WARNING
Please read all installation requirements, installation procedures and
precautions before installing any Zip Tudor water heater.
Never attempt to install the appliance without reading all of the applicable
instructions.
For continued safety of this appliance it must be installed, operated and
maintained in accordance with the manufacturer’s instructions.
This appliance may deliver water at high temperature. Refer to the plumbing
code of Australia (PCA), local requirements and installation instructions to
determine if additional delivery temperature control is required.
The appliance is recommended for sinks and tubs; not recommended for basins.
Zip 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 Zip 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 appliance 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.
The appliance is unsuited for use by children or infirm people or those
without experience;
unless they have been given supervision or instruction by a person responsible
for their safety. Children should be supervised to ensure they do not play
with the heater.
If the power supply cord is damaged it must be replaced by a Zip 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.
Do not turn the power ON unless the appliance is filled with water.
Outlet temperature should be set to no greater than 50°C without due regard to
regulations governing the storage temperature of hot water.
The appliance must not be cleaned by a water jet.
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 100 kPa and a maximum
working pressure of 350 kPa.
d) Isolating valve (not supplied)
If the pressure may exceed 350 kPa, a 350kPa pressure limiting valve (not
supplied) must be installed in the cold water supply line.
A double check valve (not supplied) is required to comply with the backflow
requirements of AS/NZS3500.1
Under-sink models must be installed beneath approved vented mixer taps
requiring a single mounting point on a sink, or tub. (Not recommended for
basins).
Installation
NOTE: Failure to correctly fit the Restrictaflow valve (provided) will
void the warranty
Step One – Tapware
Note: Instructions for correct assembly and installation of Tudor tapware is
included in the tapware box. Pay close attention to these instructions.
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.
- Install the Restrictaflow valve provided, with the isolating valve (not supplied), into the main cold water supply line. The Restrictaflow is adjustable and must be set to deliver no more than 6Ltr/min (Max.) NOTE: Do not fit the Restrictaflow valve to the tank (See P.5 diag)
- Flush water supply pipes thoroughly to remove any silt or fines.
- Fasten the tap body to the sink using the bolt & plate system provided.
- The hose with a WHITE band on it connects to the tap hole with NO marking.
- The hose with a RED band on it connects to the tap hole with a RED marking.
- The hose with a BLUE band on it connects to the tap hole with a BLUE marking.
- Ensure that the flexible tubes are firmly attached to the base of the tap body and in the correct sequence. Refer tapware installation sheet.
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.
Step Two – Positioning
Water heaters should be installed as closely as possible or directly below the
outlet tap, with a clearance of 270 mm above the heater.
This unit must not be positioned in an area that may be cleaned by a water
jet.
Step Three – Fastening
| Model | Weight (kg) |
|---|---|
| Empty | Full |
| 5 Litre under-sink | 3.5 |
| 10 Litre under-sink | 4 |
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
The inlet and outlet water connections are located on the top of the heater.
All Zip Tudor water connections are via 15 mm compression fittings and must be
made strictly as shown in the diagrams. The inlet and outlet connections
located on top of the heater are 3/8”BSP (10mm).
The connections from your chosen Tudor tap are 1/2” BSP (15mm) compression
fittings. The supplied 3/8” to 1/2” adaptors will be required to be fitted to
the inlet and outlet on the heater before connecting the tap.
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 sink or tub.
The use of tapware other than approved vented tapware may result in
pressurising the heater water tank, causing damage.
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.
When correctly installed the plug must be accessible.
NOTE: 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 “hot” mixer tap, until water 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.
Retrofit instructions for open vented heaters
NOTE: Failure to fit the recommended Restrictaflow valve will void the
warranty
Flow restrictor
If replacing an existing open vented water heater, an isolating valve must be
fitted to the incoming water supply. A Restrictaflow valve set at 6
litres/minute (maximum), must be fitted to the outlet side of the isolating
tap (see diagram on page 5).
NOTE
- It is essential that the tapware is the “Open Vented” type.
- If the aerator on the end of the tap is too restrictive, it must be removed.
- The installation requirements from page 2 are also applicable.

Operation **
**
Control Panel
Water Temperature
Zip 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 50°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 50°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 Cut-out
Should the heater over-heat, a manually resettable safety cut-out will
automatically turn the heating element OFF. The cut-out must be reset by a Zip
Service Provider or a licensed electrician. Users should never reset the cut-
out without qualified assistance.
