water heater. A screw is provided in the juncon box
for the grounding connecon.
The water heater requires 120 VAC, 60 Hz power from

If using the 5 foot long power cord, plug it into a
standard 3 prong 120 VAC, 60 Hz properly grounded
wall outlet.
On outdoor models, a disconnect switch must be
provided and installed for the incoming 120 VAC
power. It should be a type that is suitable for outdoor
use. Check the Naonal Electrical Code, ANSI/NFPA
70 and your local codes for a proper switch type to
use in your area.
