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 2 second interval between each
series.
The red LED will emit a series of flashes, with a 2 second interval between each series, only if there is a
particular fault condition with the system.
The operational modes are:
Flashes

Call for service
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 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.
RAIN WATER TANK
If the solar collector and solar pipe work are installed on a section of roof which is part of a rain water runoff
collection system, then it is recommended this section of roof and its gutter be isolated from the rain water
collection system. The gutter should be isolated to a width greater than the solar collector and pipe work and
must have suitable drainage. This is to ensure in the event of a leak from the solar collector or pipe work, a
rainwater tank cannot be contaminated with closed circuit fluid.
The closed circuit fluid contains food grade additives (rust inhibitor and anti-freeze agent), is non-toxic and is
harmless to the environment. However, if it enters a rain water tank, it can kill off microscopic algae which
are typically present in the water causing an unpleasant odour to develop and resulting in the rain water tank
having to be drained and cleaned.
PRECAUTIONS
Where damage to property can occur in the event of the water heater leaking, the water heater must be
installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements.
The water heater must be maintained in accordance with the Owner‟s Guide and Installation Instructions.
Refer to “Regular Care” on page 11 and to “Anode Inspection and Replacement” on page 15.
If this water heater is to be used where an uninterrupted hot water supply is necessary for your application or
business you should ensure that you have back up redundancy within the hot water system design. This
should ensure the continuity of hot water supply in the event that this water heater were to become
inoperable for any reason. We recommend you seek advice from your plumber or specifier about your needs
and building back up redundancy into your hot water supply system.
