Hubbell Electric Heater Company CE110 - Manual (Page 8)

PIPING INSTALLATION
NOTE: The most effective means for preventing deterioration from accelerated corrosion
due to galvanic and stray current is the installation of dielectric fittings/unions. The
installation of these fittings is the responsibility of the installing contractor.
1. Connect the cold water inlet and hot water outlet to the appropriate connections as
shown; refer to installation diagram.
2. Provide a shut off valve in the cold water line. Mark for future emergency use.
3. If pressure reducers or any other restrictions are put in the cold water line, special
precautions should be taken. Consult your local plumbing inspector.
4. Install the combination temperature and pressure safety relief valve in the tapping
provided. Note that this is required by law for safety considerations.

5. Install a relief valve overflow pipe to a nearby floor drain. CAUTION: No valve of
any type should be installed between the relief valve and tank or in the drain line.
FILLING THE HEATER
1. Completely close the drain valve.
2. Open the highest hot water faucet to allow all air to escape from piping.
3. Open the valve to the cold water inlet and allow the heater and piping system to
completely fill, as indicated by a steady flow of water from the open faucet.
ELECTRICAL INSTALLATION
1. Enter the electrical service entrance with properly sized feeder leads, conforming to
the voltage stamped on the rating plate. Note: A separate fused branch circuit,
conforming to local or National Electric Codes, must be provided by a qualified
electrician.
2. Connect these power leads to wires enclosed in junction box with wire nuts. Refer to
wiring diagram.
CAUTION : There is a risk of electric shock in an ungrounded service. It is critical that
this unit be wired with a power supply that has a service ground wire available. Be
sure to connect the ground wire to the green ground wire provided in the junction box.
3. Mark the electrical shut off clearly for future emergency use.
4. Field connections with aluminum conductors must use connectors approved for
copper to aluminum connection.
5. All other electrical connections are made at the factory; therefore, no other electrical
connections are necessary.
