WARNING
WARNING
YSTEM CONTAMINANT S, IMPROPER SERVICE PROCEDU RE AND/OR PHYSICAL
S
ABUSE AFFECTING HE RMETIC COMPRESSOR ELECTRICAL TERMINALS MAY
CAUSE DANGEROUS SYSTEM VENTING.
The successful development of hermetically sealed refrigeration compressors has completely sealed the compressor's
moving parts and electric motor inside a common housing,
minimizing refrigerant leaks and the hazards sometimes
associated with moving belts, pulleys or couplings.
Fundamental to the design of hermetic compressors is a
method whereby electrical current is transmitted to the
compressor motor through terminal conductors which pass
through the compressor housing wall. These terminals are
sealed in a dielectric material which insulates them from the
housing and maintains the pressure tight integrity of the
hermetic compressor. The terminals and their dielectric
embedment are strongly constructed, but are vulnerable to
careless compressor installation or maintenance procedures and equally vulnerable to internal electrical short
circuits caused by excessive system contaminants.
T
O AVOID POSSIBLE INJURY, EXPLOSION OR DEATH, PRACTICE SAFE
HANDLING OF REFRIGERAN TS.
In either of these instances, an electrical short between the
terminal and the compressor housing may result in the loss
of integrity between the terminal and its dielectric embedment. This loss may cause the terminals to be expelled,
thereby venting the vaporous and liquid contents of the
compressor housing and system.
A venting compressor terminal normally presents no danger
to anyone, providing the terminal protective cover is properly
in place.
If, however, the terminal protective cover is not properly in
place, a venting terminal may discharge a combination of
(a ) hot lubricating oil and refrigerant
(b ) flammable mixture (if system is contaminated
with air)
in a stream of spray which may be dangerous to anyone in the
vicinity. Death or serious bodily injury could occur.
Under no circumstances is a hermetic compressor to be
electrically energized and/or operated without having the
terminal protective cover properly in place.
See Service Section S-17 for proper servicing.

PRODUCT DESIGN
This section gives a basic description of cooling unit operation, its various components and their basic operation.
Ensure your system is properly sized for heat gain and loss
according to methods of the Air Conditioning Contractors
Association (ACCA) or equivalent.
CONDENSING UNIT
The condenser air is pulled through the condenser coil by a
direct drive propeller fan. This condenser air is then discharged out of the top of the cabinet. These units are
designed for free air discharge, so no additional resistance,
like duct work, shall be attached.
The suction and liquid line connections on present models
are of the sweat type for field piping with refrigerant type
copper. Front seating valves are factory installed to accept
the field run copper. The total refrigerant charge for a normal
installation is factory installed in the condensing unit.
GSX, GSZ, ASX, ASZ, SSX, SSZ, DSX, DSZ, VSX, and VSZ
models are available in 1 1/2 through 5 ton sizes and use R410A refrigerant. They are designed for 208/230 volt single
phase applications.
GSX/GSZ *****2 models are available in 2 and 3 ton sizes and
use R-410A refrigerant. They are designed for 220/240 volt
single phase applications.
GSX/GSZ *****3 models are available in 3, 4, and 5 ton sizes
and use R-410A refrigerant. They are designed for 208/230
volt 3-phase applications.
GSX/GSZ *****4 models are available in 3, 4, and 5 ton sizes
and use R-410A refrigerant. They are designed for 380/420
volt 3-phase applications.
GSX/GSZ *****5 models are available in 3, 4, and 5 ton sizes
and use R-410A refrigerant. They are designed for 380/420
volt 3-phase applications.
ASX, ASZ, DSX and DSZ R-410A model units use the
Copeland Scroll "Ultratech" Series compressors which are
specifically designed for R-410A refrigerant. These units also
have Copeland
GSX, GSZ, SSX, SSZ, VSX, and VSZ R-410A model units,
except for GSX130181C*, VSX130181B*, VSX130241E*,
VSX130421B*, and VSX130481B*, use the Copeland Scroll
"Ultratech" Series compressors which are specifically designed for R-410A refrigerant.
ASXC, ASZC, DSXC, DSZC models are available in 2
through 5 ton sizes and use R-410A refrigerant. They are
designed for 208/230 volt single phase applications.
