Operational Conditions

Powered Anode Operation

To shelter the glass-lined water tank from corrosion through electrolysis, this water heater is equipped with a non-sacrificial powered anode which should not need to be replaced under normal operating conditions.

If the powered anode malfunctions it should be replaced by a qualified technician.

IMPORTANT: If a faulty powered anode is not repaired or has been removed permanently, then all warranties are void.

Water Heater Sounds

During the normal operation of the water heater, sounds or noises may be heard. These noises are common and may result from the following:

1.Normal expansion and contraction of metal parts during periods of heat-up and cool-down.

2.Sediment buildup on or around the elements could create varying amounts of noise and may cause premature tank failure. Drain and flush the tank as directed under the “Draining and Flushing” section.

3.The heat pump compressor or fan running.

Stacking

Stacking occurs when a series of short draws of hot water (3 gallons or less) are taken from the water heater tank. This causes increased cycling of the heat pump and/

or heater elements and can result in increased water temperatures at the hot water outlet. An anti-scald device is recommended in the hot water supply line to reduce the risk of scald injury.
