The dryer doesn't drain the condensate
The dryer continuously drains condensate.
Water within the line.
If installed - HPS high pressure switch has
been activated.
If installed - LPS low pressure switch has been activated.
If installed - TS safety thermo switch has been activated.

NOTE: When the drain is in alarm condition, the diaphragm solenoid valve will open 7.5 sec every 4 min.
•
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.
•
Electronic drainer is not operating correctly (see paragraph 9.13).
•
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 the
electronic instrument is faulty - replace it
•
Electronic drainer is dirty (see paragraph 9.13).
•
The dryer doesn't start - see specific point.
•
If installed - Untreated air flows through the by-pass unit - close the by-pass.
•
The dryer doesn't drain the condensate - see specific point.
•
DewPoint too high - see specific point.
•
Check which of the following has caused the activation :
•
1. The ambient temperature is too high or the room aeration is insufficient - provide proper ventilation.
•
2. The condenser is dirty - clean it.
•
3. The condenser fan doesn't work - see specific point.
•
Reset the pressure switch pressing the button on the controller itself - verify the dryer for correct operation.
•
HPS pressure switch is faulty - contact a refrigeration engineer to replace it.
•
There is a leak in the refrigerating fluid circuit - contact a refrigeration engineer.
•
The pressure switch reset automatically when normal conditions are restored - check the proper operation
of the dryer.
•
Check which of the following has caused the activation :
•
1. Eccessive thermal load – restore the standard operating conditions.
•
2. The inlet air is too hot - restore the nominal conditions.
•
3. The ambient temperature is too high or the room aeration is insufficient - provide proper ventilation.
•
4. The condenser unit is dirty - clean it.
•
5. The fan doesn't work - see specific point.
•
6. The hot gas by-pass valve requires re-adjusting – contact a specialized technician to restore nominal
setting.
•
7. Refrigerant gas leak - contact a refrigeration engineer.
•
Reset the thermo switch by pressing the button on the thermo switch itself – verify the correct operation
of the dryer.
•
TS thermo switch is faulty - replace it.
•
Verify the electric wiring of T1 DewPoint probe.
•
The T1 DewPoint probe is faulty - replace it.
•
The electronic instrument is faulty - replace it.
•
ADS 10-100 - Verify the electric wiring of T2 fan control probe.
•
ADS 10-100 - The T2 fan control probe is faulty - replace it.
•
ADS 125-480 - Verify the electric wiring of resistance on terminal 1 and 2
•
The electronic instrument is faulty - replace it.
•
DewPoint too low - see specific point.
•
The T1 DewPoint probe is faulty - replace it.
•
The electronic instrument is faulty - replace it.
•
DewPoint too high - see specific point.
