Ventilation System Packages
Bard Wall-Mounts are designed to provide optional ventilation packages to meet all of your ventilation and indoor air quality requirements. All
units are equipped with a barometric fresh air damper as the standard ventilation package. All ventilation packages can be built-in at the
factory or field-installed at a later date.
BAROMETRIC FRESH AIR DAMPER - BFAD
STANDARD
The barometric fresh air damper is a standard feature on all models. It is installed on the inside of the service
door and allows outside ventilation air, up to 25% of the total airflow rating of the unit, to be introduced through the
air inlet openings and to be mixed with the conditioned air. The damper opens during blower operation and
closes when the blower is off. Adjustable blade stops allow different amounts of outside air to be introduced into
the building and can be easily locked closed if required.
Barometric Fresh Air Damper
BLANK OFF PLATE - BOP
OPTIONAL
A blank off plate is installed on the inside of the service door. It covers the air inlet openings, which restricts any
outside air from entering the unit. The blank off plate should be utilized in applications where outside air is not
required to be mixed with the conditioned air.
MOTORIZED FRESH AIR DAMPER - MFAD
OPTIONAL
The motorized fresh air damper is internally mounted behind the service door and allows outside ventilation air,
up to 25% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be mixed
with the conditioned air. The two position damper can be fully open or closed. The damper blade is powered
open by a 24VAC motor with spring return on power loss. The damper can be controlled by indoor blower
operation or can be field connected to be managed based on building occupancy.
Motorized Fresh Air Damper
NOTE: The above vent systems are intake only without built-in exhaust capability. Building will likely require
separate field installed barometric relief or mechanical exhaust elsewhere within the conditioned space. Balancing
dampers in the return air grille may be required to achieve specified amount of outdoor air intake.
COMMERCIAL ROOM VENTILATOR - CRV
OPTIONAL
The built-in commercial room ventilator is internally mounted behind the service door and allows outside
ventilation air, up to 50% of the total airflow rating of the unit, to be introduced through the air inlet openings.
It includes a built-in exhaust air damper.
Commercial Room Ventilator
The commercial room ventilator (CRV) is a simple and innovative approach to improving the indoor air quality by
providing fresh air intake and exhaust capability through the CRV. The damper can be easily adjusted to control the
amount of fresh air supplied into the building. The CRV can be controlled by indoor blower operation or field controlled
based on room occupancy. Two versions available (except on 1.5 and 2-Ton models). The CRV and CRVS are
power open - spring return on power loss, and CRVP is power open and power close. Complies with ANSI/ASHRAE
Standard 62.1 “Ventilation for Acceptable Indoor Air Quality”.
ECONOMIZER - EIFM
OPTIONAL
The built-in economizer system is internally mounted behind the service door and allows outdoor air to be
introduced through the air inlet openings. The amount of outdoor air varies in response to the system controls and
settings defined by the end user. It includes a built-in exhaust air damper. The economizer is designed to provide
“free cooling” when outside air conditions are cool and dry enough to satisfy cooling requirements without running
the compressor. This in turn provides lower operating costs, while extending the life of the compressor.
Economizer
Standard Features:
• One Piece Construction - Easy to install with no mechanical linkage adjustment required.
• Exhaust Air Damper - Built in with positive closed position. Provides exhaust air capability to prevent
pressurization of tight buildings.
•
•
•
•
•
Actuator Motor - 24 volt, power open, spring return with built in torque limiting switch.
Proportioning Type Control - for maximum “free cooling” economy and comfort.
Moisture Eliminator & Prefilter - permanent, washable aluminum construction.
Enthalpy Control - adjustable to monitor outdoor temperature and humidity.
Minimum Position Potentiometer - adjustable to control minimum damper blade position for ventilation
purposes.
• Mixed Air Sensor - to monitor outside and return air to automatically modulate damper position.
WALL-MOUNT ENERGY RECOVERY VENTILATOR - WERV
Energy Recovery Ventilator
OPTIONAL
The wall-mount energy recovery ventilator (WERV) is a highly innovative approach to meeting indoor air quality
ventilation requirements as established by ANSI/ASHRAE Standard 62.1. The WERV allows from 200 to 450
CFM (depending upon model) of fresh air and exhaust through the unit while maintaining superior indoor comfort
and humidity levels. In most cases this can be accomplished without increasing equipment sizing or operating
costs. Heat transfer efficiency is up to 67% during summer and 75% during winter conditions.
The WERV consists of a unique “rotary energy recovery cassette” that provides effective sensible and latent heat
transfer capabilities during summer and winter conditions. Various control schemes are addressed including
limiting ventilation during building occupancy only.
The WERV is designed to be internally mounted behind the service door in the WA, WH or WL model wall-mount
units. It can be built-in at the factory or field installed as an option. WERV-*3C and WERV-*5C can be
independently adjusted for intake and exhaust rates.

