FLOW REGULATION IN THE FANS
The fan in the outdoors units KVCK/ KVHK/ KVHA 32E- 38E- 64D- 76D- 86D- 100D have a variable pulley
incorporated into the activating motor, by which it is possible to vary, when the fan is off its diameter to modify
the air flow of the unit, as required.
1. Fixed part
2. Mobil part
3. Fixing screw
CLOSE PULLEY:
To increase the fan flow, turn the mobil part in
direction "B" (Clock wise).
OPEN PULLEY:
To reduce the flow, turn in direction "A"
(Unclock wise).
TENSION OF BELTS
The belts can be easily tensioned through the tensing
screw incorporated into the bases of the motor of the
transmitting units which also enables a good servicing to
be carried out.
When the tensing screw is moved, the motor fan is moved
to the sides in order to tension the pulley.
