13. SWITCHING THE COMPRESSOR ON
(Fig.7)
Compressor switch on at pressure switch by turning the shift (3) to position
“I” , compressor starts to work and pressurize air to air chamber. At the
compressed air consumption the pressure in the air nozzle drops to the
closing pressure, the compressor in put into operation and the air nozzle is
filled with compressed air. After reaching the cutoff pressure the
compressor turns off automatically. After releasing – pressure decreasing in
the air nozzle and reaching the closing pressure, the compressor is again
put into operation. Check this value at manometer (5). Setting of switching
or switching-off pressure can vary within the range of i
±
10%. Air pressure
in air chamber must not exceed maximal permitted operation pressure.
It is not allowed to tamper and change pressure limits of pressure switch at compressor
Pressure switch (2) was adjusted by manufacturer

15. MAINTENANCE
Repair works that exceed the framework of common maintenance can be performed only
by qualified expert or customer service of manufacturer.
Use only spare parts and accessories prescribed by manufacturer.
Prior every work at maintenance or repair, switch off the compressor and disconnect it
from mains (pull out mains plug).
In order to find out correct work of compressor, it is necessary, in certain intervals (Chapter 14) to perform
the following activities:
15.1. Condensate drain down
Compressors (Fig.8)
In the case of regular operation, it is recommended to release condensate
from pressure tank 1 x week (at high air humidity 1 x day).
•
Switch off the compressor from mains and reduce air pressure in the
device to pressure of max. 1 bar, for example by releasing air via
connected device.
•
Canalize hose with sludging valve to vessel prepared in advance. By
opening the release valve (1) release condensate from tank.
•
Wait till condensate is fully delivered from pressure tank.
•
Again close release valve (1).
