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.

SYSTEM OPERATION
This heat pump model is equipped with both YorkGuard V
heat pump control and TS compressor control. The interface
control 6CF board is used to bypass the first stage of heat
when the outdoor temperature falls below certain tempera-
tures. The TS control board is used only to switch between 1
and 2 cylinder operation. The fault codes and pressure switch
on the TS control board are bypassed using the jumpers
between the test and "PS" pins.
1. Anti-short Cycle Timer
The five-minute time delay on YorkGuard V will be used
to prevent the system from short cycling after the ther-
mostat off or power interrupt. This time delay can be
bypassed by temporarily shorting the test terminals on
YorkGuard V for 3 seconds. Since a jumper was factory
installed across the test pins on the TS control board, the
anti-short cycle timer on the TS control board is
bypassed.
2. First Stage Cooling
This heat pump model is equipped with a Twin-Single
compressor. With a call for first stage cooling, the com-
pressor operates one cylinder. The run winding (R) is
connected through the upper left contactor (A) and to the
capacitor and the start winding (S) is connected to line
voltage. The system operates at low discharge pressure
and high suction pressure.
3. Second Stage of Cooling
With a call for second stage cooling, the TS control will
shut the compressor off for two seconds then energize
relays R1 and R2 on the TS control board. This will de-
energize (open) the upper left contactor (A) and energize
(close) the lower right contactor (B), connecting the com-
pressor run winding (R) to the line voltage and start
winding (S) to the capacitor. The compressor runs in the
reverse direction with two cylinders compared to the first
stage. The system will operate with two cylinders until
both first and second stage are satisfied. The Y2OUT
signal from the relay board causes the indoor blower to
function at high speed.
If the room thermostat calls for second stage cooling
(Y2) on two consecutive cooling cycles, the next call for
cooling for either first or second stage will energize the
unit in second stage mode. The above mode will be reset
to permit start up on the first stage with only a Y1 call
when the second stage operation cycle runs less than 15
minutes or when 24V to the TS control board is discon-
nected.
4. 6K Relay on the 6CF Control Board
The 6K relay on the 6CF interface board operates as fol-
lows. See Figure 1:
a. If the YorkGuard V defrost control balance point set-
ting is 45°F, the 6K relay will be:
• Energized if liquid temperature goes below 35°F.
• De-energized if the liquid temperature goes above
35°F AND the ambient is greater than 42°F for five
minutes AND the unit is not in defrost.
b. If the YorkGuard V defrost control balance point set-
ting is at anything but 45°F, the 6K relay will be:
• Energized if liquid temperature goes below 45°F.
• De-energized if the liquid temperature goes above
45°F AND the ambient is greater than 55°F AND
the unit is not in defrost.
5. Heating mode with the de-energized 6K relay
The TS compressor operates similar to the first and sec-
ond stage of cooling modes except there is no O input
from the thermostat, the reversing valve is not energized,
and the system operates in heating heat pump mode.
The YorkGuard V control and the liquid temperature will
not allow the system to go into the defrost mode.
6. Heating mode with the energized 6K Relay
The energized 6K relay on the interface board (6CF) will
connect Y1 and Y2 and disconnect Y2OUT from the TS
control to the indoor blower if the J1 pin is not in the ON
position. The compressor will operate only in second
stage regardless of the first or second stage call from the
thermostat. The indoor blower will operate in low air
mode. The indoor discharge air temperature should be
about 10°F hotter than a normal heat pump. If high-
speed air is preferred, move J1 pin to the ON position at
the interface board (6CF). This will send the Y2OUT sig-
nal back to the indoor blower for the high speed air.

1. Cooling MBH based on 80° F entering air temperature, 50% RH and rated airflow.
2. SEER (Seasonal Energy Efficiency Ratio) equals the total cooling output in BTU’s during a normal annual usage period for cool-
ing divided by the total electric power input in watt-hours during the same period. Normal annual usage is a combination of both
one and two cylinder operating periods.
3. EER (Energy Efficiency Ratio) equals the total cooling output in BTU’s at 95° F outdoor ambient divided by the total electric power
in watt-hours at those conditions.

1. Heating MBH based on ARI standards of 70° DB entering indoor air, 72% RH outdoor air with 25 feet of interconnecting piping and
no supplemental electric heat operation.
2. Integrated heating capacities include the effect of defrost cycles in the temperature range where they occur.
3. HSPF (Heating Seasonal Performance Factor) is the total heating output during a normal annual usage period for heating divided
by the total electric power input during the same period.
4. COP equals MBH output divided by (total KW input x 3.412).
