INSTALLING TWO EXTERIOR HOODS
Choose an appropriate location to install the exterior hoods:
¢ There must be a minimum distance of 6-{ft (1.8 m) between the
hoods to avoid cross-contamination
¢ There must be a minimum distance of 18-in (457 mm) from the
ground
Make sure the intake hood is at least 6 feet (1.8 m) away from the
following:
¢ Dryer exhaust, high efficiency furnace vent, central vacuum vent
* Gas meter exhaust, gas barbecue grill
¢ Any exhaust from a combustion source
* Garbage bin and any other sources of contamination
Refer to figure beside for connecting insulated ducts to the exterior
hoods. An "Anti-gust intake hood" should be installed in regions
where a lot of snow is expected to fall.

Connecting the drain
Cut 2 sections of the plastic tube, at least 16-in (406 mm) long,
and attach them to each inner drain fitting, located under the unit.
Join both short sections to the "T" junction
and main
tube as
shown in Fig. 18.

Make a water trap loop in the tube to prevent the unit from drawing
unpleasant odors from the drain source. Make
sure this loop is
located OVER the "T" as shown. Run the tube to the floor drain or
to an alternative drain pipe or pail.
IMPORTANT:
If using a pail to collect water, locate the tube end
approximately 1-in (25 mm) from the top of the pail in order to
prevent water from being drawn back up into the unit.

CONTROLS
This unit is equipped with an integrated control located under the
unit, on the recessed side of electrical compartment. Plug the unit.
Unit booting sequence
The unit booting sequence is similar to a personal computer boot
sequence. Each time the unit is plugged in after being unplugged,
or after a power failure, the unit will perform a 30-second booting
sequence before starting to operate.
During the booting sequence, the integrated control LED will light
GREEN
(unit set in normal
defrost)
or AMBER
(unit
set in
extended
defrost)
for
5
seconds,
and
then
will
shut
off
for
2
seconds. After that, the LED
will light RED
for the rest of the
booting
sequence.
During
this
RED
light
phase,
the
unit
is
checking and resetting the motorized damper position. Once the
motorized damper position completely set, the RED light turns off
and the booting sequence is done.
NOTE:
No command will be taken until the unit is fully booted.
Integrated control
Use the push button (1) to control the unit. The LED (2) will then
show on which mode the unit is in. See Fig. 20.
