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 4. 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 4: 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 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.
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.
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 51 mm into the suction tube as it
might damage the suction screen and motor.
3.1.3 Installation location
Scroll compressors are capable of operating correctly with compressor ambient humidity between
30% and 95%. For correct operation the compressor ambient air temperatures have to be between
-40°C and 60°C and the compressor PS and TS have to be respected at all times during operation
and at a standstill.
Ensure the compressors are installed on a solid level base. For single compressor application, the
compressor tilt angle during operation should not be more than 15° to allow adequate lubrication.
For multiple compressor parallel configurations, the compressors must be positioned completely
vertically on a totally horizontal surface or rail.
3.1.4 Mounting parts
A kit of vibration absorber grommets can be ordered 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
