Enhanced Copper Tubing; Seamless Basepan; Condensate Drain Valve; Condensate Removal System - Carrier 52P User Manual

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 1
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 Orifice. The orifice, along with the
slinger ring, draws in water which is sprayed up onto
the outdoor coil. The water then evaporates, thus pro-
viding better disposal of excess condensate, improving
unit 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).
