Heating cycle
INDOOR FAN TRANSMISSION ADJUSTMENT

Adjust transmission in such a way that the indoor motor consumption comes to its nominal value.

If consumption is below nominal value it means that unit air flow is too low.
To change fan speed :
1. Remove the belt. Move the motor along its track (or loosen the tensor set screw) in order to release it.
2. Loose the set screws of the motor pulley and turn the movable flange. Open or close depending on the needs
(Open: speed decreases).
3. Tighten set screws.
4. Place the belt in the pulley channel. The closure or opening of the pulley could void the size of the prior belt. In
this case, replace it for other belt of the same profile and with the appropriate length.
5. Tighten the belt by using tensor screw or sliding the motor, depending on the case.
