DESCRIPTION

The HTS Stealth series condensing units use Twin Single
compressor technology to provide cooling efficiencies up to
15.5 SEER. They are to be installed with the matching vari-
able speed enhanced Air Handler or Diamond Furnace, or
with a two-stage or single-stage indoor unit, a corresponding
coil and sweat connect lines. A factory specified balanced
port hard shut-off TXV kit must be used for proper installation
and optimum performance.
WARRANTY
5-year limited parts warranty.
10-year limited compressor warranty.

FEATURES

• QUALITY CONDENSER COILS - The coil is constructed of
copper tube and hardened aluminum fins for durability and
long lasting efficient operation. The fins on the unit are pro-
tected with a decorative grille.
• DURABLE FINISH - Cabinet is made of powder painted steel
over pre-primered steel. The pre-treated galvanized steel pro-
vides a better paint to steel bond, which resists corrosion and
rust creep. Special primer formulas and automotive quality fin-
ish insure less fading when exposed to sunlight.
• PROTECTED COMPRESSORS - The Twin Single com-
pressor is protected against high and low pressure. Hard start
components are included to ensure start-up under adverse
conditions. All models have standard crankcase heat for
added protection.
• OPTIMUM PERFORMANCE - The solid-state electronic con-
trolboard optimizes the compressor staging based on load
requirements, provides a 5-minute anti-short cycle timer for
the compressor, and simplifies troubleshooting with built in
self diagnostics.
• LOWER INSTALLED COST - Installation time and costs are
reduced by easy power and control wiring connections. All
units contain enough refrigerant for the smallest matching
indoor coil and 15 feet of interconnecting piping. The small
base dimension means less space is required on the ground
or roof.
• EFFECTIVE HUMIDITY CONTROL - The inherent design of
the Stealth system and the staging operation of the Twin Sin-
gle compressor provide effective humidity control at the low-
est possible operating cost. An optional dehumidification
control accessory is available to maintain the humidity at a set
desired level.
• 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 car-
ries the normal operating noise up away from the living area.
The rigid top panel effectively isolates any motor sound. Isola-
tor 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 con-
nections and a single panel covering the electrical controls
make servicing easy. Easy access for coil cleaning is also pro-
vided.
• RE-USABLE SERVICE VALVES - Provided on both the liquid
and vapor sweat connections for ease of evacuating and
charging.
Certified in accordance with the Unitary Small Equipment cer-
tification program, which is based on ARI Standard 210/240.
