EVALUATING MOTOR SPEED
The direct drive ECM blower motor uses a constant speed design.
Motor speed is controlled by a 0-10 vdc signal, where 10 vdc is
equal to motor’s maximum rpm.
SELECTING FAN SPEED
All units come factory set for 9.0 vdc or approximately 90% of the
motor’s maximum speed. Fan speed should be set per job specifi-
cation cfm (cubic feet per minute) and ESP (external static pres-
sure) required and per Fan speed set up label included on the unit’s
high voltage cover. In some cases, the Fan Speed Set Up label may
already include the field setting if unit was previously installed.
Check the box on the lower half of the label to see if the field volt-
age setting was filled in and if so, set fan speed to that voltage.
Otherwise see detailed instructions below.
NOTE: Fan Speed Set-Up is for full load airflow. All 582K*08-16
units have multiple speeds of fan control. Low cool and ventila-
tion will operate at lower fan rpms. This offset is factory set and
controlled by the UCB. If fan speed verification is being done with
a strobe, fan speed should be verified in all unit operation modes.
Units with Electro-mechanical controls
The Fan Speed set up controls are located on the lower section of
the Unit Control Board (UCB). See Fig. 9 for location.
1. Check the job specifications for the cfm (cubic feet per
minute) and ESP (external static pressure) required.
2. Using the chart on the Fan Speed Set Up labels (see Fig. 10),
calculate the vdc from the cfm and ESP for the base.
3. If installing any accessories listed at the bottom of the Set
Up Label, add accessory vdc to base unit vdc in upper por-
tion of label.
NOTE: The Fan Speed Set Up labels are located on the High
Voltage cover in the Control Box.
4. Connect a multimeter to the vdc terminals on the UCB.
5. Set the Range Switch to either A, B, or C per the Switch
Range table.
6. Using a straight blade screwdriver turn the vdc control dial
to fine tune the vdc reading.
7. Record the reading in the Field Setting field.
NOTE: For units equipped with the Perfect Humidity™ option,
when replacing the UCB cut JMP 1,2 and 3 in the REHEAT/HP
section of the replacement UCB.

TROUBLESHOOTING THE ECM MOTOR
Axion™ Fan Technology motors are designed with several built-
in protections included in the motor software. If the motor detects
a fault it will safely shut down. See Table 5, “Supply Fan Motor
Logic and Safety Relays” on page 36 for a complete list.
Troubleshooting the motor requires a voltmeter.
1. Disconnect main power to the unit.
2. Disconnect motor plug in supply section of the unit.
3. Restore main unit power.
4. Check for proper line voltage at motor power leads Black
(PL1-3), Yellow (PL1-6), and Blue (PL1-9).
5. Disconnect main power.
6. Reconnect motor plug in supply section of unit.
7. Restore main power.
8. Check for proper motor control voltage signal of 9.7 vdc to
10.3 vdc at IFM-1 and IFM-3 on Unit Control Board
(UCB). See Fig. 11.
9. Using a jumper wire from unit control terminals R to G,
engage motor operation.
10. Verify control signal from user speed selection switch by
placing voltmeter taps in provided terminals marked vdc.
Signal should be between 3.8 vdc and 10.3 vdc.

