SAFETY, WARNINGS, INSTALLATION NOTES
It is important you read the following Safety and Warnings, and Relief Valves information.
If the solar water heater is installed with an in-series booster water heater, it is also important you read the
Safety and Warnings, and Relief Valves information relating to the function and operation of the in-series water
heater. Refer to the Owner’s Guide and Installation Instructions supplied with the in-series water heater.
SAFETY AND WARNINGS
•The circulator will operate whilst suitable solar conditions are available until water in the solar storage tank
is heated to 70°C to 75°C during normal operation. Water temperature of up to 75°C to 80°C could be
reached during over-temperature operation.
During times of low solar energy gain and boosting of the water temperature is required, the electric
heating unit will heat the water temperature to 60°C or up to 70°C depending upon the thermostat setting.
If this water heater is installed with an in-series booster water heater, then this temperature can be 70°C
or higher if the booster water heater is a continuous flow gas booster or 60°C or higher is the booster
water heater is a storage water heater.
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.
Refer to:
▪“Solar Operation” on page 10, and
▪“How Hot Should the Water Be?” on page 12, and
▪“Hotter Water Increases the Risk of Scald Injury” on page 13, and
▪“Temperature Adjustment” on page 13.
•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 or play with or at the water heater.
•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: 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.
•If the power supply cord or plug to the solar control unit or the electrical conduit to the solar storage tank
is damaged, it must be replaced by a qualified person in order to avoid a hazard. The power supply cord
and plug must be replaced with a genuine replacement part available from Solahart. Phone your nearest
Solahart Dealer to arrange for an inspection.
•The power lead from the solar controller must be plugged into a weatherproof electrical outlet if installed
outdoors. Take care not to touch the power plug with wet hands.
•This water heater uses 220 V - 240 V a.c. electrical power for operation of the control systems and the
electrically operated components. The removal of the front cover or solar control unit cover will expose
220 V - 240 V a.c. wiring. They must only be removed by a qualified person. Do not operate the water
heater with any of the covers removed.
•This water heater is supplied with a thermostat, over-temperature cut-out, temperature sensors and a
combination temperature pressure relief 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.
