Rheem Solaraide HE Use and Care Manual - Page 5

Installation Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact live electrical parts and to eliminate potential water damage. Piping used should be of a type approved for hot water distribution. The discharge line must be no smaller than the outlet of the valve and must pitch downward from the valve to allow complete drainage (by gravity) of the relief valve and discharge line. The end of the discharge line should not be threaded or concealed and should be protected from freezing. No valve of any type, restriction or reducer coupling should be installed in the discharge line. electrical fitting is provided for field wiring connections. (Refer to Fig. 3) The voltage requirements and wattage load for the water heater is specified on the rating plate on front of heater. Table 1 recommends minimum branch circuit sizing based on National Electric Code. Refer to wiring diagram on back cover of this manual for field wiring connections. ! CAUTION 6. TO FILL WATER HEATER - Make certain drain valve is completely closed. Open shut-off valve in cold water supply line. Open each hot water faucet slowly to allow air to vent from the water heater and piping. A steady flow of water from the hot water faucet(s) indicates a full water heater. The presence of water in the piping and water heater does not provide sufficient conduction for a ground. Non-metallic piping, dielectric unions, flexible connectors etc. can cause the water heater to be electrically isolated. The branch circuit wiring should include either: ! WARNING Tank MUST BE full of water before power is turned on. Heating element WlLL BE DAMAGED if energized for even a short time while tank is dry. The water heater's warranty does not cover damage or failure resulting from operation with an empty or partially empty tank. (Reference is made to the limited warranty for complete terms and conditions.) 7. ELECTRICAL CONNECTIONS for Electric Solar Only- A separate branch circuit with copper conductors, overcurrent protective device and suitable disconnecting means must be provided by a qualified electrician. All wiring must conform to local codes or latest edition of the National Electrical Code ANSI/NFPA 70. The water heater is completely wired to the junction box inside jacket at top front of water heater.

Metallic conduit or metallic sheathed cable approved for use as a grounding conductor and installed with fittings approved for the purpose. B. Non-metallic sheathed cable or metallic conduit or metallic sheathed cable not approved for use as a ground conductor shall include a separate conductor for grounding. It should be attached to the ground terminals of the water heater and the electrical distribution box. (Refer to Fig. 3) ! CAUTION The manufacturer's warranty does not cover any damage or defect caused by installation, attachment or use of any type of energy saving or other unapproved devices (other than those authorized by the manufacturer) into, onto or in conjunction with the water heater. The use of unauthorized energy saving devices may shorten the life of the water heater and may endanger life and property. The manufacturer disclaims any responsibility for such loss or injury resulting from the use of such unauthorized devices. If local codes require external application of insulation blanket kits the manufacturer's instructions included with the kit must be carefully followed. ! WARNING Application of any external insulation to this water heater will require careful attention to the following: • Do not cover the temperature and pressure relief valve. • Do not cover jacket access panel to thermostat and heating element. • Do not cover electrical junction box of water heater. • Do not cover operating or warning labels attached to the water heater nor attempt to relocate them on exterior of insulation blanket.
