Cooling/Heating Coil - CIAT Climaciat Instruction Manual

ƒ Pulleys and belts:
- The maintenance frequency for the belts depends on the fans' operating conditions.
- Check the belt tension and wear.
- Check that the motor and fan pulleys are correctly aligned.
ƒ Replacing the belts:
- Reduce the centre distance (diagram opposite) so that the V-belt(s) can be
positioned in the groove without forcing. It is forbidden to force them using a lever,
screwdriver or other tool.
- On pulleys with several grooves, if one of the belts is faulty or worn, all of the belts
must be replaced simultaneously. The V-belts used on a set of belts must all be of
the same make.
- If the fans are stopped for prolonged periods (more than three months), there is a
risk of bearing damage. To prevent this, we recommend reducing the belt tension
or temporarily removing the belts from the fan. When restarting the fans, the belt
tension must be readjusted to the specified value. Likewise, monthly rotation is
recommended to prevent the formation of a flat spot on the rollers.
10.3.3 Disassembling the fan motor assemblies
ƒ When disassembling the fan motor assemblies, use suitable lifting equipment and
comply with the safety standards.
