to route return ductwork to the unit or allow for unrestricted
airflow in an open return configuration. To reduce the possible
transmission of sound and vibration, a resilient material such as
rubber or cork should be installed between the support and the
base of the unit. All spaces around the top, sides, and bottom of
the exterior grille area should be caulked and sealed to the wall,
making sure that the openings for drainage in the bottom edge
are not blocked.
If the optional wall sleeve is used, caulk the spaces between the
sleeve and the wall. Completely fill the clearance on all sides
between the unit and the wall sleeve with a polyurethane foam
sealant (follow manufacturer’s suggested application manual).
NOTE: FOR EASE OF INSTALLATION, INSTALL
THE CABINET INTO THE WALL SLEEVE FIRST
WITHOUT THE COOLING CHASSIS. THEN SLIDE
COOLING CHASSIS IN AFTER CABINET IS IN
PLACE.
Drainage
The 3/4" I.D. flexible tubing included should be connected to the
Comfort Pack primary drain connection so that it can easily be
disconnected if the cooling chassis must be removed. A trap
at least 2" deep should be provided close to the drain pan. The
tubing should not be higher than the bottom of the unit drain
pan at any point to assure proper drainage and allow chassis
removal. The drain line should pitch downward at least 1" per
10 ft. to an open building drain trap.
