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.
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.
