INSTALLATION CONSIDERATIONS
ELECTRICAL REQUIREMENTS
Grounding
Review the electrical ground requirements given in the Instruction Manual that came with 
the water heater and ensure the water heater has been properly grounded.
The water heater must be grounded in accordance with the National Electric Code and/or 
local codes. These codes must be followed in all cases.
The water heater must be connected to a grounded metal, permanent wiring system; or an 
equipment grounding conductor must be run with the circuit conductors and connected to 
the equipment grounding terminal or lead on the water heater.
Service Note: Electronic Control Models (see Figure 2 on page 9) covered in this manual 
may experience erratic control operation if the water heater is not properly grounded.
Power Supply
Review the electrical requirements listed on the water heater’s rating label and in the 
Instruction Manual that came with the water heater. Ensure the branch circuit supplying 
power to the water heater is within these requirements and properly connected.
Ensure the power supply phase (single or three phase / 1Ø, 3Ø) and power supply voltage 
match the water heater’s rating label - see pages 12-14. The electric water heater models 
covered by this manual are phase convertible - see pages 15 and 16.
