Before attaching the heater to the wall, consider the wiring route to the heater.
The electrical cable can enter the heater through the opening in the back for concealed
cabling. Knock out panels in the top right corner of the back plate and front cover are
available for side entry.
Remove the front cover from the heater by means of the single screw located between
the inlet and outlet fittings.The cover will lift first from the bottom and then unhook
from the top. Carefully release the PCB lead from the main unit to completely uncouple
the cover.
It is advised that the heater be located as close as practical to the hot water outlet in
order to avoid unnecessary heat losses through the pipework.
Once the preferred location has been decided, offer the heater to the wall. Ensure the
unit is level and mark the hole locations onto the final mounting surface (see diagram
on previous page).
Ensure there are no hidden cables or pipes before commencement of drilling.
Take the heater away from the mounting surface and drill the holes marked from the
previous step.
Insert wall plugs and offer the heater back up to the mounting surface. Locate the
screws through the unit and into the wall plugs and screw down securely.
Plumbing
Ensure the following criteria are met for the water supply:
•
Minimum flow = 2.5L/min
•
Pressure Min/Max = 0.1Mpa/0.75Mpa
•
Water resistivity = ≥1300 Ωcm
Suitable for use with pre-heated water e.g. solar heating systems to a maximum
of 60
0
C.
Flush supply pipes to remove any debris before connecting the heater to the
water supply.
