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
• Small Footprint - Extremely lightweight with a compact foot-
print, it is a perfect fit for any application.
• Quality Condenser Coils - The coil is constructed of alumi-
num microchannel tubing and enhanced aluminum fins for
reduced size and increased efficiency.
• Coil Protection - Coils are protected from damage by
a sturdy polymer mesh and a coated steel wire coil guard.
• Optional Factory E-Coat - Available ElectroFin
on select models.
• Protected Compressor - Compressors are protected inter-
nally by a high pressure relief valve and a temperature sen-
sor, and externally by the system high pressure switch. A
factory installed liquid line filter-drier further protects the
compressor against moisture and debris.
• Environmentally Friendly Refrigerant - The next genera-
tion refrigerant R-410A delivers environmentally friendly per-
formance with zero ozone depletion.
• Durable Finish - The cabinet is made of G90-equivalent pre-
painted steel, with special primer formulas and matte cham-
pagne texture to insure less fading when exposed to sun-
light. The coated steel wire fan and coil guards and pre-
treated, galvanized steel chassis components resist corro-
sion and rust creep.
• Lower Installed Cost - Installation time and costs are
reduced by easy power and control wiring connections. The
unit is factory charged for a 15-foot lineset. The small base
dimension means less space is required on the ground or
roof.
• Top Discharge - Warm air from the top mounted fan is blown
up, away fro0m the structure and any landscaping. This
allows compact location on multi-unit applications.
• Competitive Sound Levels - 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 condenser coil muffle the nor-
mal 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 con-
nections for ease of evacuating and charging.
• Agency Listed - Safety certified by CSA to UL 1995 / CSA
22.2. Performance certified to ANSI/AHRI Standard 210/240
in accordance with the Unitary Small Equipment certification
program.
