Matching 569J*08G/H Model to Evaporator
Coil
The Model 569J*08G/H are a single-circuit. two--stage
unit design, requiring one set of refrigeration piping.
.INSTALLATION
Jobsite Survey
Complete the following checks before installation.
1. Consult local building codes and the NEC (National
Electrical Code) ANSI/NFPA 70 for special installa-
tion requirements.
2. Determine unit location (from project plans) or select
unit location.
3. Check for possible overhead obstructions which may
interfere with unit lifting or rigging.
Step 1 — Plan for Unit Location
The 569J units are designed and approved for outdoor
installation only. Do not locate these units indoors. Do not
add ducting to unit fan system.
Select a location for the unit and its support system (pad,
rails or other) that provides for the minimum clearances
required for safety. This includes the clearance to
combustible surfaces, unit performance and service access
below, around and above unit as specified in unit drawings.
See Fig. 4.
NOTE: Local codes may require different clearances
than specified in Fig. 4. It is the responsibility of installers
to be knowledgeable in local codes and to modify the
recommended clearances to satisfy local codes.
NOTE: Consider also the effect of adjacent units on
airflow performance and control box safety clearance.

Fig. 3 -- Service Clearance Dimensional Drawing
Do not install the outdoor unit in an area where fresh air
supply to the outdoor coil may be restricted or when
recirculation from the condenser fan discharge is possible.
Do not locate the unit in a well or next to high walls.
Evaluate the path and required line length for
interconnecting refrigeration piping, including suction
riser requirements (outdoor unit above indoor unit), liquid
line lift (outdoor unit below indoor unit) and hot gas
bypass line. Relocate sections to minimize the length of
interconnecting tubing.
DO NOT BURY REFRIGERATION LINES.
Although unit is weatherproof, avoid locations that permit
water from higher level runoff and overhangs to fall onto
the unit.
Step 2 — Complete Pre-Installation Checks
Check Unit Electrical Characteristics: Confirm before
installation of unit that voltage, amperage and circuit
protection requirements listed on unit data plate agree with
power supply provided.
Un--crate Unit: Remove unit packaging except for the top
skid assembly, which should be left in place until after the
unit is rigged into its final location.
Inspect Shipment: File a claim with shipping company if
the shipment is damaged or incomplete.
Consider System Requirements:
SConsult local building codes and National Electrical Code
(NEC, U.S.A.) for special installation requirements.
SAllow sufficient space for airflow clearance, wiring,
refrigerant piping, and servicing unit. See Fig. 2 for unit
dimensions and weight distribution data.
SLocate the unit so that the outdoor coil (condenser)
airflow is unrestricted on all sides and above.
SThe unit may be mounted on a level pad directly on the
base channels or mounted on raised pads at support
points. See Tables 1 and 2 for unit operating weights.
See Fig. 2 for weight distribution based on
recommended support points.
NOTE: If vibration isolators are required for a particular
installation, use the data in Fig. 2 to make the proper
selection.
Step 3 — Prepare Unit Mounting Support
Slab Mount —
Provide a level concrete slab that extends a minimum of 6
in. (150 mm) beyond unit cabinet. Install a gravel apron in
front of condenser coil air inlet to prevent grass and
foliage from obstructing airflow.
Step 4 — Rig and Mount the Unit
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage.
All panels must be in place when rigging. Unit is not
designed for handling by fork truck.
CAUTION
!
Rigging: These units are designed for overhead rigging.
Refer to the rigging label for preferred rigging method.
569J*08G/H

