Important Safety Information
1. You must read and follow all instructions. Serious bodily injury or death could occur
if you ignore this warning.
2. All circuit breakers and/or disconnect switches servicing the heater must be turned off
when installing, uninstalling, or repairing this water heater.
3. The Hubbell Tankless Water Heater must be grounded.
4. The unit must be installed by a licensed electrician and plumber.
5. The unit must be wired in accordance with the current version of the National
Electrical Code (US) or Canadian Electric Code (Canada).
6. This installation must comply with all national, state, and local plumbing and
electrical codes.
7. When the heater is not within sight of the electrical circuit breakers, an additional
local means of disconnection of all ungrounded conductors must be provided that is
within sight of the appliance or a circuit breaker lockout must be used. (Ref. NEC
422.31)
8. If the Hubbell Tankless Water Heater is installed in a location where water damage
could occur in the event of a leak, it is recommended that a drip pan be installed and
connected to a suitable drain. Alternatively, an active water leak detector and shut off
valve can be installed to turn off your water supply in the event a leak is detected.
9. It is recommended that water hardness levels in excess of 12 grains per gallon
[approx. 200ppm (mg/l)] be treated prior to entering the water heater. Unless treated,
water at or above this hardness level will cause scaling which will significantly impact
the water heater performance.
10. When the heater is installed in a well water system or if the plumbing system is prone
to introducing air into the heater, it is highly recommended that an air separator be
installed in the cold water feed to the heater to avoid possible failure of the heating
element and/or heating chamber.
