Consumer Responsibilities

This manual has been prepared to acquaint you with the 

installation, operation and maintenance of your electric heat 

pump water heater and to provide important safety information 

in these areas. 
We urge you to read all of the instructions thoroughly before 

attempting the installation or operation of this water heater. 

This manual should be kept for future reference.
The manufacturer of this water heater will not be liable for any 

damages caused by failure to comply with the installation and 

operating instructions outlined in this manual. 
If you lack the necessary skills required to properly install this 

water heater or you have difficulty following the directions, you 

should not proceed but have a qualified person perform the 

installation of this water heater.

Examples of a qualified person include: licensed plumbers, 

authorized electric company personnel, and authorized 

service personnel.

Massachusetts code requires this water heater to be installed 

in accordance with Massachusetts 248-CMR 2.00: State 

Plumbing Code and 248-CMR 5.00.  
A data plate identifying your water heater can be found 

adjacent to the upper element door. When referring to your 

water heater always have the information listed on the data 

plate readily available, to include the model and serial number.
Retain your original receipt as proof of purchase.

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 Efficiency 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 efficient 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 or less.)
The HPWH uses about half the electricity of a comparably 

sized conventional electric water heater when operating 

in the Efficiency Mode, and provides up to ½ ton cooling 

capacity and dehumidification.  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.
