The dryer does not
drain the condensate.
The condensate drain service valve is closed - open it.
Condensate strainer is clogged – remove and clean it.
The drain solenoid valve is jammed – remove and clean it.
Verify the electric wiring.
The coil of the drain solenoid valve is failed – replace it.
Electronic instrument is faulty – repace it.
The DewPoint is too low - the condensate is frost and blocks the air - see specific point.
Inlet compressed air pressure is too low and condensate is not drained – restore nominal conditions.
The SULLIMAX condensate drain does not work properly (see SULLIMAX MANUAL).
Failure during the
condensate
discharge.
The drain solenoid valve is jammed – remove and clean it.
Try to remove the electric connector on the solenoid valve - if drain stops verify the electric wiring or

Please read the separate SULLIMAX installation and operating instructions.
The dryer does not start – see the corresponding point.
If installed - untreated air flows through the bypass unit – close the bypass.
The dryer does not drain condensate – see the corresponding point.
Dew point too high – see the corresponding point.
If installed: the HPS
high-pressure switch
has triggered.
Check which of the following reasons is responsible for the triggering:
1. The ambient temperature is too high or the room ventilation insufficient – ensure
sufficient ventilation.
2. The condenser is dirty – please clean it.
3. The condenser fan does not work – see the corresponding point.
Reset the pressure switch by pressing the button on the controller itself – check the proper
functioning of the dryer.
The HPS pressure switch is defective – contact a SULLAIR service technician for the replacement.
If installed:
the LPS low-pressure
switch was triggered.
There is a leak in the refrigeration cycle – please contact a SULLAIR service technician.
The pressure switch is automatically reset as soon as the normal conditions are re-established –
check the dryer for proper functioning.
