Safety instructions

B In addition to the following instructions,
reading of the safety precautions provided in
the thermosyphon installation instructions is
strongly recommended.
Installation
B The following instructions are for the
installation of the electrical element for the
thermosyphon and respective electrical
connections. It is essential that all precautions
are taken to prevent electric shock hazard.
B Make sure that the electric power capacity in
the house is sufficient for the correct
operation of the heating element together
with the other household appliances already
in use.
B The installation should only be carried out by
a qualified technician.
B The installation should be carried out prior to
installation of tank on roof.
B The electrical connection should be done in
accordance with AS/NZS 3000:2007.
B First connect the water and only afterwards
connect to the electrical supply.
B The heating element should only be
connected to the electric current after the
installation has been concluded.
B Be aware that there is scalding risk and that
the roof may become slippery due to the hot
water which will escape from the tank when
removing the element.
B The power supply must be protected by an
individual circuit breaker at the main electrical
supply switchboard and rated to suit the
booster size. The supply to the solar water
heater can be operated directly from the
switchboard or via a remotely mounted switch
or time clock as requested by the customer.
The heater must be provided with a suitable
means for disconnecting the power supply.
