Chapter 9 - 12
The compressor may only be transported unpressurised.
Before transport, compressed air in the pressure tank and
pressure hoses must be released, and condensate water

must drained off
9. Installation guidelines
Unpack the compressor and check carefully to ensure that it is in
faultless condition. Assemble the support legs. The compressor may
only be installed and operated in a dry, well-ventilated and low-dust
location, at an ambient temperature of +5°C and +40°C. The motor fan
ensures that the power unit is force-cooled effectively. However, for this
to happen, the air must be able to flow in and out without obstructions.
If this is not the case, a separate ventilation system must be installed

.
The compressor must not touch any other objects to prevent heat
build-up. The compressor must be installed in such a way that it is
easily accessible for operation and maintenance, and placed on a
robust and level floor. If the compressor is fitted in a mounting bracket,
then the mounting bracket should not be secured to the ground. It is
recommended to attach four vibration dampers.
10. Instrument unit
The compressor is fitted with an instrument unit as standard consisting
of the following:

pressure reducer with condensate separator
7.2

The flexible delivery hose must be pushed onto a pipe connection and
secured against slippage using hose clips.
The flexible delivery hose connecting the permanently
i
installed compressed air pipe and the compressor
prevents the transfer of vibrations and noise.

11. Electrical connections
Connections to the mains supply may only be made by a qualified
electrician. It must be ensured that the electrical wiring and the mains
voltage conform with the data indicated on the type plate. A tolerance
of +/- 5% is permissible. Earthing must always be used for safety
purposes.
12. Preparations before first use
Before using the compressor for the first time, it must be ensured that
all the fastenings securing the compressor for transportation have
been removed. Ensure that the compressed air lines are connected
correctly. The compressor must be connected to the mains supply in
the proper manner. Switch on the compressor at the pressure switch
by rotating the switch to position "1".
Safety valve
The safety valve is set at 10 bar. Upon first use of the
compressor, the safety valve must be checked.
The safety valve may not be used to vent the pressure tank,
as this may impair the function of the safety valve!
Adjusting the pressure switch
8
The pressure switch is factory-set. The power unit switches itself
on when the tank pressure is at 5 bar, and off at 7 bar. If necessary, the
working pressure of the compressor may be altered at the pressure
switch.
These tasks may only be carried out by authorised
technicians. The protective cover of the pressure switch
must be removed and the unit turned on when adjusting
the pressur switch.
If problems develop with the cut-in and cut-out pressure, refer to the
following:
ƒ Screws A: Minimum pressure adjustment (cut-in) – both of them
have to be regulated at the same level. Note that to regulate Max
pressure, it is enough to regulate screws A (min. pressure) because
the differential pressure is fixed.
ƒ Screw B: Differential min-max pressure adjustment (cut-out) –
