3.3.3 Wall fitting
The product is designed to be mounted on a wall.
When the insulation cap is removed, there is easy
access to the screw holes (D).
The Nano is attached to the wall with the sup-
plied fastening metal band (V); see illustration.
The metal band is bent/placed around the mid-
dle of the tank and fixed to the wall through the
holes in the insulation, using the screws/washers
supplied. Ensure that the connectors do not press
on the insulation parts. Use a torx type bit (T25).
Tighten the screws until the insulation around the
screw holes deforms slightly.
3.3.4 Reversing the inner tank
For horizontal mounting, the inner tank can be
reversed if it is desirable to swap the CW and HW
connections for ease of fitting. Important: This
can only be done when the electricity is not con-
nected.
1.
Remove the insulation (see 3.3.2).
2.
Remove the electrical cover by loosening
the nut (E). Then unscrew the strain reliever
for the mains cable (F) and remove the elec-
trical cover.
3.
The electrical cover (I) may be modified by
opening the alternative fixing for the strain
reliever (K). Material in the recess should be
removed and the strain reliever with cable

fitted into the new channel.
4.
Remove the fastening band (V). Pull the tank
out so the connections clear the attachment
points (H). Turn the tank 180° and push it
back into the attachment points. Refit the
fastening band.
5.
Ensure that connections and the coloured
rings (red/blue) indicating HW and CW are
positioned correctly in the slots.
6.
Fit the electrical cover with the nut (E), then
fit the insulation cap. The end-parts of the
insulation must now swap places.
7.
The product has built-in channels in the
back (J) for simple and tidy routing of the
mains cable at the back of the product.
