OTHER TIPS(be applicable for R32 refrigerant)
WARNING(be applicable for R32 refrigerant)
Do not use means to acclerate the defrosting process or to clean,other than those
recommended by 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 the refrigerants may not contain the odour.
Appliance should be installed,operated and stored in a room with a floor area larger
than 4m
2
.
Compliance with national gas regulations shall be observed.
Keep ventilation openings clear of obstruction.
The appliance shall be stored so as to prevent mechanical damage from occuring.
A warning that the appliance should be stored in a well ventilated area where the
room size coresponds to the room area as specified for operation.
Any person who is involved with working on or breaking into the 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 person competent in the
use of flammable refrigerants.
1.Transport of equipment containing flammable refrigerants
See transport regulations
2.Marking of equipment using sighs
See local regulations
3.Disposal of equipment using flammable refrigerants
See national regulations.
4.Storage of equipment/appliances
The storage of equipment should be in accordance with the manufacturer's instructions.
5.Storage of packed(unsold) equipment
Storage package protection should be constructed such that mechanical damage to the
equipment inside the package will not cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to be stored together will be
determined by local regulations.
6.Information on servicing
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 conducting work on the
system.
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.
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.
4)Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to 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.non-sparking adequately sealed or intrinsically safe.
5)Presence of fire extinguisher
If any hot work is to be conducted on the refrigerantion equipment or any associted
parts,appropriate fire extinguishing equipment shall be available to hand,Have a dry
powder or CO2 fire extinguisher adjacent to the charging area.
6)No ignition sources
No person carrying our work in relation to a refrigeration system which involves
exposing any pipe work 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 possibly be released to the surrounding
space.Prior to 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.
