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:
•
Open the left door and remove the cover of the terminal box. (see Fig. 15)
•
Only for RotoK1000H, RotoK1700H: First remove the covers of the cabel duct, then loosen the
cnnection of the lower control board and then also remove the control board. (see Fig. 15)
Note: see Technical Data (Section 15) for the length of drive belt according to type of device.
•
Remove the cover of the revision opening. (see Fig. 16)
•
For changing the round belt, please proceed as follows: Place the new round belt on the drum,
fix it in place with adhesive tape and turn the drum by hand to thread the belt through (see Fig.
17).
•
Weld the ends of the belt using a welding paddle and clamp (see Fig. 18, 19).
•
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.
•
Mount the lower control board and the cover back in the unit, screw the cable duct back on and
re-establish 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.

Check the operation of the control system and safety devices.
•
Check electrical connections and wiring for damage.
•
Remove any dirt from the fan impeller or impellers and from inside the fan housing in order to
prevent any unbalance or reduction in output.
1.
Do not use aggressive or easily flammable products for cleaning (impellers/housing).
2.
Preferably only water (not flowing water) or mild suds should be used.
3. The impeller should be cleaned with a cloth or brush.
4.
Never use a high-pressure cleaner.
5. Balancing clips must not be moved or removed.
6.
