MODEL TYPE

® ®
Your Rheem Loline open circuit solar water heater is designed for the solar collectors to be roof mounted
and the solar storage tank to be installed at ground level. The solar storage tank is suitable for either outdoor
or indoor installation and can be installed with Rheem NPT 200 or HBT 200 solar collectors. 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 "Freeze Protection"
solar hot and solar cold pipes insulated to offer protection against freeze damage (refer to
Insulation" on page 8). Freeze conditions occur below 6°C.
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 (refer to
Exclusions" on page 47). Note: 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.

SOLAR OPERATION

The Rheem Loline open circuit system has its vitreous enamel lined solar
storage tank installed at ground or floor level, remotely from the solar
collectors.
As the sun heats the water in the solar collectors the increase in
temperature activates the circulator. The circulator then moves the water
from the solar collectors through an insulated copper pipe to the solar
storage tank. The circulator switches on whenever the water in the solar
collectors is hotter than the water in the tank. Cooler water from the solar
storage tank is circulated to 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 70°C to 75°C.
Automatic safety controls are fitted to the water heater to provide safe and
efficient operation.
ELECTRIC BOOSTING
Water stored in the solar storage tank can be heated by an electric booster
heating unit. The booster heating unit is for heating the water at times of
low solar energy gain, such as during very cloudy or rainy weather, or
during the colder months. The Loline water heater is suitable for the
heating unit to be connected to either a continuous, or a time of use, or an
extended Off-Peak (overnight and day) or an Off-Peak (overnight)
electricity supply.
The booster heating unit is controlled by an electric thermostat. The thermostat and its over temperature
energy cut out are mounted on the solar storage tank behind the front cover. The water temperature is
automatically controlled to the thermostat setting when the booster heating unit is energised.
