Frost Protection
Consult the table right to determine if
your system needs an anti-frost valve.
If your model does require frost
protection, you must install an anti-frost
valve.
However, TWO anti-frost valves must
be installed if you live in alpine areas or
areas subject to extreme frost, such as
the ACT and Snowy Mountain regions.
The anti-frost valve comes in kit form
and must be ordered seperately.
