】 【Weak current College of air-source heat pump water heater maintenance.

<br> 1. air-source heat pump water heater is the high degree of automation devices, use regular unit status check, if the unit for long-term efficient maintenance, crew of operational reliability and service life are unpredictable. <br> < .br> 2. machines installed water filters should be regularly cleaned to ensure clean water quality within the system to avoid blocking unit for filter dirty and caused damage to the host. <br> <br> 3. users in the use and maintenance of heat .pump unit attention: all security protection devices are set up at the factory, not to remove or adjust. <br> <br> 4. always check the air-source heat pump water heater unit's power supply and electrical wiring are secure, electrical components .if there is an exception, if any action should be timely repair and replacement. <br> <br> 5. always check water system water, water safety valve, liquid-level controller and the exhaust system is working, so that the air enters .the system reduces the amount of water circulation, thus affecting the heating unit and the unit operation reliability. <br> <br> 6. check the water pump, water valve is working, water pipes and water pipes leak connectors. <br> < .br> 7. the unit should be kept clean and dry around, well ventilated. Annual clean air side heat exchangers to maintain good heat effect. <br> <br> 8. always check unit of each part of the work, check the machines .pipes fittings and valves for oil-filled, ensure that no disclosure unit refrigerant. <br> <br> 9. do not pile of debris around the unit to avoid clogging outlet, the unit should be kept clean and dry around, well ventilated. .<br> <br> 10. If the downtime is long, the unit of water discharged in the pipeline, and cut off the power, set a good shield. Then at run time, the post before the system thoroughly inspected. <br> .<br> 11. when the actual air-source heat pump water heater outlet temperature and units control panel display values do not correspond, please check whether the contact temperature sensor device. <br> <br> 12. the units fails, the user .could not be resolved in a timely manner, please call to the Service Department and inform the failure code, so that timely sent for repair. <br> <br> 13. host condenser cleaning, we recommend that every two years using 50 ℃ - .60 ℃, the concentration of heat for 15% of phosphoric cleaning condenser, start the host comes with 3 hours of circulating pump cleaning, final cleaning 3 times with tap water. For cleaning. No corrosive cleaning fluid to clean the condenser. <br> .<br> 14. water tank in use for a period of time (usually 3 months, depending on local water quality) need cleaning. <br> <br> <br> <br>.
