INSTALLATION – SYSTEM
25
FREEZE PROTECTION
The system, whether it is installed with a single element model tank or a frost element model tank, has a
level of freeze protection designed to guard the system against damage from freeze conditions. The system
must be installed with the full length of the solar hot and solar cold pipes insulated and power must be
available at the solar control unit to offer protection against freeze damage (refer to
on page 38). Freeze conditions occur below 6°C.
A system has NO WARRANTY for freeze damage when installed above 400 metres altitude or if the solar
hot and solar cold pipes are not insulated in accordance with the installation instructions or if power is not
available at the solar control unit (refer to
“Terms of the Solahart Warranty”
on page 53).
Note:
The Solahart
warranty against freeze damage applies only to systems installed in Australia.
INSTALLATION STANDARDS
The water heater must be installed:
by a qualified person, and
in accordance with the installation instructions, and
in compliance with Standards AS/NZS 3500.4, AS/NZS 3000 and all local codes and regulatory authority
requirements.
In New Zealand, the installation must also conform with Clause G12 of the New Zealand Building Code.
Victorian Installers
Notice to Victorian Installers from the Victorian Plumbing Industry Commission if this solar water heater is
installed in a new Class 1 dwelling in the State of Victoria. The system model number is to be recorded on
the Certificate of Compliance. It is also a requirement to provide the householder with permanent
documentation recording the syste
m model number exactly as it is shown in the „List of systems capable of
complying with the regulations‟ published by Sustainability Victoria (see www.sustainability.vic.gov.au). This
documentation may be in the form of an indelible label adhered to the solar storage tank, or other suitable
form placed in an accessible location, such as the meter box, for later inspection.
WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable
water. Its use in an application other than this may shorten its life.
If this water heater is to be used where an uninterrupted hot water supply is necessary for the application or
business, then there should be redundancy within the hot water system design. This should ensure the
continuity of hot water supply in the event that this water heater was to become inoperable for any reason.
We recommend you provide advice to the system owner about their needs and building backup redundancy
into the hot water supply system.
This water heater is designed to be installed as an electric boosted solar water heater with its booster
heating unit connected to a power supply, however it may be installed with an in-series continuous flow or
storage booster.
If this water heater is installed with an in-series booster, then the electric booster heating unit will not be
connected to a power supply and the references to the electric booster heating unit, thermostat and boosting
controls in these installation instructions will not be applicable to the installation.
Note:
AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in
potable water. This water heater can satisfy this AS 3498 requirement provided the electric booster is
energised for a sufficient period each day and the electric booster thermostat setting is 60°C or higher.
If this water heater is installed with an in-series continuous flow gas booster, then this requirement of
AS 3498 can be satisfied provided the booster is energised, its preset outlet temperature setting is 70°C or
higher and a remote temperature controller is not used.
If this water heater is installed with an in-series storage booster, then this requirement of AS 3498 can be
satisfied provided the storage booster is energised and its thermostat setting is 60°C or higher.
