The WHISPA III
®
RCU fan convector is 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 ½" piping should enter on the lower right corner of
the unit and the 120V 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 9,000 and
12,000 models 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 the
connection to the hot water circuit (section 7) prior to fitting
the unit in the wall cavity.
