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 outdoor installation only and with
either Solahart ‘J’ or ‘KF’ solar collectors. The system is suitable for installation in areas subject to frost
or freeze conditions. Freeze conditions occur below 6
°C.
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 gas booster will boost the water temperature
automatically to a minimum 60°C when required.
Note: The preset outlet booster temperature setting of the gas
booster cannot be adjusted by the householder. The setting can
only be adjusted by your nearest Solahart Dealer. The preset
outlet booster temperature setting of the gas booster is 60
°C.
To meet the requirements of the National Plumbing Standard the
temperature setting must not be below 60
°C.
Warning: Temperature controllers must not be fitted to this
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.
This water heater has two outlets. One is a hot water outlet and the other is a tempered water outlet.
The purpose of the hot water outlet is to deliver hot water at between 60°C and 75°C, usually for
kitchen and laundry use. The purpose of the tempered water outlet is to deliver water up to 50°C,
usually for bathroom or ensuite use.
WARNING
This water heater is not intended to be operated, adjusted or tampered with by young children or infirm
persons. Young children should be supervised to ensure they do not interfere with the water heater.
The 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. 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.
