OPERATION
IN CASE OF EMERGENCY, DISCONNECT THE COMPRESSOR FROM THE MAINS
(PULL OUT THE MAINS PLUG).
THE COMPRESSOR AGGREGATE HAS HOT SURFACES.
BURNS OR FIRE MAY RESULT IF CONTACT IS MADE.
During prolonged operation of the compressor, the temperature in the cabinet
may increase to over 40°C. At this point the cooling fan automatically switches
on. After cooling the space to under 32°C, the ventilator switches off.
Automatic start: when pressure in the pressure tank decreases below the switch-
on pressure, the compressor automatically switches on. The compressor
automatically switches off when pressure in the air tank reaches the switch-off
pressure.
The working pressure settings for the pressure switch set by the manufacturer cannot be
changed. Compressor operation at a working pressure below the switch-on pressure indicates
high air consumption (see the chapter Malfunctions)
Required drying performance can only be achieved when following the defined
operating conditions!
Drying performance will decline and the achieved dew point will drop if the dryer
is operated at any pressure below the minimum working pressure!
WHEN THE DRYER IS OPERATED AT AMBIENT TEMPERATURE THAT IS HIGHER
THAN MAXIMUM OPERATING TEMPERATURE, THE DRYER MAY BE DAMAGED!
