DRAINING THE SOLAR COLLECTORS
To drain the solar collectors and the solar hot and solar cold pipe:
• 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 33).
• Using a flat bladed screw driver, open the bleed valve fitted adjacent to the solar hot water inlet of
the solar storage tank
(refer to diagram on page 33).
• Undo the compression fitting at the top of the circulator (located at the side of the solar control unit)
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 solar cold pipe to
the circulator and tighten the compression fitting.
• Close the bleed valve.
