General:
An electric element is installed in the storage
tank of the water heater to boost the water
temperature as required. The electric element
is controlled by a separate thermostat. The
thermostat is pre-set to 60°C and should not
be adjusted.
It may be connected to a continuous,
controlled load or off-peak tariff. Large users
of hot water may require connection to a
continuous tariff.
The electric booster is to be fixed wired to a
dedicated supply via an independent lockable
isolating switch.
The element and thermostat are 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.
Connections are made at the terminal block
under the water heater electrical cover.
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 cable 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 cable
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).
Excess
wire is not to be looped close to the
thermostat or tank.
When the supply wiring has been
connected, ensure the wires are kept
away from the inner tank, thermostats
and heating elements.
.
Replacing the Electrical Cover:
1. Press the reset button on the
thermostat to ensure the over-temperature
energy cut-out is set.
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.
5. Refit and tighten both screws in
the cover.
Ensure the water heater is filled with
water before turning on the electricity
supply.
