FREEZE PROTECTION
The system when installed in areas subject to freeze conditions must be
installed with the solar hot and solar cold pipes fully insulated with closed cell
polymer insulation (minimum thickness 13 mm) to offer protection against
freeze damage. Freeze conditions occur below 6°C. The system has NO
WARRANTY for freeze damage when installed above 400 metres altitude or if
the solar hot and solar cold pipes are uninsulated (refer to “Warranty
Exclusions” on page 59 and to “Pipe Work and Insulation” on page 8).
The anti freeze control is designed to recirculate a small amount of water from
the solar storage tank through the solar pipe work during periods of low
temperatures. This is to prevent the water inside the pipe work from freezing. It
is essential that the electrical circuit to the solar control unit is continually turned
on if there is a risk of freezing. The solar warranty does not cover damage
caused by freeze conditions when the electrical circuit to the solar control unit
is turned off or interrupted.
Notes:
• If it is necessary to switch the power off to the solar control unit and there is
a risk of freezing, then it is necessary to have your plumber drain the solar
collectors and solar flow and return pipe work.
• The freeze protection system will be rendered inoperable if electrical power
is not available at the water heater. Damage caused by freezing due to no
power at the water heater, is not covered by warranty.
• Pipe work between the solar collectors and solar storage tank must be
insulated.
• The system is not covered for freeze damage above 400 metres altitude.
