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
collectors is lower.
Open a hot water tap and allow the water to run for five (5) minutes prior to flushing the solar collectors.
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 collectors 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
“Bleeding the Solar Collectors”
on page 9, allowing the
water to flow from the bleed valve drain line for five minutes before closing the bleed valve.
It is recommended to flush the solar collectors every five years. This will assist in keeping the solar
collectors, solar cold pipe and solar hot pipe clear of sediment (refer to
“Major Five Year Service”
on
page 11).
