General instructions
WARNING
System breakdown! Personal injuries! Never install a system in the field
and leave it unattended when it has no charge, a holding charge, or with the
service valves closed without electrically locking out the system.
System breakdown! Personal injuries! Only approved refrigerants and
refrigeration oils must be used.
WARNING
High shell temperature! Burning! Do not touch the compressor until it has
cooled down. Ensure that other materials in the area of the compressor do
not come into contact with it. Lock and mark accessible sections.
CAUTION
Overheating! Bearing damage! Do not operate compressors without
refrigerant charge or without being connected to the system.
CAUTION
Contact with POE! Material damage! POE lubricant must be handled
carefully and the proper protective equipment (gloves, eye protection, etc.)
must be used at all times. POE must not come into contact with any surface
or material that it might damage, including without limitation, certain
polymers, eg, PVC/CPVC and polycarbonate.
IMPORTANT
Transit damage! Compressor and/or unit malfunction! Use original
packaging. Avoid collisions and tilting.
The contractor is responsible for the installation of the unit and should ensure that there is sufficient
liquid sub-cooling in the line to the expansion valve(s) to avoid "flash-gas" in the liquid line.
It is of vital importance that the discharge stop valve has been fully opened before the compressor
is started. If the discharge stop valve is closed or partly closed an unacceptable pressure with
accordingly high temperatures may develop on the discharge outlet in the compressor. When
operating with air the so-called diesel effect may occur, ie, the air sucked in is mixed with oil gas
and can explode due to the high temperature, and thereby destroy the compressor.
