Thermann Owner’s Manual
80L to 400L Electric Storage Water Heaters
Electrical Connection
This water heater is designed for
single phase 240V A.C supply only.
The electrical connection must
comply with Local Supply Authority
Regulations and AS/NZS3000.
Connections are made at the terminal
block inside the water heater, and
a means for disconnection must be
incorporated in accordance with the
wiring rules.
Entry to the connection area is
through the hole beneath the electrical
cover, designed to accept a 20mm
conduit. The electrical cover may be
removed by undoing the two screws
on the cover and sliding the cover
downwards to disengage the top
edge. Ensure that the conduit entry
is well sealed to achieve correct
weatherproofing.
Note:
This water heater is fitted
with a thermostat and over-
temperature energy cut-out. Under
no circumstances should the water
heater be operated without both
these devices being in the circuit.
Replacement must be carried out
only by a licensed tradesperson or the
manufacturer.
Danger:
The operation of the thermal
cut-out indicates a possibly dangerous
situation. Do NOT reset the thermal
cutout until the water heater has been
serviced by a licensed tradesperson.
Caution:
Water heater must be filled
with water before turning on the
electricity supply.
Electrician:
Press the reset button
on thermostat to ensure over-
temperature cut-out is set.
When supply wiring has been
connected, supply wires must be kept
lower than the terminal block.
