Rheem RS80-40BP, RS120-64BP, RS80-48BP installation instructions

3)Tank and Line Thermometers: Used to determine proper system operation. Line thermometers will show an approximate 5 - 12° temperature dif ference between the collector supply and return lines on sunny days. In a single tank system the tank thermometer will read the temperature of the water after the mixing valve feeding your fixtures. In two tank systems

the thermometer will read the finished solar tank temperature. (Provided)

4)Check Valve: This valve is installed to stop or minimize convective evening heat loss in the system. The heat in the solar storage tank will rise through the collector loop piping in the evening into the much cooler solar collector and dissipate heat unless prevented from doing so by a check valve. Check valves are also sometimes referred to as one way valves. (Provided)

5)Isolation Ball Valve: Used in conjunction with

component No. 10 to isolate the solar collector loop from the solar storage tank. (Not Provided)

6)Pressure Relief Valve: Will release glycol loop

HTF at 150 PSI. If this valve opens and HTF fluid is expelled contact your contractor immediately. This valve also can be opened to drain the HTF from the charged glycol loop for replacement. (Provided)

7)Pressure Gauge: Indicates the pressure in the charged glycol collector loop. (Provided)

8)Expansion Tank: Pre-charged with air to allow for the expansion and contraction of the glycol HTF as it heats and cools. (Not Provided)

9)Charge Valve: Used to charge the collector loop

with glycol and also to eliminate air from the system. (Not Provided)

10)Isolation Ball Valve: Used in conjunction with component No. 5 to isolate the solar collector loop from the solar storage tank. Also used with the charge valves to fill and pressurize the collector glycol loop

(Nos. 9 and 11). (Not Provided)

11)Drain/Purge Valve: Used to charge the collector loop with glycol, purge air from the loop and drain the heat exchange fluid. (Not Provided)

12)Isolation Ball Valve: When closed in conjunction with No. 14 will isolate the circulation pump for repair or replacement. (Not Provided)

13)Circulating Pump: Circulates the HTF through the collector loop. (Provided)

14)Isolation Ball Valve: When closed in conjunction with No. 12 will isolate the circulation pump for repair or replacement. (Not Provided)

15)Flush Valve: Used to drain the solar storage tank and to flush sediment from the tank on an annual basis. (Not Provided)

16)Tank Sensor: Wired to your controller. Works

in conjunction with the collector sensor to turn your circulating pump on and off at preset temperature differentials. (Provided)

17)Cold Water Dip Tube: Forces incoming city

cold water to the bottom of the solar storage tank to prevent mixing with the warm water at the top of the tank. (Provided)

18)Differential Thermostat: Known as the controller. Automatically turns the circulating pump on and off when there is sufficient heat to be gained from the solar operation. The controller also may be set to limit high temperature build up in the solar storage tank. (Provided)

19)Heat Exchanger: Transfers heat from the solar collector loop to the potable water in the solar storage tank. (Provided)

20)Anode Rod: The "sacrificial" anode rod is installed in your solar storage tank to prevent corrosion to the tank lining by neutralizing aggressive water action. Anode rods have a finite life and require periodic replacement depending on annual tank temperatures and water quality. Determine

a replacement schedule with your installation contractor. (Provided)

21)Heating Element & Tank Thermostat: The solar storage tank is equipped with an auxiliary 4500 watt, 230 volt electrical heating element. The thermostat controls the temperature setting of the auxiliary heating element. (Provided)
