WARNINGWARNING
Only use this unit in a well-ventilated area and
ensure unit's airflow inlet and outlet would not be
impeded by obstructions. Do not use this unit in
the following locations:
Locations with mineral oil.
Locations with saline atmospheres, such as
seaside locations.
Locations with sulphurous atmospheres, such
as near natural hot springs.
Where high voltage electricity is present, such
as in certain industrial locations.
On vehicles or vessels, such as trucks or ferry
boats.
Where exposure to oily or very humid air may
occur, such as kitchens.
In proximity to sources of electromagnetic
radiation, such as high-frequency transmitters or
other high strength radiation devices.
WARNINGWARNING
Do not use means to accelerate the defrosting
process or to clean, other than those
recommended by the manufacturer.
The appliance shall be stored in a room that
does not have continuously operating ignition
sources (for example: open flames, an operating
gas appliance or an operating electric heater).
Do not pierce or burn the unit.
Be aware that refrigerants may not contain an
odour.
If refrigerant gas leaks during installation,
ventilate the area immediately.
Comply with national gas regulations.
WARNING
This appliance is not intended for use by people
(including children) with reduced physical,
sensory or mental capabilities, or people who
lack experience and knowledge, unless they are
supervised or have been given instructions
concerning the use of the appliance by a person
responsible for their safety.
Children should be supervised to ensure that
they do not play with the appliance.
Any person who is involved with working on or
opening a refrigerant circuit should hold a current
valid certificate from an industry-accredited
assessment authority, which authorizes their
competence to handle refrigerants safely in
accordance with an industry recognized
assessment credential.
Servicing shall only be performed performed by
licensed and qualified HVAC service personnel.
Maintenance and repair requiring the assistance
of other skilled personnel shall be carried out
under the supervision of a person competent in
the use of flammable refrigerants.
Prior to beginning work on systems containing
flammable refrigerants, safety checks are
necessary to minimize the risk of ignition.
WARNING
When repairing the refrigerating system, comply
with the following precautions prior to conducting
work on the system:
– The work shall be undertaken according to
controlled procedures to minimize the risk of the
presence of flammable gases or vapors during
the work.
– 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 shall be checked with an appropriate
refrigerant detector prior to and during work, to
ensure the technician is aware of potentially
toxic or flammable environment. Ensure that the
leak detection equipment being used is suitable
for use with all applicable refrigerants, i.e.
non-sparking, adequately sealed or intrinsically
safe.
– If any brazing is to be conducted on the
refrigerating equipment or any associated parts,
appropriate fire extinguishing equipment shall be
available and easily accessible. Have a dry
powder or CO2 fire extinguisher adjacent to the
charging area.
– When carrying out work in relation to a
refrigerating system that involves exposing any
pipe work, no sources of ignition shall be used 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,
repair, or removal and disposal of the unit, during
which refrigerant can possibly be released into
the surrounding space. Prior to beginning work,
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 clearly displayed.
Ensure that the area is in the open or that it is
adequately ventilated before opening 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
surroundings.
Where electrical components are being
changed, they shall be fit according to their
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 actual refrigerant charge 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.
– Equipment marking must remain visible and
legible. Markings and signs that are illegible
shall be corrected.
