DRAINING THE SOLAR COLLECTORS

To drain the solar collectors and the solar hot and cold pipe:

Turn off the water heater (refer to “To Turn Off the Water Heater” on page 35).

Using a flat bladed screw driver, open the bleed valve fitted adjacent to the
5 way tee at the cold water inlet of the water heater (refer to diagram on
page 34).

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 cold pipes.

When water stops flowing from the solar hot and cold pipes, reconnect the
solar cold pipe to the circulator and tighten the compression fitting. Close the
bleed valve.

DRAINING THE WATER HEATER

Switch off the electrical supply at the isolating switch to the solar storage tank
and at the power outlet for the solar control unit.

Close the cold water isolation valve at the inlet to the water heater. Close all
hot water taps.

Operate the relief valve release lever - do not let the lever snap back or you
will damage the valve seat. Operating the lever will release the pressure in the
water heater.

Undo the union at the cold water inlet to the 5 way tee and attach a hose. Let
the other end of the hose go to a drain.

Operate the relief valve again. This will let air into the water heater, and allow
the water to drain through the hose.
