The fan of the condenser
doesn't work (Air-
Cooled).
DewPoint too high.
DewPoint too low.
Excessive pressure drop
within the dryer.
The dryer doesn't drain
the condensate.
The dryer continuously
drains condensate.
Water within the line.
Verify the electric wiring.
Where installed- P pressure switch is faulty - replace it.
V
DMC15- The DMC15 electronic controller is faulty - replace it.
If the fan still doesn't work, replace it.
The dryer doesn't start - see specific point.
The T1 DewPoint probe doesn't correctly detect the temperature - ensure
the sensor is pushed into the bottom of copper tube immersion well.
The refrigerating compressor doesn't work - see specific point.
The ambient temperature is too high or the room aeration is insufficient -
provide proper ventilation (Air-Cooled).
The inlet air is too hot - restore the nominal conditions.
The inlet air pressure is too low - restore the nominal conditions.
The inlet air flow rate is higher than the rate of the dryer - reduce the flow
rate - restore the normal conditions.
The condenser is dirty - clean it (Air-Cooled).
The condenser fan doesn't work - see specific point (Air-Cooled).
The cooling water is too hot - restore the nominal condition (Water-Cooled).
The cooling water flow is insufficient - restore the nominal condition (Water-
Cooled).
The dryer doesn't drain the condensate - see specific point.
The hot gas by-pass valve is out of setting - contact a refrigeration engineer
to restore the nominal setting.
There is a leak in the refrigerating fluid circuit - contact a refrigeration
engineer.
DMC15- The fan is always ON - the
is glowing continuously - see specific point
DMC14- The fan is always ON - P
Cooled).
Ambient temperature is too low - restore de nominal condition.
The hot gas by-pass valve is out of setting - contact a refrigeration engineer
to restore the nominal setting.
The dryer doesn't drain the condensate - see specific point.
The DewPoint is too low - the condensate is frost and blocks the air - see
specific point.
Check for throttling the flexible connection hoses.
The condensate drain service valve is closed - open it.
The condensate drain 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 condensate drain solenoid valve burned out - replace it.
The (DMC15 or DMC14) electronic controller is faulty - replace it.
The DewPoint is too low - the condensate is frozen - see specific point.
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.
The dryer doesn't start - see specific point.
Where 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.
