Is the system suitable for extremely cold climates?
The open circuit system is not suitable for frost prone or freeze areas. If you are in a frost
prone or freeze area you must install a closed circuit system.
Whilst frost valves may be used to protect from mild damage of frosts to collectors,
installing a frost valve will not guarantee against frost damage. Damaged sustained to
the system in the event of freezing is not covered under warranty. Only closed circuit AS
models are warranted against freezing. See separate instructions and guidance on these
models.
