15. SWITCHING ON THE COMPRESSOR
Start the compressor (without a cabinet) at the pressure switch (1) by turning the switch (2) to
position “I.” This starts the compressor and fills the tank to the switching off pressure, which then
shuts off the compressor.
Start the compressor (with a cabinet) at the switch (4) on the front side of the cabinet, the indicator
will turn green. This starts the compressor and fills the tank to the switching off pressure, which then
shuts off the compressor.
The compressor operates in automatic mode, switched on and off by the pressure switch, depending
on compressed air consumption.
Check the values of switch-on and switch-off pressure using the pressure gauge (3). Tolerance of
± 10 % is acceptable. Pressure in the air tank must not exceed the allowed operating pressure.

Risk of damage to pneumatic parts.
The pressure switch (1) was set up by the manufacturer and any other changes
to it settings may be performed only by a qualified technician trained by the
manufacturer.
16. SWITCHING OFF THE COMPRESSOR

Switching off the compressor due to service or any other reason shall be performed using the
pressure switch (1) by turning the switch (2) to position „0“ (Fig. 20) and pulling out the mains
plug from the socket. This disconnects the compressor from the mains supply.

Vent the pressure in the air tank to zero by opening the drain valve.

Open the venting plug (Fig. 25) to vent the pressure in the dryer chambers.
17. AD DRYER OPERATING MODES:
“RUN” mode
The dryer is in “RUN” mode when the control signal from the compressor is active. The cooler fans
are activated and the chambers are cyclically switched by the solenoid valves based on the following
time diagram T. This is the chamber switching period, and dT represents the pressure balancing
time in the chambers prior to switching.
