9.3 Replacing rotor drive belt
If the alarm Rotor guard is raised, see chapter 8.7.2.3, the rotor drive belt may be damaged or broken.
Fig. 10 Rotor drive belt
The replacement drive belt (1) is adjustable and delivered with a nipple attached in one end.
1. Stop the unit by disconnecting the mains.
2. Open and remove the side cover.
3. Remove the broken drive belt.
4. Use tape to attach the drive belt to the rotating heat exchanger, and rotate the exchanger by hand to get hold of the
drive belt.
5. Remove the tape and put the ”empty” end on to the nipple. Press the ends firmly towards each other and tighten the
nipple.
6. Pull the drive belt on to the belt pulley and rotate the exchanger by hand. Check that the belt pulley rotates.
Note:
If the drive belt slips, the drive belt may be too long and needs to be shortened. Cut the drive belt 5 mm
and go to step 5.
7. Replace and lock the side cover and connect the unit to mains.
8. Check that the alarm has ceased on the Control Display.
Note:
If the alarm remains, check the rotor sensor.
