Before You Begin
Refer to the mounting-hole template on page 17.
Read the installation and operating instructions completely.
Decide whether to install with concealed or exposed plumbing and/
or electrical connections. Concealed connections are preferred for
superior appearance.
Step 1 – Positioning
Position the heater so the tap will drain on to a draining board or
drip tray.
Position the base of the tap to be not less than 300 mm above the
draining board (height should be increased only if essential for
filling larger vessels).
Provide clearance for service access of not less than 100 mm top,
150 mm left, 20 mm right.
Mark corner positions for the heater on the wall so as to position
the paper mounting-hole template.
Step 2 – Fastening
Position mounting-hole template on wall and drill holes where
shown.
Remove cover fastening screws from heater and lift whole cover off
heater.
