  • Page 4: Water Heater Capacity

    General Information cont.- Water Heater Capacity Water Heater Capacity and Increasing Temperature Setpoint: The water heater temperature setting strongly impacts the amount of usable hot water available for showers and baths. • Energy consumption/savings and efficiency testing of water heaters is performed according to the Department of Energy (DOE) requirements specified at the date of manufacture.
  • Page 5: About The Control Panel

    General Information cont.- About the Control Panel Displaying Temperature Setpoint The water heater control will display the temperature setpoint anytime a button on the control is pressed. After 30 seconds of inactivity, the display will go blank. However, the LED indicating the selected operation mode will remain lit.
  • Page 6: Operational Modes

    General Information cont.- Operational Modes This water heater defaults to the Hybrid operating mode. To select available modes listed below: 1. Press the MODE button until the LED next to the desired Operating Mode is illuminated. In Hybrid Mode, the Electric (Only) Mode LED will flash anytime the heating elements are active, such as during the initial recovery from a large draw.
  • Page 7 General Information cont.- Vacation Mode This feature is recommended when you will be away from the home for an extended period of time and hot water is not needed. In this mode, the unit will reduce the water temperature setting to 50°F (10°C) and will use the most efficient heating mode to conserve energy while the heater is sitting idle.
  • Page 8: Temperature Adjustment

    Temperature Adjustment CAUTION Increasing the thermostat setting above the preset temperature may cause severe burns and consume excessive energy. Hotter water increases the risk of scald injury. This water heater can deliver scalding temperature water at any faucet in the system. Be careful whenever using hot water to avoid scalding injury. Certain appliances, such as dishwashers and automatic clothes washers, may require increased temperature water.

  • Page 10 Installation Instructions cont.- The location of this water heater is to be installed is of utmost importance. Before installing this water heater, consult the installation section of these instructions. After reading these installation and operating instructions, select a location for the water heater where the floor is level and is easily accessible to a power supply and water connections.
  • Page 11 Ensure that the rear of the water heater is open and not discharged against a wall. A ducting kit may be required in order to achieve optimum efficiency. Bradford White is not liable or responsible for any additional energy consumption or warranty implications.
  • Page 12: Minimum Required Clearances

    Installation Instructions cont.- Minimum Required Clearances NOTE: Installations in a confined space, or installations where the recommended service clearances are not met, will lead to higher power consumption (increased use of resistance heating elements and/or heat pump efficiency reduction). Corner Installation T&P Valve Front of T&P Valve...
  • Page 13 Installation Instructions cont.- Condensate Drain Connection ¾” MNPT This unit has a condensate drain; therefore, a floor Condensate ¾” MNPT Drain Port or other drain no higher than 36 in (91.4 cm) above Condensate Drain Port the floor must be available. It must be in close proximity to the water heater to allow for the shortest possible drain line with minimal turns.
  • Page 14: Water Supply Connections

    Water Supply Connections Note: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE. After shutting the main water supply valve, open a faucet to relieve the water line pressure to prevent any water from leaking out of pipes while making the water connections to the water heater. After the pressure has been relieved, close the faucet.
