THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY
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 odour. 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.
Be aware that refrigerants do not have any odour.
FAILURE TO ABIDE BY THIS WARNING COULD RESULT IN AN EXPLOSION,
DEATH, INJURY AND PROPERTY DAMAGE.

SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when servicing an
appliance with R290.
Checks to the area
Before beginning work on systems containing flammable refrigerants, safety checks
are necessary to ensure that the risk of ignition is minimized. For repair to the
refrigerating system, the following precautions shall be complied with before
conducting work on the system.
Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk of
flammable gas or vapour being present while the work is being performed.
General work area
All maintenance staff and others working in the local area shall be instructed on the
nature of the 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.
Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector before and during
work, to ensure the technician is aware of potentially flammable atmospheres. Ensure
that the leak detection equipment being used is suitable for use with flammable
refrigerants, i.e. no sparking, adequately sealed or intrinsically safe.
Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated
parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry
powder or CO2fire extinguisher adjacent to the charging area.
No ignition sources
No person carrying out work in relation to a refrigeration system that involves exposing
any pipework that contains or has contained flammable refrigerant shall use any
sources of ignition in such a manner that it may lead to the risk of fire or explosion. All
possible ignition sources, including cigarette smoking, should be kept sufficiently far
away from the site of installation, repairing, removing and disposal, during which
flammable refrigerant can be released to the surrounding space. Before work taking
place, the area around the equipment is to be surveyed to make sure that there are no
flammable hazards or ignition risks. “No Smoking” signs shall be displayed.

Phone: [phone] - Mon-Fri 8:30am –4.30pm Page 18
Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking
into the system or conducting any hot work. A degree of ventilation shall continue
during the period that the work is carried out. The ventilation should safely disperse
any released refrigerant and preferably expel it externally into the atmosphere.
Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and
to the correct specification. At all times the manufacturer’s maintenance and service
guidelines shall be followed. If in doubt consult the manufacturer’s technical
department for assistance.
The following checks shall be applied to installations using flammable refrigerants:
The charge size is in accordance with the room size within which the refrigerant
containing parts are installed;
The ventilation machinery and outlets are operating adequately and are not
obstructed;
If an indirect refrigerating circuit is being used, the secondary circuit shall be
checked for the presence of refrigerant;
Marking the equipment continues to be visible and legible. Markings and signs that
are illegible shall be corrected;
refrigeration pipe or components are installed in a position where they are unlikely
to be exposed to any substance which may corrode refrigerant containing
components unless the components are constructed of materials that are
inherently resistant to being corroded or are suitably protected against being so
corroded.
Checks to electrical devices
Repair and maintenance of electrical components shall include initial safety checks and
component inspection procedures. If a fault exists that could compromise the safety,
then no electrical supply shall be connected to the circuit until it is satisfactorily dealt
with. If the fault cannot be corrected immediately but it is necessary to continue
operation, an adequate temporary solution shall be used. This shall be reported to the
owner of the equipment so all parties are advised.
Initial safety checks shall include:
those capacitors are discharged: this shall be done in a safe manner to avoid the
possibility of sparking;
that there no live electrical components and wiring are exposed while charging,
recovering or purging the system;
there is continuity of earth bonding.
WARNING! Install the unit in rooms that exceed 10 m².
WARNING! Do not install the unit in a place where inflammable gas may leak.

Cleaning up refrigerant
General Measures:
1. Gas/vapour is heavier than air and may accumulate in confined spaces,
particularly at or below ground level.
2. Eliminate every possible source of ignition.
3. Use appropriate personal protection equipment (PPE).
4. Evacuate unnecessary personnel, isolate, and ventilate the area.
5. Do not get in eyes, on the skin, or on clothing. Do not breathe vapours or gas.
6. Prevent entry to sewers and public waters.
7. Stop the source of the release, if safe to do so. Consider the use of water spray to
disperse vapours.
8. Isolate the area until gas has dispersed. Ventilate and gas test area before
entering. Contact competent authorities after a spill.
Disposal
WARNING!!! Releasing refrigerant into the atmosphere is strictly forbidden!
Do not dispose of electrical appliances as unsorted municipal waste, use separate
collection facilities. Contact your local government for information regarding the
collection systems available. If electrical appliances are disposed of in landfills or
dumps, hazardous substances can leak into the groundwater and get into the food
chain, damaging your health and well-being.
