l
The WHISPA III
®
wall units are designed so that the piping
and wiring connections are made within the cabinet of the
unit itself. The installer should inspect the unit and note that
the 1
/
2" piping should enter on the lower right hand corner of
the unit and the 110V AC wiring for the unit enters on the
lower left hand corner of the unit, see Fig 2.
l
Prepare the opening in the wall to accept the unit as shown
in Fig 1. Depending on the wall framing layout, the 9000
model may require re-framing of the opening to ensure
proper support.
l
Do not fit the unit at this stage. Consideration should be
given to making the electrical connection (section 6) and
making the connection to the hot water circuit (section 7)
prior to fitting the unit into the wall cavity.

corner of the unit for BX or Romex convector.

l
Use suitable sized wire connectors and replace the electrical
panel cover.
l
Depending on the wall construction, the installer will need to
decide whether it would be best to fit the unit first and then
bring in the piping, or to bring the piping in first. Once this
decision has been made, place the unit in position (fan at
bottom) and secure to the framing with suitable screws. Use
all the fixing holes, see Fig 2.
l
Bring
1
/
2
" copper tubing from the heating loop to the unit
and make sweat connections.
l
Many installers are now beginning to use flexible heat tubing
to make these connections. Ensure prior to use that the
tubing selected is appropriate for the water temperature to
be supplied.
WARNING: This appliance must be grounded.
Do not energize the electrical supply until the remaining stages of the installation have been completed.
