Rotating wheel heat exchangers generally require no maintenance. However, cleaning the ex-
changer occasionally is recommended. Damage to the blades should always be avoided.
10.3.1.
Rotating wheel heat exchanger
10.3. Maintenance
The rotating wheel heating coil is driven by a belt.
•
The belt must be under slight tension.
•
There must not be any faults or wear on the motor‘s pulley.
•
The pulley must be parallel to the circulating heating coil and must not twist.
10.3.2.
Belt drive for rotating wheel
Changing the drive belt
The drive belt for the rotating wheel heating coil occasionally has to be changed if it is faulty or
during maintenance work. In this case proceed as follows:
•
Remove the cover from the terminal box duct, carefully loosen the plug-in connections and then
remove the terminal box duct (see Fig. 11a). When removing the terminal box, make sure the
temperature sensor does not damage the rotating wheel heat exchanger (see Fig. 11b).
•
The rotating wheel heating coil can only be extracted by approx. 20 cm (see Fig. 12).
•
Remove the defective drive belt and replace it with a new one.
Note: see Technical Data (Sec-
tion 14) for the length of drive belt according to type of device.
•
Place the new round belt on the drum and turn the drum by hand to thread the belt through (see
Fig. 14).
•
Weld the ends of the belt using a welding paddle and clamp (see Fig. 15).
•
Then clean the weld with a cutter to ensure that the drive belt can run smoothly.
•
Place drive belt on the pulley. Make sure that the belt runs smoothly on the pulley.
•
Then slide the heating coil back into the device, screw down the terminal box duct and make all
plug-in connections again. Screw down terminal box and cover.
Important: Use only Poly Flex round belts, 8 mm with tension support, smooth type That
is the only way of ensuring silent operation.