quence with the unit’s ventilation, cooling, and heating operation.
See Table 1 for fan operation for various modes.
COOLING
Condenser Coil
The condenser coil is fabricated with round tube copper hairpins
and plate fins of various materials and/or coatings (see Model
Number Nomenclature in Appendix A to identify the materials
provided in this unit). The coil may be one-row or composite-type
two-row. Composite two-row coils are two single-row coils fabri-
cated with a single return bend end tubesheet.
Condenser Coil Maintenance and Cleaning
Recommendation
Routine cleaning of coil surfaces is essential to maintain proper
operation of the unit. Elimination of contamination and removal of
harmful residues will greatly increase the life of the coil and ex-
tend the life of the unit. The following maintenance and cleaning
procedures are recommended as part of the routine maintenance
activities to extend the life of the coil.
REMOVE SURFACE LOADED FIBERS
Surface loaded fibers or dirt should be removed with a vacuum
cleaner. If a vacuum cleaner is not available, a soft non-metallic
bristle brush may be used. In either case, the tool should be ap-
plied in the direction of the fins. Coil surfaces can be easily dam-
aged (fin edges can be easily bent over and damage to the coating
of a protected coil) if the tool is applied across the fins.
NOTE: Use of a water stream, such as a garden hose, against a
surface loaded coil will drive the fibers and dirt into the coil. This
will make cleaning efforts more difficult. Surface loaded fibers
must be completely removed prior to using low velocity clean wa-
ter rinse.
PERIODIC CLEAN WATER RINSE
A periodic clean water rinse is very beneficial for coils that are ap-
plied in coastal or industrial environments. However, it is very im-
portant that the water rinse is made with a very low velocity water
stream to avoid damaging the fin edges. Monthly cleaning as de-
scribed below is recommended. Rinsing coils in the opposite di-
rection of airflow is recommended.
ROUTINE CLEANING OF COIL SURFACES
Periodic cleaning with Totaline®environmentally balanced coil
cleaner is essential to extend the life of coils. This cleaner is avail-
able from Replacement Components Division as P/N: P902-0301
for a one gallon container, and P/N: P902-0305 for a 5 gallon con-
tainer. It is recommended that all coils, including standard alumi-
num, pre-coated, copper/copper or e-coated coils be cleaned with
the Totaline environmentally balanced coil cleaner as described
below. Coil cleaning should be part of the unit’s regularly sched-
uled maintenance procedures to ensure long life of the coil. Failure
to clean the coils may result in reduced durability in the environ-
ment.
Avoid use of:
• coil brighteners
• acid cleaning prior to painting
• high pressure washers
• poor quality water for cleaning
Totaline environmentally balanced coil cleaner is nonflammable,
hypo-allergenic, non-bacterial, and a USDA accepted biodegrad-
able agent that will not harm the coil or surrounding components
such as electrical wiring, painted metal surfaces, or insulation. Use
of non-recommended coil cleaners is strongly discouraged since
coil and unit durability could be affected.
Clean coil as follows:
1. Turn off unit power, tag disconnect.
2. Remove all screws from the top panel except the screws
securing the condenser fan to the top panel. See Fig. 18.
Fig. 18 — Location of Screws and Coil Corner Post
3. Remove condenser coil corner post. See Fig. 18. To hold
top panel open, place coil corner post between top panel
and center post. See Fig. 19.

CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced unit
performance or unit shutdown.
High velocity water from a pressure washer or garden hose,
or compressed air should never be used to clean a coil. The
force of the water or air jet will bend the fin edges and
increase airside pressure drop.
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in accelerated
corrosion of unit parts.
Harsh chemicals, household bleach or acid or basic
cleaners should not be used to clean outdoor or indoor coils
of any kind. These cleaners can be very difficult to rinse out
of the coil and can accelerate corrosion at the fin/tube
interface where dissimilar materials are in contact. If there
is dirt below the surface of the coil, use the Totaline
environmentally balanced coil cleaner.

