The dryer continuously
drains condensate.
SULLIMAX drainer is dirty (see SULLIMAX MANUAL)
Water within the line.
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.
Where installed - The
HPS high-pressure
switch has been
activated.
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.
The HPS pressure switch is faulty - contact a refrigeration engineer to replace it.
Where installed - The
LPS low-pressure switch
has been activated.
There is a leak in the refrigerating fluid circuit - contact a refrigeration engineer.
The pressure switch restores automatically when normal conditions are restored - check the proper operation
of the dryer.
Where installed - The
TS safety thermo-switch
has been activated.
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. There is a leak in the refrigerating fluid circuit - contact a refrigeration engineer.
Reset the thermo-switch by pressing the button on the thermo-switch itself – verify the correct operation of
the dryer.
The TS thermo-switch is faulty - replace it.
DMC14 - The LED of the
instrument is on or
flashes to indicate alarm
situations.
The LED flashes because the DewPoint is too high – see specific point.
The LED flashes because the DewPoint is too low - see specific point.
The LED flashes because the probe is faulty or interrupted, the instrument displays the message “PF” (Probe
Failure) – replace the probe.
The dryer doesn’t drain
the condensate.
The condensate drain service valve is closed - open it.
Verify the electric wiring.
The DewPoint is too low - the condensate is frozen - see specific point.
SULLIMAX drainer is not operating correctly (see SULLIMAX MANUAL)
