Figure 3: Drilling the hole for the vent sensor in a GEN II Compac unit. Note
the hose on the drill bit to prevent drilling too deep.
STEP 1
VENT SENSOR INSTALLATION:
Using a 3/8" drill bit, with a hose
installed (see important note above),
drill a hole in the case in the side
containing the vent and floor outlets
(see figure 3) at location A (figures
5,6). This hole should be placed at
about the center of the module, about
¾" above the seam of the case (with
vent openings as top). Push one of
the temp sensors into this hole,
leaving the wires to the outside. This
sensor will be wired to the VENT+ and
VENT- terminals on the control box as
shown in the wiring diagram on the
first page (figure 1).
STEP 2
FLOOR SENSOR INSTALLATION:
Using a 3/8" drill bit, with hose
installed (see important note), drill a
hole in the GEN II case in the floor
outlet ducting at point B (figures 5,6).
Insert the second temperature sensor
into the hole so that the wires are to
the outside of the duct. This sensor
will be wired to the FLOOR+ and
FLOOR- terminals on the control box
as shown in wiring diagram.
STEP 3
CABIN SENSOR INSTALLATION:
Using a 3/8" drill bit, with hose
installed (see important note) drill a
hole in the fan shroud at point C
(figures 5,7). Insert the last sensor into
the hole with the wires to the outside.
This sensor will be wired to the
CABIN- and CABIN+ terminal on the
control box as shown in the wiring
diagram.
STEP 4
EVAPORATOR PROBE INSTALL:
Push the evaporator probe into the
hole in the GEN II module marked
with the sticker for the capillary tube.
The metal portion of the probe should
go almost completely into the GEN II
unit.
