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.
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.

COMMON FAULTS AND REMEDIES
Fault
No hot water flowing out
Water temperature
is not hot enough
Abnormal noise is
coming from the water
heater and pipelines
TPR Temperature and
Pressure Relief Valve is
discharging water
Failure of routine
The decision of whether to repair, replace or rework a faulty component is at the manufacturer's sole discretion.
Possible Causes
1) Cold water inlet supply to heater is closed.
2) Pipes are blocked
3) Water supply is cut off by Utility
1) Terminal block is damaged
2) Earth Leakage Circuit Breaker (ELCB) has operated
3) Element has failed
4) ECO has activated (Hi Limit)
5) Set temperature is too low
6) Thermostat is damaged
7) Water Heater is working
1) Heating up noise
2) Abnormal sound in pipeline when mains pressure is
not stable
3) Scaling on heater element
4) Water Hammer
1) Expansion of water during heating up
2) Valve is blocked by foreign materials
3) Excessive cold water pressure
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.
No warranty applies to the corrosion resistant heating unit,
supplied with this heater, when the chloride concentration of
the water supply exceeds 200ppm.
1) Turn on the inlet tap
2) Dredge the pipe by plumbers
