1.3 General
instructions
WARNING
System breakdown! Personnel 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! Personnel injuries!
Only approved refrigerant and refrigerating oils
must be used.
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 get in touch 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.
IMPORTANT
Transit damage! Compressor malfunction! Use original packaging. Avoid collisions and
tilting.
Only qualified personnel should install and intervene on COPELAND condensing units.
The contractor, responsible for the installation of the unit, should ensure 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 in the cylinder
head. When operating with air the so-called diesel effect may occur, i.e. the air sucked in
is mixed with oil gas and can explode due to the high temperature in the cylinder head,
and thereby destroy the compressor.
