WARNING
High pressure!
Injury to skin and eyes possible!
Be careful when
opening connections on a pressurized item.
3.1 Compressor handling
3.1.1 Transport and storage
WARNING
Risk of collapse! Personal injuries!
Move compressors only with
appropriate mechanical or handling equipment according to weight. Keep in
the upright position. Stack pallets on top of each other when not exceeding
300 kg. Do not stack single boxes on top of each other. Keep the packaging
dry at all times.

3.1.2 Positioning and securing
IMPORTANT
Handling damage! Compressor malfunction!
Only use the lifting eyes
whenever the compressor requires positioning. If the compressor has two
lifting tabs, both must be used for lifting. Using discharge or suction
connections for lifting may cause damage or leaks.
For models ZBD58K* to ZBD114K* and ZFD41K5E,
because oil might spill out of the suction
connection located low on the shell, the suction connection plug must be left in place until the
compressor is set into the unit. If possible, the compressor should be kept vertical during
handling. The discharge connection plug should be removed first before pulling the suction
connection plug to allow the dry air pressure inside the compressor to escape. Pulling the plugs
in this sequence prevents oil mist from coating the suction tube making brazing difficult. The
copper-coated steel suction tube should be cleaned before brazing. No object, eg, a swaging
tool should be inserted deeper than 51 mm into the suction tube or it might damage the suction
screen and motor.
3.1.3 Installation location
Ensure the compressors are installed on a solid level base.
3.1.4 Mounting parts
Four vibration absorber grommets are supplied with each compressor. They dampen the start-up
surge of the compressor and minimise sound and vibration transmission to the compressor base
during operation. The metal sleeve inside is a guide designed to hold the grommet in place. It is
not designed as a load-bearing member, and application of excessive torque to the bolts can
crush the sleeve. Its inner diameter is approximately 8.5 mm to fit, eg, an M8 screw. The
mounting torque should be 13 ± 1 Nm. It is critically important that the grommet is not
compressed.
If the compressors are mounted in tandem or used in parallel, then the hard mountings (bolt M9
5/16”) are recommended. The mounting torque should be 27 ± 1 Nm. It is possible to deliver
these hard mounting parts as a kit, or on request to deliver the compressor with these parts
instead of the rubber grommets.
