GENERAL INSTALLATION INSTRUCTIONS
HOT WATER DELIVERY TEMPERATURE
Local regulations and or the requirements of AS/NZS 3500.4 must be considered regarding the
temperature limitations of hot water supplied to areas used primarily for personal hygiene. The
temperature of water to these areas may be limited to 50º C or less. To ensure these regulations and
or requirements are met the system MUST be installed in accordance with the 'Water Heater and
Controller Installation Configurations' Section of these instructions.
WATER HEATER AND CONTROLLER INSTALLATION CONFIGURATIONS
If the appliance is marked to state that it delivers water not exceeding 50°C, local regulations may
permit it's installation without a Temperature Limiting Device. Installations without a Temperature
Limiting Device are shown in Diagram 1 (page 15). If you are unsure about your local regulations
contact your regulating authority or Dux.
If the appliance is NOT marked to state that it delivers water not exceeding 50°C, or your local
regulations require installation with a Temperature Limiting Device then install the appliance in
accordance with Diagram 2 (page 15).
Ensure that suitable fixing screws or bolts are used to secure the units to the wall, in accordance with
AS/NZS 5601 Section 5. Wooden plugs shall not be used.
The top bracket has a keyhole slot so that the appliance can be positioned by hanging it on one screw,
then the other screws can be secured.
SERVICE CONNECTION POINTS
See Table 1 for individual appliance connection / fitting dimensions. Note that these dimensions are
NOT an indication of the pipe sizes required.
An Approved full flow isolation valve and disconnection union MUST be fitted to the cold water inlet.
A non return valve is not required unless required by local regulations.
Isolation Valves must not be fitted directly to the appliance.
If may be necessary to fit a temperature limiting device for delivery to areas used primarily for the
purposes of personal hygiene. Refer to the ‘Water Heater and Controllers Installation Configurations’
Section of this document.
MOUNTING THE APPLIANCE
See Table 1, page 17 for individual appliance weights. The wall or structure on which the units are
to be mounted must be capable of supporting these weights and the associated pipe-work.
The top bracket has a keyhole slot so that the appliance can be positioned by hanging it on one
screw, then the other screws can be secured.
The appliance can be mounted directly against the wall or structure. There is no need to use, non
combustible sheeting or leave an air gap between the appliance back panel and the wall or structure
for the purposes of meeting the temperature hazard requirements of AS/NZS 5601.
If the appliance is to deliver water primarily for the purposes of personal hygiene in an
early childhood centre, primary or secondary school, nursing home or a similar facility
for the care of young, aged, sick or disabled persons as defined in AS/NZ 3500.4 a
Temperature Limiting Device (TLD), such as a Tempering Valve may be required even
if the appliance is set to 50º C or less.
