Conditioning Systems, NFPA No. 90B. Where local
regulations are at a variance with instructions, installer
should adhere to local codes.
Duct Work
All duct work, supply and return, must be properly
sized for the design airow requirement of the
equipment. Air Conditioning Contractors of America
(ACCA) is an excellent guide to proper sizing. All duct
work or portions thereof not in the conditioned space
should be properly insulated in order to both conserve
energy and prevent condensation or moisture damage.
Design the duct work according to methods given by
the Air Conditioning Contractors of America (ACCA).
When duct runs through unheated spaces, it should
be insulated with a minimum of 1" of insulation. Use
insulation with a vapor barrier on the outside of the
insulation. Flexible joints should be used to connect
the duct work to the equipment in order to keep the
noise transmission to a minimum.
A 1/4" clearance to combustible material for the rst
3' of duct attached to the outlet air frame is required.
See Mounting the Unit (page 6) and Figures 3 and
4 (beginning on page 8) for further details.
Ducts through the walls must be insulated and all
joints taped or sealed to prevent air or moisture
entering the wall cavity.
Some installations may not require any return air duct.
A metallic return air grille is required with installations
not requiring a return air duct. The spacing between
louvers on the grille shall not be larger than 5/8".
Any grille that meets with 5/8" louver criteria may
be used. It is recommended that Bard Return Air
Grille kits RG2 through RG5 or RFG2 through RFG5
be installed when no return duct is used. Contact
distributor or factory for ordering information. If using a
return air lter grille, lters must be of sufcient size to
allow a maximum velocity of 400 fpm.
NOTE: If no return air duct is used, applicable
installation codes may limit this cabinet to
installation only in a single story structure.
Filters
A 1" throwaway lter is standard with each unit. The
lter slides into position making it easy to service. This
lter can be serviced from the outside by removing the
lter access panel. 2" pleated lters are also available
as optional accessories. The internal lter brackets are
adjustable to accommodate the 2" lter by bending
two (2) tabs down on each side of the lter support
bracket.
Fresh Air Intake
All units are built with fresh air inlet slots punched in
the service door.
If the unit is equipped with a fresh air damper
assembly, the assembly is shipped already attached
to the unit. The damper blade is locked in the closed
position. To allow the damper to operate, the maximum
and minimum blade position stops must be installed
(see Figure 1).
All capacity, efciency and cost of operation
information is based upon the fresh air blank-off plate
in place and is recommended for maximum energy
efciency.
The blank-off plate is available upon request from the
factory and is installed in place of the fresh air damper
shipped with each unit.
Condensate Drain
A plastic drain hose extends from the drain pan at
the top of the unit down to the unit base. There are
openings in the unit base for the drain hose to pass
through. In the event the drain hose is connected to
a drain system of some type, it must be an open or
vented type system to assure proper drainage.

INSTALLATION
Wall Mounting Information
1. Two holes for the supply and return air openings
must be cut through the wall as shown in Figure 3
on page 8.
2. On wood frame walls, the wall construction must
be strong and rigid enough to carry the weight of
the unit without transmitting any unit vibration.
3. Concrete block walls must be thoroughly inspected
to insure that they are capable of carrying the
weight of the installed unit.
Mounting the Unit
1. These units are secured by wall mounting brackets
which secure the unit to the outside wall surface at
both sides. A bottom mounting bracket, attached
to skid for shipping, is provided for ease of
installation, but is not required.
2. The unit itself is suitable for 0" clearance, but the
supply air duct ange and the rst 3' of supply
air duct require a minimum of 1/4" clearance to
combustible material. However, it is generally
recommended that a 1" clearance is used for
ease of installation and maintaining the required
clearance to combustible material. See Figure 3
(page 8) for details on opening sizes.
3. Locate and mark lag bolt locations and bottom
mounting bracket location. See Figure 3.
4. Mount bottom mounting bracket.
5. Hook top rain ashing, attached to front-right of
supply ange for shipping, under back bend of top.
6. Position unit in opening and secure with 5/16" lag
bolts; use 7/8" diameter at washers on the lag bolts.
7. Secure rain ashing to wall and caulk across entire
length of top. See Figure 3.
8. For additional mounting rigidity, the return air
and supply air frames or collars can be drilled
and screwed or welded to the structural wall itself
(depending upon wall construction). Be sure to
observe required clearance if combustible wall.
Placement
1. On side-by-side installations, maintain a minimum
of 20" clearance on right side to allow access to
control panel and heat strips, and to allow proper
airow to the outdoor coil. Additional clearance
may be required to meet local or national codes.
2. Care should be taken to ensure that the
recirculation and obstruction of condenser
discharge air does not occur. Recirculation of
condenser discharge air can be from either a
single unit or multiple units. Any object such
as shrubbery, a building or a large object can
cause obstructions to the condenser discharge
air. Recirculation or reduced airow caused by
obstructions will result in reduced capacity,
possible unit pressure safety lockouts and reduced
unit service life.
For units with a blow-through condenser, such as
the T**S 11EER units, it is recommended there
be a minimum distance of 15' between the front of
the unit and any barrier or 20' between the fronts
of two opposing (facing) units.
Required Steps after Final Placement
(T48S & T60S Units Only)
The compressor is secured to the unit base for
shipping. Although unit will perform as designed
with the compressor secured in place, there may be
noticeable additional noise and vibration. To obtain
the lowest noise and vibration levels, remove the
WARNING
Failure to provide the 1/4" clearance between
the supply duct and a combustible surface
for the rst 3ʹ of duct can result in re causing
damage, injury or death.
WARNING
Failure to bolt the unit to the wall could result
in the unit falling, causing injury or death!
Follow all mounting instructions.

