4.2 Installing the compressor

Every compact semi-hermetic screw compressor is a
motor-compressor unit. Therefore, it is only necessary
to install the whole unit correctly and to connect the
electrical system and the pipelines.
Install/mount the compressor horizontally. Take suit-
able measures if the compressor is operated under ex-
treme conditions (e.g. aggressive atmosphere, low out-
side temperatures, etc.). Consultation with BITZER is
recommended.
With regard to marine applications, defined diagonal
mounting on the longitudinal axis of the ship can be ne-
cessary. Detailed system design recommendations
upon request.

4.3 Connecting the pipelines

WARNING
The compressor is under pressure!
Serious injuries are possible.
Depressurize the compressor!
Wear safety goggles!
NOTICE
!
!
Potential chemical reactions due to air penetra-
tion!
Proceed swiftly and keep shut-off valves closed
until evacuation.

4.2.1

Vibration damper

Solid mounting is possible. To reduce structure-borne
noise however, it is recommended to use vibration
dampers that have been especially tuned-in to the com-
pressors (option).
NOTICE
!
!
Do not mount the compressor solidly on the
heat exchanger!
Risk of damage to the heat exchanger (fatigue
fractures).
Mounting the vibration dampers
The screws should only be tightened until first deforma-
tions signs of the upper rubber disc are visible.
4.3.1

Pipe connections

The pipe connections are suitable for pipes in all com-
mon dimensions in millimetres and inches. Brazed con-
nections have stepped diameters. The pipe will im-
merge more or less depending on its dimensions. If ne-
cessary, the bushing may even be cut at the end with
the largest diameter.
4.3.2

Shut-off valves

CAUTION
Depending on the operation mode, the shut-off
valves may become very cold or very hot.
Risk of burning or frostbite!
Wear suitable protective equipment!
