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:
S
heat transfer capability
S
the efficiency of the cooling and heating
processes
S
thermal conductivity (by creating additional
tube surface and turbulent refrigerant gas
flow)
Every Carrier PTAC coil undergoes thorough leak
testing and pressure testing.
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--3/4 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 55
_
F to prevent
water from freezing in the basepan.

CONDENSATE REMOVAL
Carrier’s 52M Series unit has a new condensate
(water) disposal system. In addition to slinger ring
technology, Carrier has developed and patented a
Condensate Suction Port. The suction port, along
with the slinger ring, draws in water which is sprayed
up onto the outdoor coil. The water then evaporates,
thus providing better disposal of excess condensate
and improving unit efficiency.
NOTE
: If it is necessary to control 100% of the
condensate, the Carrier Drain Kit (Part No.:
DRAIN--KIT--4PK) is recommended.
