3. Erection

3.1 General information

F

 The screw-type compressor is mounted on a solid frame ready

for operation. Only a level solid floor is necessary for erection.

The screw-type compressor is to be placed in a cool, dry and dust-free
room with proper ventilation and a room temperature b 5
°C and + 40 °C.

When the room temperature might  fall below + 5°C, an additional
compressor heating is to be installed into the compressor system oil
tank (11) or the room is to be heated.

When the room conditions are inconvenient, it may be necessary, owing
to excess heating, to dissipate the hot exhaust air by means of exhaust
shafts or cooling fans for a sufficient supply of fresh air.

The place of installation shall be well accessible. Refer for assembly
dimensions and required quantities of fresh air to the technical data
on page 13.

3.2  Pneumatic connection

F

 Screw-type compressors will be delivered complete and ready

for connection. The connection from the compressed-air outlet (10)
to the piping system must only take place through a tape-sealed fle-
xible hose, so that no forces can be transmitted between the
compressed air piping system and the compressor unit.

The pipe end of the piping system is to be thoroughly secured.

In order to avoid that the condensate collected in the compressed-air
recooler (09) is fed into the piping system or into the downstream
receiver tank, a condensate trap with automatic separator is to be
installed in the discharge line, if possible in direct vicinity of the
compressed-air outlet (10). Refer page 13 for the outlet dimensions.

A non-return valve between piping system or receiver tank and
machine is not required, because this device is already installed in the
screw-type compressor. It is, however, recommended to install a shut-
off valve in the compressed-air line, so that the compressor is able to
be disconnected from the piping system, if necessary.

3.3 Electric connection

F

 Electric connection is only to be carried out by skilled electricians.

Check if current, voltage and frequency is according to the nameplate
data. The cross section of the feed line and the fuses are to be
dimensioned in accordance with the local prescriptions ! Refer to the
data on page 13.

3.4 Condensate trap

F

 The condensate collected in the condensate trap (refer 3.2) is

oily and must not be fed into the sewage system without further treat
(Our after-sales service would be pleased to assist you in the selection
of sufficient air-oil separation systems
