81333 v1.12 09.21 Tudor Installation Instruction
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.
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.
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.
NOTE: Failure to fit the recommended Restrictaflow valve will void the warranty
