Maintenance, troubleshooting, spare parts and dismantling
DRS30-DRS125 27
Prior to carrying out maintenance works at the dryer, switch it off and wait for at least 30 minutes.
Caution!
Hot surfaces!
During operation, several components can reach surface temperatures of more than 140°F (60°C). There
is the risk of burns.
All components concerned are installed inside of the closed housing. The housing must only be opened
by certified skilled personnel.
Some components can reach high temperatures during operation. Avoid any contact until the system or
the component has cooled down.
SYMPTOM POSSIBLE CAUSE - SUGGESTED ACTION
◆
The dryer doesn't
start.

Verify that the system is powered.

Verify the electric wiring.
◆
The compressor
doesn
’t work.

Activation of the compressor internal thermal protection - wait for 30 minutes, then retry.

Verify the electric wiring.

If installed - Replace the internal thermal protection and/or the start-up relay and/or the start-
up capacitor and/or the working capacitor.

If the compressor still doesn’t work, replace it.
◆
Condenser
’s fan
doesn
’t work.

Verify the electric wiring.

The DMC35 electronic instrument is faulty
– replace it.

There is a leak in the refrigerant circuit - contact a refrigeration engineer.

If the fan still doesn't work, replace it.
◆
DewPoint too
high.

The dryer doesn't start - see specific point.

The DewPoint
probe BT1 doesn’t correctly detect the temperature - ensure the sensor is pushed
into the bottom of probe well.

The Compressor doesn’t work - see specific point.

The ambient temperature is too high or the room aeration is insufficient - provide proper ventilation.

The inlet air is too hot - restore nominal conditions.

The inlet air pressure is too low - restore nominal conditions.

The inlet air flow rate is higher than the rate of the dryer - reduce the flow rate - restore nominal
conditions.

The condenser is dirty - clean it.

The condenser fan doesn’t work - see specific point.

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 nominal
setting.

There is a leak in the refrigerant circuit - contact a refrigeration engineer.
◆
Dew Point too low

The fan is always ON - the yellow LED of DMC35 electronic instrument is flashing -
see specific point.

Ambient temperature is too low - restore nominal conditions.

The hot gas by-pass valve is out of setting - contact a refrigeration engineer to restore
nominal setting.
