2 Packaging and transport of assembled fans
The fan has a self-supporting structure in galvanised steel and it is usually delivered without packaging. Upon
request fans can be delivered packed in cardboard boxes. Fans should not be permanently stocked one upon
the other, regardless if they are delivered with or without packaging. 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:
• forklift: before loading, make sure the forks are opened as much as possible to avoid bending of the fan
bottom panel;
• crane: fix two bolts in the M8 bushes situated on the sides of the fan housing and hook the lifting cable over
the bolts.
3.3 Structure
The fans consist of the following components:
• fan housing in galvanised steel without welding spots;
• propeller with four blades in stainless or galvanised steel; blades are fixed to the propeller by high-strength
pop rivets;
• motor: single-phase or three-phases; 50 or 60 Hz; B3 form; F class winding insulation, IP 55 IEC protective
class; asynchronous single-speed;
• pyramidal shape and flat meshes for protection on back and front side;
• wall/column mounting system with tilting mechanism (optional extra); to be used when the fan needs to be
mounted next to a wall or column;
• tilting mechanism with chain (optional extra); to be used when the fan needs to be suspended from the roof
of the structure.
Before using 3.
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).
WARNING

© Munters AB, 2013 9
Circulation fans, such as the MFS, are products to be used to circulate the air inside a structure, thereby creating
air movement inside the structure which helps to cool animals down during hot periods.
Normal ambient temperature limits are –25°C to +50°C. Maximum altitude is 1000 m 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.

5.1 Assembly of the fans
Fans are delivered with the motor in the transport position to minimise space usage during transportation. To move
the motor to its working position, it is necessary to follow the steps indicated below.
1. Unscrew the screws holding the flat safety meshes in place and open
the safety meshes.
2. Loosen the bolt in the motor plate closest to the centre of the fan
completely and remove it.
3. Loosen the remaining bolt in the motor plate slightly, but do not
remove it.
4. Swivel the motor 90° around the remaining bolt in the motor plate
and re-insert the bolt that was removed from the motor plate and
tighten it slightly.
5. Place the V-belt over the motor pulley and then partially over the
central pulley.
6. Rotate the propeller by hand so that the V-belt gets completely into
the groove on the central pulley.
7. Push the motor away from the centre of the fan to tighten the V-belt.
See section 8.3 for establishing the correct V-belt tension.
8. Tighten the two bolts in the motor plate so that the V-belt remains in
tension.
9. Close the safety meshes, re-insert and tighten the screws.
