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.

INSTALLATION OF THE TPR VALVE
•The T&P Relief valve is supplied with the water heater. This
is to protect the heater from excessive pressure and
temperature.
•Seal the thread with the Teflon tape –never use hemp.
•Make certain the edge of the Teflon tape does not protrude
past the end of the thread. Screw the valve into the fitting
marked TPR and leave the valve outlet pointing down.
Tighten the valve using the spanner flats –not the valve
body.
•To minimise potential for scalding (particularly concerning
young children), a copper drain pipe must be fitted to the
TPR to carry the discharge away from the heater so that the
hot water discharged will not cause injury, damage or
nuisance. A drainpipe must be fitted for water discharge to a
floor waste trap (drain). The pipework from the TPR valve to
the floor waste trap should be as short as possible with no
restrictions.
•½” (15mm) OD copper pipe is recommended. The pipework
should have no more than three (3) right angle bends, in a
continuous downward direction, and installed in a frost-free
environment.
•DO NOT RESTRICT OR BLOCK THE OUTLET OF THE
DISCHARGE PIPE.
•It is normal for water to drip from the TPR discharge pipe
during a heat up cycle.
•Do not drill holes in the sides of this appliance. Any damage
caused by drilling will void the warranty.
•This pipe must be left open to the atmosphere. The valve or
drain valve outlet pipe must not be sealed or blocked.
FILLING THE WATER HEATER (by authorised person only)
•Open all hot water taps in the house, including the shower to
release air in the pipelines.
•Open the cold water inlet to the water heater.
•When water flows from each hot water tap without any
presence of air, it means that the heater is completely filled
with water. Close all hot water taps.
•Check all plumbing connections for leaks.
CONNECTION –ELECTRICAL (by authorised person only)
Warning! DO NOT turn on the electrical power supply to the
water heater until the water heater is completely filled with
water. There will be NO WARRANTY for dry firing of the
appliance.
•All electrical work and permanent wiring must be carried out
by a qualified person and in accordance with the wiring rules,
all local codes and regulatory authority requirements.
•The water heater shall be connected to single phase AC
supply and its rated power is 220-240V 50Hz. Refer to rating
label for input in wattage.
•The storage water heater must be permanently connected to
the electricity supply through a double poles linked switch
having a contact separation of at least 3mm in all poles
incorporated in the circuit and out of reach from the person
using the shower.
•Do not install this appliance near any possible contact with
water.
•DO NOT CONNECT THE WATER HEATER WITH A PLUG
AND SOCKET.
•The appliance must be earthed.
•All wiring must conform to local requirements. Ensure the
household connecting wire rating is capable of withstanding
the appliance load. If in doubt, please consult a qualified
electrician.
•For entry to the element cover remove ie two fixing screws.
Connect all ACTIVE and NEUTRAL wires as per the wiring
diagram provided on the inside of the element access cover.
Ensure the incoming EARTH wire is securely fixed to the
earth post provided in the heater case. Inspect and ensure
that all wiring links are secure prior to fixing the access cover
and turning the POWER on.
•The water heater must be completely filled with water prior to
connection with power.
•To ensure the Over-temperature and Energy Cutout is set,
press the Reset Button on the thermostat.
OPERATION
USING THE APPLIANCE
•It is recommended that the cold water tap always be turned
on first when there is water demand. Likewise, the hot water
tap always be closed first to avoid scalding.
•Mix the hot water with cold water by adjusting the taps to
your satisfactory requirement.
•When the electrical thermostat cuts off, the stored hot water
can still be drawn for use in the household. The water
heater will automatically cut in when the stored water
reaches a minimum set temperature.
•When the inlet water supply is interrupted, the main power
supply to the heater should be switched off to avoid dry
firing. Do not draw off hot water from the appliance to avoid
dry firing of an empty water heater.

longevity and avoid potential loss of warranty of this appliance.
ISOLATION OF THE WATER HEATER
The water heater should be switched off for servicing or if it is not
used for long periods of time (eg. vacation).
Isolate the water heater according to following steps:
•Isolate/switch off the electrical power supply to the
appliance.
•Close the cold water supply stopcock valve at the inlet of
heater –refer Diagram 3.
TEMPERATURE AND PRESSURE RELIEF (TPR) VALVE
•It is recommended that routine preventative maintenance is
carried out at least once every 6 months to remove lime
deposits and verify that the valve is operating correctly and
the discharge line is not blocked. Failure of routine
inspection may result in the water heater exploding.
•Continuous leakage of water from the valve may indicate
a problem with the water heater.
•To manually operate, carefully lift and release the lever
handle on the TPR valve to ensure the valve operates freely
and allow several litres of water to flush through the
discharge line. Ensure the discharge water is directed to the
floor drain. Avoid any contact with the discharge water to
avoid scalding.
•If there is no water flowing out, please contact a serviceman.
•Damage to the water heater due to blockage/restriction at
the overflow outlet will void the manufacturer’s warranty.
DRAINING THE HEATER AND TPR REPLACEMENT
Warning! Beware of high temperature water.
•First, disconnect all power to the water heater.
•Turn off the cold water supply to the heater.
•Release the pressure in the heater by carefully operating the
TPR valve release lever/knob.
•Undo the cold water inlet union. Attach a hose to the heater
side of the union. Drain the hose to waste.
•Operate the TPR valve release lever/knob allowing air into
the heater and water to drain via the hose.
•Remove and replace the TPR valve –beware of hot water.
•To fill heater refer to instruction “Filling the Water Heater”.
WATER QUALITY
•The vitreous enamel lined cylinder of the water heater is only
covered by the warranty when the total dissolved solids
(TDS) content in the water is less than 600 mg/L and black
colour coded magnesium anode (supplied with this heater) is
used.
•The use of an incorrect anode may shorten the life of the
water heater cylinder.
•The anode installed in this water heater will slowly dissipate
whilst protecting the cylinder. The life of the cylinder may be
extended by replacing the anode. For all water supplies, if
the anode is not replaced during a major 5 year service then
the maximum time after installation when the anode should
be replaced for this water heater is 8 years.
