17. SWITCHING THE COMPRESSOR ON

(Fig. 12): Start the compressor at the pressure switch (1) by turning the switch (2) to the "I"
position. Check the position of the breaker switch to ensure it is in the "I" position. If not, turn the
breaker switch (4) to the "I" position. Turn on the switch (5) on the front of the cabinet, the indicator
will turn green.The compressor begins running, the air tank is filled, and the switching pressure and
pressure switch turn the compressor off. The compressor operates in automatic mode, switched on
and off by the pressure switch, depending on compressed air consumption.
Check the values of the switch-on and switch-off pressure using the pressure gauge (3). A
tolerance of 10% is acceptable. The pressure in the air tank must not exceed the permitted
operating pressure.

Adjustments to the pressure range on the compressor's pressure switch are
prohibited. The pressure switch (1) was set up by the manufacturer and only a
qualified technician trained by the manufacturer may make any changes to its
settings.
Compressor with a suction unit – when first started and placed into service, the compressor fills
the air tank until the switching pressure and the pressure switch turn off the compressor. The
compressor operates in automatic mode, switched on and off by the pressure switch, depending
on compressed air usage.
The suction aggregate is controlled from the dental set. Suction unit operation is indicated by the
white indicator on the front of the cabinet.
Compressor with dryer – the compressor operates in the same manner as above, only the
compressed air passes through a cooler and a dryerthat removes moisture from the compressed
air.

18. COMPRESSOR SHUT-DOWN

(Fig.12)
Compressor shut-down for either service or any other reason is performed at the pressure switch
(1) by turning the alternation switch (2) to the "0" position and pulling the mains plug from the
socket. This disconnects the compressor from power supply. Vent the pressure in the air tank to
zero by opening the drain valve. (Fig. 13)
