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 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 250L, 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 5.
