WARNING
High pressure! Injury to skin and eyes possible! Be careful when opening
connections on a pressurized item.
3.1 Compressor and drive handling
WARNING
Static electricity! Personal injuries! Personnel handling the drives in a
manufacturing plant environment should guard against static electricity by
using the appropriate equipment - antistatic wrist straps and mats.
3.1.1 Compressor 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. Respect stacking loads according to Figure 12. Check
the tilting stability and if needed take action to ensure the stability of the
stacked loads. Keep the packaging dry at all times.
Respect the maximum number of identical packages which may be stacked on one
another, where "n" is the limiting number:
▪ Transport: n = 1
▪ Storage: n = 2
Figure 12: Maximum stacking loads for transport and storage
The compressor tilt angle should not be more than 30° during transport and handling. This will
prevent oil from exiting through the suction stub. A tilt angle of maximum 45° is allowed for a very
short time. Tilting the compressor more than 45° might affect its lubrication at start-up.
3.1.2 Compressor positioning and securing
IMPORTANT
Handling damage! Compressor malfunction! Only use the lifting eyes
whenever the compressor requires positioning. Using discharge or suction
connections for lifting may cause damage or leaks.
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.
The compressor plugs must be removed as late as possible before brazing so that the air humidity
does not affect the oil characteristics.
As 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.
No object, e.g., a swaging tool should be inserted deeper than 51 mm into the suction tube as it might
damage the suction screen and motor.
3.1.3 Installation location
Ensure the compressors are installed on a solid level base. For single compressor applications, the
compressor tilt angle during operation should not exceed 15° to allow adequate lubrication. For
multiple compressor parallel configurations, the compressors must be positioned completely
vertically on a totally horizontal surface or rail.
