OPERATION

THE EQUIPMENT MAY ONLY BE OPERATED BY THE TRAINED STAFF!
IN CASE OF EMERGENCY, DISCONNECT THE COMPRESSOR FROM THE MAINS
(PULL OUT THE MAINS PLUG).
THE AIR PUMP 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!

16. COMMISSIONING

 Make sure all transport stabilizers were removed.
 Check that all pressurized air line connections are secure.
 Check to ensure power is connected correctly to the compressor.
 Check to ensure the switch is in the "I" position. Turn the switch (2) to the "I" position if found in
the "0" position. (Fig. 13)
 For cabinet-mounted compressors, turn the switch (4) on the front side of the cabinet to the "I"
position; a green indicator indicates the device is in operation. (Fig. 13)
 Check the connection of the cabinet connector to the compressor. (Fig. 12)
 Check the connection of the the cabinet pressure gauge hose to the compressor pneumatic
block. (Fig.3and8)
