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
The Rheem
®
Loline
®
open circuit solar water heater system is designed for the
solar collectors to be roof mounted and the vitreous enamel lined solar storage
tank to be remotely installed at ground of floor level. The solar storage tank is
suitable for either outdoor or indoor installation and can be installed with Rheem
NPT 200, HBT 200 / LCS or TBT 200 / CSA2007 solar collectors. This single
element model solar storage tank has only one front cover, located at the midpoint
of the tank.
The system has a level of freeze protection designed to guard the system against
damage from freeze conditions (refer to
on page 10). 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
on page 51).
Note:
The Rheem warranty against freeze damage applies only to systems
installed in Australia.
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.
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.
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 collector 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.
