PRODUCT FEATURES AND BENEFITS (cont)

ENHANCED COPPER TUBING

Enhanced copper tubing is more efficient and durable
and can be repaired in the field, if required.
Because copper is a very stable metal, it is durable and
resists corrosion. Enhanced copper tubing increases:
• heat transfer capability
• the efficiency of the cooling and heating processes
• thermal conductivity (by creating additional tube
surface and turbulent refrigerant gas flow)
Every Carrier PTAC coil undergoes thorough leak test-
ing and pressure testing up to 350 lbs per square inch.

SEAMLESS BASEPAN

Seamless drawn basepan walls add protection against
water accumulation resulting from storm-driven rain
with heavy wind.
Carrier's deep basepan holds up to two gallons of
water without spilling. Closed cell foam insulators are
located between the basepan and coils, keeping coils
from direct contact with the basepan and providing
additional protection against corrosion.

CONDENSATE DRAIN VALVE

The temperature-activated drain opens when the out-
door temperature drops below 45 F to prevent water
from freezing in the basepan.
CONDENSATE REMOVAL
SYSTEM
Carrier's 52S Series units have a slinger ring around
the outside of the outdoor fan propeller. Condensate
(water) in the unit basepan is picked up by the slinger
ring and dispersed onto the hot outdoor condenser
coil. The heat from the coil evaporates the con-
densate and cools the coil at the same time, thereby
removing condensate and increasing the unit's
efficiency.
NOTE: If it is necessary to remove 100% of the con-
densate, we recommend using the Carrier Drain Kit
(Part No.: DRAIN-KIT-4PK).

CARRIER WARRANTY

Carrier's full one-year warranty is the most compre-
hensive in the industry. In addition, Carrier provides:
• Full coverage for parts and labor.
• Four additional years of coverage on sealed refrig-
eration systems.
• Limited second through fifth year coverage on non-
refrigeration system parts.
