1.4.3 Cold units with remote CO
2
(R744) refrigerant
WARNING
Remote CO
2
refrigerant is environmentally friendly but under high pressure. It is non-
toxic with zero Ozone Depletion Potential (ODP) and very low Global Warming
Potential (GWP).
Read this manual carefully and follow all precautions described herein.
SAFETY
Wear eye protection when working on the refrigeration system.
•
Do not tamper with the system.
•
The system must be installed and maintained by suitably qualified persons only.
•
Fixate the unit to the floor.
•
The ventilation openings of the cladding of the unit (including accessories) must not be
blocked or covered. Ensure that the air circulation remain unobstructed.
•
A pressure relief device shall be installed in the high-pressure side of the refrigeration system
between the motor-compressor and the gas cooler. There shall be no shut off devices or
other components except piping between the motor-compressor and the pressure relief
device that could introduce a pressure drop.
•
The pressure relief device shall be mounted so that any refrigerant released from the system
during its operation cannot cause harm to the user of the appliance. The aperture shall be
located so that it is unlikely to be obstructed in normal use.
•
The installed pressure relief device shall have no provisions for setting by the end user.
•
The pressure setting of the installed pressure relief device shall be no higher than the design
pressure of the high-pressure side.
1.4.4 Moving (when applicable)
When moving the unit:
•
Before moving the unit, first switch off the mains voltage by pulling the plug from the wall
socket.
•
Remove pans containing a liquid product from the unit.
•
Always keep the unit in upright position.
•
Make sure that the wheels can move freely, so they never touch the power lead.
1.4.5 Outdoor use restrictions
WARNING
To avoid short-circuiting, the units may not be used outdoors or in a rainy or very moist
environment.
