Page 20: Maintenance
8. MAINTENANCE The heat pump water heater is highly automatic equipment, which is checked periodically over its unit state in application. If the unit can be maintained effectively for a long time, the operation reliability and lifespan of the unit will be greatly enhanced. 1 The water filter installed outside the unit should be cleaned periodically to ensure a clean water supply in the system in case the unit may be damaged due to the blocked dirty water filter.
