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 (17.5 cm), and sides have at least 7 inches (17.5 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:
– Main Drain Installed
4. Temperature and pressure-relief valve is working and drain line completed per local code.
5. Electrical verify 208/240 VAC to L1 and L2 at tank.
6. Electrical connection does not prevent air filter removal.
7. Verify control panel displays 120°F (49°C) Hybrid mode. Assist user in how to adjust temperature and modes (see
“About the Water Temperature Setting” section on page 7).
WHAT TO EXPECT fOr “NOrMAL sTArTUP” IN HybrID MODE
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, you may experience the following:
Elapsed Time
HEWH Actions
Comments
0 to 2 minutes
Unit will go through self-check.
This 2-minute off-time prevents compressor
damage.
2 to 10 minutes
Compressor and fan turn on
This 8-minute period is used to ensure the tank is
full of water (Dry-fire prevention algorithm).
10 to 30 minutes
Compressor and fan turn off, heat-
ing elements turn 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
compressor 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 electric elements will be used until the ambient temperature returns to within the
operating range.