Wiring – Main Power
Refer to the unit rating plate for wire sizing information
and maximum fuse or circuit breaker size. Each
outdoor unit is marked with a “Minimum Circuit
Ampacity”. This means that the eld wiring used must
be sized to carry that amount of current. Depending
on the installed KW of electric heat, there may be two
eld power circuits required. If this is the case, the
unit serial plate will so indicate. All models are suitable
only for connection with copper wire. Each unit and/or
wiring diagram will be marked “Use Copper Conductors
Only”. These instructions must be adhered to. Refer
to the National Electrical Code (NEC) for complete
current carrying capacity data on the various insulation
grades of wiring material. All wiring must conform to
NEC and all local codes.
The electrical data lists fuse and wire sizes (75°C
copper) for all models including the most commonly
used heater sizes. Also shown are the number of eld
power circuits required for the various models with
heaters.
The unit rating plate lists a maximum time delay relay
fuse or circuit breaker that is to be used with the
equipment. The correct size must be used for proper
circuit protection and also to assure that there will
be no nuisance tripping due to the momentary high
starting current of the compressor motor.
The disconnect access door on this unit may be locked
to prevent unauthorized access to the disconnect. To
convert for the locking capability, bend the tab located
in the bottom left-hand corner of the disconnect
opening under the disconnect access panel straight
out. This tab will now line up with the slot in the door.
When shut, a padlock may be placed through the hole
in the tab preventing entry.
See Three Phase Scroll Compressor Start Up
Information on page 14 for important information on
three phase scroll compressor start ups.
See Tables 6A and 6B (pages 21 and 22) for electrical
specications.
Wiring – Low Voltage
All 230/208V 1 phase and 3 phase equipment have
dual primary voltage transformers. All equipment leaves
the factory wired on 240V tap. For 208V operation,
reconnect from 240V to 208V tap. The acceptable
operating voltage range for the 240 and 208V taps are:
TAP RANGE
240 253 – 216
208 220 – 187
NOTE: The voltage should be measured at the field
power connection point in the unit and while
the unit is operating at full load (maximum
amperage operating condition).
For wiring size and connections, refer to Wiring Manual
2100-554.
Optional Outdoor Thermostat
Applications
Since most equipment at the time of manufacture
is not designated for any specic destination of the
country and are installed in areas not approaching the
lower outdoor temperature range, outdoor thermostats
are not factory installed as standard equipment, but
are offered as an option. There are also different
applications for applying outdoor thermostats.
The setpoint of either type of outdoor thermostat
application is variable with geographic region and
sizing of the heating equipment to the individual
structure. Utilization of the heating Application Data,
and the heat loss calculation of the building are useful
in determining the correct set points.
NOTE: The additional LAB (low ambient bypass) relay
is required to prevent heater operation during
low temperature cooling operation.

