SAFETY, WARNINGS, INSTALLATION NOTES
It is important you read the following safety and warnings information.
Safety and Warnings
•
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.
•
If the electrical conduit to the solar storage tank is damaged, it must be replaced by a qualified person in order to
avoid a hazard. Phone your nearest Solahart Dealer to arrange for an inspection.
•
This water heater uses 220 V - 240 V a.c. electrical power for operation of the electrically operated components. The
removal of the side cover will expose 220 V - 240 V a.c. wiring. It must only be removed by a qualified person.
•
This water heater is supplied with a thermostat, over-temperature cut-out, a combination temperature pressure relief
valve and an expansion control valve. These devices must not be tampered with or removed. The water heater must
not be operated unless each of these devices is fitted and is in working order.
The Solahart warranty may not cover faults if relief valves or other safety devices are tampered with or if the
installation is not in accordance with these instructions.
•
DANGER: The operation of the over-temperature cut-out on a thermostat indicates a possibly dangerous situation. If
the over-temperature cut-out operates, it must not be reset and the water heater must be serviced by a qualified person.
•
Do not touch any exposed pipe work or fittings connecting the solar storage tank and the solar collectors, as this may
result in a burn injury. Very high temperature hot water and in some circumstances high temperature steam can be
generated by the solar collectors under certain conditions and this flows through the pipe work from the solar
collectors to the solar storage tank.
Note: If in a trafficable location, any exposed pipe work or fittings in the collector circuit should be attended to and
covered with insulation. Phone your nearest Solahart Dealer to arrange for an inspection.
•
Do not remove the closed circuit relief valve on a closed circuit model as there may be a very high scalding risk
present. When operating in daylight, the heat exchange circuit will be pressurised and can contain superheated fluid
and may contain steam. At other times, the circuit may be pressurised and contain high temperature fluid.
•
Should the water from a closed circuit model appear blue or if blue closed circuit fluid is noticed around the base of
the water heater or solar collectors, this indicates a leak of the closed circuit fluid from the heat exchanger or the solar
collectors. The closed circuit fluid is non-toxic and not hazardous to health. Phone your nearest Solahart Dealer to
arrange for an inspection.
•
The water heater under normal use and summer solar conditions should heat the water in the solar storage tank to
60°C to 75°C. This water temperature can be exceeded and reach up to 95°C during periods of high solar radiation
conditions and reduced hot usage. During times of low solar energy gain or if boosting of the water temperature is
required, an electric heating unit will heat the water temperature to 60°C or up to 70°C depending upon the thermostat
setting.
Refer to
“Hotter Water Increases the Risk of Scald Injury”
on page 10.
•
For continued safety of this water heater it must be installed, operated and maintained in accordance with the Owner’s
Guide and Installation Instructions.
•
Servicing of a water heater must only be carried out by qualified personnel. Phone your nearest Solahart Dealer.
•
The lever on the temperature pressure relief valve and expansion control valve requires to be operated every six (6)
months to clear any deposits and to ensure the valve and its drain line are not blocked.
Refer to
“Relief Valves”
on page 7 and
“Minor Maintenance Every Six Months”
on page 18.
•
Only a person qualified to install or service a water heater can drain the water heater, if this is required.
•
Do not modify this water heater.
•
An open circuit system with an L, LF or LX tank does not have freeze protection. The system is not suitable for
installation in areas subject to frost or freeze conditions.
•
A closed circuit system with a J or F tank has protection against freezing and harsh water conditions. Refer to
“‘Hartgard’ Solution – Freeze Protection”
on page 10.
