1.3 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 CO
2
and approved refrigeration
oils must be used.
WARNING
CO
2
refrigerant! Danger of suffocation!
Never release significant volumes
of CO
2
or the entire contents of the system into closed rooms. In case of closed
room, if possible, keep the room well ventilated and/or install a CO
2
detection
device. CO
2
is odourless and colourless, so it cannot be perceived directly in
case of emission.
WARNING
Earth leakage current! Danger of electric shock!
This product can cause
both AC and DC earth leakage current. To protect against both kinds of leakage
current it is recommended to use an AC/DC sensitive RCD
type B or B+
on
the power supply side.
WARNING
High surface temperature! Burning!
Do not touch the compressor or piping
until they have cooled down. Ensure that other materials in the area of the
compressor do not come into contact with it. Mark and secure 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 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).
