In case both welded belts break it is possible to use joint nipple as a temporarily quick repair solution until the welded
belt can be replaced with a new one. Depending of how the unit is installed, it may be not necessary to remove the
heat exchanger package in order to temporary repair a broken drive belt if the belt pulley can be accessed.
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.
