Care and cleaning.
DRAINING THE WATER HEATER
CAUTION:
Risk of Shock -
the water heater before draining water.
DANGER:
Risk of Scald -
operating the relief valve, make certain no one will be exposed
to the hot water released by the valve. The water drained from
the tank may be hot enough to present a scald hazard and
should be directed to a suitable drain to prevent injury or
damage.
To drain the water heater, follow these steps:
1. Attach a garden hose to the drain valve located at the
bottom of the unit and direct that hose to a drain.
EXTENDED SHUTDOWN PERIODS OR VACATIONS EXCEEDING VACATION MODE OPTIONS
If the water heater is to remain idle for an extended period of
time, the power and water to the appliance should be turned
off and the water heater drained to conserve energy and
prevent a buildup of dangerous hydrogen gas. This unit has
no power button, power can only be shut off at the circuit
breaker or disconnect switch.
If the water heater has an anode depletion sensing feature
(some models) and the water heater cannot be drained, it is
recommended to leave the power turned on with the water
heater in vacation mode to ensure that the feature will
continue to operate properly while still conserving energy.
CLEANING THE FILTER
In the Hybrid, Heat Pump and High Demand/Boost modes, the heater
moves air through the system and out the back of the unit. The filter
is in place to protect the evaporator from dirt and dust.
A clean air filter is important to get the highest efficiency. Occasion-
ally this filter will need to be cleaned (minimum once per year). When
the filter requires cleaning, the Red light above the Filter button will be
illuminated and an audible beep will sound.
NOTE: If the filter gets too dirty, the unit will automatically switch to
Electric/Standard mode and energy savings will be lost.
Leave the power on. Remove the filter from
the top of the unit. Squeeze 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.
Once the filter has been cleaned and dried, it can be replaced by
aligning it into the slots in the top of the unit and pushing it down into
place.
CLEARING THE CONDENSATION DRAIN TUBE
The main drain is intended to carry all condensate away. 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.
Periodically inspect the drain lines and clear any debris that may
have collected in the lines.

Before manually
2. Turn off the cold water supply.
3. Admit air to the tank by opening a hot water faucet or
lifting the handle on the relief valve
4. Open the drain valve with a flat screwdriver.
Note: See page 15 for product schematic.
Use a flat slot
screwdriver to
turn valve.
The water heater and piping should be drained if they might
be subjected to freezing temperatures.
After a long shutdown period, the water heater's operation
and controls should be checked by qualified service
personnel. Make certain the water heater is completely filled
again before placing it in operation.
NOTE: Refer to the Hydrogen Gas Caution in the Operating
Instructions (see page 3).
After the clean filter has been reinstalled, press and hold the FILTER
button. If a heating cycle is on when the filter fault is reset, it will con-
tinue in electric mode to finish the cycle. After that, it will automati-
cally revert to the mode it was in prior to being switched.
IMPORTANT: Filter must be cleaned when the alarm is displayed. A
dirty filter will make the system work harder and result in a reduction
of efficiency and possible damage to the system. In order to get the
best energy efficiency available, make sure your filter is clean.
