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
get in touch with it. Lock and mark accessible sections.
WARNING
Uncovered rotating parts! No safety grids on the condenser fans!
Personal injuries! Never start the condensing unit or run the fans with no air
ducts connected or without protective end-grids on the air outlets.
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.
The contractor is responsible for the installation of the unit and should check the following points:
▪
Sufficient liquid sub-cooling in the line to the expansion valve(s) to avoid "flash-gas" in the
liquid line;
▪
Sufficient amount of oil in the compressor (in case of long piping additional oil must be
charged).
