Installation Procedure
continued
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 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. When
correctly installed the plug must be accessible.
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.

Retrofit instructions for open vented heaters
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 6ltr/min (Max.), must be
fitted to the outlet side of the isolating tap. (See diag 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
