100% Solar

open the controller and change the operational setting from automatic to off. Failure to turn off the pump can quickly damage the pump motor, shaft, bearings or impeller.

Two Tank System Instructions:

6.4 100% Solar Operation

Follow the instructions for single tank systems above. You also must change the position of the three way ball valves above both the solar storage tank and the back-up water heater (Nos. 24 and 26). Valve handle No. 24 must be in the horizontal position. Valve handle No. 26 must be in the vertical position. See Figure 19a, 100% Solar Operation.

6.5 Solar Preheat

Follow the instructions for the single tank system for setting the thermostat and the heating elements for automatic operation. The three way valve above the solar storage tank (No. 24) must be in the vertical position. Each valve handle (Nos. 24, 25 and 26) must be placed in the horizontal position. See Figure 19b, Solar Preheat.

6.6 100% Utility Power

Follow the instructions for the single tank system above. All three ball valves above the heaters (Nos. 24, 25 and 26) must have the valve handles placed in the horizontal position. See Figures 19c 100% Utility Power and 19d.

7)ISOLATING THE MAJOR COMPONENTS AND SYSTEM SHUT DOWN PROCEDURES

Your Rheem solar water heating system is designed so that the key components can be easily isolated for emergency repairs or routine maintenance. By shutting a single valve you can isolate the entire system from the pressurized cold water supply line (No. 23). In the case of a storage tank or fitting leak immediately shut this valve and call your installation contractor for service.

The collector loop can be isolated from the solar storage tank by closing isolation ball valves Nos.

5 and 10. If the pressure in this loop drops or you find a glycol leak shut these valves and contact your installation contractor. Turn the circulating pump off by setting the controller to the “off” position.

In two tank systems the solar storage tank can be isolated from the back-up water heater.

Set the valve handle on the three way ball valve (No.

24)to the horizontal position and close the isolation ball valve (No. 25). By closing these two valves the tank can be serviced or replaced. The operation of the back-up water heater will not be effected.

The back-up water heater in two tank systems also can be isolated from the rest of the system. Close the cold water supply line ball valve (No. 23) and set the three way valve handle above the conventional water heater (No. 26) to the vertical position. Set the two way ball valve handle (No. 30) directly above the heater to the horizontal position.
