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 Hiline™ water heater is designed for both the solar collectors and the solar storage tank
to be roof mounted. The solar storage tank has a Colorbond jacket and is suitable for installation with Rheem
NPT 200 solar collectors.
The system does not have freeze protection. The system is not suitable for installation in areas subject to
frost or freeze conditions. Freeze conditions occur below 6°C. The system has NO WARRANTY for freeze
damage (refer to
"Terms of the Rheem Warranty"
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 this Guide will not be applicable to the installation. For information relating to the function and
operation of the in-series booster, refer to the Owners Guide and Installation Instructions supplied with the
booster water heater.
SOLAR OPERATION
The Rheem solar Hiline system has its vitreous enamel lined solar
storage tank installed on the roof directly coupled to the solar
collectors. It works on the simple scientific fact that hot water rises.
As the sun heats the water in the solar collectors, the increase in
temperature causes the water to rise through an insulated copper
pipe into the storage tank. This allows cooler water from the solar
storage tank to flow into the solar collectors to be heated by the
sun‟s energy. This process continues while solar energy is available
and until the water in the solar storage tank reaches a temperature
of approximately 75°C.
Automatic safety controls are fitted to the water heater to provide
safe and efficient operation.
SUNSTAT VALVE
The Sunstat valve limits the water temperature in the solar storage tank to a maximum of approximately
75°C. The valve:
Limits excessively high (scalding) water temperatures.
Reduces the discharge of hot water from the temperature pressure relief valve caused by high water
temperatures.
Prevents the over temperature energy cut out on the electric thermostat from activating unnecessarily.
