Safe functioning is assured only when the installation procedures 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 meshes;
•all the fans installed at a height lower than 2.7 m from ground level must be equipped
by extra safety kits, which can be ordered and should be mounted on the fan side;
•there must be no obstacle neither in front or behind the fans. The outgoing airflow must
be kept free at least of a length of 3-times fan diameter and the ingoing airflow must be
kept free at least in a radius of 1.5 m distance in front of the fan;
•inform the maintenance operator on maintenance procedure; create an efficient ground
wiring; adopt disconnecting and safety automatic devices against overloadings and
short circuits.
WARNING
•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
C.E.I.64-2 rules and do not handle any material which might produce explosive
powders, as stressed in the same rules;
•if used as an air extractor, the emission of polluting gases into the atmosphere must be
within the limits determined by local authorities;
•fans must be installed at a safe height to leave the way free for the transit of transport
and operators.
WARNING The fan can be used by people (including children) with reduced physical,
sensory or mental capabilities, or lack of experience, only if adequately supervised or
instructed in the safe use of the device and with the knowledge of the associated risks.
Children shall not play with the fan.

3. BEFORE USING
3.1 Packaging and transport
Fans are packed individually in cardboard wrappers according to delivery requirements.
WARNING Always wear protective clothing and gloves during fans handling.
3.2 Structure
Air Circulators consists of the following components:
•sheet body riveted, without welding spots, in galvanised or precoated or stainless steel
304;
•six blades propeller in stainless steel 430 or galvanised or precoated EDC24;
•blades fixed with aeronautical rivets;
•asynchronous three-phases electric motor, 50, IP55 protection class, fixed speed;
•flow straightener;
•one or two safety meshes.
4. OPERATING CONDITIONS
Air circulators are designed to create air circulation inside farms and greenhouses and meant to
maintain both the environment temperature and humidity constant and uniform.
Working ambient temperature limits are -15°C to +40°C. Maximum altitude is 1000 m above sea
level. If a fan is 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.

7| © Munters AB, 2020
5. INSTALLATION
Circulators are delivered fully assembled. The fan is supplied without a control box; the installer
shall provide a suitable control box in compliance with the requirements specified by the EN
60439-1 standard.
Circulators are designed andbuilt for hanging installation andhave therefore eyebolts to be hung.
WARNING Always check up if cable and chain dimensions are suitable to hold up the
fans weight and if they have the proper length to distribute the strain uniformly (fig.1).
fig. 1
5.1 Connection to the electrical system
The fan is supplied without a command and control circuit, but with all the internal electrical
connections already made.
At the fitting stage, the installer must set up a control panel in compliance with the requirements
of standard IEC EN 60439-1, and arrange the wiring of the fan in accordance with the instructions
in standards IEC EN 60204-1 and IEC 60364.
The electrical panel of the fan must generally be equipped with the following devices (bearing
EC marking as per directive 2006/95/EC):

8. MAINTENANCE
Maintenance of circulators only consists in regular cleaning, as they do not contain parts needing
periodic lubrication: all the moving parts are either manufactured from self lubricating materials
or are sealed with lifetime lubrication.
Maintenance operations must only be carried out by qualified personnel, as:
•mechanical operator or assembler (for mechanical parts);
•electrician (for the electrical equipment).
All the maintenance operations must be carried out with:
•the power switch in the off position and locked by a padlock;
•the fan removed from work position after unhooking chains or cables;
•the propeller at a complete stand still before removal of protections;
•the use of ladders complying with the safety regulations in case of fans installed at a
certain height;
•a suitable equipment for maintenance operations.
Replacement of the propeller
If damage occurs, it is necessary to replace the whole propeller.
Replacement procedures of the propeller group in the EDC GHp model (see Chapter 9, fig. 10):
•loosen the fixing screws and remove the safety mesh;
•unscrew the bolts fixing the motor bracket to the body;
•pull the motor/propeller group out of the body and replace the damaged propeller;
•reassemble the circulator following the reverse procedure.
Functionality check of the thermo-magnetic switch:
•open the electrical control panel:
•check the absence of electrical continuity between the terminals upstream and
downstream the thermo-magnetic switch; in case of electrical continuity replace the
switch;
•close the electrical control panel;
•switch on the fan.
