Switching The Compressor On; Compressor Shut-Down - EKOM DUO Benutzerhandbuch

SWITCHING THE COMPRESSOR ON

(Fig. 13)
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 dryer that removes moisture from the compressed
air.
Compressor with a condensation and filtration unit (KJF) - during usage by the device, the
compressed air passes through the KJF unit, where the air is cooled, filtered and condensed liquid
is captured and automatically drained into a collecting bottle.

COMPRESSOR SHUT-DOWN

(Fig. 13)
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. Then open the drain valve (Fig. 14)
to decrease the pressure in the air tank to zero.
