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.  
SOLO MIXER  
HERO MIXER  
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.

Do not dismantle the assembled tap body during installation. Mixer taps are  
factory tested and sealed to provide optimum performance.

To adjust water temperature delivered by Solo and Hero mixer taps, see  
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.

Installation Procedure continued  
Step Two - Positioning  
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.

Ten Litre  
under-sink 4.0

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  
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.  
LOW  
ECONOMY  
ANTI-  
FREEZE  
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.  
HIGH  
OFF  
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.

Disconnect from power and turn water supply OFF before attempting any kind  
of service work.  
Removing the case  
1. Remove temperature control knob by gripping it and pulling towards you.  
2. Remove the single retaining screw located beneath the temperature control knob.  
3. Remove the four case screws two at top, two at bottom.  
4. The case can now be lifted off carefully.  
Replacing the case  
Reverse of the above procedure.  
Replacing a thermostat  
Knob removed to show screw  
1. Remove the front cover.  
2. Disconnect the two electrical terminals from the thermostat. These are  
spade connectors and can be easily pulled off.  
3. Remove the two screws attaching the thermostat to the plastic upright.  
4. Pull the capillary out of the thermostat pocket located on the element  
assembly.  
5. Take the new thermostat (Z90421) and uncoil about half of the capillary tube.  
6. Push the new capillary into the pocket ensuring that:  
a) if it is an over sink model, the cutout bulb goes in first then the  
thermostat bulb behind it.  
b) if it is a under sink model, then the reverse is applicable.  
Thermostat spade connectors  
Attach the thermostat to the plastic upright.  
Reconnect the two electrical terminals. It does not matter which way around  
the connections occur.  
Ensure the remaining capillary coil is out of the way of any live terminals.  
Ensure the plastic upright is located securely in the position provided.  
Refit the cover assembly.

Tap Temperature Adjustment  
Adjustment of a tap temperature limiter on Solo and Hero vented taps  
should be made only by a Zenith Service Provider or a qualified  
technician.  
Top Ring “X”  
1. Remove tap handle assembly to expose the mixer cartridge.  
2. Lift and rotate the serrated top ring "X" from the mixer cartridge "Y".  
Rotating the ring left or right will regulate the water temperature.  
Rotating the ring clockwise will increase the water temperature.  
Rotating the ring anticlockwise will decrease water temperature.  
The tap normally operates with the ring in the central position.  
3. Reassemble the tap handle assembly to its original condition.  
4. Test the temperature of the water outlet to check acceptability.
