The environmentally friendly R290 is used as the refrigerant. R290 has no damaging influence on
the ozone layer (ODP), a negligible greenhouse effect (GWP) and is available worldwide. Because
of its efficient 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 flammability.
•
The unit is designed only for use with R-290 (propane) gas as the designated refrigerant.
•
The refrigerant loop is sealed. Only a qualified technician should attempt to service!
•
Do not discharge the refrigerant into the atmosphere.
•
R-290 (propane) is flammable and heavier than air.
•
It collects first 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 find
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 fire department to advise them that a propane leak has occurred.
•
Do not let any persons back into the room until the qualified service technician has arrived and that
technician advises that it is safe to return to the room.
•
No open flames, 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 flammable 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 flammable gas or
vapour being present while the work is being performed.
1.3 General work area
All maintenance staff and others working in the local area shall be instructed on the nature of work being
carried out. Work in confined spaces shall be avoided.The area around the workspace shall be sectioned
off. Ensure that the conditions within the area have been made safe by control of flammable material.
1.4 Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the
