Basic Operation Fundamentals
The Heat Pump Water Heater (HPWH) is an integrated
heat pump water heater unit, having an 850 watt
compressor and external coil heat exchanger with backup
electric elements (See Figure 1). When in Ef
fi
ciency Mode
the heat pump draws heat from the ambient air in the room
and transfers it to the water in the tank through the coil
heat exchanger. While in Electric Mode the water heater
functions like a standard electric water heater, relying on
the electric elements to heat the water. A Hybrid Mode is
available that relies primarily on the heat pump to heat
the water while the electric elements only function during
high demand periods. (See “Adjusting the User Interface
Module/ Operational Mode” section). The more often
the unit operates using the heat pump, rather than the
elements, the more ef
fi
cient the unit will be.
The tank capacity of this heat pump water heater is sized to
maximize the use of the heat pump to deliver hot water at
a lower cost as compared to heat pump waters with lower
tank capacities 50 gallons (189 litres) or less.)
The HPWH uses about half the electricity of a comparably
sized conventional electric water heater when operating
in the Ef
fi
ciency Mode, and provides up to ½ ton cooling
capacity and dehumidi
fi
cation. It is designed for indoor,
residential applications for installation in a basement,
garage or utility room (See “Location Requirements”
section).

Unpacking the Water Heater
WARNING
Excessive Weight Hazard
Use two or more people to move and install
water heater.
Failure to do so can result in back or
other injury.
Removing Packaging Materials
IMPORTANT:
Do not remove, cover or deface any
permanent instructions, labels, or the data label from either
the outside of the water heater or on the inside of water
heater panels.
•
The water heater must NOT be placed on its side. It
should be transported and stored in an upright position.
•
Remove exterior packaging and place installation
components aside.