7
Spreader bars are required. Use the wooden top skid,
when rigging, to prevent rigging straps from damaging the
unit. All panels must be in place when rigging. As further
protection for coil faces, plywood sheets may be placed
against the sides of the unit, behind cables. Run cables to
a central suspension point so that the angle from the
horizontal is not less than 45 degrees. Raise and set the
unit down carefully.
If it is necessary to roll the unit into position, mount the
unit on longitudinal rails, using a minimum of 3 rollers.
Apply force to the rails, not the unit. If the unit is to be
skidded into position, place it on a large pad and drag it
by the pad. Do not apply any force to the unit.
Raise from above to lift the unit from the rails or pad
when unit is in its final position.
After the unit is in position, remove all shipping materials
and top crating.
Step 5 — Determine Refrigerant Line Sizes
Select the recommended line sizes for the 569J*08G/H
unit from the Table 3.
Determine the linear length of interconnecting piping
required between the outdoor unit and indoor unit
(evaporator). Consider and identify also the arrangement
of the tubing path (quantity and type of elbows in both
lines), liquid line solenoid size, filter drier and any other
refrigeration specialties located in the liquid line. Refer to
the indoor unit installation instructions for additional
details on refrigeration specialties devices.
Determine equivalent line length adjustments for path and
components and add to linear line lengths. See Table 4,
Equivalent Lengths for Common Fittings, for usual fitting
types. Also identify adjustments for refrigeration
specialties. Contact Bryant Applications Engineering for
additional data and information on equivalent lengths.

NOTE: Equivalent line lengths will vary based on tube
diameter. Calculate equivalent line length for each pipe by
adding equivalent length adjustments to linear lengths for
each pipe.
Liquid Lift —
A liquid lift condition exists when the outdoor unit is located
below the indoor (evaporator) unit and liquid flows vertically
up in a portion of the liquid line. The vertical column of
liquid reduces the available state point subcooling at the
evaporator coil’s thermal expansion valve. This effect
reduces the length of liquid lift (feet of elevation) that a
liquid line size can accommodate. Longer linear tube lengths
will also reduce the amount of liquid lift possible.
Check Table 3 for maximum liquid lift capabilities for line
sizes. Reselect the liquid line tube size if necessary. If
maximum available tube size cannot provide the required lift
distance on this installation, relocate the outdoor unit to
reduce the equivalent line length or the lift requirement.
Suction Riser —
A suction riser condition exists when the outdoor unit is
located above the indoor (evaporator) unit and suction
vapor must flow vertically up to return to the compressor.
Oil return is a concern when the suction tube size is too
large to produce the minimum refrigerant velocity to
ensure oil return at minimum load conditions.
Check Table 5 for maximum suction tube size for
569J*08G/H units at minimum load conditions. Consider
suction speed riser (reduced tube size for vertical segment
only) (see Fig. 4) or double suction riser arrangement (see
Fig. 5) if the planned suction tube size does not provide
necessary minimum flowrates for this riser.

Vertical Separation (outdoor unit above indoor unit) –
Vertical elevation difference of 200 ft (60 m) is permitted
when the outdoor unit (569J) is located above the indoor
unit.
Step 6 — Complete Refrigerant Piping Connections
IMPORTANT: Do not bury refrigerant piping
underground.
IMPORTANT: A refrigerant receiver is not provided
with the unit. Do not install a receiver.
Provide Safety Relief —
If local codes dictate an additional safety relief device,
purchase locally and install locally. Installation will
require the recovery of the factory shipping charge before
the factory tubing can be cut and the supplemental relief
device is installed.

Check 569J*08G/H Model with Evaporator Coil
Connections —
Confirm before installation of unit that the evaporator coil
connections are consistent with the 569J*08G/H.
Insulate Suction Lines —
Apply closed-cell tubular insulation to all suction lines
between evaporator coil connection and 569J*08G/H
unit’s suction service valve.
Refer to Table 6 for recommendations on refrigeration
specialties.
Select the filter drier for maximum unit capacity and
minimum pressure drop. Complete the refrigerant piping
from the indoor unit to the outdoor unit before opening
the liquid and suction lines at the outdoor unit.
Install Liquid Line Solenoid Valve —
It is recommended that a solenoid valve be placed in the
main liquid line (see Fig. 6) between the condensing unit
and the evaporator coil. Locate the solenoid valve at the
outlet end of the liquid line, near the evaporator coil
connections, with flow direction arrow pointed at the
evaporator coil. Refer to Table 6. (A liquid line solenoid
valve is required when the liquid line length exceeds 75 ft
[23 m].) This valve prevents refrigerant migration (which
causes oil dilution) to the compressor during the off cycle, at
low outdoor ambient temperatures. Wire the solenoid in
parallel with the compressor contactor coil (see Fig. 6). This
means of electrical control is referred to as solenoid drop
control.