START UP
These units require R-410A refrigerant and Polyol Ester
oil.
General
1. Use separate service equipment to avoid cross
contamination of oil and refrigerants.
2. Use recovery equipment rated for R-410A
refrigerant.
3. Use manifold gauges rated for R-410A (800
psi/250 psi low).
4. R-410A is a binary blend of HFC-32 and HFC-
125.
5. R-410A is nearly azeotropic—similar to R-22 and
R-12. Although nearly azeotropic, charge with
liquid refrigerant.
6. R-410A operates at 40-70% higher pressure
than R-22 and systems designed for R-22 cannot
withstand this higher pressure.
7. R-410A has an ozone depletion potential of zero,
but must be reclaimed due to its global warming
potential.
8. R-410A compressors use Polyol Ester oil.
9. Polyol Ester oil is hygroscopic; it will rapidly absorb
moisture and strongly hold this moisture in the oil.
10. A liquid line dryer must be used—even a deep
vacuum will not separate moisture from the oil.
11. Limit atmospheric exposure to 15 minutes.
12. If compressor removal is necessary, always plug
compressor immediately after removal. Purge with
small amount of nitrogen when inserting plugs.
Topping Off System Charge
If a leak has occurred in the system, Bard
Manufacturing recommends reclaiming, evacuating
(see criteria above) and charging to the nameplate
charge. If done correctly, topping off the system charge
can be done without problems.
With R-410A, there are no signicant changes in the
refrigerant composition during multiple leaks and
recharges. R-410A refrigerant is close to being an
azeotropic blend (it behaves like a pure compound
or single component refrigerant). The remaining
refrigerant charge, in the system, may be used after
leaks have occurred and then “top-off” the charge by
utilizing the pressure charts on the inner control panel
cover as a guideline.
REMEMBER: When adding R-410A refrigerant, it must
come out of the charging cylinder/tank as a liquid to
avoid any fractionation, and to ensure optimal system
performance. Refer to instructions for the cylinder that
is being utilized for proper method of liquid extraction.
Safety Practices
1. Never mix R-410A with other refrigerants.
2. Use gloves and safety glasses. Polyol Ester oils can
be irritating to the skin and liquid refrigerant will
freeze the skin.
3. Never use air and R-410A to leak check; the
mixture may become ammable.
4. Do not inhale R-410A—the vapor attacks
the nervous system, creating dizziness, loss
of coordination and slurred speech. Cardiac
irregularities, unconsciousness and ultimately
death can result from breathing this concentration.
5. Do not burn R-410A. This decomposition produces
hazardous vapors. Evacuate the area if exposed.
6. Use only cylinders rated DOT4BA/4BW 400.
7. Never ll cylinders over 80% of total capacity.
8. Store cylinders in a cool area, out of direct
sunlight.
9. Never heat cylinders above 125°F.
10. Never trap liquid R-410A in manifold sets, gauge
lines or cylinders. R-410A expands signicantly at
warmer temperatures. Once a cylinder or line is full
of liquid, any further rise in temperature will cause
it to burst.
WARNING
Failure to conform to these practices could
lead to damage, injury or death.

Important Installer Note
For improved start up performance, wash the indoor
coil with a dish washing detergent.
High and Low Pressure Switch
All T**S wall-mounted air conditioner series models
are supplied with a remote reset for the high and low
pressure switch. If tripped, this pressure switch may be
reset by turning the thermostat off then back on again.
Three Phase Scroll Compressor Start
Up Information
Scroll compressors, like several other types of
compressors, will only compress in one rotational
direction. Direction of rotation is not an issue with
single phase compressors since they will always start
and run in the proper direction.
However, three phase compressors will rotate in either
direction depending upon phasing of the power.
Since there is a 50-50 chance of connecting power
in such a way as to cause rotation in the reverse
direction, verication of proper rotation must be made.
Verication of proper rotation direction is made by
observing that suction pressure drops and discharge
pressure rises when the compressor is energized.
Reverse rotation also results in an elevated sound level
over that with correct rotation, as well as substantially
reduced current draw compared to tabulated values.
Verication of proper rotation must be made at the
time the equipment is put into service. If improper
rotation is corrected at this time, there will be no
negative impact on the durability of the compressor.
However, reverse operation for over 1 hour may have a
negative impact on the bearing due to oil pump out.
NOTE: If compressor is allowed to run in reverse
rotation for several minutes, the compressor’s
internal protector will trip.
All three phase ZP compressors are wired identically
internally. As a result, once the correct phasing is
determined for a specic system or installation,
connecting properly phased power leads to the same
Fusite terminal should maintain proper rotation
direction.
The direction of rotation of the compressor may be
changed by reversing any two line connections to the
unit.
Phase Monitor
All units with three phase scroll compressors are
equipped with a three phase line monitor to prevent
compressor damage due to phase reversal.
The phase monitor in this unit is equipped with two
LEDs. If the Y signal is present at the phase monitor
and phases are correct, the green LED will light. If
phases are reversed, the red fault LED will be lit and
compressor operation is inhibited.
If a fault condition occurs, reverse two of the supply
leads to the unit. Do not reverse any of the unit factory
wires as damage may occur.
Service Hints
1. Caution owner/operator to maintain clean air
lters at all times and to not needlessly close off
supply and return air registers. This reduces airow
through the system, which shortens equipment
service life as well as increasing operating costs.
2. Check all power fuses or circuit breakers to be sure
they are the correct rating.
3. Periodic cleaning of the outdoor coil to permit full
and unrestricted airow circulation is essential.
CAUTION
Remove service panels carefully. Falling
panels could cause lacerations.

