Rheem Water Heater - Manual (Page 53)

AUXILIARY PUMP

The solar monitor located on the lower front cover is connected to the solar
control module by a ribbon cable. The ribbon cable has sufficient length to
enable the removal of the lower front cover and for it to be set to one side of the
opening without disconnecting the ribbon cable from the solar control module.
The ribbon cable can be disconnected from the solar control module if it is
necessary to remove the lower front cover completely from the work area in
front of the solar storage tank.
If the ribbon cable from the solar monitor has been disconnected, reconnect it
to the solar control module prior to replacing the lower front cover.
Note: Care should be taken when reconnecting the ribbon cable to the solar
control module to ensure the side of the connecting plug with the yellow label is
facing toward the front cover opening. The connecting plug is non polarised
and if it is connected with the side of the connecting plug with the yellow label
facing away from the front cover opening, the functions of the green and red
LEDs will be reversed. This will result in the red LED flashing instead of the
green LED at solar pump start up.
