Initial Start-up
Upon power-up:
1. Default settings are hybrid mode and a water temperature setting of 120°F.
2. 0 to 2 minutes: Unit is silent. This 2-minute off-time prevents compressor damage.
3. 2 to 10 minutes: Compressor and fan turn on. This period is used to ensure the tank is full of water - dry
tank test.
4. 10 to 30 minutes: Compressor and fan turn off. Upper heating element turns on for about 20 minutes to
quickly provide initial amount of hot water.
5. 30 minutes and beyond: The upper element turns off and the compressor turns back on. Uses heat pump
for majority of heating.
6. The green LED beside the operating mode pad will be lit.
Note: The heat pump operating range is 45°F to 120°F. 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.
