￿WARNING

￿CAUTION

Tank must be full before unit is turned on! The heating element will be damaged if energized for even a short period of time while tank is dry!

Be sure to ground the water heater. The preferred way to ground is to use rigid metal conduit between the main panel and the water heater junction box with approved end fittings. The separate ground wire connection provided in the water heater junction box must also be grounded. Replace the junction box cover and insulation after you have made all wiring connections.

The 4500-watt heating element in the Squire SET is wired to the junction box on top of the heater and it requires 240-volt/ A.C. electrical service. The voltage requirement and wattage load for the heater is also specified on the heater identification plate. A 1/2” E.M.T. opening, located on top of the unit is provided for a field wiring connection. Consult an electrician to determine if your electrical service is adequate for the additional load of the heater. The electrical installation should be done by a qualified licensed electrician. All wiring must conform to the National Electric Code and local codes.

After the water and electrical connection have been made and the tank has been filled with water, turn on the power to heater. The heater is now operational.

Thermostat Adjustment

The thermostat is located in the front of the heater. The access cover must be removed to adjust to the factory default setting of 120°F. This temperature is satisfactory for the average household use.
