INSTALLATION CHECkLIST
1. Tank location:
– does room size require louvered door or similar ventilation? 10’ x 10’ x 7’ (700 cu. ft.) or 240 square inches (0.15 m 2 )
air-flow area needed.
– Back of unit away from wall by 7 inches (17.8 cm), and sides have at least 3 inches (7.6 cm) clearance.
– front of unit is free and clear.
– Is the water heater level? If no, add shims under the base of the unit.
2. Plumbing connections:
– does not prevent air filter removal.
– no leaks after filling the tank with water, either when water is flowing or not.
3. Condensate lines are in place:
1) Short tube on upper drain nozzle.
2) Longer tube on lower drain nozzle and directed into a floor drain or a condensate pump.
4. Temperature and pressure-relief valve is working and drain line completed per local code.
5. Electrical connection does not prevent air filter removal.
6. Verify control panel displays 120°F (49°C) Hybrid mode. Assist user in how to adjust temperature (see “About Setting
the Water Temperature” section on page 5).
7. Front cover is in place.

WHAT TO EXPECT fOR “NORMAL STARTUP”
After the unit has been installed, with all electrical and water connections secure and checked, then the unit should be
filled with water (vent tank by opening a hot water faucet somewhere in home to allow tank to fully fill with water). Once
tank is full and power is energized, the user must press the POWER button on the user interface. The unit will then remind
the user to ensure tank has been filled, and to acknowledge by pressing POWER again.
Elapsed Time HEWH Actions Comments
0 to 1.5 minutes unit is silent This 3-minute off -time prevents compressor
damage.
1.5 to 3 minutes Fans turn on
3 to 8 minutes Compressor turns on and runs for
5 minutes
This 5-minute period is used to ensure the tank is
full of water (dry-fire prevention algorithm).
8 to 30 minutes Compressor turns off, and upper
Element turns on for about
20 minutes
To quickly provide initial amount of hot water for
user (about 25 gallons/94.6 L).
30 minutes and
beyond
upper element turns off and com-
pressor turns back on
uses efficient heat pump for majority of heating
nOTE: The heat pump operating range is 45°F to 120°F (7°C to 49°C). If the ambient temperature is outside of this range,
the heat pump will turn off and the backup electric elements will be used until the ambient temperature returns to within
the operating range.
