1. Product safety statement 1. This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
2. Functionings & principles A low-pressure liquid refrigerant is vaporized in the heat pump's evaporator and passed into the compressor. As the pressure of the refrigerant increases, so does its temperature. The heated refrigerant runs through a condenser coil within the storage tank, transferring heat to the water stored there.

3. Replacement of the anode bar The protective anode equipped for Haier heat-pump water heaters can prolong service life of its products effectively. The magnesium anode, which shall be replaced in time, shall be checked typically once every 2 years according to different water qualities.
4. Cleaning of the air filter: The filter may be dedusted and cleaned every 3-6 months according to service conditions and dirt accumulation. It is located at the top of the water heater and can be pulled out by holding the filter handle upwards.
