Important Safety Information
Relief Valve:
The Pressure & Temperature Relief (PTR)
Valve must be installed directly into the
RP½”(DN15) socket marked “RELIEF
VALVE”.
The PTR Valve rating is 1,000 kPa and is
also shown on the compliance plate.
The valve must not be tampered with or
removed. The water heater must not be
operated unless this valve is tted and in
working order.
The PTR Valve should be checked by
a licensed tradesperson for adequate
performance, or replaced at intervals not
exceeding ve years, or less in areas where
local regulations apply.
The PTR Valve is to be operated regularly to
remove lime deposits and to verify it is not
blocked.
DANGER – FAILURE TO OPERATE
THE PTR VALVE EASING LEVER AT
LEAST ONCE EVERY SIX MONTHS
MAY RESULT IN THE WATER HEATER
EXPLODING.
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.
Relief Valve Discharge Pipe:
The discharge pipe connected to the PTR
Valve is to be installed in a continuously
downward direction and in a frost-free
environment.
It is normal for water to drip from the
discharge pipe of the PTR Valve during
heating cycles. The discharge pipe must be
left open to be atmosphere.
Permanent Water Connection:
The water heater is intended to be
permanently connected to the water supply
main, and not connected by a hose-set.
Water Supply Pressure:
This water heater is designed for direct
connection to water supply pressures of up
to 800 kPa.
Where the mains pressure can exceed or
uctuate beyond this pressure, a pressure
reducing valve must be tted in the cold
water inlet supply.
Temperature Protection:
Water heaters can produce very hot water.
To reduce the risk of scald injury, it is
mandatory that an approved temperature
control device (such as a tempering valve)
is tted to the hot water supply to outlets
used primarily for the purposes of personal
hygiene. This device should be checked at
regular intervals to ensure its operation and

Introduction
General:
This Owner’s Manual applies to the Dux
Ecosmart range of Electric and Gas Boosted
Solar Water Heaters.
Electric Boosted Solar Water Heaters:
Solar water heaters heat water by pumping it
through the solar collectors when conditions
are suitable.
During the winter months or when it is
cloudy, there may not be enough solar
energy gain available to heat the required
quantity of water. 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 plumbing and electrical connections to
the solar collectors are the same for both
electric and gas boosted models. The hot
water plumbing connection and the electrical
connection to the boost element are specic
to the electric boosted models.
Throughout this manual, most pages are
common to both electric and gas boosted
models while some pages are specic to
electric boosted models. Those pages that
are specic to electric boosted models are
clearly identied.

Solar water heaters heat water by pumping it
through the solar collectors when conditions
are suitable.
During the winter months or when it is
cloudy, there may not be enough solar
energy gain available to heat the required
quantity of water. An instantaneous gas
water heater is installed between the storage
tank of the water heater and the hot water
outlets to boost the water temperature as
required. The instantaneous gas water heater
is controlled separately.
The plumbing and electrical connections to
the solar collectors are the same for both gas
and electric boosted models. The hot water
plumbing connection and the gas connection
to the instantaneous water heater are specic
to the gas boosted models.