Sequence of Operation
Cooling Stage 1
Circuit R-Y makes at thermostat pulling in compressor
contactor, starting the compressor and outdoor motor.
The G (indoor motor) circuit is automatically completed
on any call for cooling operation or can be energized
by manual fan switch on subbase for constant air
circulation.
Cooling Stage 2
Circuit R-Y1 makes at the thermostat energizing the
2nd stage solenoid in the compressor. Default position
is not energized. Compressor will run at low capacity
until this solenoid is energized.
Heating Stage 1
A 24V solenoid coil on reversing valve controls heating
cycle operation. Two thermostat options, one allowing
“Auto” changeover from cycle to cycle and the other
constantly energizing solenoid coil during heating season
and thus eliminating pressure equalization noise except
during defrost, are to be used. On “Auto” option a
circuit is completed from R-B and R-Y on each heating
“on” cycle, energizing reversing valve solenoid and
pulling in compressor contactor starting compressor and
outdoor motor. R-G also make starting indoor blower
motor. Heat pump heating cycle now in operation. The
second option has no “Auto” changeover position, but
instead energizes the reversing valve solenoid constantly
whenever the system switch on subbase is placed in
“Heat” position, the “B” terminal being constantly
energized from R. A thermostat demand for Stage 1 heat
completes R-Y circuit, pulling in compressor contactor
starting compressor and outdoor motor. R-G also make
starting indoor blower motor.
Heating Stage 2
Circuit R-Y2 makes at the thermostat energizing the
2nd stage solenoid in the compressor.
Pressure Service Ports
High and low pressure service ports are installed on
all units so that the system operating pressures can
be observed. Pressure Tables 5A and 5B covering all
models can be found on page 20. It is imperative to
match the correct pressure table to the unit by model
number.
This unit employs high-ow Coremax valves instead of
the typical Shrader type valves.
WARNING! Do NOT use a Schrader valve core removal
tool with these valves. Use of such a tool could result in
eye injuries or refrigerant burns!
To change a Coremax valve without rst removing the
refrigerant, a special tool is required which can be
obtained at www.fastestinc.com/en/SCCA07H. See the
replacement parts manual for replacement core part
numbers.
Defrost Cycle
The defrost cycle is controlled by temperature and time
on the solid state heat pump control.
When the outdoor temperature is in the lower
40°F temperature range or colder, the outdoor coil
temperature is 32°F or below. This coil temperature is
sensed by the coil temperature sensor mounted near
the bottom of the outdoor coil. Once coil temperature
reaches 30°F or below, the coil temperature sensor
sends a signal to the control logic of the heat pump
control and the defrost timer will start accumulating
run time.
After 30, 60 or 90 minutes of heat pump operation at
30°F or below, the heat pump control will place the
system in the defrost mode.
During the defrost mode, the refrigerant cycle switches
back to the cooling cycle, the outdoor motor stops,
electric heaters are energized and hot gas passing
through the outdoor coil melts any accumulated frost.
When the temperature rises to approximately 57°F, the
coil temperature sensor will send a signal to the heat
pump control which will return the system to heating
operations automatically.
If some abnormal or temporary condition such as a high
wind causes the heat pump to have a prolonged defrost
cycle, the heat pump control will restore the system to
heating operation automatically after 8 minutes.
The heat pump defrost control board has an option of
30-, 60- or 90-minute setting. By default, this unit
is shipped from the factory with the defrost time on
the 60 minute pin. If circumstances require a change
to another time, remove the wire from the 60 minute
terminal and reconnect to the desired terminal. Refer
to Figure 8.
There is a cycle speed up jumper on the control. This
can be used for testing purposes to reduce the time
between defrost cycle operation without waiting for
time to elapse.
Use a small screwdriver or other metallic object, or
another ¼" QC, to short between the SPEEDUP terminals
to accelerate the HPC timer and initiate defrost.
Be careful not to touch any other terminals with the
instrument used to short the SPEEDUP terminals.
It may take up to 10 seconds with the SPEEDUP
terminals shorted for the speedup to be completed and
the defrost cycle to start.
As soon as the defrost cycle kicks in, remove the
shorting instrument from the SPEEDUP terminals.
Otherwise the timing will remain accelerated and
run through the 1-minute minimum defrost length
sequence in a matter of seconds and will automatically
terminate the defrost sequence.

