Read These Warnings First
Please read all installation requirements, installation procedures and
precautions before installing any Zenith Tudor water heater.
Never attempt to install any Zenith Tudor water heater without reading all of the
applicable instructions.
Zenith Tudor water heaters are open outlet (vented) water heaters and must not
be installed in the same way as mains pressure type water heaters.
The outlet from any Zenith Tudor water heater must be connected directly to an
outlet spout on the sink and must not be obstructed by a tap or valve or in any
other way.
The water flow is controlled by a cold water tap connected before the water
heater. Cold water pushes hot water out of the tank when the cold water tap is
turned ON. Any such cold water tap should be labelled HOT.
This water heater must not be connected to more than one outlet.
All plumbing connections must be made in accordance with AS3500.
The heater is intended only for indoor use and should never be installed
outdoors or be exposed to the elements of nature.
Over-sink and under-sink models are NOT interchangeable.
Children should be supervised to ensure they do not play with the heater.
The heater is unsuited for use by children or infirm people without supervision.
If the power supply cord is damaged it must be replaced by a Zenith Service
Provider or a qualified electrician.
Do not remove the cover of the heater under any circumstances without first
isolating the heater from the power supply.
Outlet temperature should never be set to less than 60°C without due regard to
regulations governing the storage temperature of hot water.

Installation Requirements
Before installing, ensure that the following are available:
a) sufficient space to position the heater so there is 270 mm clear access
under the heater (over-sink models) or 270mm above (under-sink).
b) standard 10 amp 240 volt power outlet within 1500 mm of the heater
c) cold water supply with a minimum working pressure of 50 kPa and a
maximum working pressure of 750 kPa.
If pressure may exceed 750 kPa, a pressure limiting valve must be installed.
Under-sink models must be installed beneath approved vented mixer taps
requiring a single mounting point on a sink, basin or tub.
Water pressure under 100 kPa may be sufficient for over-sink heaters but may
not operate under-sink mixer taps satisfactorily.
Before installing, ensure that the following are available:
Installation Procedure
Step One - Tapware
Over-sink models must be installed with an inlet valve to control the flow from
the water supply to the heater. No valve is supplied with the heater. The water
supply and valve should be connected after the fastening the heater to the wall.
Over-sink models are supplied with a 300 mm swivel spout. An 300 mm to

600 mm telescopic swivel spout (99032) is available as an optional extra.
Under-sink models must be installed with approved vented tapware. It is
advisable to fit the tap to the sink before mounting the heater to the wall
beneath the sink.
1. Ensure that the flexible tubes are firmly attached to the base of the tap body.
2. Flush water supply pipes thoroughly to remove any silt or fines.
3. Fasten the tap body to the sink using the bolt & plate system provided.
4. Connect red flexible tube (from tap base "C") to the heater outlet.
5. Insert flow restrictor provided to the free end of blue flexible tube "A"
ONLY IF the water pressure is likely to exceed 250 kPa. Otherwise discard
restrictor.
6. Connect blue flexible tube (from tap base "B" ) to the heater inlet.
7. Connect blue flexible tube (from tap base "A") to the cold water supply.

instructions on page 7. Such adjustments should be made only by a qualified
technician.
Note: If replacing an existing open outlet (vented) water heater an isolation valve
must be fitted to the incoming water supply and a 7L/min flow restrictor fitted
at the isolation valve outlet. It is essential to establish that any existing tapware
is vented.

Over-sink heaters should be installed so that the outlet spout drains to a sink
or basin, and with a clearance of 270 mm beneath the heater to allow for
service access.
Under-sink heaters should be installed a closely as possible to directly below
the outlet tap with a clearance of 270 mm above the heater.
Step Three - Fastening
It is not necessary to remove the case of the heater during installation.
The heater must be wall mounted with two fixing screws as shown in the
diagram on page 5. Fixing screws must have the strength to support the filled
heater.
The fixing screws are to protrude 4 mm from the wall as shown in the diagram
on page 5 so as to fit into keyhole slots provided on the rear of the heater.
Step Four - Connecting
On over-sink models, the inlet and outlet are located on the base of the heater.
On under-sink models, the inlet and outlet are located on the top of the heater.
All Zenith Tudor water connections are via 15 mm compression fittings and must
be made strictly as shown in the diagrams.
Over-sink models are supplied with a 300 mm open outlet spout, and must
also be fitted with an isolation valve on the cold water side. A valve is not
supplied with the heater and must be supplied and fitted by the installer.
Under-sink models must be installed with approved vented tapware regulating
the incoming water supply which displaces the hot water from the heater so it
discharges through the open vented spout incorporated into the tap mounted
on the basin or sink.
The use of tapware other than approved vented tapware is dangerous.
Each heater is equipped with a 1600 mm power cord and plug and should be
connected to a standard 10 amp power outlet located adjacent to the heater.
Do not turn the power ON until the heater is filled with water and air is purged
from the heater.
Step Five - Commissioning
Fill the heater tank and purge air from the heater by turning the water supply
ON and running water through the heater until it flows smoothly. Turn the water
supply OFF and turn the power supply ON. The heater will then run through its
heating cycle.
During the heating cycle, drips fall from the delivery spout or tap.
Dripping will cease when the heating cycle is completed and the stored water
temperature has reached the level set by the user.

Operating Procedures
Water Temperature
Zenith Tudor water heaters are fully automatic, and may be left switched ON
under the control of the variable thermostat.
Nominal operating temperature can be varied from about 30°C to about 80°C.
Temperature should not be set to less than 60°C without due regard to
regulations governing the storage temperature of hot water.
Economy Setting
ANTIFREEZE
LOW
OFF
ECONOMY
HIGH
The economy setting "E" will maintain stored water temperature at
approximately 60°C. At the "E" setting, the temperature control locates into a
set position and a slight resistance will be felt when rotating the temperature
control beyond that setting. This measure is to help ensure that higher
temperatures are only selected deliberately.
Frost Protection
If the heater is located where ambient air temperature could fall below 5°C
when the heater is not in use, the "anti freeze" setting on the temperature
control will maintain stored water temperature over 5°C to prevent freezing
and damage to the water heater.
The same protection does not extend to connecting pipework or fittings.
Safety Cutout
Should the heater over-heat, a manually resettable safety cutout will
automatically turn the heating element OFF. The cutout must be reset by a Zenith
Service Provider or a licensed electrician. Users should never reset the cutout
without qualified assistance.
Cleaning
Never use strong, corrosive or abrasive cleaning materials. Wipe clean the
outer surfaces with a sponge or soft cloth using a mild soap and water.
Domestic dish washing liquid detergent is most suitable.