Solenoid drop control wiring: Control the power to the
liquid line solenoid through a Solenoid Valve Relay (SVR)
in all units. Use part number HN61PC005 (field--supplied,
installed). 569J*08G/H unit requires one SVR.
Evaporator Capacity Control Liquid Line Solenoid
Val ve: Many older unit designs included automatic
capacity controls that sensed changes in suction pressure
and could increase or decrease compressor capacity
automatically as the evaporator load changed. Control
systems were used on these units that had the thermostat’s
second stage contacts control a capacity control liquid line
solenoid valve to open or shutoff a portion of the
evaporator surface without any direct connection to the
compressor circuit.
This form of system capacity staging control is not
possible with 569J models. If this installation is a retrofit
for a unit that included automatic pressure--operated
unloading, check the existing thermostat and liquid
solenoid valve. When found, convert the evaporator
second stage solenoid control into a drop--solenoid
control.
Selecting an Accumulator –
Because all 569J models use scroll compressors, an
accumulator is not required. If an accumulator is to be
added, check the accumulator manufacturer’s literature
carefully for indication of its suitability for use with
R--410A; look for minimum working pressure of 200 psig
(1380 kPa). Select the accumulator first on the basis of its
cataloged minimum capacity (tons) to ensure oil return from
the accumulator, then on tube size or holding capacity.
Make Piping Connections —
Piping connections at the 569J unit are ball valves with
stub tube extensions. Do not open the unit service valves
until all interconnecting tube brazing has been completed.
The stub tube connections include 1/4-in SAE service fittings
with Schrader valve cores (see Fig. 7). Before making any
brazed connections to the unit service valves, remove both
Schrader valve caps and cores and save for re-installation.
Connect a source for nitrogen to one of these service fittings
during tube brazing to prevent the formation of copper
oxides inside the tubes at brazed joints.
When connecting the field tubing to the 569J service
valves, wrap the valves in wet rags to prevent overheating.
Pressure-test all joints from outdoor unit connections over
to the evaporator coil, using nitrogen as pressure and with
soap-and-bubbles.
When pressure-testing is completed, remove the nitrogen
source at the outdoor unit service valves and re-install the
two Schrader valve cores. Torque the cores to 2-3 in-lbs
(23-34 N-cm).

Evacuation/Dehydration —
Evacuate and dehydrate the connected refrigeration
system(s) (excluding the 569J*08G/H unit) to 500 microns
using a two-stage vacuum pump attached to the service
ports outside the 569J service valves, following
description in GTAC II, Module 4, System Dehydration.
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could cause personal
injury, death and/or equipment damage.
PuronR(R--410A) refrigerant systems operate at
higher pressure than standard R--22 systems. Do not
use R--22 service equipment or components on Puron
refrigerant equipment.
!WARNING
This unit is designed for use with Puron (R--410A)
refrigerant. Do not use any other refrigerant in this system.
Puron (R--410A) refrigerant is provided in pink (rose)
colored cylinders. These cylinders are available with and
without dip tubes; cylinders with dip tubes will have a
label indicating this feature. For a cylinder with a dip
tube, place the cylinder in the upright position (access
valve at the top) when removing liquid refrigerant for
charging. For a cylinder without a dip tube, invert the
cylinder (access valve on the bottom) when removing
liquid refrigerant.
Because Puron (R--410A) refrigerant is a blend, it is strongly
recommended that refrigerant always be removed from the
cylinder as a liquid. Admit liquid refrigerant into the system
in the discharge line. If adding refrigerant into the suction
line, use a commercial metering/expansion device at the
gauge manifold; remove liquid from the cylinder, pass it
through the metering device at the gauge set and then pass it
into the suction line as a vapor. Do not remove Puron
(R--410A) refrigerant from the cylinder as a vapor.
Preliminary Charge —
Before starting the unit, charge R-410A liquid refrigerant
into the high side of each 569J circuit through the liquid
service valve(s). The amount of refrigerant added must be
at least 80% of the operating charge listed in Table 3 for
LINEAR line length LESS the factory charge quantity (if
factory shipping charge has not been removed). See
example below.
Allow high and low side pressures to equalize. If pressures
do not equalize readily, charge R-410A vapor (using spe-
cial service manifold with expansion device) into the suc-
tion line service port for the low side of system to assure
charge in the evaporator. Refer to GTAC II, Module 5,
Charging, Recover, Recycling, and Reclamation for liquid
charging procedures.
Example:
569J*08G/H (RTPF)
60-ft (18.3 m) linear line length
Equivalent line length 90-ft (27.4 m)
Liquid Lift: 20-ft (6.1 m)
Select line sizes from Table 3 (569J):
Liquid 1/2in
Suction 1 1/8in.
Charge 22.5 lbs (at 75--ft linear length)
80% of Operating Charge:
0.80 x 22.5 = 18 lbs
Factory Shipping Charge: 14 lbs
Field-Charge quantity: 18 -- 14 = 4 lbs
For linear line lengths longer than 125 ft (38 m), contact
your local Bryant representative for system charge value.

