see that they calibrate to 10K ohm resistance at 77°F. If you find a defective sensor replace it immediately. Note that in a two tank system nighttime heat loss will be harder to detect, especially if you are operating in the solar preheat mode. Check the line thermometers (No. 3) in the collector loop piping to detect night thermosiphoning.

9.10If the weather is poor and the auxiliary heating element will not fire, the bright red reset button on the thermostat may have to be depressed to be reset. Single tank systems have one heating element and thermostat. Double tank systems with conventional electric water heaters have two heating elements and thermostats (see fig 17, No. 29).

Never remove the protective access plate on the exterior of the solar storage tank or conventional water heater without disconnecting the 230 volt power supply at the circuit breaker.

After the circuit breaker has been turned off, remove the access plate on the storage tank or water heater and depress the red reset button on the thermostat. If it clicks when depressed the heating element should fire 30

immediately when you reconnect the circuit breaker. It the reset button does not click and you do not have hot water after one hour, the heating element or thermostat may be defective. Contact your installation contractor for service.

In two tank systems the conventional electric water heater will be wired for electrical back-up. The solar tank will serve solely as a storage tank and will not be wired.

10) Rheem SYSTEM COMPONENT PARTS

See Figures 16 and 17 for the location of the specific components numbered below.

1)Rheem Solar Collector(s): Absorbs the sun's heat energy and transfers this heat to the HTF circulating through the collector. (Provided)

2)Collector Sensor: Wired to the system controller. Works in conjunction with the tank sensor to automatically turn your circulating pump on and off at preset temperature differentials. (Provided)
