INSTALLER TO ISSUE A PLUMBING CERTIFICATE OF COMPLIANCE
This water heater must be fitted with the supplied TP VALVE before installation.
Always fit this water heater with a PRESSURE CONTROL VALVE and EXPANSION
CONTROL VALVE (which may be combined in one unit) not exceeding the kPa rating
of the water heater as stated on the serial label. TP VALVE and EXPANSION VALVE
overflow pipes must be led separately to the outside of the building in a continuous
downward direction, in a frost free ambient with the outlets being left open to the
atmosphere, and in case of the TP VALVE must be copper. The EXPANSION VALVE is
designed to drip under normal operating conditions and must never be plugged.
1. Flush the cold water supply line prior to connecting.
2. Check that the control valve is free from dirt.
3. Ensure all piping and water heater brackets are securely fixed.
4. After connecting the installation, open one or more hot water taps and
open the cold water to dispel air from the system.
5. Close all hot taps to bring water heater under pressure.
6. Check all plumbing connections for leaks.
7. Installation diagrams must be complied with in all respects.
8. The installation of a drip tray is required where water leaking from the

MAINTENANCE INSTRUCTIONS
SWITCH OFF ELECTRICAL SUPPLY BEFORE ATTEMPTING ANY MAINTENANCE OR
REPAIRS ON THE WATER HEATER
REPLACEMENT OF THERMOSTAT
1. Disconnect wiring, remove thermostat by pulling it out of it's pocket.
2. Fit new thermostat, ensuring the stem of the thermostat is not bent or damaged in any
way. On electronic models, ensure that the metallic thermostat bulb is inserted before
the wired probe.
3. Reconnect wiring to thermostat ensuring connections are clean, tight and secure.
4. Set thermostat to 60˚C or as required by user.
REPLACEMENT OF ELEMENT
1. Drain water from the water heater.
2. Remove thermostat as above and remove flange lid from cylinder.
3. Remove old element and gasket from flange lid.
4. Fit new element and gasket to flange lid.
5. Refit flange lid, and replace thermostat as above.
REPLACEMENT OF ANODE
1. The magnesium anode installed in a vitreous enamel lined steel water heater will
slowly dissipate whilst protecting the cylinder.
2. The life of the cylinder may be extended by replacing the anode.
3. Inspect the anode yearly, and if required, replace the anode.
4. Replacement of the anode should be carried out at minimum 2 year intervals, during the
warranty period, to ensure protection of the steel cylinder.
5. The life expectancy of the anode would be dependent on the water quality in the area,
which the water authority can advise on.
6. A guideline below ( as reference only):
TOTAL DISSOLVED SOLIDS RECOMMENDED
PPM REPLACEMENT
0 - 400 3 Years
400 - 600 2 Years
Over 600 1
Year
Fitment of an aluminium anode is recommended for harsh water conditions.
7. When water is supplied from a borehole or well, anodes should be replaced at least
once a year.
8. Replace anode as follows:
(a) Drain water heater.
(b) Remove anode cover and unscrew anode from cylinder.
(c) Fit new anode and replace anode cover.
THE ANODE IS A MAINTAINABLE COMPONENT
