Setting The Pressure Switch - EINHELL 300/50 W Instrucciones De Manejo

2288-Air-Tech-Kompressoren
combined maintenance unit. Follow
the drawing for this.
The R 3/8" filter pressure reducer
and the R 3/8" combined mainten-
ance unit are basically fitted at the
boiler outlet. For this, unscrew the
quick coupling and attach the parts
with a R 3/8" shoulder nipple. The
quick coupling is fixed to the filter
pressure reducer or the combined
maintenance unnit.
All screw connections are sealed
with approx. 3-4 layers of sealing
tape before they are tightened up.
For professional use, you can also
run the Einhell AIRTECH Center on
your compressor.
For information on assembly and
connection to the compressor,
please read the instructions for the
AIRTECH Center.

Setting the pressure
switch

Using an 8 mm socket spanner,
adjust the differential pressure P on
screw 1.
The differential pressure and the
cut-out pressure are increased by
turning to the right. The differential
pressure is reduced by turning to
the left, and the cut-out pressure is
therefore lower.
Screw 2 is used to adjust the cut-in
and cut-out pressure P.
The cut-in and cut-out pressure is
increased by turning to the right.
The cut-in and cut-out pressure is
reduced by turning to the left.
Possible causes of
breakdown
which cause overloading of the
motor and thus activate the over-
load circuit breaker:
G mains power supply too high
G ambient temperature too high
and inadequate air supply
G faulty compressor valve or lea-
king nonreturn valve
G oil level at minimum, connecting
rod bearings stiff.
Switch on three-phase and AC
motors after leaving them to cool
down. Do not touch hot compo-
nents and pipes.
