General InstructIOns

ImPOrtant

The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians. All duct work, supply and return

ducts, must be properly sized for the design airow

requirement of the equipment. 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.

shIPPInG DamaGe

Upon receipt of equipment, the carton should be
checked for external signs of shipping damage. If
damage is found, the receiving party must contact
the last carrier immediately, preferably in writing,
requesting inspection by the carrier’s agent.

General

The refrigerant system is completely assembled and
charged. All internal wiring is complete.

The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.

These instructions explain the recommended method
to install the air cooled self-contained unit and the
electrical wiring connections to the unit.

These instructions and any instructions packaged with
any separate equipment required to make up the entire
system should be carefully read before beginning the
installation. Note particularly “Starting Procedure” and
any tags and/or labels attached to the equipment.

While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation
is made.

FIelD InstalleD heater PacKaGes
(OPtIOnal)

These packaged air conditioners are manufactured
without supplementary electric heaters. Supplementary

heaters are available for simple, fast eld installation.

A separate power circuit is required for the
supplementary heaters.

IMPORTANT: Refer to Table 1 when designing duct
work for maximum available static pressure with heater
installed.

Refer to data shown in Table 3 and 4 for proper
application information on all available heater
combinations and what units they can be used with. It
also shows the applicable circuit ampacities, fuse size,
and wire size for each heater combination.

InstallatIOn

lOcatIOn

General

The unit must be located outside, or in a well ventilated
area. It must not be in the space being heated or cooled.
A sound absorbing material should be considered if the
unit is to be installed in such a position or location that
might cause transmission of sound or vibration to the
living area or adjacent buildings.

slab mOuntInG

A minimum of 24 inches should be provided between
the coil inlet and any building surfaces. Provide a
minimum of three feet clearance on the service access
side of the unit. See Figure 2.

tYPIcal InstallatIOns

1. rOOF mOunteD – The unit is mounted on a

sturdy base on the roof of the building. Return
air to the unit is brought through a single return

grille (grilles with built-in lters are best since they
enable easy access for lter changing). Return air

ducts are attached to the lower section of the front
panel. Supply air is brought from the unit to attic
duct work or to a furred down hall. Supply air duct
is attached to the top of the front panel.

In roof top installation, as in all installations, the

air conditioner must be level from side to side.
However, the unit should have a pitch along the
length to assure complete external drainage of
precipitation and of defrost condensate.

2.

craWl sPace – Duct work installed in crawl

space must be well insulated and provided with a
vapor barrier. In addition, the crawl space must
be thoroughly ventilated and provided with a good
vapor barrier as a ground cover. It is most desirable
to install the unit will be outdoors rather than inside
the crawl space, so that it will be readily accessible
for service.

3. slab mOunteD at GrOunD leVel – This

type installation is ideal for homes with a slab

oor construction where a roof mounted unit is not

desired. The supply and return duct work can be
run through a furred closet space.

4. thrOuGh the Wall – This type installation

requires a suitable framework to be fabricated
capable of withstanding the unit weight. Normally
the unit will be insulated so as to minimize supply
and return duct work.

CAUTION: All outdoor duct work must be

thoroughly insulated and weatherproofed. All
attic duct work must be thoroughly insulated.
Two inch thick insulation with suitable vapor
barrier is recommended for both outdoor and
attic runs.

5. Other InstallatIOns – Many other

installations are possible with the packaged air
conditioner. No matter what the installation, always
consider the following facts:

A. Insure that the discharge air is not obstructed in

any way so as to cause operation difculties.

B. The indoor coil drain pan is equipped with a

coupling that must be piped through a
condensate drain trap to a suitable drain.

C. Always mount the unit is such a position that it

may be easily reached for servicing and
maintenance.

D. Insure that the unit is clear so that proper air

ow over the outdoor coil will be maintained.

If this unit is operated in cooling below a 55° outdoor
ambient temperature, the installation of low ambient
controls (CMA-28) to unit is required.

Prior thought should be given to return air location and

placement of the air lter(s). The air lter(s) must be

of adequate size and readily accessible to the operator
of the equipment. Filters must be adequate in size and
properly maintained for proper operation. If this is
not done, excessive energy use, poor performance, and
multiple service problems will result. It is impossible
to oversize air lters. Generous sizing will result in
cleaner air and coils as well as lower operating costs
and extend the time between required changes. Table

5 shows minimum lter areas and recommended lter
sizes. Actual lter sizes can vary with the installation
due to single or multiple returns utilizing a lter/grille

arrangement or being placed immediately ahead of the
indoor coil face in the return air duct.

table 5

FIlter requIrements & sIzes

cOnDensate DraIn traP

It is very important to provide a trap in the condensate
drain line to allow a positive liquid seal in the line and
assure correct drainage from the coil condensate pan.

