SAFETY
•
This appliance 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
the safe use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that
they do not play with the appliance.
•
CAUTION: In order to avoid a hazard due to inadvertent
resetting of the thermal cutout, this appliance must not be
supplied through an external switching device, such as a
timer, or connected to a circuit that is regularly switched on
and off by an appliance or utility.
•
The water heater must have provision for drainage in the
event that the water heater leaks or connection pipes break.
•
The water heater is rated 220-240V/50Hz AC, single phase.
•
The installation of the Electrical power supply cable must be
correctly sized to safely carry the maximum current draw of
the appliance. Ensure all earth wires and connections are
separated from the neutral circuit.
•
Ensure that the electrical connections are undertaken by a
qualified electrician complying with Local Code of Practice.
•
Power must not be turned on until the water heater is filled
with water. Open all hot water taps/faucets to release
trapped air until only water is discharged.
•
Temperature over 50°C may cause scalding. Please mix
cold water with hot water to obtain the right bathing
temperature.
•
Please operate the Temperature and Pressure Relief Valve
(TPR) manually at least once every 6 months to remove lime
deposits and verify that the drain pipe from the valve is not
blocked.
•
Power must be turned off before any service and
maintenance work can commence. All work must be
performed by a qualified technician.
•
For replacement of parts, please use original parts from
manufacturer. Use of non-approved parts will result in a void
the manufacturer’s warranty.
•
Water may drip from the discharge pipe of the TPR valve
during normal expansion. The discharge pipe should be left
open to the atmosphere preferably 150 mm above the
nearest floor trap. On no accounts must the drain pipe be
plugged. Blockage of the TPR discharge pipe may cause
serious damage and
will void the manufacturer’s warranty.
Warning
– Scalds Minimisation. To minimise scalding,
especially for those people in high risk categories ie. Young
children, people with incapacitating medical conditions,
elderly people, etc, this unit must be installed in accordance
with all local and government regulations, and the use of
secondary devices such as a suitable tempering valve or
anti-scald water shut-off valve. (If a tempering valve is used,
refer to its servicing instructions for periodic maintenance.)
•
Hot water must be stored at a minimum of 60°C to inhibit the
growth of Legionella bacteria.
•
All sanitary outlets used primarily for personal hygiene shall
deliver hot water not exceeding: a). 45°C for early childhood
centres, primary and secondary schools and nursing homes
or similar facilities for young, aged, sick or disabled persons;
and b). 50°C in all other buildings.
INSTALLATION AND CONNECTION
(by authorised person)
CHOOSING WHERE TO INSTALL
•
The water heater must be installed indoors.
•
The wall must be strong enough to support the water heater
filled with water using the universal mounting brackets and
masonry anchors provided.
•
The heater should be installed as near to the point of use as
possible.
•
Ensure that sufficient and safe space is available for
servicing of the water heater to both adjacent wall and/or
ceiling for access to the element, sacrificial anode and
Temperature and Pressure Relief Valve.
•
Leave adequate clearance beside the appliance (preferably
the length of the water heater), for inspection or service of
the anode through the case lid. If inadequate room is
available then the appliance may have to be disconnected
and removed for service.
•
There must be a floor trap near installation point for safe
discharge of the Temperature and Pressure Relief Valve.
•
The water heater, electrical connections, and electric
leakage protector should be protected against any contact or
splashing water.
INSTALLATION OF THE WATER HEATER
•
Fasten the mounting bracket to the upper holes in the back
of Water Heater with two (2x) M10 bolts and washers
provided in the loose parts kit.
•
Fasten the plastic lower wall spacer to the lower holes in the
back of Water Heater with the two (2x) self tapping screws
provided.
•
Locate the drilling position for the masonry anchor bolts on
the wall, as shown in Diagram 2. The holes must be in the
same horizontal line.
•
Drill holes in the wall, and then insert the two (2x) masonry
anchor bolts complete with nuts.
•
Hang up the water heater on the wall and tighten the anchor
bolts to the wall mounting bracket.

CONNECTION
– PLUMBING
▪
Pipe Material :
The pipes connecting to the inlet and outlet of the water
heater must be strong enough to withstand water pressure
up to 1.40 MPa
. The storage water heater must be
permanently connected to the water mains, hose set is
not recommended to be used.
▪
Pipe Size :
¾” (20mm) OD copper pipes are to be used for cold water
inlet and hot water outlet
– refer to Diagram 3.
It is the responsibility of the installer to ensure all pipework &
fittings are correctly lagged and do not leak.
▪
Connection :
Water connections are located at the side of the heater. Heat
must not be applied at these connections as it can damage
the internal water tubes of the appliance
– refer to Diagram
4
.
Both the inlet and outlet water connections are located at the
side of the water heater, with the upper connection being outlet
and lower connection being inlet. The cold water tap is fitted to
the inlet as shown in Diagram 3. As the temperature is high at
the outlet, a mixing valve which mixes hot water with cold
water is suggested to be fitted. If the outlet tap is not close to
the water heater, thermal insulation material is recommended
to insulate the hot water pipe in order to reduce heat loss.
