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, eg, antistatic wrist straps and mats.
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. Respect stacking loads according to
Figure 11 . 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 11: Maximum stacking loads for transport and storage
The compressor tilt angle should not exceed 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.
NOTE: The compressor is pre-charged with dry air to avoid any moisture contamination.
3.1.2 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.
No object, eg, a swaging tool should be inserted deeper than 45 mm into the suction tube as it might
damage the suction screen and motor. Also, no object should be inserted deeper than 30 mm into
the discharge tube to avoid damage to the check valve.
3.1.3 Installation location
Ensure the compressor and drive 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.
