DESCRIPTION
The ETS Stealth series heat pump units use Twin Single
™
compressor technology to provide cooling efficiencies up to
15.7 SEER and heating efficiencies up to 9.3 HSPF. They are
to be installed with the matching variable speed Enhancer air
handler or Diamond furnace, 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 per-
formance.
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 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 conven-
tional units.
PROTECTED COMPRESSORS - The Twin Single
™ compres-
sor is protected against high 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, 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 connec-
tions 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.