6. Hold garden sprayer nozzle close to finned areas and apply
cleaner with a vertical, up-and-down motion. Avoid spraying
in horizontal pattern to minimize potential for fin damage.
7. Ensure cleaner thoroughly penetrates deep into finned areas.
Interior and exterior finned areas must be thoroughly cleaned.
Finned surfaces should remain wet with cleaning solution for
10 minutes. Ensure surfaces are not allowed to dry before
rinsing. Reapply cleaner as needed to ensure 10-minute
saturation is achieved.
8. Thoroughly rinse all surfaces with low velocity clean water
using downward rinsing motion of water spray nozzle.
Protect fins from damage from the spray nozzle.
Evaporator Coil
Cleaning the Evaporator Coil
1. Turn unit power off. Install lockout tag. Remove evapora-
tor coil access panel.
2. If economizer or two-position damper is installed, remove
economizer by disconnecting Molex®1 plug and removing
mounting screws.
3. Slide filters out of unit.
4. Clean coil using a commercial coil cleaner or dishwasher
detergent in a pressurized spray canister. Wash both sides
of coil and flush with clean water. For best results, back-
flush toward return-air section to remove foreign material.
Flush condensate pan after completion.
5. Reinstall economizer and filters.
6. Reconnect wiring.
7. Replace access panels.
Evaporator Coil Metering Devices
582K*08-16 units with or without the Perfect Humidity™ op-
tion use a TXV-distributer system.
THERMOSTATIC EXPANSION VALVE (TXV)
The TXV is a bi-flow, bleed port expansion valve with an external
equalizer. The TXVs are specifically designed to operate with
Puron®refrigerant. Use only factory-authorized TXVs.
TXV Operation
The TXV is a metering device that is used in air conditioning and
heat pump systems to adjust to the changing load conditions by
maintaining a preset superheat temperature at the outlet of the
evaporator coil.
The volume of refrigerant metered through the valve seat is de-
pendent upon the following:
1. Superheat temperature is sensed by cap tube sensing bulb
on suction tube at outlet of evaporator coil. This tempera-
ture is converted into pressure by refrigerant in the bulb
pushing downward on the diaphragm, which opens the
valve using the push rods.
2. The suction pressure at the outlet of the evaporator coil is
transferred through the external equalizer tube to the
underside of the diaphragm.
3. The pin is spring loaded, which exerts pressure on the under-
side of the diaphragm. Therefore, the bulb pressure works
against the spring pressure and evaporator suction pressure to
open the valve. If the load increases, the temperature
increases at the bulb, which increases the pressure on the top
side of the diaphragm. This opens the valve and increases the
flow of refrigerant. The increased refrigerant flow causes the
leaving evaporator temperature to decrease. This lowers the
pressure on the diaphragm and closes the pin. The refrigerant
flow is effectively stabilized to the load demand with
negligible change in superheat.
Replacing TXV
1. Recover refrigerant.
2. Remove TXV support clamp using a 5/l6-in. nut driver.
3. Remove TXV using a wrench and an additional wrench on
connections to prevent damage to tubing.
4. Remove equalizer tube from suction line of coil. Use file
or tubing cutter to cut brazed equalizer line approximately
2 inches above suction tube.
5. Remove bulb from vapor tube inside cabinet.
6. Install the new TXV using a wrench and an additional
wrench on connections to prevent damage to tubing while
attaching TXV to distributor.
7. Attach the equalizer tube to the suction line. If the coil has
a mechanical connection, then use a wrench and an addi-
tional wrench on connections to prevent damage. If the
coil has a brazed connection, use a file or a tubing cutter to
remove the mechanical flare nut from the equalizer line.
Then use a new coupling to braze the equalizer line to the
stub (previous equalizer line) in suction line.
8. Attach TXV bulb in the same location where the original
(in the sensing bulb indent) was when it was removed,
using the supplied bulb clamps. See Fig. 22.
9. Route equalizer tube through suction connection opening
(large hole) in fitting panel and install fitting panel in place.
10. Sweat the inlet of TXV marked “IN” to the liquid line. Avoid
excessive heat which could damage the TXV valve. Use
quenching cloth when applying heat anywhere on TXV.
Refrigerant System Pressure Access Ports
There are two access ports in the system: on the suction tube near
the compressor and on the discharge tube near the compressor.
These are brass fittings with black plastic caps. The hose connec-
tion fittings are standard 1/4-in. SAE male flare couplings.
The brass fittings are two-piece high flow valves, with a receptacle
base brazed to the tubing and an integral spring-closed check
valve core screwed into the base. See Fig. 23. This check valve is
permanently assembled into this core body and cannot be serviced
separately; replace the entire core body if necessary. Service tools
are available from RCD that allow the replacement of the check
valve core without having to recover the entire system refrigerant
charge. Apply compressor refrigerant oil to the check valve core’s
bottom o-ring. Install the fitting body with 96 ± 10 in.-lb
(10.85 ± 1.1 Nm) of torque; do not over-tighten.

PURON (R-410A) REFRIGERANT
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 cyl-
inders. 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 po-
sition (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 rec-
ommended that refrigerant always be removed from the cylinder
as a liquid. Admit liquid refrigerant into the system in the dis-
charge line. If adding refrigerant into the suction line, use a com-
mercial 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.
Refrigerant Charge
Amount of refrigerant charge is listed on the unit’s nameplate. Re-
fer to Bryant GTAC2-5 Charging, Recovery, Recycling and Recla-
mation training manual and the following procedures.
Unit panels must be in place when unit is operating during the
charging procedure.
NO CHARGE
Use standard evacuating techniques. After evacuating system,
weigh in the specified amount of refrigerant.
LOW-CHARGE COOLING
Using Cooling Charging Charts, Fig. 24-33, vary refrigerant until
the conditions of the appropriate chart are met. Note the charging
charts are different from type normally used. Charts are based on
charging the units to the correct sub-cooling for the various operat-
ing conditions. Accurate pressure gauge and temperature sensing
device are required. Connect the pressure gauge to the service port
on the liquid line. Mount the temperature sensing device on the
liquid line and insulate it so that outdoor ambient temperature does
not affect the reading. Indoor-air cfm must be within the normal
operating range of the unit.

USING COOLING CHARGING CHARTS
Take the outdoor ambient temperature and read the liquid pressure
gauge. Refer to chart to determine what liquid temperature should
be. If liquid temperature is low, add refrigerant. If liquid tempera-
ture is high, carefully recover some of the charge. Recheck the liq-
uid pressure as charge is adjusted.
