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, including cigarette smoking, should be kept sufficiently far
away from the site of installation, repairing, removing and disposal,during which refrigerant can
possibly be released 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 displayed.
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 flammable
atmospheres. Ensure that the leak detection equipment being used is suitable for use with all
applicable refrigerants, i.e., no spark, 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 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 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.
Operation of the Temperature control knob
△
The temperature in the cabinet can be controlled with the temperature control knob.
△
The knob should be kept upright normally to adjust the temperature. FREEZING MAX/HI is
the strongest cooling position and is suitable for fast freezing. Do not keep the knob at this
point for long periods of time.
Food storage
△
There must be space between the foods stored in the cabinet, between the foods and the
inner surface of the cabinet, so as to keep good ventilation of cold air and freeze evenly.
Do not put in any bottled or canned beverages with freezing point above the temperature
in the cabinet when it is below zero.
△
For foods that should be moisture-free or lose water easily, wrap them up with airtight food
bags or plastic films before putting in the cabinet to avoid smell-mixing and reduce frosting.
△
Storage of volatile and combustible gases, liquids as strong alkalis, strong acids, petrol, etc.
is forbidden.
△
This equipment is designed and intended exclusively for the storage of ice cream and other
frozen desserts.
Maintenance
△
The freezer should be cleaned regularly. When cleaning, turn off the power, take out
the foods in the cabinet and 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.