ASXC, ASZC, DSXC, DSZC R-410A model units use the
Copeland Scroll "Ultratech" Series compressors which are
specifically designed for R-410A refrigerant. These units also
have Copeland® ComfortAlert diagnostics. The Copeland
ComfortAlert diagnostics are integrated into the unitary (UC)
control. These models are ComfortNetTM ready.
There are a number of design characteristics which are
different from the traditional reciprocating and/or scroll compressors.
®
ComfortAlert diagnostics.
"Ultractech" Series scroll compressors will not have a discharge thermostat. Some of the early model scroll compressors required discharge thermostat.
"Ultratech" Series scroll compressors use "POE" or
polyolester oil which is NOT compatible with mineral oil
based lubricants like 3GS. "POE" oil must be used if
additional oil is required.
COILS AND BLOWER COILS - LEGACY
MODELS
MBR/MBE/MBVC blower cabinets are designed to be used
as a two-piece blower and coil combination. MBR/MBE/
MBVC blower sections can be attached to cased evaporator
coil. This two-piece arrangement allows for a variety of mixmatching possibilities providing greater flexibility. The MBE/
MBVC blower cabinets use a variable speed motor that
maintains a constant airflow with a higher duct static.
MBE/MBVC blower cabinests are approved for applications
with cooling coils of up to 0.8 inches W.C. external static
pressure. The MBE models includes a feature that allows
airflow to be changed by +10% or -15%. The MBVC models
allow airflow trimming of +/-10%.
The MBR blower cabinet uses a PSC motor. It is approved for
applications with cooling coils of up to 0.5 inches W.C.
external static pressure.
The MBR/MBE/MBVC blower cabinets with proper coil
matches can be positioned for upflow, counterflow, horizontal
right or horizontal left operation. All units are constructed with
R-4.2 insulation. In areas of extreme humidity (greater than
80% consistently), insulate the exterior of the blower with
insulation having a vapor barrier equivalent to ductwork
insulation, providing local codes permit.
The CAUF, CAPF and CAPT coils are designed for upflow and
counterflow applications. The CACF and CHPF coils are
designed for horizontal applications.
Communicating Unitary Control (UC) PCB
The Communicating System Unitary Control PCB is a microprocessor-based control for heat pump and air conditioning
condensing units with single-phase compressors up to 5 ton
capacity operating on standard residential or Delta and Wye
commercial power. The control incorporates the basic functionality of existing defrost controls, outdoor thermostats,
contactors, compressor staging controls, short cycle controls, line voltage monitors, Comfort Alert™ or CoreSense
Module (dependent upon which module you are using), two
speed condenser fan relays and the Active Protection component of enabled thermostats. The control is designed to
work as part of a fully communicating HVAC system with 4
®
wires. The control also supports legacy 24VAC thermostat
inputs for Y1, Y2, O and 24VAC outputs for RVS, W1, and L
for non-communicating systems. Outputs include compressor power, compressor stage select, and outdoor fan high
and outdoor fan low speed. System inputs include high/low
pressure switches, as well as thermistor inputs for outdoor
coil temperature and outdoor air temperature.

PRODUCT DESIGN
The ASX & ASXC [16 & 18], ASZ & ASZC [16 & 18], DSX &
DSXC [16 & 18] and DSZ & DSZC [16 & 18] series split
system units use a two-stage scroll compressor. The twostep modulator has an internal unloading mechanism that
opens a bypass port in the first compression pocket, effectively reducing the displacement of the scroll. The opening
and closing of the bypass port is controlled by an internal
electrically operated solenoid.
The ZPS/ZRS two-step modulated scroll uses a single step
of unloading to go from full capacity to approximately 67%
capacity. A single speed, high efficiency motor continues to
run while the scroll modulates between the two capacity
steps.
FIGURE A
A scroll is an involute spiral which, when matched with a
mating scroll form as shown, generates a series of crescent
shaped gas pockets between the two members.
During compression, one scroll remains stationary (fixed
scroll) while the other form (orbiting scroll) is allowed to orbit
(but not rotate) around the first form.
As this motion occurs, the pockets between the two forms
are slowly pushed to the center of the two scrolls while
simultaneously being reduced in volume. When the pocket
reaches the center of the scroll form, the gas, which is now
at a high pressure, is discharged out of a port located at the
center.
