No-Rust Weather Last™ Wall Sleeve And Front Panel; Removable Front Panel; Anti-Theft Knobs - Carrier PREMIER 52P SERIES Architects And Engineers' Manual

NO-RUST WEATHER LAST™
WALL SLEEVE AND FRONT
PANEL
The indoor front panel and polymer wall sleeve use
nonmetallic compounds that never rust or corrode, do
not support combustion, and do not give off toxic
fumes. The weather-resistant feature exceeds require-
ments of Underwriters' Laboratories and resists dam-
age caused by impact and scratching. The Weather
Last feature also insulates and has up to 10 times the
acoustic absorption of metal cabinets.
Insulated polymer wall sleeves combine all of the
above features with factory-installed insulation. The
insulation helps to reduce heat loss, save energy, pro-
vide better sound absorption, and reduce the risk of
sleeve sweating.
Carrier's metal wall sleeves are available in a variety
of sizes for most standard and deep wall applications.
All metal wall sleeves come with factory-installed
insulation, designed to minimize heat loss and reduce
outdoor noise transmissions into the room.

REMOVABLE FRONT PANEL

The louvered front panel fits firmly onto the chassis
and features easy removal for service. It provides front
air intake to enhance performance and quiet operation.
It also allows the option of flush mounting PTAC unit
to the floor. If desired, the front panel can be
secured to the unit with field-supplied screws.
2 locking screws (if installed) are located behind the
removable filter handles.

ANTI-THEFT KNOBS

The anti-theft knobs are captured underneath the front
panel of the unit to prevent the knobs from being
removed or stolen.
