conditioners, fans and heaters.
SOME PARTS HAVE PROTECTIVE COVERING (FILM) WHICH CAN BE REMOVED IF NEEDED.
Wash internal and external surfaces of the display case with a neutral
detergent and dry with a soft cloth.
3.4. OPERATION PROCEDURE
WARNING! After the display case was transported or stored at freezing
temperatures, keep it at room temperature (not less than 12°С) for 24h. The
connection of the cold device to the net may lead to compressor locking and
device failure.
Plug the power cord into the socket.
Install the key switches located on display case control panel into position
‘1’. After this, the indicator lamps of the switches should light up, the
display case lighting turn on and the luminous signs on the controller
display flash. In 5 seconds, the display shall show the current temperature in
the interior volume. The user can set the required temperature in the
interior volume on the controller display. Other controller parameters are set
at the manufacturing plant. To change them, it is necessary to call for the
refrigerating equipment operation and repair serviceman.
After starting the unit, and upon reaching the desired temperature, load the
display case with the products precooled down to the internal enclosure
temperature distributing them evenly on the trays. The height of product
display for demonstration must not be more than 150 mm and the distance to the
display case wall along the perimeter must not be less than 40 mm.
ATTENTION! The glass shelf must be used for displaying the products which do
not require cooling. Use the additional storage space for short-term storage
of goods which do not require cooling down to the refrigerated enclosure
temperature.
Shelf load must not exceed 3 kg per a meter of the distributed load.
Do not block the air conduits.
If the above requirements are not met, the air circulation is blocked, the
performance of the product deteriorates, which may lead to the damage of food
products.
The product compressor works in cycles turning off when the preset temperature
is reached and turning on when it increases by 3-4 ºС.
Thus, air temperature in certain spots of the refrigerated enclosure may rise
briefly and differ from controller readings, which does not constitute a
defect.
During its operation, the compressor regularly stops for the evaporator to
thaw. At the time of thawing, the temperature in the refrigerated enclosure
may rise, which does not constitute a defect.
Rainy or humid weather may cause condensation in the display case. This is not
a malfunction. In this case, wipe the display case with a soft cloth from time
to time.
The main signs of refrigerated display normal operation are the following:
– the temperature in the internal enclosure matches the preset one;
– the refrigerating unit is operating in cycles.
