Installation and maintenance
1. Please place the chiller in a clean, well-ventilated place with good heat dissipation (it is recommended to place it outdoors with a sunshade, and there is no large heat source in the space within 2 meters of the equipment)
2. Please clean the condenser regularly. It is best to use no less than 0.8Mpade gas (usually nitrogen) or a soft brush to clean the dust on the condenser fins (blow perpendicular to the fins to prevent the fins from being blown down) In order to avoid the poor heat dissipation of the condenser during the long-term operation of the equipment, the high-pressure protection of the chiller will be caused, and the compressor will not start and affect customer use.
3. Please clean the water tank regularly and change the water frequently.
4. In order to avoid abnormal flow of the chiller, please change the water filter frequently,
5. Pay attention to the monthly maintenance of the chiller, thoroughly clean the internal pipeline of the equipment once a month, and carefully check whether there are oil stains in the refrigeration pipeline. If there are oil stains, the cooling effect of the equipment is not good, please check by professionals maintain.
