4.6.1 Temporary belt repair solution
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.
Note:
If the rotor motor is placed at the back of the unit, it is recommended to remove the heat exchanger to
change the drive belt, see chapter 4.6.1.2.
4.6.1.1 Heat exchanger mounted
1. Stop the unit by disconnecting the mains.
2. Open the front hatch.
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.
6. Press the drive-belt ends firmly towards each other to secure the nipple.
7. 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 6.
8. Close and lock the front hatch and connect the unit to mains.
9. Check that the alarm has ceased on the Control Display.
Note:
If the alarm remains, check the rotor sensor.
4.6.1.2 Heat exchanger removed

4. Pull out the heat exchanger towards you. Some force may be needed.
5. Remove the broken drive belt.
6. Apply the new drive belt around the heat exchanger.
7. Press the drive-belt ends firmly towards each other to secure the nipple.
8. 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 7.
9. Mount the heat exchanger. Don’t forget to reconnect the rotor power and sensor cables.
