Installing the appliance
1. Remove the appliance cover by first
removing the fascia panel then
unscrewing the fixing screw.
2. If the power supply cable is to be
connected in the upper part of the
appliance follow instructions 1 to 3
for “Electrical Connection From
Above” on page 11.
3. Place the appliance on the wall
bracket with the threaded stud
through the fixing hole in the back
plate. If necessary the threaded
stud can be carefully bent through
a maximum of approximately 30°
to allow it to align with the fixing
hole (see Fig 4). However, it must
be ensured that that the water
connection pipes can be connected
to the appliance without applying
force.
4. Screw the two
3

appliance’s water connection pipes,
each fitted with a
3

fittings.
5. Screw the plastic knurled retaining
nut onto the threaded stud of the
wall bracket.
6. Open the water supply to the
appliance and slowly open the
shut-off valve (see Fig 5) in the
cold water connection piece to
position 1. Check all connections
for leaks.
7. Ensure that all air is eliminated
from the water heater by opening
and closing the hot water tap until
no more air emerges.
