also Annex B to compare lab and store conditions.
Maintenance
The freezer should be cleaned regularly. When cleaning, turn off the power,
take out the foods in the cabinet, clean the inside using water or a little neutral
detergent.
Do not use boiling water, acid, chemical diluents, petrol and oil, or dirt-
removing powder.
Dry it after cleaning.
Use light soap water when cleaning the door seal, apply a little of talcum
powder on it after natural drying to extend its service life.
Use soft cloth with water or a little detergent to clean the out surface. Note,
keeping the power supply and lower part of connect wires away from water to
avoid electricity leakage.
Except common breakdowns, those who are not service technician should
not take apart and repair the freezer on their own so as to avoid worsening
the trouble Unauthorized repair of electrical part such as compressor,
temperature controller is forbidden.
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

6
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 relation 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. All 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 place, 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 ares shall be checked with an
appropriate refrigerant detector prior to and during work, to ensure the
technician is aware of potentially toxic or flammable 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.

7
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.

- The refrigerator should be placed on flat and stable ground. Choose a flat,
hard inflammable block if you need to block up. You also can rotate the
stainless steel leg clockwise or counterclockwise to increase or decrease the
height of the refrigerator.
2．Keep far away from hot source
- Refrigerator should be kept away from hot source and not under direct
sunshine in case of effecting refrigeration ability.
3．Ventilation Condition
- Should be put in the aeration place, at least 3 cm space behind and
around the refrigerator