During compression, several pockets are being compressed
simultaneously, resulting in a very smooth process. Both the
suction process (outer portion of the scroll members) and the
discharge process (inner portion) are continuous.
Some design characteristics of the Compliant Scroll compressor are:
• Compliant Scroll compressors are more tolerant of liquid
refrigerant.
NOTE: Even though the compressor section of a Scroll
compressor is more tolerant of liquid refrigerant, continued floodback or flooded start conditions may wash oil
from the bearing surfaces causing premature bearing
failure.
• "Ultratech" Series scroll compressors use "POE" or
polyolester oil which is NOT compatible with mineral oil
based lubricants like 3GS. "POE" oil must be used if
additional oil is required.
• Compliant scroll compressors perform "quiet" shutdowns
that allow the compressor to restart immediately without
the need for a time delay. This compressor will restart
even if the system has not equalized.
NOTE: Operating pressures and amp draws may differ
from standard reciprocating compressors. This information can be found in the unit's Technical Information
Manual.

PRODUCT DESIGN
CAPACITY CONTROL - LEGACY MODELS
During the compression process, there are several pockets
within the scroll that are compressing gas. Modulation is
achieved by venting a portion of the gas in the first suction
pocket back to the low side of the compressor thereby
reducing the effective displacement of the compressor. See
Figure A. Full capacity is achieved by blocking these vents,
increasing the displacement to 100%. A solenoid in the
compressor, controlled by an external 24-volt ac signal,
moves the slider ring that covers and uncovers these vents.
The vent covers are arranged in such a manner that the
compressor operates somewhere around 67% capacity when
the solenoid is not energized and 100% capacity when the
solenoid is energized. The loading and unloading of the two
step scroll is done “on the fly” without shutting off the motor
between steps. See Figure B below. The unloaded mode
default was chosen for two reasons:

SYSTEM OPERA TION
COOLING
The refrigerant used in the system is R-410A. It is a clear,
colorless, non-toxic and non-irritating liquid. R-410A is a
50:50 blend of R-32 and R-125. The boiling point at atmospheric pressure is -62.9°F.
A few of the important principles that make the refrigeration
cycle possible are: heat always flows from a warmer to a
cooler body. Under lower pressure, a refrigerant will absorb
heat and vaporize at a low temperature. The vapors may be
drawn off and condensed at a higher pressure and temperature to be used again.
The indoor evaporator coil functions to cool and dehumidify
the air conditioned spaces through the evaporative process
taking place within the coil tubes.
NOTE: The pressures and temperatures shown in the
refrigerant cycle illustrations on the following pages are for
demonstration purposes only. Actual temperatures and pressures are to be obtained from the "Expanded Performance
Chart".
Liquid refrigerant at condensing pressure and temperatures,
(270 psig and 122°F), leaves the outdoor condensing coil
through the drier and is metered into the indoor coil through
the metering device. As the cool, low pressure, saturated
refrigerant enters the tubes of the indoor coil, a portion of the
liquid immediately vaporizes. It continues to soak up heat and
vaporizes as it proceeds through the coil, cooling the indoor
coil down to about 48°F.
Heat is continually being transferred to the cool fins and tubes
of the indoor evaporator coil by the warm system air. This
warming process causes the refrigerant to boil. The heat
removed from the air is carried off by the vapor.
As the vapor passes through the last tubes of the coil, it
becomes superheated. That is, it absorbs more heat than is
necessary to vaporize it. This is assurance that only dry gas
will reach the compressor. Liquid reaching the compressor
can weaken or break compressor valves.
The compressor increases the pressure of the gas, thus
adding more heat, and discharges hot, high pressure superheated gas into the outdoor condenser coil.
In the condenser coil, the hot refrigerant gas, being warmer
than the outdoor air, first loses its superheat by heat transferred from the gas through the tubes and fins of the coil. The
refrigerant now becomes saturated, part liquid, part vapor and
then continues to give up heat until it condenses to a liquid
alone. Once the vapor is fully liquefied, it continues to give up
heat which subcools the liquid, and it is ready to repeat the
cycle.
