Anti-Frost Valve
Step 18
• 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 separately.
