FACTS YOU SHOULD KNOW ABOUT YOUR WATER HEATER
Water Heater Application
This water heater is designed for the purpose of heating potable water. Its use in an application other than this may shorten
its life.
Hotter Water Increases the Risk of Scald Injury
The temperature the system will achieve under solar heating depends on many factors, including the level of solar radiation
available, orientation and inclination of the solar collectors, incoming cold water temperature and volume of hot water
used.
Warning: This water heater can deliver water at temperatures which can cause scalding.
Under normal household use and average operating conditions, the system may achieve a water temperature of
approximately twice the maximum daily outside air temperature. In summer solar conditions this can be up to 60°C to
75°C. This water temperature can be exceeded and reach up to 95°C (see recommendation below). This can occur during
periods of higher solar radiation (particularly in summer) or during periods of reduced water usage. Extreme care should be
taken in these circumstances. These temperatures are sufficiently hot to cause severe scalding. Water at this temperature
may have been plumbed to fixtures where water hotter than 50°C is allowed, such as the kitchen and laundry.
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.
Precautions
The water heater must be maintained in accordance with the Owner’s Manual. Refer to “Water Supplies”
on page 16 and
“Maintenance Requirements”
on page 18.
If this water heater is to be used where an uninterrupted hot water supply is necessary for your application or business you
should ensure that you have back-up redundancy within the hot water system design. This should ensure the continuity of
hot water supply in the event that this water heater were to become inoperable for any reason. We recommend you seek
advice from your plumber or specifier about your needs and building back-up redundancy into your hot water supply
system.
Victorian Customers
Notice to Victorian Customers from the Victorian Plumbing Industry Commission. This water heater must be installed by a
licensed person as required by the Victorian Building Act 1993. Only a licensed person will give you a Compliance
Certificate, showing that the work complies with all the relevant Standards. Only a licensed person will have insurance
protecting their workmanship for 6 years. Make sure you use a licensed person to install this water heater and ask for your
Compliance Certificate.
‘Hartgard’ Solution – Freeze Protection
Solahart Closed Circuit Systems are protected against freezing or harsh water conditions by our exclusive ‘Hartgard’ fluid.
‘Hartgard’ is a blue, non-toxic, propylene glycol fluid which, when mixed with water, provides the Heat Transfer Fluid
contained in the solar collectors and the heat exchanger jacket around the tank. ‘Hartgard’ is used to lower the freezing
temperature of the Heat Transfer Fluid and so provides protection against freezing (Note: for the correct % of Hartgard in
the Heat Transfer Fluid, refer to the section on Frost / Freeze Protection). ‘Hartgard’ is a special food grade solution and is
the only solution permitted to be used in the closed circuit systems. Hartgard has been approved by the National Health and
Medical Research Council of Australia.
W arning : Should the water from your closed circuit series water heater appear blue, then this may indicate a leak of
‘Hartgard’ from the heat exchange jacket into the potable water.
Although
‘ Hartgard’ is of food-grade quality and not hazardous to health, the blue colour in the water does indicate a fault
and your Solahart dealer should be contacted to inspect the system.
