• The environmentally friendly R290 is used as the refrigerant. R290 has no damaging inuence on
the ozone layer (ODP), a negligible greenhouse eect (GWP) and is available worldwide. Because
of its ecient energy properties, R290 is highly suitable as a coolant for this application. Special
precautions must be taken into consideration due to the coolant’s high ammability.
• The unit is designed only for use with R-290 (propane) gas as the designated refrigerant.
• The refrigerant loop is sealed. Only a qualied technician should attempt to service!
• Do not discharge the refrigerant into the atmosphere.
• R-290 (propane) is ammable and heavier than air.
• It collects rst in low areas but can be circulated by the fans.
• If propane gas is present or even suspected, do not allow untrained personnel to attempt to nd
the cause.
• The propane gas used in the unit has no odor.
• The lack of smell does not indicate a lack of escaped gas.
• If a leak is detected, immediately evacuate all persons from the store, ventilate the room and contact
the local re department to advise them that a propane leak has occurred.
• Do not let any persons back into the room until the qualied service technician has arrived and that
technician advises that it is safe to return to the room.
• No open ames, cigarettes or other possible sources of ignition should be used inside or in the
vicinity of the units.
• Component parts are designed for propane and non-incentive and non-sparking. Component parts
shall only be replaced with identical repair parts
INSTRUCTIONS FOR REPAIRING APPLIANCES CONTAINING R290
1. GENERAL INSTRUCTIONS
1.1 Checks to the area
Prior to beginning work on systems containing ammable refrigerants, safety checks are necessary
to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the following
precautions shall be complied with prior to con-ducting work on the system.
1.2 Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the risk of a ammable gas or
vapour being present while the work is being performed.
