• Ensure a minimum clearance of three (3) inches around
the unit for adequate airflow.
• Ensure the condensate drain is unobstructed and leak-
free.
NOTE: The wall sleeve has a 3/4 NPT nipple located in the
bottom for connection to the drain. A trap may be required
in the condensate drain line to prevent sewer gas from
escaping into the room.
SLEEVE INSTALLATION
Refer to installation instructions packed with wall sleeve to
assemble and mount it in the wall. Ensure that the construc-
tion debris guard is removed and that the bottom of the wall
sleeve is pitched 1/2 bubble toward the outside of the
building. This angle forces any rain water that might enter
to drain to the outside. Also inspect the bottom of the wall
sleeve pan and drain. They should be clear of obstruction
and operational.
