DESCRIPTION
The HTS Stealth series condensing units use Twin Single compressor
technology to provide cooling efficiencies up to 16.7 SEER. They are to
be installed with the matching variable speed Enhancer air handler or Dia-
mond furnace, or with a two-stage or single-stage indoor unit, a corre-
sponding coil and sweat connect lines. A factory specified balanced port
hard shut-off TXV kit must be used for proper installation and optimum
performance. These units are backed by a 10 - year limited warranty on
the compressor and 1 - year on all other parts.
FEATURES
QUALITY CONDENSER COILS - The coil is constructed of copper tube
and hardened aluminum fins for durability and long lasting efficient opera-
tion. The fins on the unit are protected with a decorative grille.
DURABLE FINISH - Cabinet is made of powder painted steel over pre-
painted primer. The pre-treated flat galvanized steel provides a better
paint to steel bond, which resists corrosion and rust creep. Special primer
formulas and glossy earth tone finish insure less fading when exposed to
sunlight. This finish has been tested to provide 1/3 greater protection than
conventional units.
PROTECTED COMPRESSORS - The Twin Single compressor is pro-
tected 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 controlboard
optimizes the compressor staging based on load requirements, provides a
5-minute anti-short cycle timer for each compressor, and simplifies trou-
bleshooting 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 refrig-
erant 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 Single compressor provide
effective humidity control at the lowest 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 loca-
tion on multi-unit applications.
LOW OPERATING SOUND LEVEL - The upward air flow carries the nor-
mal operating noise up 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 com-
pressor operating sounds.
LOW MAINTENANCE - Long life permanently lubricated motor- bearings
need no annual servicing.
EASY SERVICE ACCESS - Fully exposed refrigerant connections and a
single panel covering the electrical controls make servicing easy. Easy
access for coil clearing is also provided.
RE-USABLE SERVICE VALVES - Provided on both the liquid and vapor
sweat connections for ease of evacuating and charging.
