equipment with reference to the
Installation Manual.
Read the precautions in this manual
carefully before operating the unit.
• 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
without continuously operating ignition
sources (for example: open flames, an
operating gas appliance or an operating
electric heater.)
• Do not pierce or burn.
• Be aware that refrigerants may not contain
an odour.
• Keep any required ventilation openings clear
of obstruction
• Auxiliary devices which may be a potential
ignition source shall not be installed in the
duct work. Examples of such potential
ignition sources are hot surfaces with a
temperature exceeding X°C and electric
switching devices.
• Only auxiliary devices approved by the
appliance manufacturer or declared suitable
with the refrigerant shall be installed in
connecting ductwork.
• The appliance shall be stored so as to
prevent mechanical damage from occurring.
The manufacturer should specify other
potential continuously operating sources
known to cause ignition of the refrigerant
used.
• Compliance with national gas regulations
shall be observed
• Refrigerant tubing shall be protected or
enclosed to avoid damage.
• The installation of pipe-work shall be kept to
a minimum
• A brazed, welded, or mechanical connection
shall be made before opening the valves to
permit refrigerant to flow between the
refrigerating system parts.
• Any person who is involved with working on
or breaking into a refrigerant circuit should
hold a current valid certificate from an
industry-accredited assessment authority,
which authorises their competence to handle
refrigerants safely in accordance with an
industry recognised assessment
specification.
• Servicing shall only be performed as
recommended by the equipment
manufacturer.
Maintenance and repair requiring the
assistance of other skilled personnel shall be
carried out under the supervision of the
person competent in the use of flammable
refrigerants.
• Periodic cleaning of the dust of salt particles
stuck on the heat exchanger by using water.
• Dismantling the unit, treatment of the
refrigerant oil and eventual parts should be
done in accrodance with local and national
standards.
• 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
conducting work on the system.
• 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.