FIGURE 8
Defrost Control Board
There is an initiate defrost jumper (SEN JMP) on the
control that can be used at any outdoor ambient during
the heating cycle to simulate a 0° coil temperature.
This can be used to check defrost operation of the unit
without waiting for the outdoor ambient to fall into the
defrost region.
By placing a jumper across the SEN JMP terminals (a
¼" QC terminal works best), the defrost sensor mounted
on the outdoor coil is shunted out and will activate
the timing circuit. This permits the defrost cycle to be
checked out in warmer weather conditions without the
outdoor temperature having to fall into the defrost region.
In order to terminate the defrost test, the SEN JMP
jumper must be removed. If left in place too long, the
compressor could stop due to the high pressure control
opening because of high pressure condition created
by operating in the cooling mode with outdoor fan off.
Pressure will rise fairly fast as there is likely no actual
frost on the outdoor coil in this articial test condition.
There is also a 5-minute compressor time delay function
built into the HPC. This is to protect the compressor
from short cycling conditions. The board’s LED will have
a fast blink rate when in the compressor time delay. In
some instances, it is helpful to the service technician to
override or speed up this timing period, and shorting out
the SPEEDUP terminals for a few seconds can do this.
Low Pressure Switch Bypass Operation
The control has a selectable (SW1) low pressure switch
bypass set up to ignore the low pressure switch input during
the rst (30, 60, 120 or 180 seconds) of “Y” operation.
After this period expires, the control will then monitor the
low pressure switch input normally to make sure that the
switch is closed during “Y” operation.
High Pressure Switch Operation
The control has a built-in lockout system that allows
the unit to have the high pressure switch trip up to two
times in 1 hour and only encounter a “soft” lockout. A
“soft” lockout shuts the compressor off and waits for the
pressure switch to reset, which at that point then allows
the compressor to be restarted as long as the 5-minute
short cycle timer has run out. If the high pressure switch
trips a third time within 1 hour, the unit is in “hard”
lockout indicating something is certainly wrong and it
will not restart itself.

Yes = go to Step #2; No = go to Step #3
2. Check for error codes.
Is the LED ashing a code? Yes = go to Step #4; No = go to Step #8
3. Check for power at board.
Is there 24 volts AC between R and C? Yes = go to Step #13; No = go to Step #9
4. Check codes.
What code is blinking? Code "1", got to Step #6; Code "2", go to Step #7; Fast Blink, go to Step #5
5. Compressor delay active.
Wait for 5 minute delay or jump board's
"speed up pins".
Check for proper operation; if still needed, go back to Step #1
6. Low pressure fault. Check wiring circuit and unit pressures.
7. High pressure fault. Check wiring circuit and unit pressures.
8. Check for Compressor input signal.
Is there 24 volts AC between Y and C? Yes = go to Step #10; No = go to Step #11
9. No power to board. The unit either does not have unit voltage, the transformer is bad or the unit wiring
is incorrect.
10. Check for Compressor output signal.
Is there 24 volts AC between CC and C? Yes = go to Step #12; No = go to Step #13
11. No "Y" compressor input signal. Check thermostat wiring, incorrect phase of unit (see section on Phase Monitor)
and nally unit wiring.
12. No "CC" compressor output signal. Check compressor contactor for proper operation and nally check compressor.
13. Faulty board. Replace defrost board.

Solid State Heat Pump Control
Troubleshooting Procedure
1. NOTE: A thorough understanding of the defrost
cycle sequence is essential. Review that section
(page 16) prior to troubleshooting the control. Turn
on AC power supply to unit.
2. Turn thermostat blower switch to “fan on”—
the indoor blower should start. (If it doesn’t,
troubleshoot indoor unit and correct problem.)
3. Turn thermostat blower to “auto” position. Indoor
blower should stop. NOTE: Many models have a
1-minute blower time delay on “off” command;
wait for this to time out.
4. Set system switch to “heat” or “cool”. Adjust
thermostat to call for heat or cool. The indoor
blower, compressor and outdoor fan should start.
NOTE: If there was no power to 24 volt transformer,
the compressor and outdoor fan motor will
not start for 5 minutes. This is because of the
compressor short cycle protection.

2. Use an ohmmeter and measure the resistance of
the sensor. Also use ohmmeter to check for short
or open.
3. Check resistance reading to chart of resistance.
Use sensor ambient temperature. (Tolerance of part
is ± 10%.)
4. If sensor resistance reads very low, then sensor is
shorted and will not allow proper operation of the
heat pump control.
5. If sensor is out of tolerance, shorted, open or reads
very low ohms, then it should be replaced.
