• For lateral adjustment, loosen the centre screw and then adjust the rotor
laterally. Then retighten the centre screw.
If there is a problem with the rotor bearings, contact your retailer to see if
the rotor needs to be replaced.
Loosen the hatch to access the adjustment point.
• To replace the brush strip around the
rotor, remove the existing brush strip
by unscrewing the screws. Install the
new brush strip while spinning the rotor
by
hand.
• To replace the rotor belt, remove the old
rotor belt. Tape one end of the new rotor
belt firmly and then spin the belt so you
can join the two ends together with the supplied rivet.
HEATING COIL
The safety switches must be switched off and locked after the unit has been switched
off before starting any service work.
Function:
The air heater uses water to heat the supply air to the desired outgoing temperature.
The heater consists of a number of copper pipes with aluminium slats.
For circulation and regulation of the water, the heater is usually equipped with a
shunt group. To protect the heater from freezing, a strap-on freeze protection sensor
is mounted on the collection pipe.
Check:
• That the coil front surface is not dirty.
• That the pump is running and that the water is circulating and has
the correct temperature for the season. Check the sensor function.
• Function of freeze protection.
• That the slats are intact (not damaged).
• That the coil is not damaged and is not leaking.
Action:
• Clean with a vacuum cleaner fitted with a soft brush.
• Make sure that the strap-on sensor is correctly positioned.
Replace the strap-on sensor when needed.
• Adjust the slats with a “slat comb”.
• Turn off the water and empty the system through the coil’s drain valve.
Change
the
coil.
Remove the coil:
1. Turn off the unit via the control panel and place
the main power switch in position 0.
2. Switch off the shunt and close the cutoff valves.
3. Empty the system through the coil’s drain valve.
4. Remove the coil’s screw caps in the unit.
5. Pull out the coil.
