ABOUT YOUR WATER HEATER
MODEL TYPE
Congratulations for choosing a Solahart
®
water heater. Your Solahart Streamline closed circuit solar
water heater is designed for the solar collectors to be roof mounted and the solar storage tank to be
installed at ground or floor level. The solar storage tank is suitable for installation either outdoor or
indoor and with either Solahart ‘J’, ‘KF’, ‘LC’, ‘LCS’ or ‘BT’ solar collectors. The system is suitable for
installation in areas subject to frost or freeze conditions. Freeze conditions occur below 6
°
C.
This water heater is installed as a solar preheater to an in-series water heater. For information relating
to the function and operation of the in-series water heater, refer to the Owners Guide and Installation
Instructions supplied with the water heater.
HOW HOT SHOULD THE WATER BE?
The solar control unit will circulate the closed circuit fluid through
the solar collectors until a temperature of approximately 75
°
C is
reached in the solar storage tank. During periods of low solar
energy gain, the in-series booster water heater will boost the
water temperature automatically to its temperature setting when
required.

Solahart recommends the thermostat of the in-series booster
water heater be set at 60°C to maximise solar contribution.
Warning:
Temperature controllers
must not
be fitted to the
in-series booster water heater as part of a solar water heater
system because water at a temperature much higher than the
controller setting can be delivered.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater can deliver water at temperatures which can cause scalding. Check the water
temperature before use, such as when entering a shower or filling a bath or basin, to ensure it is
suitable for the application and will not cause scald injury.
We recommend and it may also be required by regulations that an approved temperature limiting
device be fitted into the hot water pipe work to the bathroom and ensuite when this water heater is
installed. This will keep the water temperature below 50
°
C at the bathroom and ensuite. The risk of
scald injury will be reduced and still allow hotter water to the kitchen and laundry.
WARNING
This water heater is only intended to be operated by persons who have the experience or the
knowledge and the capabilities to do so. This water heater is not intended to be operated by persons
with reduced physical, sensory or mental capabilities i.e. the infirm, or by children. Children should be
supervised to ensure they do not interfere with the water heater.
This water heater uses 240 V AC electrical power for operation of the control systems and the
electrically operated components. The removal of the front covers will expose 240 V wiring. They must
only be removed by an authorised or qualified person. The power lead from the water heater must be
plugged into a weatherproof electrical outlet if installed outdoors. Take care not to touch the power plug
with wet hands.
Care should be taken not to touch the pipe work connecting the solar storage tank and the solar
collectors. Very high temperature closed circuit fluid can be generated by the solar collectors under
certain conditions and flow through the pipe work from the solar collectors to the solar storage tank.
