DESCRIPTION
The 13 SEER Series unit is the outdoor part of a versatile cli-
mate system. It is designed with a matching indoor coil compo-
nent from Johnson Controls Unitary Products. Available for
typical applications this climate system is supported with acces-
sories and documents to serve specific functions.
FEATURES
• Quality Condenser Coils - The coil is constructed of copper
tubing and enhanced aluminum fins for increased efficiency
and corrosion protection.
• Protected Compressor - The compressor is internally pro-
tected against high pressure, temperature, and externally by
a factory installed high pressure switch. This is accomplished
by the simultaneous operation of high pressure relief valve
and a temperature sensor which protects the compressor if
undesirable operating conditions occur. A liquid line filter-
drier further protects the compressor.
• Durable Finish - The cabinet is made of pre-painted steel.
The pre-treated galvanized steel provides a better paint to
steel bond, which resists corrosion and rust creep. Special
primer formulas and matted-textured finish insure less fading
when exposed to sunlight.
• Lower Installed Cost - Installation time and costs are
reduced by easy power and control wiring connections.
Available in sweat connect models only. The unit contains
enough refrigerant for matching indoor coils and 15 feet of
interconnecting piping. The small base dimension means
less space is required on the ground or roof.
• Top Discharge - The warm air from the top mounted fan is
blown up away from the structure and any landscaping. This
allows compact location on multi-unit applications.
• Low Operating Sound Level - The upward air flow carries
the normal operating noise away from the living area. The
rigid top panel effectively isolates any motor sound. Isolator
mounted compressor and the rippled fins of the condenser
coil muffle the normal fan motor and compressor operating
sounds.
• Low Maintenance - Long life permanently lubricated motor-
bearings need no annual servicing.
• Easy Service Access - Fully exposed refrigerant connec-
tions, and a single panel covering the electrical controls
make for easy servicing of the unit.
• Secured Service Valves - Secured re-usable service valves
are provided on both the liquid and vapor sweat connections
for ease of evacuating and charging.
• U.L. and C.U.L. listed - approved for outdoor application.
• Agency Listed - U.L. and C.U.L. listed - approved for out-
door application. The unit is certified in accordance with the
Unitary Small Equipment certification program, which is
based on ARI Standard 210/240.
