DESCRIPTION
The 14.5 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 - The compact footprint is a perfect fit for
any application.
• Quality Condenser Coils - The coil is constructed of copper
tubing and enhanced aluminum fins for increased perfor-
mance.
• Coil Protection - Coils are protected from damage by a slot-
ted, stamped steel coil guard.
• Protected Compressor - Compressors are protected inter-
nally by a high pressure relief valve and a temperature sen-
sor, and externally by the system high and low pressure
switches. A factory installed liquid line filter-drier further pro-
tects the compressor against moisture and debris. The 5-ton
system utilizes a two-stage compressor.
• 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 guard and pre-treated,
galvanized steel chassis components resist corrosion 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 from the structure and any landscaping. This allows
compact location on multi-unit applications.
• Quiet Operation - The compressor sound blanket and the
swept wing fan blade keep sound to a minimum. The upward
air flow carries the normal operating noise away from the liv-
ing area. The rigid top panel effectively isolates any motor
sound. Isolator mounted compressor and 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 con-
nections for ease of evacuating and charging.
• Advanced System Control - These heat pumps feature a
demand-defrost control system to provide optimal comfort
and reliable operation over a wide range of conditions.
• 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.
