The 51 CV/GY is normally installed through a wall.
During installation, you will remove the unit’s chassis
from the casing, install the casing first and then re-insert
the chassis. To slide out chassis, you must first loosen
the chassis security screw.
CAUTION: COIL FINS ON CHASSIS ARE SHARP AND
CHASSIS IS HEAVY.
NOTE: This unit may also be installed in a window. An
additional accessory kit must be ordered separately for
window mounting. Contact your independent Carrier
Dealer, or call 1-800-CARRIER for information, and
refer to page 9 for Window Installation Steps.
Two people recommended for installation.

Note: If wall thickness obstructs unit’s side vents, make wall
opening wider as shown in Figure A. Allow for condensate
drainage from thermostatic drain valve located in basepan. If

wall and mounting angles if desired. If mounting
angles are used, you may choose to use a plaster
NOTES
Through-the- Wail Installation of the air conditioner unit is
possible in wood framing or masonry weJI, using units casing
as a sleeve. Installation should be level as unit has a built-in
pitch for draining condensation.
Good framing construction practices must be used to ensure
a properly installed unit.