HEATING
The heating portion of the refrigeration cycle is similar to the
cooling cycle. By energizing the reversing valve solenoid coil,
the flow of the refrigerant is reversed. The indoor coil now
becomes the condenser coil, and the outdoor coil becomes
the evaporator coil.
The check valve at the indoor coil will open by the flow of
refrigerant letting the now condensed liquid refrigerant bypass the indoor expansion device. The check valve at the
outdoor coil will be forced closed by the refrigerant flow,
thereby utilizing the outdoor expansion device.
The restrictor orifice used with the CA*F, CHPF and CH**FCB
coils will be forced onto a seat when running in the cooling
cycle, only allowing liquid refrigerant to pass through the
orifice opening. In the heating cycle, it will be forced off the
seat allowing liquid to flow around the restrictor. A check valve
is not required in this circuit.
COOLING CYCLE
For legacy room thermostat: When the room thermostat calls
for cool, the contacts of the room thermostat close making
terminals R to Y1 & G (if thermostat calls for low stage cool),
or R to Y1, Y2 & G (if thermostat calls for high stage cool),
the low voltage circuit of the transformer is completed.
Current now flows through the magnetic holding coils of the
compressor contactor (CC) and fan relay (RFC). If thermostat
calls for high stage cool, the microprocessor on the UC board
will also energize the compressor high stage solenoid to run
the compressor at full capacity.
This draws in the normally open contact CC, starting the
compressor and condenser fan motors in either low or high
stage depending on the thermostat’s demand. At the same
time, contacts RFC close, starting the indoor fan motor.
When the thermostat is satisfied, it opens its contacts,
breaking the low voltage circuit, causing the compressor
contactor and indoor fan relay to open, shutting down the
system.
If the room thermostat fan selector switch should be set on
the “on” position, then the indoor blower would run continuously rather than cycling with the compressor.
GSZ, ASZ, SSZ, DSZ, and VSZ models energize the reversing valve thorough the "O" circuit in the room thermostat.
Therefore, the reversing valve remains energized as long as
the thermostat subbase is in the cooling position. The only
exception to this is during defrost.
For heat pumps, during cooling cycle the reversing valve is
energized as the room thermostat closes “O” terminal to R
and the microprocessor on the UC board responds to such a
condition by energizing the solenoid coil on the reversing
valve.
For communicating room thermostat: When the room thermostat calls for either low stage cool or high stage cool,
appropriate commands are sent via the data 1 and data 2 lines
to the outdoor unit's UC control. The UC control energizes the
on-board compressor relay and the on-board outdoor fan
relay. The compressor high stage solenoid is energized if it
is a high stage call.
The UC control sends a fan command to the indoor unit (air
handler or furnace). The indoor unit operates the indoor
blower at the appropriate airflow level. The system operates
at the cooling level demanded by the thermostat.
61
SYSTEM OPERATION
When the thermostat is satisfied, appropriate commands are
sent to the UC control. The compressor relay and outdoor
fan relay is de-energized. The compressor high stage
solenoid is de-energized if it was energized. The UC control
sends an appropriate command to the indoor unit to deenergize the indoor blower motor.
If room thermostat fan status is set to be “on”, then indoor
blower would run continuously rather than cycling with the
compressor.
For heat pumps, the reversing valve is energized during a
cooling a cycle. The call for cooling from the communicating
thermostat indicates to the control that the reversing valve is
to be energized during cooling operation.
DEFROST CYCLE - LEGACY MODELS
The defrosting of the outdoor coil is jointly controlled by the
defrost control board and the defrost thermostat.
Solid State Defrost Control
During operation the power to the circuit board is controlled
by a temperature sensor, which is clamped to a return bend
(3/8" coils) or a feeder tube (5 mm coils) entering the outdoor
coil. Defrost timing periods of 30, 60, or 90 minutes may be
selected by connecting the circuit board jumper to 30, 60, or
90 respectively. Accumulation of time for the timing period
selected starts when the sensor closes (approximately 31°
F), and when the room thermostat calls for heat. At the end
of the timing period, the unit’s defrost cycle will be initiated
provided the sensor remains closed. When the sensor opens
(approximately 75° F), the defrost cycle is terminated and the
timing period is reset. If the defrost cycle is not terminated
due to the sensor temperature, a ten minute override interrupts the unit’s defrost period. The new upgraded defrost
control has a 12 minute override interrupt.
