EAGLE SUN™OPEN (DIRECT) STORAGE TANK - PART # OST-TCE

Models – 80 and 120 gallon capacities

1 – R-Foam Insulation (R-14) – Rigid Polyurethane foam insulation for optimized operation. Electric control is covered by fiberglass insulation for easy accessibility.

2 – Tank – Thermos-Miser™ water heater tanks are made with exacting care. The tank surface is coated with an exclusive porcelain formula and fused to the solid steel shell at 1600O. The result is a smooth, tough, glass like lining. Tank is designed and tested to withstand 300 PSI hydrostatic test pressure of 150 PSI U.L. Standard.

3 – Collector Return - is provided through dip tube at top of tank for ease of connection and efficiency.

4 – Cold Water Inlet - brings cold water to tank bottom to prevent mixing with already heated water.

5 – Anode Rod - protects inner tank. Additional opening in top pan for easy access to anode rod.

6 – Cold Water Inlet, Hot Water Outlet, Relief Valve and Anode Rod are at tope of tank for easy access and fast, economical installation.

7 – Collector Feed Opening – Located at the top of the tank. Dip Tube prevents mixing of hot water in the top of the tank and draws cold water from the bottom of the tank.

8 – Threaded Sensor Stud – Located for positive tank sensor mounting. Low voltage sensor wire runs inside jacket and out top of tank for easy control connection.

9 – Relief Valve Opening – Located for convenient installation.

10 – Bottom Pan is secured by a special lug on tank bottom eliminating need for sheet metal screws. The lug serves as a ground and also locks tank to pan to prevent “floating action.”

11 – Improved Electrical Junction Box (for ½” and ¾” conduit) placed above heating element for easy installation. No spot welds used.

12 – Direct Immersion Heating Element is completely immersed – all the heat goes into the water Nickel Chromium heating coil imbedded in magnesium oxide and sealed in a tinned-copper tube. Although in direct contact with water, the ends are sealed to prevent entrance of moisture. Elements are changed, should the need arise, by screwing into special tank flanges.

13 – Automatic Temperature Control Thermostat keeps stored water at desired temperature.

14 – High Temperature Limit automatically and safely cuts off power to the element should excessive temperature occur.
