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 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;
• inform the maintenance operator on maintenance procedure; create an efficient ground wiring; adopt
disconnecting and safety automatic devices against overloadings and short circuits.
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
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

3.1 Packaging and transport
Fans are packed individually in cardboard wrappers according to delivery requirements.
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 304 on EDX18 and EDX26 models;
• six blades propeller in stainless steel 430 (except EDC18) or galvanised or precoated on EDC18 and
EDC24;
• blades fixed with aeronautical rivets (except EDC18 blades fixed with M6 screws class 8.8 or higher);
• asynchronous three-phases electric motor (single-phase on request), 50/60Hz, IP55 protection class,
fixed or adjustable speed;
• flow straightener;
• one or two safety meshes.
Before using 3.
Always wear protective clothing and gloves during fans handling.WARNING

Air circulators are designed to create air circulation inside farms and greenhouses and meant to mantain both the
environment temperature and humidity constant and uniform.
Working ambient temperature limits are -25°C to +50°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.
Operating conditions 4.

© Munters AB, 2013 9
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 and built for hanging installation and have therefore eyebolts to be hung.
fig.1
Electrical connection
Fans are supplied with all the internal electrical connections set, with the exception of the connection to the power
line through a thermo-magnetic switch adapted to the power of the motor.
Installation 5.
Always check up if cable and chain dimensions are suitable to hold up the fan’s
weight and if they have the proper length to distribute the strain uniformly (fig.1).
WARNING
The electrical cable must be tense inside the body to avoid any interference with
the propeller.
WARNING

fig.2
Usually motors installed on circulators are:
• single-phase or three-phases, 230V, 50/60Hz;
• three-phases, 400V, 50/60Hz.
5.1 Use
Risks connected to moving parts
All the moving parts are protected by a case or placed inside the body. Even in case of breakings (fan, blades,...)
there are no risks of injury for people.
Switching on and switching off
Switching on and switching off operations pass through not supplied equipments.
Operating conditions
Looking at the airflow rectifier, the propeller should turn clockwise (fig.3).
2 phases + ground 3 phases + ground
InstallationChapter5
Ground connection is required to be according to the EN 60204-1 regulation.WARNING
Fans should not be installed in places where children aged 14 years or less are
present.
It is forbidden to remove the safety meshes until all people are clear of the fans.
WARNING

fig.3
Emissions in the atmosphere
If used as an air extractor, the user should carry out the checks and fulfilments in compliance with the regulations
about the inflow of polluting substances into the atmosphere.
Cleaning
During cleaning operations the power switch must be in the off position and locked by a padlock. It is necessary to
perform periodic cleaning of safety meshes, airflow rectifier and blades using brushes or compressed air.
InstallationChapter5
In order to avoid any damage, cleaning the motor directly with water jets must
be avoided.
WARNING

After installation, follow the steps mentioned below to verify that the fan is working properly:
1. check if all the fans are secured tightly to the suspension;
2. ensure that all the necessary safety equipment is fitted to the fans;
3. ensure that all electrical connections are done properly and comply with local regulations;
4. note in which direction the propellers are supposed to turn;
5. remove all obstacles from the front and back sides of the fan;
6. ensure that all people and animals are standing clear of the fan;
7. turn the electrical power to the fans on;
8. observe the direction in which the propeller of each of the fans is turning;
9. turn the electrical power to the fans off.
Commissioning 6.
Do not attempt to correct any problem observed during the above mentioned
steps while the fan is in operation. Wait until the electrical power has been
switched off and the fan has come to a complete stand still. Lock the electrical
switch in the off position with a pad lock while working on the fan.

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 EDC18, EDX18, EDC24, EDX26 models (see Chapter 9,
fig. 5,6,7,8):
• 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.
Maintenance 8.
Do not operate the fan with the safety protections removed: safety meshes can be
removed only with specific tools by qualified technicians when the fan reaches a
complete standstill.
The fixing sytems of the safety protections are not interchangeable with other
devices. Therefore, if for maintenance reasons the user damages or loses any
component, this must be definetely ordered from the constructor as spare
parts and it cannot just be replaced with other components, even similar, not
supplied by the constructor itself. In this particular event the constructor refuses
all responsibility on consequent damages caused to things and people and
considers any kind of warranty lost.