Install condensate drain trap shown in Figure 8. Use
drain connection size or larger. Do not operate unit
without trap. Unit must be level or slightly inclined
toward drain. With a trap installed on a unit located in
an unconditioned area, water in the trap may freeze. It
is recommended that the trap material be of a type that
will allow for expansion of water when it freezes.

aIr FIlters

Air lters for the return air side of the system are not
provided as part of these models, and must be eld
supplied and installed as part of the nal installation.

WIrInG – maIn POWer

Refer to the unit rating plate for wire sizing information
and maximum fuse 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. If eld installed heaters are added to the

basic unit, a second separate power supply circuit will
be required. The heater rating plate located adjacent
to the basic unit rating plate will show the appropriate
circuit ampacity fuse size, etc. (Also see “Electrical

Specications” on pages 5 & 7.) All models are
suitable for connection with copper wire only. These

instructions must be adhered to. Refer to the National
Electrical Code for complete current carrying capacity
data on the various insulation grades of wiring material.

The electrical specications list fuse and wire sizes

(75°F copper) for all models including the most
commonly used heater sizes.

The unit rating plate lists a “Maximum Time Delay
Fuse” or “HACR” type 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.

Five (5) wires should be run from thermostat subbase

to the 24V terminal board in the unit. A ve conductor,

18 gauge copper, color-coded thermostat cable is
recommended. The connection points are shown in

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. 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 insure 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 ultimate 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.

For improved start up performance, wash the indoor

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
LED’s. 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 tow of the supply
leads to the unit. Do not reverse any of the unit factory
wires as damage may occur.

sequence OF OPeratIOn

blOWer OnlY – When the “Fan” switch on the

room thermostat is placed in the “On” position (circuit
R-G makes), the blower will energize and run until the
“Fan” switch is placed back into the “Auto” position.
This will allow for constant air circulation at a lower

airow during times when the unit is not in operation

for cooling or heating.

cOOlInG – On a call for cooling from the room

thermostat (circuit R-Y makes), the blower will
energize (circuit R-G is automatic when R-Y makes) as
well as the compressor, and outdoor fan motor. Note
that if the “Fan” switch on the room thermostat is in the
“On” position and the blower is already in operation,
then the motor will ramp up to the required speed for
cooling.

heatInG (1st stage) – On a call for heating

from the room thermostat (circuit R-W1 makes), the
blower will energize (circuit R-G is automatic when
R-W1 makes). This will place the system into heating
operation to maintain the thermostat set temperature.
Note that if the “Fan” switch on the room thermostat
is in the “On” position and the blower is already in
operation, then the motor will ramp up to the required
speed for heating.

InDOOr blOWer mOtOr

These models feature a variable speed (ECM) motor

providing high efciency, low sound levels and soft

start capabilities. The motor is self adjusting to provide

the proper airow rate at duct static pressures up to

0.50" WC without user adjustment or wiring changes.
On command from the wall thermostat the motor will

start slowly and ramp up to full speed over a period of
10-15 seconds.

When the thermostat is satised the blower will operate

for approximately 1 minute, and then slow down and
stop.

The compressor control is an anti-short cycle/lockout
timer with high and low pressure switch monitoring and
alarm output.

aDJustable DelaY-On-maKe anD breaK
tImer

On a call for compressor operation the delay-on-make
period begins which will be 10% of the delay-on-
break setting. When the delay-on-make is complete
and the high pressure switch (and low pressure switch
if employed) is closed, the compressor contactor is
energized. Upon shutdown, the delay-on-break timer
starts and prevents restart until the delay-on-break and
delay-on-make periods have expired.

hIGh Pressure sWItch anD lOcKOut
sequence (standard Feature)

If the high pressure switch opens, the compressor
contactor will de-energize immediately. The lockout
timer will go into a soft lockout and stay in soft lockout
until the high pressure switch closes and the delay­on-make time has expired. If the high pressure switch
opens again in this same operating cycle the unit will
go into manual lockout condition and the alarm circuit
will energize. Recycling the wall thermostat resets the
manual lockout.

heatInG (2nd stage) – If the operation of the 1st

Stage electric heaters will not maintain the set room
temperature, then the thermostat will call for additional
heat to help maintain the set temperature. On a call
for second stage heating from the room thermostat
(circuit R-W2 makes), additional electric heaters will
be energized if installed.

If the low pressure switch opens for more that 120
seconds, the compressor contactor will de-energize
and go into a soft lockout. Regardless the state of the
low pressure switch, the contactor will reenergize after
the delay-on-make time delay has expired. If the low
pressure switch remains open or opens again for longer
than 120 seconds the unit will go into manual lockout
condition and the alarm circuit will energize. Recycling
the wall thermostat resets the manual lockout.

alarm OutPut

Alarm terminal is output connection for applications
where alarm signal is desired. This terminal is powered
whenever compressor is locked out due to HPC or LPC
sequences as described.

