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.
