Danger!
Make certain there is no one under the
suspended load during transport with
the crane!
Position the screw compressor package on the
transport vehicle such that it is prevented from tilting
and falling. Load securing is preferably carried out by
lashing to the specified points. The pipes and equip-
ment of the screw compressor package must not be
entered. Components must be secured against
vibrations. The competent staff member or the com-
pany itself is responsible for ensuring safety during
transport.
Warning!
Screw compressor packages must be
adequately protected from external
influences during transport.
Transport packaging (optional): foil
The foil may only be removed before erecting the
screw compressor package at the intended installa-
tion location in the machine room. Up until this point
in time, the foil serves to protect the screw compres-
sor package against external influences.

When the screw compressor packages are deliv-
ered, check for possible transport damage and report
any damage to the manufacturer in writing.
The storage area of screw compressor units shall be
roofed, plain and paved and secured against access
of unauthorized persons. Place the screw compres-
sor package onto timber planks and have it protected
from jerks or impacts.
Warning!
Screw compressor packages must be
adequately protected from external
influences (humidity, frost, extreme
heat) during storage. This usually con-
cerns lengthy standing times outdoors
before installation and start-up of the
refrigeration plant. The manufacturer
recommends the use of plastic sheet-
ing to cover the whole product.
The venting slits of the electric motors
must always be covered!
Storage temperature: 5°C ... 40°C
The composition of the paint on the screw compres-
sor package is designed for installation in the
machine room (inside installation). Contact with
water (including water spray) must be avoided.
Warning!
The screw compressor package is fil-
led with dry gas (e.g. nitrogen) before
delivery which prevents any change of
the properties of any already filled
operating medium (e.h. refrigerating
machine oil). Check the gas filling
once a week and recharge to the
specified overpressure if required.
Turn the shaft of the compressor at least every four
weeks (approx. 10 revolutions).
The transport packing (foil if present), that needs to
be opened for turning the compressor shaft and for
checking the gas filling, must be closed again after
carrying out the activities in order to ensure protec-
tion against external influences. The packing (foil if
present) must be replaced as needed and for lengthy
storage times.