Non--Fused Disconnect —
When installing units, provide a disconnect switch per NEC
(National Electrical Code) of adequate size. Disconnect
sizing data is provided on the unit informative plate. Locate
on unit cabinet or within sight of the unit per national or
local codes. Do not cover unit informative plate if mounting
the disconnect on the unit cabinet.
All Units —
All field wiring must comply with NEC and all local
codes. Size wire based on MCA (Minimum Circuit Amps)
on the unit informative plate. See Fig. 9 and the unit label
diagram for power wiring connections to the unit power
terminal blocks and equipment ground. Maximum wire
size is #2 ga AWG (copper only) per pole on contactors.
Provide a ground-fault and short-circuit over-current
protection device (fuse or breaker) per NEC Article 440
(or local codes). Refer to unit informative data plate for
MOCP (Maximum Over-current Protection) device size.
All field wiring must comply with the NEC and local
requirements.
All units except 208/230-v units are factory wired for the
voltage shown on the nameplate. If the 208/230-v unit is to
be connected to a 208-v power supply, the control
transformer must be rewired by moving the black wire with
the

-in. female spade connector from the 230-v connection
and moving it to the 208-v

-in. male terminal on the
primary side of the transformer. Refer to unit label diagram
for line-side information. Field power wires will be
connected line--side pressure lugs on the power terminal
block or at factory--installed option non--fused disconnect.
NOTE: Check all factory and field electrical connections
for tightness.
Affix the crankcase heater warning sticker to the unit
disconnect switch.
Voltage and Current Balance —
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate. See
Table 7. On 3-phase units, voltages between phases must
be balanced within 2% and the current within 10%. Use
the formula shown in the legend for Table 7, Note 4 (see
page 15) to determine the percent of voltage imbalance.
Operation on improper line voltage or excessive phase
imbalance constitutes abuse and may cause damage to
electrical components. Such operation would invalidate
any applicable Bryant warranty.
Convenience Outlets —
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Units with convenience outlet circuits may use
multiple disconnects. Check convenience outlet for
power status before opening unit for service. Locate
its disconnect switch, if appropriate, and open it.
Tag-out this switch, if necessary.
!WARNING
Two types of convenience outlets are offered on 569J
models: Non-powered and unit-powered. Both types
provide a 125-volt GFCI (ground-fault circuit-interrupter)
duplex receptacle rated at 15-A behind a hinged
waterproof access cover, located on the end panel of the
unit. See Fig. 12.

