FREEZE PROTECTION
The system 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
Plumber Be Aware"
on page 41). Freeze conditions occur below 6°C.
Note: The Rheem warranty against freeze damage applies only to systems installed in Australia.
The 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
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 or AS/NZS 3500.5:2012 Section 3 (for a Class 1a or

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 system model number exactly as it is shown in the 'VEET Product Register' published by the
Essential Services Commission in Victoria (see www.veet.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 back-up 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 back-up redundancy
into the hot water supply system.
This solar water heater is designed to be installed with a Rheem continuous flow 874 series 20 or 26 litre in-
series gas booster either mounted onto the storage tank or installed remotely, or a Rheem 874 series 27 litre
in-series gas booster installed remotely.
Warning: A model in-series gas booster greater than 26 litre capacity cannot be mounted on the solar
storage tank and may only be installed remotely. The size and weight of the gas booster may cause the solar
storage tank to topple over.
The solar water heater may be installed with another suitable type of remotely installed in-series continuous
flow or storage booster. If the in-series water heater is other than a Rheem continuous flow 874 series 20 or
26 or 27 litre in-series gas booster, then the references to the in-series gas booster in this guide may not be
applicable to the installation.
For information relating to the function and operation of the in-series water heater, refer to the Owner's Guide
and Installation Instructions supplied with the water heater.
