Maintenance cont.-
To clean the filter:
1. Leave the power ON.
2. Remove the filter from the top of the unit.
3. Squeeze the two tabs and lift to remove the air filter.
Once it has been removed, the filter can be
vacuumed or wiped clean with a damp cloth or
rinsed with warm water.
4. Once the filter has been cleaned and dried, it can be
replaced by aligning it into the slots into the top of
the unit and pushing it down into place.
5. After the clean filter has been reinstalled, press
and hold the FILTER button to reset the alarm.
The unit will automatically revert to the previously selected operating move. If a heating cycle is active when
the filter alarm is reset, it will continue in Electric (Only) mode to finish the cycle, then automatically revert to
the previously selected mode.
Note: If the dirty filter alarm returns within a few days after cleaning and resetting, it may be an indication of a
refrigerant leak. Further diagnosis by a service technician is necessary.
Clearing the Condensation Drain Tube
The main drain is intended to remove all
condensate. If it is clogged, the heat pump will
stop operating, the display will show F20, and an
alarm will sound. Press any button to silence the
alarm, then clear the condensate drain by
removing any drain lines and connections and
clearing debris. Reattach drain lines and
connections, then allow the water heater to run.
The water heater will continue to produce hot
water using the backup resistance heating
elements until the condensate drain has been
cleared and is able to drain properly. Once the
drain has been cleared, the unit will then be able
to operate the heat pump again.
Periodically inspect the drain lines and clear any
debris that may have collected in the lines.
Anode Rod
Anode rods are designed and installed to protect and extend the life of residential water storage tanks. The
anode rod must be removed from the water heater's tank and inspected annually and replaced when more
than 6 in (15.2 cm) of core wire is exposed at either end of the rod.* Artificially softened water will cause the
anode rod to consume more rapidly.
Failure to replace the anode rod when consumed risks voiding the warranty for the tank. Warranty coverage
for all other components remains intact and is unaffected by this maintenance requirement. The replacement
anode rod, and the inspection for consumption are not covered by warranty.
Due to shock hazard and to prevent accidental water leaks, this inspection should be done by a qualified
servicer or plumber and requires that the electric power and cold water supply be turned OFF before servicing
the anode rod.
Do NOT remove the anode rod from the water heater's tank except for inspection and/or
replacement, as operation with the anode rod removed will shorten the life of the glass-lined tank
and will void warranty coverage.
