ABOUT YOUR WATER HEATER
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.
MODEL TYPE
Your Rheem
®
solar Loline water heater is designed for the solar collector(s) to be roof mounted and the
vitreous enamel lined solar storage tank to be installed at ground or floor level, remotely from the solar
collector(s). The solar storage tank is suitable for installation either outdoor or indoor and with 1 x CSA2612 or
1 or 2 x LCS or 1 or 2 x NPT200 solar collector(s). If an in-series gas booster is mounted to the solar storage
tank, then it is suitable for outdoor installation only.
The system is not suitable for installation above 400 metres altitude.
The system has a level of freeze protection designed to guard the system against
damage from freeze conditions (refer to
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 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
on page 58).
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.
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.
MAINS PRESSURE
The water heater is designed to operate at mains pressure by connecting directly to the mains water supply.
If the mains supply pressure in your area exceeds that
25, a pressure limiting valve must be
fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
A minimum water supply pressure of 200 kPa is required to enable the solar circulator and solar circuit system
to operate effectively.
SOLAR OPERATION
The operation of the circulator is controlled by the combination of:
the hot sensor located at the outlet of the solar collectors.
The hot sensor measures the water temperature at the outlet of the solar collectors.
the cold sensor located at the solar cold outlet at the base of the solar storage tank
The cold sensor measures the water temperature at the bottom of the solar storage tank.
the differential controller located in the solar control unit.