Non-powered type: This type requires the field
installation of a general-purpose 125-volt 15-A circuit
powered from a source elsewhere in the building. Observe
national and local codes when selecting wire size, fuse or
breaker requirements and disconnect switch size and
location. Route 125-v power supply conductors into the
bottom of the utility box containing the duplex receptacle.
Maximum continuous current for this type of convenience
outlet (non--unit powered) must not exceed 8 Amps.
Unit-powered type: A unit-mounted transformer is
factory-installed to stepdown the main power supply voltage to
the unit to 115-v at the duplex receptacle. This option also
includes a manual switch with fuse, located in a utility box and
mounted on a bracket behind the convenience outlet; access is
through the unit’s control box access panel. See Fig. 12.
The primary leads to the convenience outlet transformer are
not factory-connected. Selection of primary power source is
a customer-option. If local codes permit, the transformer
primary leads can be connected at the line-side terminals on
the unit-mounted non-fused disconnect or HACR breaker
switch; this will provide service power to the unit when the
unit disconnect switch or HACR switch is open. Other
connection methods will result in the convenience outlet
circuit being de-energized when the unit disconnect or
HACR switch is open. See Fig. 13.

Using unit-mounted convenience outlets: Units with
unit-mounded convenience outlet circuits will often
require that two disconnects be opened to de-energize
all power to the unit. Treat all units as electrically
energized until the convenience outlet power is also
checked and de-energization is confirmed. Observe
National Electrical Code Article 210, Branch Circuits,
for use of convenience outlets.
!WARNING
Installing Weatherproof Cover: A weatherproof while in
use cover for the factory installed convenience outlets is
now required by UL standards. This cover cannot be
factory mounted due its depth; it must be installed at unit
installation. For shipment, the convenience outlet is
covered with a blank cover plate.
The weatherproof cover kit is shipped in the unit’s control
box. The kit includes the hinged cover, a backing plate
and gasket.
DISCONNECT ALL POWER TO UNIT AND

4. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply
voltage is greater than 2%. Use the following formula to de-
termine the percentage of voltage imbalance.
Example: Supply voltage is 230-3-60
% Voltage Imbalance = 100 x

= 227
Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.
Determine percent of voltage imbalance.

= 1.76%
This amount of phase imbalance is satisfactory as it is below the
maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than
2%, contact your local electric utility company immediately.

Step 9 — Wind Baffles for Low Ambient Control
569J*08H includes the factory installed 32LT Motormaster
Low Ambient Control.
Units with 32LT Motormaster control require the addition
of wind baffles to ensure full range low ambient
operation. Material data and dimensions for wind baffles
are included in the Appendix C section, Low Ambient
Control, starting on page 29. Fabricate the wind baffles
and mount per instructions.
PRE-START-UP
IMPORTANT: Before beginning Pre-Start-Up or
Start-Up, review Start-Up Checklist at the back of this
book. The Checklist assures proper start-up of a unit
and provides a record of unit condition, application
requirements, system information, and operation at
initial start-up.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage.
Do not attempt to start the condensing unit, even
momentarily, until the following steps have been
completed. Compressor damage may result.
CAUTION
!
System Check
1. The electrical power source must agree with the unit’s
nameplate rating.
2. Check all air handler(s) and other equipment auxiliary
components. Consult the manufacturer’s instructions re-
garding any other equipment connected to the condens-
ing unit. If the unit has field-installed accessories, be
sure all are properly installed and correctly wired. If
used, the airflow switch must be properly installed.
3. Check tightness of all electrical connections.
4. Be sure liquid line and low side of the system are
properly leak checked and dehydrated.
5. Be sure the unit is properly charged. See “Preliminary
Charge”, below.
6. Open the liquid line and suction line service valves.
7. The crankcase heater must be firmly attached to the
compressor crankcase. Be sure the crankcase is warm
(heater must be on for 24 hours before starting
compressor).
Turn On Crankcase Heater —
Turn on the crankcase heater for 24 hours before starting
the unit to be sure all the refrigerant is out of the oil.To
energize the crankcase heater, proceed as follows:
1. Set the space thermostat set point above the space
temperature so there is no demand for cooling.
2. Close the field disconnect.
Preliminary Charge —
Before starting the unit, charge liquid refrigerant into the
high side of the system through the liquid service valve. The
amount of refrigerant added must be at least 80% of the
operating charge listed in the Physical Data table (Tables 1
and 2 on page 5). Allow high and low side pressures to
equalize before starting compressor. If pressures do not
equalize readily, charge vapor on low side of system to
assure charge in the evaporator. Refer to GTAC II, Module
5, Charging, Recover, Recycling, and Reclamation for liquid
charging procedures.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage.
Prior to starting compressor, a preliminary charge of
refrigerant must be added to avoid possible
compressor damage.
CAUTION
!
START-UP
569J Units: The compressor crankcase heater must be on
for 24 hours before start-up. After the heater has been on
for 24 hours, the unit can be started. If no time elapsed
since the preliminary charge step was completed, it is
unnecessary to wait the 24-hour period.
Preliminary Checks
1. Check that electric power supply agrees with unit
nameplate data.
2. Verify that the compressor crankcase heater is se-
curely in place.
3. Check that the compressor crankcase heater has been
on at least 24 hours.
4. Recheck for leaks using the procedure outlined in the
Pre-Start-Up section, Leak Test and Dehydration. If
any leaks are detected, repair as required. Evacuate
and dehydrate as described in the Leak Test and De-
hydration section.
5. Ensure that the preliminary charge has been added as
described in the Pre-Start-Up section, Preliminary
Charge.
6. All internal wiring connections must be tight, and all
barriers and covers must be in place.
NOTE: The 569J units are factory charged with the
required amount of oil. If recharging in required, use
Emkarate RL 32-3MAF for the 569J units.
Compressor Rotation —
On 3--phase units with scroll compressors, it is important to
be certain that the compressor is rotating in the proper
direction. 569J units are equipped with a Comfort Alert
Diagnostic Module (CADM). Alert Code 7 indicates reverse
power phasing.
569J*08G/H

