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. If the collector glass becomes dirty, hose down or if the
solar collectors are accessible, wash the collector glass with water and a soft brush when the solar
collectors are cool. Have any trees trimmed which may shade the solar collectors.
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 in the morning, within three hours of sunrise, when the water temperature inside the solar
collector(s) is lower.
•
Open a hot water tap and allow the water to run for five (5) minutes prior to flushing the solar
collector(s).
•
Close the hot tap.
•
Wait a further five (5) minutes before attempting to flush the solar collectors.
This will assist in the transfer of any high temperature water in the solar collector(s) to the solar
storage tank.
Warning: Exercise care, as water discharged from the solar collectors may be of a very high
temperature.
•
To flush the solar collectors, follow the procedure
allowing the water to flow from the bleed valve drain line for five (5) minutes before closing the
bleed valve.
It is recommended to flush the solar collectors every five (5) years. This will assist in keeping the solar
collectors, solar cold pipe and solar hot pipe clear of sediment.
