Table 1.1 System Model Number
1.5 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
models are warranted against freezing. See separate instructions and guidance on these
models.
If the unit is to be fitted in areas prone to frost and freezing the unit must be installed in
accordance with any relevant sustainability programme (such as the Sustainability
Victoria program).
Closed circuit tanks must be installed and charged in accordance to Conergy
requirements. Transfer fluid used must be warranted against frost and freezing.
A breach of this requirement may void the warranty in the event of damage caused
by leaking due to frost or freezing.