DEFROST CYCLE - COMFORTNETTM MODELS
The defrosting of the outdoor coil is jointly controlled by the
UC PCB and the outdoor coil temperature (OCT) sensor.
The OCT sensor is clamped to a feeder tube entering the
outdoor coil. Defrost timing periods of 30, 60, 90 or 120
minutes may be selected via the dipswitch settings on the UC
PCB. In a communicating system, the defrost timing periods
can also be selected in the communicating thermostat user
menu. During operation the microprocessor on the UC checks
coil temperature via the OCT sensor every 30, 60, 90, or 120
minutes when there is a call for heating. If by the time the
microprocessor checks the coil temperature, and it's low
enough (approximately 31°F), and if there is a call for heat
from the thermostat, the PCB will initiate a defrost. When the
microprocessor detects the coil temperature to be high
enough (approximately 75 0F), or 10 minutes of maximum
defrost cycle time has elapsed, whichever occurs first, the
defrost cycle is terminated and the timing period is reset. The
field service personnel can also advance a heat pump to the
defrost cycle by simultaneously pressing the “TEST” button
and the “RECALL” button on the UC board.
62
HEATING CYCLE
The reversing valve on the GSZ, SSZ, ASZ and DSZ models
is energized in the cooling cycle through the "O" terminal on
the room thermostat.
These models have a 24 volt reversing valve coil. When the
thermostat selector switch is set in the cooling position, the
"O" terminal on the thermostat is energized all the time.
Care must be taken when selecting a room thermostat. Refer
to the installation instructions shipped with the product for
approved thermostats.
HEATING CYCLE
For legacy room thermostat: When the room thermostat
calls for heat, the contacts of the room thermostat close
making terminals R to Y & G, the low voltage circuit of the
transformer is completed. Current now flows through the
magnetic holding coils of the compressor contactor (CC) and
fan relay (RFC).
This draws in the normally open contact CC, starting the
compressor condenser fan motors. At the same time,
contacts RFC close, starting the indoor fan motor.
When the thermostat is satisfied, it opens its contacts,
breaking the low voltage circuit, causing the compressor
contactor and indoor fan relay to open, shutting down the
system.
If the room thermostat fan selector switch should be set to
the “on” position, then the indoor blower would run continuously rather than cycling with the compressor.

appropriate commands are sent via the data 1 and data 2

energized if it is a high stage call. The UC control sends a
fan command to the indoor unit (air handler or furnace). The
indoor unit operates the indoor blower at the appropriate
airflow level. The system operates at the cooling level
demanded by the thermostat.

AFE18-60A CONTROL BOARD
DESCRIPTION
The AFE18 control is designed for use in heat pump applications where the indoor coil is located above/downstream of a
gas or fossil fuel furnace. It will operate with single and two
stage heat pumps and single and two stage furnaces. The
AFE18 control will turn the heat pump unit off when the
furnace is turned on. An anti-short cycle feature is also
incorporated which initiates a 3 minute timed off delay when
the compressor goes off. On initial power up or loss and
restoration of power, this 3 minute timed off delay will be
initiated. The compressor won’t be allowed to restart until the
3 minute off delay has expired. Also included is a 5 second
de-bounce feature on the “Y, E, W1 and O” thermostat inputs.
These thermostat inputs must be present for 5 seconds
before the AFE18 control will respond to it.
An optional outdoor thermostat, OT18-60A, can be used with
the AFE18 to switch from heat pump operation to furnace
operation below a specific ambient temperature setting, i.e.
break even temperature during heating. When used in this
manner, the “Y” heat demand is switched to the “W1” input
to the furnace by the outdoor thermostat and the furnace is
used to satisfy the first stage “Y” heat demand. On some
controls, if the outdoor thermostat fails closed in this position
during the heating season, it will turn on the furnace during
the cooling season on a “Y” cooling demand. In this
situation, the furnace produces heat and increases the
indoor temperature thereby never satisfying the cooling
demand. The furnace will continue to operate and can only
be stopped by switching the thermostat to the off position or
removing power to the unit and then replacing the outdoor
thermostat. When the AFE18 receives a “Y” and “O”inputfrom the indoor thermostat, it recognizes this as a
cooling demand in the cooling mode. If the outdoor thermostat is stuck in the closed position switching the “Y” demand
to the “W1” furnace input during the cooling mode as
described above, the AFE18 won’t allow the furnace to
operate. The outdoor thermostat will have to be replaced to
restore the unit to normal operation.

