Before You Begin
Refer to the mounting-hole template on page 17.
Read the installation and operating instructions completely.

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.
Remove filter guide as shown in picture above.
Install plumbing and wiring and prepare pipe ends and wiring ends as
shown.
Screw heater chassis to the wall using screws or bolts suited to the wall.
