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 lb 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 1
1
/
2
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 valve opens when the
outdoor temperature drops below 45 F to prevent
water from freezing in the basepan.
CONDENSATE REMOVAL
SYSTEM
Carrier’s 52P and 52C Series units have an improved
condensate (water) disposal system. In addition to
slinger ring technology, Carrier has developed and pat-
ented a Condensate Suction Port. The suction port,
alongwiththeslingerring,drawsinwaterwhichis
sprayed up onto the outdoor coil. The water then evap-
orates, thus providing better disposal of excess con-
densate, improving unit efficiency.
NOTE: If it is necessary to remove 100% of the con-
densate, the Carrier Drain Kit (Part No.: DRAIN-KIT-
4PK) is recommended.
