DRAINING AND FLUSHING
The WatterSaver

being shut down in freezing temperatures. It is rec-
ommended that the water tank be flushed every 6
months to remove sediment that builds up during op-
eration. To drain and flush this water heater:
1. Disconnect power to the unit.
2. Close the cold water inlet valve and open a
nearby hot water faucet.
3. Connect a hose to the drain valve and termi-
nate it at an adequate drain.
4. Open the drain valve and allow the tank to
drain, periodically opening and closing the cold
water inlet valve to flush sediment from the tank.
5. When clear water is observed coming from
the drain hose, close the drain valve and dis-
connect the hose.
6. Open the cold water inlet valve to refill the
tank with water.
7. Close the hot water faucet when water be-
gins flowing from it.
8. Restore power to the unit.
9. Refer to “Start Up Procedures” in this
manual.
IMPORTANT: If the water heater is going to be shut
down for an extended period, the drain valve should
be left open.

CLEANING THE WATTERSAVER™
• The air filter should be cleaned at least twice a year
or whenever it is visibly dirty. A dirty filter reduces air
flow to the heat pump’s evaporator coil, resulting in
decreased efficiency. To clean the filter, remove it from
the shroud by pulling it away from the hook fasteners.
then vacuum it or wash it in warm water with a mild
soap and pat it dry before replacing it.
• The outer surfaces of the WatterSaver™ Heat Pump
Water Heater may be cleaned with a sponge and warm
soapy water. Do not use bleach, abrasive cleaners, or
solvents which will damage the unit’s finish.
