CONDENSER UNITS WITH
COMPRESSOR AND AXIAL FAN
OPERATION
START UP

Register the air inlet and outlet temperatures to the internal coil, the volts and amps of the compressor and
motor fan, as well as the suction and discharge pressure of each compressor.

Remember to clean the air filters after the first 4 hours of operation.

Observe, at least, 3 cooling cycle operations.

Since the unit is equipped with frequency converters it is essential that the protection is at least 300mA to
prevent power cuts caused by the activation of the circuit breaker.
INDOOR FAN TRANSMISSION ADJUSTMENT

Adjust transmission so that the indoor motor consumption reaches its normal value.

If consumption is below the nominal value it means that the unit air flow is too low.
- How to change the 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 a tensor screw or by sliding the motor, depending on the case.
-
Align fan and motor pulleys:
1. Loose the fan pulley set screws.
2. Slide the fan pulley along the shaft and align it with the motor by using a ruler in order to ensure that it is
parallel to the belt.
3. Tighten the fan pulley set screws.
