Both the water tank and the water pump should be kept clean and free of any accumulation of foreign objects. When deposits do occur (more foreign matter or clay buildup), the tank should be thoroughly cleaned. If the machine has been shut down for more than a day, the water tank should be cleaned once before restarting to ensure the quality of ice making. The specific cleaning steps are as follows:
1. Turn off and turn off the main power.
2. Drain all the ice making machine
water in the water tank through the drain valve, clean the dirt in the water tank with detergent and a long-handled brush, and then rinse with clean water several times until there is no dirt.
3. After the float valve stops water supply, inject new water to the liquid level, and then it can be opened for use.
Evaporation tube cleaning
In the case of long-term use, a small amount of dirt may accumulate on the inner wall of the evaporation tube, which needs to be cleaned regularly. The frequency of cleaning depends on the water quality. In areas with hard water (where there is too much lime in the local water), cleaning every 3-6 months is required, while in areas with normal or "soft" water, twice a year is sufficient. The specific cleaning steps are as follows:
1. Drain the water in the tank first. Add clean water until the water tank is full for nine minutes, then close the water supply valve. Add 2.1 L pure citric acid and mix with water.
2. Turn off the refrigeration compressor, close the liquid circuit stop valve; turn on the water pump (in the case of no refrigeration) to run the cycle for about 2-3 hours. (Press "Start Cleaning" to clean; press "Stop Cleaning" to stop cleaning.)
3. After the sewage is discharged, inject new water and circulate for about 30 minutes. After washing off any remaining detergent, release a second run of water. Cycle the cleaning more than two times to ensure that the cleaning agent has been washed away.
4. Open the water supply valve, restore the refrigeration system, and restore the machine to normal operation. When the float valve stops water supply, inject new water to the liquid level, and then it can be opened for use.
Water-cooled condenser cleaning
During the operation of the condenser, the cooling water will produce scale in the tube, which will affect the heat exchange effect. It should be cleaned frequently to improve cooling efficiency. The frequency of cleaning depends on the water quality. In areas with extremely hard water, wash every three months, while in areas with normal or "soft" water, only twice a year. The cooling system includes a cooling water tower and a water-cooled condenser to make the machine run smoothly and ensure the service life of the machine. The cooling tower should also be cleaned in time to ensure the efficiency of ice making.
The specific cleaning steps are as follows:
1. Shut down, first use a brush to clean the cooling water tower.
2. If the cooling tower is higher than the condenser, the cooling tower water should be drained first or the inlet and outlet valves of the condenser and cooling tower should be closed.
3. Open the drain valve under the end cover of the condenser to drain the water in the condenser.
4. Remove the end caps on both ends of the condenser. Use a dedicated condenser brush to clean each copper tube back and forth, then rinse with water a few times until clean.
5. After cleaning, reinstall the end cap and connect the pipes.
