2. Switch on the voltage. Start the compressor and stop it immediately. Check the rotation
direction of drive motor (M1) while the motor is coasting to a stop. The correct rotation
direction of the drive motor is indicated by an arrow shown on the motor fan cowl.
If the rotation direction of the drive motor is incorrect, open the isolating switch and reverse
two incoming electric lines.
Incorrect rotation direction of the drive motor may cause damage to the compressor.
3. Check also the rotation direction of the fan motor. Rotation arrows, visible through the
grating in the roof, are provided on the plate below the fan to indicate the correct rotation
direction of the fan motor.
If the rotation direction of the fan motor is incorrect, open the isolating switch and reverse
two incoming electric connections at the terminals of circuit breaker (Q15).
4. Start and run the compressor for a few minutes. Check that the compressor operates
normally.
5. Check that the outlet temperature doesn’t rise too much after start-up. The unit will
shutdown when the outlet temperature is 65°C (149°F) above the inlet temperature.
5.2 Before starting
Procedure
1. If the compressor has not run for the past 6 months, it is strongly recommended to improve
the lubrication of the compressor element before starting. See section Initial start .
