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.
