First, please do not cut off the total power supply during the heating period. Cutting off the total power supply will cause the unit to freeze, and if it is not used for a short period of time, the temperature can be turned down to maintain low temperature operation.
Second, if the unit is not used for a long time, all the water in the unit should be drained and the total power supply should be turned off. If the power outage lasts for more than 4 hours, contact the manufacturer in time to consult whether the water in the system needs to be drained to prevent the machine from being frozen.
Third, during the heating period, it is necessary to ensure that the ventilation of the unit is smooth, and there should be no obstructions around it, and the debris on the unit should be cleared in time. If there is no ventilation, the phenomenon of icing and frosting may occur, resulting in low heating efficiency or shutdown of the unit.
Fourth, after the end of the heating period, it is recommended that users let the machine run for about 5-10 minutes every month, for confirming that there is no problem with the unit and also extending its service life.
When the heater is hot on the top and cool on the bottom, the filter on the pipe must be cleaned in time. During the use of the unit, users should clean the pipe filters regularly. At the beginning of the heating period, the number of cleaning times should be judged according to the water quality of their own pipelines, and it is recommended to clean them once in 20-30 days after operation.
