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 horizontal position. Respect stacking loads according to
Figure 10
. 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 10: Maximum stacking loads for transport and storage
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 horizontal 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, eg, a swaging tool should be inserted deeper than 35 mm into the suction tube as it might
damage the suction screen and other internal parts.
3.1.3 Installation location
Ensure that the compressor and drive are installed on a solid level base.
3.2 Compressor mounting parts
The compressors are designed to be mounted on vibration absorber grommets. The grommets
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 suit, eg, an M8 screw. The
mounting torque should be 13 ± 1 Nm. It is critically important that the grommet is not compressed.
