Important Safety Information
WARNING – THIS APPLIANCE MAY DELIVER WATER AT HIGH TEMPERATURE. REFER TO THE PLUMBING CODE OF AUSTRALIA (PCA), LOCAL REQUIREMENTS AND INSTALLATION INSTRUCTIONS TO DETERMINE IF ADDITIONAL DELIVERY TEMPERATURE CONTROL IS REQUIRED.
WARNING – FOR CONTINUED SAFETY OF THIS APPLIANCE IT MUST BE INSTALLED, OPERATED AND MAINTAINED IN ACCORDANCE WITH THE MANUFACTURER’S INSTRUCTIONS.
This water heater is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the water heater by a person responsible for their safety.
Children should be supervised to ensure they do not interfere with the water heater. Ensure animals are supervised so they do not interfere with the water heater.
DO NOT store chemicals or ammable materials, or spray aerosols near this water heater.
DO NOT modify this water heater.
DO NOT operate the water heater with any panels or covers removed.
If the water heater is not used for two weeks or more, a quantity of hydrogen (which is highly ammable) may accumulate inside the water heater tank.
To dissipate this gas safely it is
recommended that a hot tap be turned on for several minutes at a sink, basin or bath, but not a dishwasher, clothes washer or other appliance.
During this procedure there must be no smoking, open ame or any other electrical appliance operating nearby. If hydrogen is discharged through the tap it will probably make a sound similar to air escaping.
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 10 kW on 25L and 50L capacities.
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 drain line from the PTR Valve must be installed in a continuously downward direction in a frost free environment.
The PTR Valve is to be operated regularly to remove lime deposits and to verify it is not blocked. The drain line tted to the PTR Valve must be left open to the atmosphere.
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 valve may indicate a problem with the water heater.
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.

Owner’s Manual – Proflo 25/50 Litre Water Heater
Important Safety Information
It is normal for water to drip from the drain line tted 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 xed wiring in accordance with the Wiring Rules.
If the power supply cord is damaged, it must be replaced by the manufacturer, a service agent or a similarly qualied person in order to avoid a hazard.
Any electrical covers should be removed only by a licensed tradesperson, and only after the electrical supply to the water heater has been isolated.
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 tted 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 tted 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 800 kPa on 25L and 50L capacities.
Where the mains pressure can exceed or uctuate beyond this pressure, a pressure reducing valve must be tted in the cold water inlet supply.
Instructions explaining how the water heater can be drained can be found on page 5.
