When the compressor is connected to the mains and to the distribution line, push on the
black button (1) to start it. In case of a three-phase compressor, check the direction of
rotation marked on the motor (3) and on the grid (10). Check that the ventilator (4) of the
air/air exchanger works properly.
As soon as the manometer (5) reads 8 bar*, the compressor stops and will start again at
6 bar. At every stop a slight whistling warns that the silica-gel is being regenerated. Fans
(6 and 7), installed on the same shaft, turn simultaneously with the motor. As a rule, the
hottest points of a properly running and pausing compressor get temperatures ranging
from 60 to 85 °C.
In one, two or three cylinder compressors, in case of any anomaly, press the red knob
on yellow background (11) placed on the door (9) (this door should be kept closed when
the compressor is running) or the red button (2), (if the door had been left unintentionally
open). For tandem compressors or Blok-Jet, turn the red on yellow door-locking switch
(12) placed on the control panel. For special plants, clinics, hospitals and factories, cus-
tomized manuals are issued.
Ordinary maintenance
(drw. page 70)
To be entrusted to the surgery staff, purposely trained
Before approaching the compressor, disconnect it from the mains and ascertain that
nobody can connect it again without the maintenance operator knowing it.
If the compressor is installed in a dusty spot or where it can aspirate solid particles, as dust,
sand, dry leaves or similar, the head fi lters should be cleaned and replaced very often.
If it is installed in a clean room, it will be enough to clean the fi lters (A) every three
months and replace them every six months. If a Balston sterilising fi lter is installed (S),
we recommend to sterilise it in autoclave at 135 °C at least every six months, for max
20 times. We recommend to wear disposable gloves and to put the fi lter immediately into
the autoclave.
A Balston fi lter lasts one-year max. Replacement cartridges are available; follow the
directions given with the fi lter and mark the operation on the report sheet.
Check the ventilator running every week, as the compressor cannot work for long without
adequate ventilation.
Tap (8), placed under the air tank, must be opened at regular intervals: if moisture is
noticed, call for an engineer. Every week, loose manually the condensation draining screw
placed under the tank: air coming out must be dry; otherwise call for an engineer.
Note that the air-drying system cannot work properly with environment temperature
above + 35 °C.
The compressor should not start if no compressed air is used: differently, check for any
leak in the system or in the compressed-air-using appliances.
Charging time is about 45/55 sec. and the pausing for the regeneration of the silica gel
and for cooling time is about one third of the charging one.
A careful watch lengthens the life of the appliance: when it gets noisy or vibrates, some-
thing has loosened or worn out – call for the engineer.
Experience and the volume of the surgery work will give indications to every operator
about increasing or decreasing the frequency of the mentioned operation in comparison
with our advice.
Always fi ll in the "Ordinary maintenance" report-sheet.
* Excepted one-cylinder compressor running from 5.5 to 7.5 bar.
