General:
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/NZS 3000.
Connection of the electrical wiring
must only be carried out by a licensed
tradesperson.
The fuse or circuit breaker protecting the
supply to the water heater must have a
rating of at least 10 amps.
The water heater must not be connected
to an off peak tariff. It should be
connected to a continuous supply tariff
or a suitable controlled load tariff (such as
Tariff 33 in Queensland). Contact Dux After
Sales and Service if required.
The water heater is designed to be
permanently connected to fixed wiring.
A set of terminals and a conduit entry is
provided for this purpose.
Connections are to be made at the terminal
block under the water heater electrical
cover. A means for disconnection must
be incorporated in the fixed wiring in
accordance with the Wiring Rules.
Removing the Electrical Cover:
Before removing the electrical cover,
ensure the electrical power supply is safely
isolated.
The electrical cover is removed by
undoing the two screws at the bottom
of the cover and sliding the cover
downwards to disengage the top edge.
Connections:
The conduit entry is a pre-punched hole
designed to accept a 20 mm conduit
gland. It is located adjacent to the terminal
block.
To prevent damage to the wiring, the
conduit entry must be fitted with a gland
prior to feeding the wiring through the
hole. Ensure the conduit entry is sealed
correctly.
Connect the active and neutral wires to
the terminal block and the earth wire to
the earth tab (located on the right hand
side).
Replacing the Electrical Cover:
1. Check the Pressure & Temperature
Relief Valve, both of the brass plugs,
and their clear plastic packaging have
been removed from inside the cover.
2. Ensure the terminal block mounting
plate is horizontal.
3. Slide the cover up, ensuring the top
edge engages under the case.
4. Swing the cover down until the
bottom edge contacts the case.
Ensure the terminal block mounting
plate is below the pins located inside
the cover.
5. Refit and tighten both screws in the
cover.
Ensure the water heater is filled
with water before turning on the
electricity supply.