2. With voltmeter, check for 24 volts at each heater relay.
Note: BBA/BBC heater relays are DC voltage.
3. No voltage indicates the trouble is in the thermostat or
wiring.
4. Check the continuity of the thermostat and wiring. Repair
or replace as necessary.
NOTE: Consideration must be given to how the heaters are
wired (O.D.T. and etc.). Also safety devices must be checked
for continuity.
S-3B COOLING ANTICIPATOR
The cooling anticipator is a small heater (resistor) in the
thermostat. During the "off" cycle, it heats the bimetal
element helping the thermostat call for the next cooling cycle.
This prevents the room temperature from rising too high
before the system is restarted. A properly sized anticipator
should maintain room temperature within 1 1/2 to 2 degree
range.
The anticipator is supplied in the thermostat and is not to be
replaced. If the anticipator should fail for any reason, the
thermostat must be changed.
S-3C HEATING ANTICIPATOR
The heating anticipator is a wire wound adjustable heater
which is energized during the "ON" cycle to help prevent
overheating of the conditioned space.
The anticipator is a part of the thermostat and if it should fail
for any reason, the thermostat must be replaced. See the
following tables for recommended heater anticipator setting
in accordance to the number of electric heaters installed.
S-3E CTK0*** COMFORTNETTM THERMOSTAT
OVERVIEW
The ComfortNet system (or CT system) is a system that
includes a ComfortNet compatible modular blower and air
conditioner or heat pump with a CTK0* thermostat. Any other
system configurations are considered invalid ComfortNet
CT compatible Air Handler or
Modular Blow er
CT compatible Air Handler or
Modular Blow er
A ComfortNet heating/air conditioning system differs from a
legacy/traditional system in the manner in which the indoor
unit, outdoor unit and thermostat interact with one another.
In a traditional system, the thermostat sends commands to
the indoor and outdoor units via analog 24 VAC signals. It
is a one-way communication path in that the indoor and
outdoor units typically do not return information to the
thermostat.
On the other hand, the indoor unit, outdoor unit, and thermostat comprising a ComfortNet system “communicate” digitally with one another. It is now a two-way communications
path. The thermostat still sends commands to the indoor
and outdoor units. However, the thermostat may also
request and receive information from both the indoor and
outdoor units. This information may be displayed on the CT
thermostat. The indoor and outdoor units also interact with
one another. The outdoor unit may send commands to or
request information from the indoor unit. This two-way digital
communications between the thermostat and subsystems
(indoor/outdoor unit) and between subsystems is the key to
unlocking the benefits and features of the ComfortNet system.
Two-way digital communications is accomplished using
only two wires. The thermostat and subsystem controls are
powered with 24 VAC Thus, a maximum of 4 wires between
the equipment and thermostat is all that is required to
operate the system.

CTK0* WIRING
NOTE: A removable plug connector is provided with the
control to make thermostat wire connections. This plug may
be removed, wire connections made to the plug, and replaced.
It is strongly recommended that multiple wires into a single
terminal be twisted together prior to inserting into the plug
connector. Failure to do so may result in intermittent
operation.
Typical 18 AWG thermostat wire may be used to wire the
system components. However, communications reliability
may be improved by using a high quality, shielded, twisted
pair cable for the data transmission lines. In either case, 100
feet is the maximum length of wire between indoor unit and
outdoor unit, or between indoor unit and thermostat.
FOUR-WIRE INDOORAND OUTDOOR WIRING
Typical wiring will consist of four wires between the indoor
unit and outdoor unit and between the indoor unit and
thermostat. The required wires are: (a) data lines, 1 and 2;
(b) thermostat “R” (24 VAC hot) and “C” (24 VAC common).