17
To correct phase order:
1. Turn off power to the unit, tag disconnect.
2. Reverse any two of the unit power leads.
3. Reapply power to the compressor, verify correct
pressures.
To verify the compressor is rotating in the proper
direction:
1. Connect service gages to the suction and liquid pres-
sure fittings.
2. Energize the compressor.
3. The suction pressure should drop and the liquid
pressure should rise, as is normal on any start--up.
Compressor Overload —
This overload interrupts power to the compressor when
either the current or internal motor winding temperature
becomes excessive, and automatically resets when the
internal temperature drops to a safe level. This overload
may require up to 60 minutes (or longer) to reset. If the
internal overload is suspected of being open, disconnect
the electrical power to the unit and check the circuit
through the overload with an ohmmeter or continuity
tester.
Advanced Scroll Temperature Protection (ASTP) —
A label located above the terminal box identifies Copeland
Scroll compressor models that contain this technology. See
Fig. 17. Advanced Scroll Temperature Protection (ASTP) is
a form of internal discharge temperature protection, that
unloads the scroll compressor when the internal temperature
reaches approximately 149_C (300_F). At this temperature,
an internal bi--metal disk valve opens and causes the scroll
elements to separate, which stops compression. Suction and
discharge pressures balance while the motor continues to
run. The longer the compressor runs unloaded, the longer it
must cool before the bi--metal disk resets. See Fig. 18.
To manually reset ASTP, the compressor should be
stopped and allowed to cool. If the compressor is not
stopped, the motor will run until the motor protector trips,
which occurs up to 90 minutes later. Advanced Scroll
Temperature Protection will reset automatically before the
motor protector resets, which may take up to 2 hours.

