Maintenance
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.
If any hot work is to be conducted on the refrigerating equipment or any associated
parts, appropriate fire extinguishing equipment shall be available on hand. A dry
chemical or CO2 fire extinguisher should be adjacent to the charging area.
Notice: 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 authorizes their competence to
handle refrigerants safely in accordance with an industry recognized assessment
specification.
Notice: 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.
No person carrying out work in rel ation to a REFRIGERATING SYSTEM which
involves exposing any pipe work shall use any sources of ignition in such a manner
that it may lead to the risk of fire or explosion. AIl possible ignition sources, incl
luding cigarette smoking, should be kept sufficiently far away from the site of
installation, repairing, removing and disposal,during which refrigerant can possibly
be rel leased to the surrounding space. Prior to work taking pl ace, the area around
the equipment shall be surveyed to make sure that there are no flammable
hazards or ignition risks.“No Smoking" signs shall be displ layed.
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 toxic or fl lammable atmospheres. Ensure that the leak
detection equipment being used is suitable for use with all applicable refrigerants,
i.e., nonsparking, adequately sealed, or intrinsically safe.
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 ventil lation shall
continue during the period that the work is carried out. The ventilation should safely
disperse any rel leased refrigerant and preferably expel it externally into the
atmosphere.
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.
Detection of flammable refrigerants: Under no circumstances shall potential
sources of ignition be used in the searching for or detection of refrigerant leaks. A
halide torch (or any other detector using a naked flame) shall not be used.
Defrosting
Defrost for better freezing efficiency when the frost film in the cabinet is 4-5mm
thick.
When defrosting, turn off the power, take out the frozen foods, open the door for
warming and melting. Use soft cloth to absorb water and clean it up.

Do not use sharp metal tools such as steel brush to clean the frost film when
defrosting so as to avoid evaporator damage.

there’s contact between
pipes. Separate them.
The following are not faults:
When the freezer is working or after stopping for a while, the refrigerant in
the pipes is cycling and gives out＂running water＂sounds.
The surface temperature of the compressor may be up 70℃~80℃when it
is working.
The back side of step cooler gives out heat.
In rainy season, the outer surface of the cabinet may have dew, which
makes no defects on normal use. Just dry it with a piece of cloth.