NOTE: Both high and low pressure switch controls

are inherently automatic reset devices. The
high pressure switch and low pressure switch

cut out and cut in settings are xed by specic

air conditioner or heat pump unit model. The
lockout features, both soft and manual, are a
function of the Compressor Control Module.

aDJustments

Optional Low Ambient Control

An optional low ambient control is available for both

factory and eld installed options. The low ambient

control is to be applied to the PA13 Series models when
operation below 55° outdoor conditions are anticipated.
Without this device, the evaporating pressure would fall
off, and the indoor coil would ice over.

The fan cycling control cycles the fan motor on, once
the liquid refrigerant pressure reaches 350 psig, and
off, once it has dropped to 225 psig. It will continue to
cycle between these parameters depending on outdoor
temperatures and the load/stage of the system.

This cycling maintains a minimum liquid pressure
affecting the minimum suction pressure. This effect
insures an evaporating temperature that is slightly above
the point of ice formation on the evaporator.

This eld installed option is Bard Part #CMA-28. See

Figure 7.

1. Caution homeowner to maintain clean air lters at

all times. Also, not to 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
that they are the correct rating.

3. Periodic cleaning of the outdoor coil to permit full

and unrestricted airow circulation is essential.

This unit was charged at the factory with the quantity
of refrigerant listed on the serial plate. AHRI capacity

and efciency ratings were determined by testing with

this refrigerant charge quantity.
The following pressure tables show nominal

pressures for the units. Since many installation

specic situations can affect the pressure readings,
this information should only be used by certied

technicians as a guide for evaluating proper system
performance. They shall not be used to adjust charge.
If charge is in doubt, reclaim, evacuate and recharge

suctIOn anD DIscharGe tube

Compliant Scroll compressors have copper plated
steel suction and discharge tubes. These tubes are far
more rugged and less prone to leaks than copper tubes
used on other compressors. Due to different thermal
properties of steel and copper, brazing procedures may
have to be changed from those commonly used.

• To disconnect: heat joint Areas 2 and 3 slowly and

uniformly until braze material softens and the tube

can be pulled out of suction tting. (See Figure 9.)

• To connect:

– Recommended brazing materials: silfos with

minimum 5% silver or silver braze material with

ux.

brazInG DIaGram

– Reinsert tube into tting.

– Heat tube uniformly in Area 1 moving sl owly to

Area 2. When joint reaches brazing
temperature, apply brazing material. (See
Figure 9)

– Heat joint uniformly around the circumference

to ow braze material completely around the

joint.

– Slowly move torch into Area 3 to draw braze

material into joint. (See Figure 9.)

– Do not overheat joint.

TROUBLESHOOTING GE X13-SERIES ECM2.3™ MOTORS

If the Motor is Running

1. It is normal for the motor to rock back and forth on start up.

Do not replace the motor if this is the only problem identified.

2. If the system is excessively noisy, does not appear to change
speeds in response to a demand (Heat, Cool, Other), or is having
symptoms during the cycle such as tripping limit or freezing coil,
check the following:

a. Wait for programmed delays to time out.
b.Ensure that the motors control inputs are wired to the factory

supplied wiring diagram to insure motor is getting proper
control signals and sequencing.

c. Remove the filter and check that all dampers, registers, and

grilles are open and free flowing. If removing the filters
corrects the problem, clean or replace with a less restrictive
filter. Also check and clean the blower wheel or coil as
necessary.

d.Check the external static pressure (total of both supply and

return) to insure that you are within the ranges as listed on the
unit serial plate. If higher than allowed, additional duct work
is needed.

e. If the motor does not shut off at the end of the cycle, wait for

any programmed delays to time out (no more than 90
seconds). Also make sure that there is no call for
“Continuous Fan” on the "G" terminal.

f. If the above diagnostics do not solve the problem, confirm the

voltage checks in the next section below, then continue with
the “Model X13 Communication Diagnostics”.

If the Motor is Not Running

1. Check for proper high voltage and ground at the (L/L1) (G) (N/
L2) connections at the motor (see Figure 10). Correct any voltage
issues before proceeding to the next step. The X13 Motor is voltage
specific. Only the correct voltage should be applied to the proper
motor. Input voltage within plus or minus 10% of the nominal 230
VAC is acceptable.

2. If the motor has proper high voltage and ground at the (L/L1)
(G) (N/L2) connections, then continue with the “Model X13
Communication Diagnostics”.

2. Initiate a demand from the thermostat and check the
voltage between the common and the appropriate motor
terminal (1-5). ("G" input is typically on terminal #1, but
refer to wiring diagram!)

a. If the low voltage communication is not present, check

the demand from the thermostat. Also check the
output terminal and wire(s) from the terminal strip or
control relay(s) to the motor.

b. If the motor has proper high voltage as identified

above (Motor not Running #1), and proper low voltage
to a programmed terminal, and is not operating, the
motor is failed, and will require replacement.

Model X13 Communication Diagnostics

The X13 motor is communicated through 24 VAC low voltage
(Thermostat Control Circuit Wiring).

1. Start with unit wiring diagram to conrm proper
connections and voltage (see Figure 11).
