How to use and maintain the snowflake ice machine

1. For the location of the ice machine:

(1) This machine should be placed in a place where air is circulated and cleaned around. This machine should not be placed in the open air. It should not be exposed to direct sunlight and rain, and it should not be close to the heat source.

(2) Machine use ambient temperature requirements: not lower than 5 ° C and not higher than 40 ° C.

(3) Machine space requirements: When the machine is used, there must be enough space around the machine to facilitate the heat release of the machine. Special attention should be paid to the back of the machine, which cannot be less than 250mm.

2. Installation of ice machine:

(1) Please connect the water source that meets the local drinking water standard; if necessary, connect the filter to improve the drinking standard of water; the water supply system must meet the following conditions: a. The water temperature is at least 2 °C, and the maximum is not more than 32 °C; b. Water pressure minimum 137kp, maximum 551kpa

(2) In terms of safety of use: the power supply must be the same as indicated on the machine nameplate; all lines must comply with national standards; must be reliably grounded, and the grounding wire must meet electrical standards.

3. Cleaning knowledge of ice machine:

(1) The inner and outer surfaces of the freezer need to be cleaned with a mild cleaning agent and warm water. During the cleaning process, ensure the surface finish of the cabinet. Do not use abrasive-containing cleaning agents and acid cleaning agents to prevent wear on the cabinet.

(2) When cleaning the water tray and the evaporator, it can be washed with low-pressure water, and the remaining water leaks out from the drain pipe. During the cleaning process, large debris is prevented from blocking the water outlet.

(3) When cleaning the glass surface (the glass on the freezer and the curved glass on the hot cabinet), first return the glass surface temperature to room temperature, then clean it with a soft cleaning agent. Do not use hot water to clean the cold glass surface to prevent it from happening. Explosion; for the surface of the mirror, avoid damage to the coating. Dry the residual water on the mirror surface after wiping.

(4) Cleaning steps of the freezer

1 Remove the goods and sundries from the cabinet and store them in the cold storage.

2 Cut off the power in the cabinet and the unit before cleaning.

3 Hang up the fan assembly, and hook the fan hook to the rear air duct. After washing, return to the original position to avoid damage to other cooling pipes and wire plugs.

4 Clean all surfaces with a cleaning agent, do not rinse the inside of the cabinet with high-pressure water

The water in the 5 cabinets will be drained out of the cabinet in time, and then the cabinet will be cooled and then energized. Avoid direct contact of the fan motor with water.

In addition, regular inspections should be carried out on the cleaning machine. If problems are found, they should be dealt with in time to avoid further expansion.

The surrounding environment of the unit should be cleaned regularly. Do not pile up debris and flammable materials nearby. If the unit is placed indoors, the unit should be ventilated. When the condenser is cleaned, first turn off the main machine, brush the dust in the direction of the heat exchange sheet, or use a vacuum cleaner or high-pressure air to blow off the dirt between the sleeves. When washing with water, avoid splashing on the motor or other electrical parts.

In the process of using the ice machine, sometimes the temperature will not fall, what should I do? We can do this like this:

1. First check if the temperature of the adjustment is correct. If the temperature is not low, the temperature will not fall automatically. It may be the cause of the ambient temperature. If it is summer, suddenly the temperature is adjusted too much, then it may not cool down at once, and a process is needed.

2. The throttle valve is improperly adjusted or blocked, and the refrigerant flow rate is too large or too small. If the throttle valve is improperly conditioned or blocked, it will directly affect the flow of refrigerant into the transpiration unit. When the opening degree of the throttle valve is too large, the refrigerant flow rate is too large, the transpiration pressure and the transpiration temperature also increase, and the warehouse temperature reduction speed will be slowed down.

3. Look at the water tank behind the refrigerator. Do you have any defrosting water that does not flow directly into the sink? Therefore, there is water in the refrigerator. Try to raise the front of the refrigerator slightly. Try it. Ensure that the defrosting water flows smoothly into the sink.

4, the compressor power is low, the cooling capacity can not be satisfied with the warehouse load demand. Because the inferior compressor works for a long time, the sealing function will be reduced accordingly, the compressor's gas transmission coefficient will also be reduced, and the cooling capacity will be reduced.

5. There is more air or frozen oil in the transpiration machine, and the heat transfer effect is reduced. Once the inner and outer parts of the transpiration heat transfer tube are attached with more refrigeration oil, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of ​​the transpiration machine is reduced, and the heat transfer is performed. The power will also be significantly reduced, and the warehouse temperature will slow down.

6. The surface of the ice machine transpiration machine is too thick or excessively dusty, and the heat transfer effect is reduced. Another important reason for the slower temperature reduction in the tea shop ice machine is the low heat transfer power of the transpiration machine, which is mainly due to the excessive thickness or excessive dust on the outer surface of the transpiration machine.

7. The cold cabinet has a large loss of cooling due to poor heat insulation or sealing function. The poor heat insulation function is due to insufficient thickness of the insulation layer of pipes, warehouse insulation walls, etc., and poor heat insulation and heat preservation.