S-10A COPELAND COMFORT ALERTTM -
UNITARY (UC) CONTROL DIAGNOSTICS
Applies to ASXC, ASZC, DSXC, and DSZC models
HIGH VO LTAG E!
Disconnect ALL power before servicing
or installing. Multiple power sources
may be present. Failure to do so may
cause property damage, personal injury
or death.
The Copeland Comfort AlertTM diagnostics are fully integrated into the unitary (UC) control. The UC control and
integraged Comfort Alert™ diagnostics provide around-theclock monitoring for common electrical problems, compressor defects and broad system faults. If a problem is detected,
LED indicators flash the proper alert codes to help you
quickly pinpoint the problem.
The diagnostic tables on following pages provide detailed
information regarding the system symptons, indicators (LED
and thermostat), potential problem(s), and corrective actions. The diagnostic information applies to systems wired
as 24VAC traditional (legacy) systems and systems wired as
communicating systems with the CTK0* communicating
thermostat.

S-11 CHECKING LOSS OF CHARGE PROTEC-
TOR
(Heat Pump Models)
The loss of charge protectors senses the pressure in the
liquid line and will open its contacts on a drop in pressure. the
low pressure control will automatically reset itself with a rise
in pressure.
The low pressure control is designed to cut-out (open) at
approximately 21 PSIG. It will automatically cut-in (close) at
approximately 50 PSIG.Test for continuity using a VOM and
if not as above, replace the control.
S-12 CHECKING HIGH PRESSURE CONTROL
HIGH VOLTAGE!
Disconnect A LL power before servicing
or installing. Multiple power sources
may be present. Failure to do so may
cause pr o pe r ty da m a ge , pe r s on al in ju ry
or death.
The high pressure control capillary senses the pressure in the
compressor discharge line. If abnormally high condensing
pressures develop, the contacts of the control open, breaking
the control circuit before the compressor motor overloads.
This control is automatically reset.
1. Using an ohmmeter, check across terminals of high
pressure control, with wire removed. If not continuous,
the contacts are open.
2. Attach a gauge to the dill valve port on the base valve.
With power ON:
WARNING
Line Voltage now present.
3. Start the system and place a piece of cardboard in front
of the condenser coil, raising the condensing pressure.
4. Check pressure at which the high pressure control cutsout. If it cuts-out at 610 PSIG ± 10 PSIG, it is operating
normally (See causes for high head pressure in Service
Problem Analysis Guide). If it cuts out below this pressure
range, replace the control.
S-13 CHECKING LOW PRESSURE CONTROL
The low pressure control senses the pressure in the suction
line and will open its contacts on a drop in pressure. The low
pressure control will automatically reset itself with a rise in
pressure.
The low pressure control is designed to cut-out (open) at
approximately 21 PSIG for heat pumps and 55 PSIG for air
conditioners. It will automatically cut-in (close) at approximately 50 PSIG for heat pumps and 95 PSIG for air
conditioners.
Test for continuity using a VOM and if not as above, replace
the control.
S-15 CHECKING CAPACITOR
CAPACITOR, RUN
A run capacitor is wired across the auxiliary and main
windings of a single phase permanent split capacitor motor.
The capacitors primary function is to reduce the line current
while greatly improving the torque characteristics of a motor.
This is accomplished by using the 90° phase relationship
between the capacitor current and voltage in conjunction
with the motor windings, so that the motor will give two phase
operation when connected to a single phase circuit. The
capacitor also reduces the line current to the motor by
improving the power factor.
The line side of this capacitor is marked with "COM" and is
wired to the line side of the circuit.
CAPACITOR, START
SCROLL COMPRESSOR MODELS
In most cases hard start components are not required on
Scroll compressor equipped units due to a non-replaceable
check valve located in the discharge line of the compressor.
However, in installations that encounter low lock rotor voltage, a hard start kit can improve starting characteristics and
reduce light dimming within the home. Only hard start kits
approved by Amana® brand or Copeland should be used.
"Kick Start" and/or "Super Boost" kits are not approved start
assist devices.
The discharge check valve closes off high side pressure to
the compressor after shut down allowing equalization through
the scroll flanks. Equalization requires only about 1/2 second.
To prevent the compressor from short cycling, a Time Delay
Relay (Cycle Protector) has been added to the low voltabe
circuit.
