DRAINING THE SOLAR COLLECTORS
To drain the solar collectors and the solar hot and solar cold pipes:
• Open a hot water tap and allow the water to run for five minutes
immediately prior to draining the solar collector(s).
This will assist in the transfer of any high temperature water in the solar
collector(s) to the solar storage tank.
• Close the hot water tap.
Warning: Exercise care, as water discharged from the solar collectors
may be of a very high temperature.
• Turn off the water heater (refer to “To Turn Off the Water Heater” on
page
47).
• Using a flat bladed screw driver, open the bleed valve fitted adjacent to the
solar hot water inlet of the water heater
(refer to diagram on page 46).
• Undo the compression fitting at the side of the air duct of the solar storage
tank and disconnect the solar cold pipe.
Water will now drain from the solar collectors and the solar hot and solar
cold pipes.
• When water stops flowing from the solar hot and solar cold pipes, reconnect
the cold pipe to the solar storage tank and tighten the compression fitting.
• Close the bleed valve.
