FLUSHING THE SOLAR COLLECTORS
It may be necessary to flush the solar collectors if there is sediment in the water
supply. To flush the solar collectors, follow the procedure “Bleeding the Solar
Collectors” on page 7, 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.
FREEZE PROTECTION
The system is suitable for installation, and offers protection against freeze damage,
in areas up to 800 metres altitude. The system is not covered for freeze damage
above 800 metres altitude (refer to “Warranty” on page 40).
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 solar control unit. Damage caused by freezing due to no
power at the solar control unit, 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 800 metres altitude.
