Pressure gauge
Q1/H1
On/off switch with lamp
P1
Hour meter
Gd
Dew point gauge
Procedure
1. Close the manual condensate drain valve(s) if present.
2. Open the air outlet valve (AV).
3. Switch on the voltage. Lamp (H1) alights.
4. Rotate switch (Q1) to position I.
5. The motor starts and stops automatically depending on the air pressure.
6. On compressors equipped with a refrigerant dryer, the dew point of the refrigerant
dryer will be reached after a few minutes.
During operation
Procedure
1. Check the pressure gauge (Gp) on the control panel to check the pressure setting.
2. On compressors with a built-in refrigerant dryer, check also the temperature gauge
(Gd) on the control panel to check the dew point.
Check that condensate is discharged regularly by the automatic drain of the dryer.
The amount of condensate depends on the operating conditions of the unit and
the humidity of the air.
Open the manual drain valve from time to time to remove eventual impurities (see
also section Preventive Maintenance schedule).
3. On receiver mounted compressors, open the manual drain valve of the air receiver
regularly to remove the water (specially in case of compressors without dryer). See
also section Preventive Maintenance schedule).
NOTICE!
The dew point will deviate from nominal when the nominal conditions are exceeded.
If the dew point remains too high or unstable, consult section Problem solving.