be energized.
Reset the space thermostat below ambient so that a call
for cooling is ensured.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage.
Never charge liquid into the low-pressure side of
system. Do not overcharge. During charging or
removal of refrigerant, be sure indoor-fan system is
operating. Ensure both outdoor fan motors are
running; bypass any Motormaster function.
CAUTION
!
Adjust Refrigerant Charge —
Refer to Cooling Charging Chart, Fig. 19. For applications
with line lengths greater than 125 ft (38 m), contact Bryant
representative. Vary refrigerant until the conditions of the
chart are met. Note that the charging charts are different
from the type normally used. The charts are based on
charging the units to the correct subcooling for the various
operating conditions. Accurate pressure gage and
temperature sensing device are required. Connect the
pressure gage to the service port on the liquid line service
valve. Mount the temperature sensing device on the liquid
line close to the liquid line service valve, and insulate it so
that outdoor ambient temperature does not affect the reading.
Indoor airflow must be within the unit’s normal operating
range. Operate the unit for a minimum of 15 minutes.
Ensure that pressure and temperature readings have
stabilized. Plot the liquid pressure and temperature on chart
and add or reduce the charge to meet the curve. Adjust the
charge to conform with the charging chart, using the liquid
pressure and temperature to read the chart.

OPERATING SEQUENCE
Base Unit Controls
Indoor (Supply) Fan —
The indoor fan contactor (IFC) is remotely located at the fan
coil or fan section. If the thermostat fan operation is selected
as Continuous, the IFC is energized and the indoor (supply)
fan motor runs continuously. If the thermostat fan operation
is selected as Automatic, the IFC will be energized on a call
for Cooling; indoor (supply) fan motor runs. When
thermostat call for Cooling is satisfied, the IFC is
de-energized and indoor (supply) fan motor stops.
Cooling, Unit Without Economizer —
On a thermostat call for Cooling, IFC will be energized
and indoor (supply) fan motor runs. Thermostat output Y1
is energized; terminal Y1 at 569J unit receives 24-v. 24-v
received at CADM1 terminal Y. If anti-recycle time delay
period has not expired, CADM1 relay will remain open,
de-energizing Solenoid Valve Relay (SVR) and preventing
compressor start. When safety pressure switches are
closed and CADM1 time delay expires, CADM1 relay
closes, SVR and compressor contactor C1 are energized;
Compressor Relay Timer (CTR) is closed and Digital
Cycle Timer (CTD) is energized commanding Digital
Compressor Solenoid (DCS) on, liquid line solenoid valve
LLSV opens, all outdoor fan motors start and Compressor
starts part load operation.
On thermostat call for Stage 2 Cooling, thermostat output
Y2 is energized CTR receives 24--v at terminal 1 changing
contacts to open. CTD is de--energized and commands
DCS off, Compressor operates at full load.
As space cooling load is satisfied, thermostat outputs Y2 and
Y1 are sequentially de--energized, removing 24--v at 569J
terminals Y1 and Y2. Compressor resumes part load
operation on Y2 opening. On Y1 opening, Compressor 1
stops, all outdoor fan motors stop and SVR is de--energized.
Liquid Line solenoid valve is de--energized and valve closes.
CADM1 begins its three--minute anti--recycle time delay.
If either the Low Pressure Switch or High Pressure Switch
opens while thermostat output Y1 or Y2 remain energized,
the compressor contactor is de-energized, the compressor
stops and liquid line solenoid is de-energized (valve
closes). CADM initiates a TRIP event (cooling demand
sensed at CADM terminal Y but no current is measured at
T1, T2, T3 motor sensors); CADM relay opens and RED
LED is illuminated. TRIP condition maintains lockout of
compressor operation until CADM is manually reset.
Reset CADM by cycling unit main power.
Complete system shutdown may be caused by loss of
main power, open compressor internal overload, open
low-pressure or high-pressure switch, or a fault detected
by the CADM logic. Compressor operation without
cooling may indicate the compressor’s ASTP feature is
active; disconnect unit power and allow compressor to
cool. See Service section for further details.
Cooling, Unit With Economizer —
Refer to fan coil unit installation instructions and
economizer accessory installation instructions for
operating sequences when system is equipped with
accessory economizer.
Heating —
Refer to fan coil unit installation instructions and accessory
heating device installation instructions for operating
sequences in heating mode.
ROUTINE SYSTEM MAINTENANCE
These items should be part of a routine maintenance
program, to be checked every month or two, until a specific
schedule for each can be identified for this installation:
