SOLAR MONITOR
The solar storage tank incorporates a solar monitor. The solar monitor is located above the lower front cover
and houses both a green and a red LED.
The green LED, marked "Solar", indicates the current operational mode of the solar water heater and the red
LED, marked "Attention", indicates a fault mode.
The green LED will emit either a constant glow or a series of flashes, with a two (2) second interval between
each series.
The red LED will emit a series of flashes, with a two (2) second interval between each series, only if there is a
particular fault condition with the system.
The operational modes are:
Flashes
Operational Modes
solid green
Standby mode
(remains on)
2 x green Flooding solar circuit
3 x green Pump flow control
4 x green Pump flow established
5 x green Tank at maximum temperature
no green
Call for service
(remains off)
If the power supply to the water heater is on and the green LED is off or the red LED is flashing, this indicates
there is a fault with the water heater. The red LED may emit up to six (6) flashes in each series of flashes.
Count the number of flashes and phone Rheem Service or their nearest Accredited Service Agent to arrange
for an inspection.
RAINWATER COLLECTION SYSTEM
If the solar collectors and solar pipe work are installed on a section of roof which is part of a rainwater runoff
collection system, then it is recommended this section of roof and its gutter be isolated from the rainwater
collection system.
The closed circuit fluid acts as an anti-freeze agent and rust inhibitor, is non-toxic to humans and is harmless
to the environment. However it does have an adverse effect on water stored in rainwater tanks. It will kill
microscopic algae typically present in rainwater tanks and cause an unpleasant odour to develop. This will
result in the rainwater tank having to be drained and cleaned.
If a rainwater tank does become contaminated with closed circuit fluid, then the following actions should be
undertaken by a qualified person. Additional actions may be necessary to return the water supply to a
consumable state.

Correct the leak or spillage.

Wash down the roof area where the spill or leak has occurred.

Flush out the gutters and down pipes.

Determine how the closed circuit fluid made its way into the rainwater tank. If the section of roof supporting
the solar water heater is not isolated from the rainwater collection system, then this should be remedied.

Empty the rainwater tank, and clean out all algae from the inside of the tank.

Refill the rainwater tank with fresh water.
