Transportation and Handling
1. Special package box will be used for the equipment for delivery. Keep the equipment
erect during transportation and handling.
2. Please carefully check the package box after receiving the product to ensure that the
equipment is not damaged during transportation.
3. When removing the package box, carefully move away the wood plate in case of
scratch the equipment.
4. In case that the equipment tilts during the transportation and handling, the lubricant
inthecompressormayowintothecoolingloop.Therefore,inordertoensurethe
lubricantowsbacktothecompressor,itisnecessarytokeeptheequipmenterectfor
24 hours before it starts to work.
5. Do not throw away the package removed randomly. Please dispose as per relevant
local rules and regulations.
Installation and Operation
1. After the equipment is installed, please carefully clean parts in the cabinet .Then wipe
clean the bottom cover plate and shelf, put them on corresponding place, close the
cabinet door and get it connected to the power supply.
2. Turn on the lighting switch, check light on each shelf is normal.
3. The controller is delivered with default parameters. Do not alter the parameters
casually except for special need.
4. Whenrunningforthersttime,itshouldrunwithoutloadfor2hourstoensurethe
refrigeration system is working normally. Only when the temperature within the cabinet
is reduced within the indicated scope can the food be put into the cabinet.
5. Don’t put too much over-hot food in the cabinet to prevent instantaneous high load.
The food shall not block the air outlet and air inlet. Nor shall it be close to side glass.
Otherwise it will lead to condensation.
6. To save electricity, the heating wire switch is defaulted to be closed. If the environment
humidity is large, and there is condensation on the front glass, please open it for
defogging.
7. To keep the taste of the food, please have the equipment running 24 hours a day.
8. During the frosting process, the temperature of the cabinet may rise slightly. When the
frosting end, it will return to normal.
