MAINTENANCE REQUIREMENTS

COLLECTOR GLASS
Ensure the glass on your solar collectors is free of dust, salt spray or any other matter which may reduce the
effectiveness of the solar collectors. Rainfall should keep the collector adequately clean. It is recommended
the collector glass be washed clean at least every three months should adequate rain not have fallen in this
period.
Collector glass can be hosed down or if the solar collectors are accessible such as on a trafficable roof, wash
the collector glass with water and a soft brush when the solar collectors are cool, such as early in the morning.
In extremely dusty areas extra attention may need to be given to keeping the collector glass clean.
Have any trees trimmed which may shade the solar collectors.
Rheem solar collectors have passed the AS/NZS 2712 requirements for resistance to hailstone damage, so it
is not normally necessary to fit a guard to a collector. Stone Guards are available to provide a level of protection
to the collectors against vandalism or accidental damage. Contact Rheem or your local Rheem Solar Water
Heater Distributor for details.
FLUSHING THE SOLAR COLLECTORS
It may be necessary to flush the solar collectors if there is sediment in the water supply. This should be
conducted by a person qualified to do so and in the morning within three hours of sunrise, when the water
temperature inside the solar collectors is lower.
Warning:
Care must be exercised to avoid splashing of water, as water discharged from the solar collectors
and solar storage tank may be of a very high temperature.
It is recommended to have the solar collectors flushed every five (5) years. This will assist in keeping the solar
collectors, solar cold pipe and solar hot pipe clear of sediment.
