The PTR Valve should be checked by
a licensed tradesperson for adequate
performance, or replaced at intervals not
exceeding 5 years, or less in areas where
local regulations apply.
It is normal for water to drip from the drain
line fitted to the PTR Valve during heating
cycles.
Continuous leakage of water from the PTR
Valve may indicate a problem with the water
heater. This may be caused by excessive
water supply pressure, a faulty PTR Valve or
a faulty thermostat.
Turn off the water heater and contact Dux
After Sales and Service.
OVER-TEMPERATURE ENERGY
CUT-OUT:
The operation of the over-temperature
energy cut-out indicates a possibly
dangerous situation. Do NOT reset the over-
temperature energy cut-out until the water
heater has been serviced by a licensed
tradesperson.
ELECTRICAL SAFETY:
This water heater is designed for single
phase 230 - 240V a.c. supply only. The
electrical connection must comply with
Local Supply Authority Regulations and
AS/NZS 3000 (known as the Wiring
Rules). A means for disconnection must
be incorporated in the fixed wiring in
accordance with the Wiring Rules.
Any electrical covers should be removed
only by a licensed tradesperson, and only
after the electrical supply to the water heater
has been isolated.

Important Safety Information
When the supply wiring has been
connected, ensure the wires are kept
lower than the terminal block.
Excess wire is not to be looped close to the
thermostat or tank.
In addition to the Pressure & Temperature
Relief Valve, electric storage water heaters
are fitted with a combination thermostat and
over-temperature energy cut-out.
This device must not be tampered with
or removed. Replacement of this device
must only be carried out by a licensed
tradesperson or the manufacturer.
The water heater must not be operated
unless this device is fitted and in working
order.
COLD WATER CONNECTION:
The water heater is intended to be
permanently connected to the water supply
main, and not connected by a hose-set.
This water heater is designed for direct
connection to water supply pressures of
up to 1,120 kPa on 80L, 125L and 160L
capacities and 800 kPa on 135L, 180L,
250L, 300L, 315L and 400L capacities.
Where the mains pressure can exceed or
fluctuate beyond this pressure, a pressure
reducing valve must be fitted in the cold
water inlet supply.
Instructions explaining how the water heater
can be drained can be found on page 6.
