5 Electrical connection
Before connecting the air dryer, the following items must be checked:
Does the mains voltage coincide with the voltage of the appliance?
Adequate fusing of socket and supply system?
Has the required residual-current-operated circuitbreaker (r.c.c.b) been installed in case of
swimming baths?
If a cable drum is used: has it been unwound completely?
Is the appliance connector suitable for the building socket?
Is the socket provided with a perfect grounding?
Attention!
Before putting the air dryer into operation, the technical data of the appliance should be
compared to the conditions prevailing in the room of installation!
6 Operation
6.1 Putting into operation
Attention!
Before putting the air dryer into operation, the instruction manual should be studied carefully.
Thus, damages by a false or inappropriate operation as well as by inadequate environmental
conditions can be avoided.
For using the air dryer, please proceed as follows:
After having been transported, the air dryer should rest for abt. 15 min. During this period
of time, the oil distributed inside the refrigerating system and frothed during transport will
return into the compressor. We recommend this procedure since it extends the service life
of the compressor.
Put the plug into the socket.
Check whether the bucket is inside the equipment resp. whether the drain hose has been
fastened and laid appropriately.
Switch on the appliance at the hygrostat.
Set the required humidity value at the hygrostat (please refer in this respect to 'Hygrostat
Control').
If the existing humidity is higher than the set value, the air dryer will start to operate.
If the existing humidity is lower than the set value, the air dryer will not start to operate.
6.2 Hygrostatregelung
The air dryers of the DH-series dispose of a hygrostat for setting the required humidity value.
The hygrostat is placed at the upper side of the unit. It makes that the air dryer cuts in as soon
as the ambient humidity exceeds the preset value. If the humidity value falls below the set
value, the hygrostat will switch off the appliance.
The following operating modes can be set by means of the hygrostat:
The marker of the knob points at position "O" the device is switched off. It is not drying.
The marker of the knob points at the field with one drop: The device is working. When
achieving a humidity of approx. 70% r.h. (relative humidity) the unit will switch off.
The marker of the knob is between the field with one drop and the field with two
drops: The device is working. When achieving a humidity of approx. 50% r.h. (relative
humidity) the unit switch off .
The marker of the knob shows onto the field with three drops: The device is working.
When achieving a humidity of approx. eliminate 40% r.h (relative humidity) the unit will
switch off.
