OPERATION
NP-DK50 2V-A-4_10-2022-AD 40 10/2022
OPERATION
THE EQUIPMENT MAY ONLY BE OPERATED BY THE TRAINED STAFF!
Risk of burn or fire.
During compressor operation, the pump parts may heat to temperatures
dangerous for contact with persons or materials.
Warning – compressor is controlled automatically.
Automatic start-up. When pressure in the pressure tank drops to switch-on
pressure, the compressor automatically switches on. The compressor
automatically switches off, when pressure in the air tank reaches the switch-off
pressure.
Hazard of damage to pneumatic components.
Working pressures of the pressure switch set by the manufacturer must not be
changed. If the compressor operates at higher working pressure than the switch-
on pressure, it means that the air consumption is too high (see Chapter
Malfunctions)
Hazard of damage to dryer.
When the dryer is operated at ambient temperature that is higher than maximum
operating temperature stated in Technical data, the dryer can be damaged.
Required drying performance can only be achieved when the defined operating
conditions are followed.
Drying performance decreases and the achieved dew point drops if the dryer is
operated at any pressure below the minimum working pressure.
During longer operation of the compressor, the temperature in the surrounding
of the compressor increases above 40 °C and the cooling fan switches on
automatically. After cooling the space below 32 °C, the fan switches off.
