General information and safety instructions
General information
These maintenance and operating instructions contain information
necessary for the perfect and troublefree operation of your screw-
type compressor. Thoroughly read these instructions before
commission, because damage caused by improper handling is not
covered by our warranty.
F
Regulations, laws and important information
This compressor has been built in accordance with the EG machine
regulations 98/37/EG. All our specifications about the noise emission
are in accordance with EN ISO 3746 and the EG machine regulation,
chapter I, section 1.5.8 etc., this manual in according to section 1.7.4,
etc.
The machine has been built in accordance with the general technical
rules. Operation can still mean danger for user or others, or even
result in damage to the machine and other values.
The machine may only be used to produce compressed air. Other use
is strictly not allowed.
Neither the manufacturer nor the supplier take the responsibility for
damage caused by other use as to produce compressed air.

1. Safety instructions
1.1 Safety instructions for personnel and
compressor function
F
The compressor system must only be erected, operated and
maintained by trained
p
and from the user authorized personnel.
Each authorized person must have read and understood the complete
manual. Unauthorized conversions and modifications which influence
the safety of the compressor are not allowed.
F
In any case all work to be carried out on the compressor is to be
done in cut-off and pressure-relieved condition. The compressor system
is to be protected against unauthorized reconnection.
Attention - caution! The sound absorbing bonnet of the
compressor is part of the protection against accidental
contact and may only be opened upon completion of the
above mentioned measures.
1.2 Safety measures to be taken before
commissioning
F
The allowable compressor room temperature is : +5 °C to +40
°C. The electric connection must only be carried out by an authorized
specialist. Check the correctness of current, voltage and frequency.
The correct supply line is to be dimensioned and protected in
compliance with the electrical data mentioned on page 13.
1.3 Safety measures to be taken during
commissioning
F
Check the maximum oil level at the lower edge of the oil filler
neck (11.1). Fill about 0.2 l. oil into the oil prefill plug of the suction
unit (06). Check the correct direction of rotation (see arrow on the
electric motor). Switch on (and immediately off) for only a very short
(max. 0.5 sec.) time.
1.4 Safety measures for maintenance and
operation
F
All work is to be carried out with the machine at standstill and
pressure-relieved. Switch off the power supply and protect it against
reconnection. Close the shut-off valve to the compressed-air piping
system (or compressed-air receiver tank). Damaging condensate water
in the oil tank (11) should only be checked out in cold condition and
must be drained. Check the oil level only with the compressor in warm
condition.
Attention: all cooler nozzles are to be counterbacked with a
sufficient key; mind not to overturn the cooler connections.
Caution! The compressor system oil tank (11) can be under
residual pressure! Hot and oily compressed air penetrates
when the safety valve (12) is operated! Do not discharge
the compressed-air condensate into the sewage system (refer
to section 3.4).
