Installation
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. Respect stacking loads according to Figure 1. 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 = 2
▪
Storage: n = 3

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.
For all models the suction connection plug must be left in place until the compressor is set into the
unit otherwise oil might spill out of the suction connection located low on the shell.
The compressor plugs must be removed as late as possible before brazing so that the air humidity
does not affect the oil characteristics.
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 as 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 for the grommet not to be 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. See Emerson spare parts software for reference.