1 Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
2 Based on 75C copper wire. All wiring must conform to the National Electrical Code and all local codes.
3 These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article 310 for
power conductor sizing.
Caution: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to note 8 of Table 310
regarding Ampacity Adjustment Factors when more than three (3) current carrying conductors are in a raceway.
* Top outlet supply option is available only factory installed and only on the selected models.
IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor wires in accordance with the
National Electrical Code and all local codes.

CMA-24 STD = Standard equipment for these specified models.
1 TDR. Time delay relay only for compressor is fixed 5-minute delay-on-break to prevent short cycling. Not needed if HPC or LPC are used. See notes 2, 3 and 4.
2 HPC. High pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note 4.
3 LPC. Low pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note 4.
4 CCM. Compressor control module has adjustable 30-second to 5-minute delay-on-break timer. On initial power-up, or any time the power is interrupted, the delay-on-make will be 2minutes plus 10% of the delay-on-break setting. There is no delay-on-make during routine operation of the unit. The module also provides the lockout feature (with 1 retry) for
high and/or low-pressure controls, and a 2-minute timed bypass for low-pressure control.
5 LAC. Low ambient control permits cooling operation down to 0°F
6 ALR. The alarm relay has a set of normally open and normally closed dry contacts to provide the ability to signal a condition of shutdown on either high or low pressure controls.
7 SK. Start kit can be used with all -A single phase models only. Is not used or available for -B or -C three phase models.
8 ODT. Outdoor thermostat is adjustable from 0 to 50°F. It is suitable for use as a compressor cut-off thermostat.
9 DDC. Incorporates 4 additional sensors: discharge air temperature, indoor blower airflow, compressor current, and dirty filter. These sensing devices function to input analog data
such as temperature, as well as digital data such as airflow, compressor status or filter status.
“V” control module should be ordered in conjunction with direct digital controller (DDC) model TCS22. Refer to DDC specification sheet S3280 for more information.
Use CMA-24 for Model WA423.
Use CMA-23 for Models WA253.

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 equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians.
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
air conditioning 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. See Page 3 for information on codes and
standards.
Size of unit for a proposed installation should be based
on heat loss calculation made according to methods of
Air Conditioning Contractors of America (ACCA). The
air duct should be installed in accordance with the
Standards of the National Fire Protection Association
for the Installation of Air Conditioning and Ventilating
Systems of Other Than Residence Type, NFPA No.
90A, and Residence Type Warm Air Heating and Air

DUCT WORK
FILTERS
All duct work, supply and return, must be properly sized
for the design air flow 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.
A 1-inch throwaway filter is supplied with each unit.
The filter slides into position making it easy to service.
This filter can be serviced from the outside by removing
the service door. A 1-inch washable filter and 2-inch
pleated filter are also available as optional accessories.
The internal filter brackets are adjustable to
accommodate the 2-inch filter by loosening two (2)
screws on each bracket assembly and sliding the
brackets apart to the required width and retightening the
four (4) screws.
Refer to Table 9 & 9A for maximum static pressure
available for duct design.
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 one inch 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 inch clearance to combustible material for the
first three feet of duct attached to the outlet air frame is
required. See Wall Mounting Instructions and Figures 3
and 4 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 inch.
Any grille that meets with 5/8 inch louver criteria may
be used. It is recommended that Bard Return Air Grille
Kit 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 filter grille, filters must be of sufficient 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.
FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in
the service panel.
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 2.
All capacity, efficiency and cost of operation
information as required for Department of Energy
“Energyguide” Fact Sheets is based upon the fresh air
blank-off plate in place and is recommended for
maximum energy efficiency.
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 INSTRUCTIONS
WALL MOUNTING INFORMATION
1. Two holes for the supply and return air openings
must be cut through the wall as shown in Figure 3.
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.
WARNING
Failure to provide the 1/4 inch clearance
between the supply duct and a combustible
surface for the first 3 feet of duct can result in
fire causing damage, injury or death.
4. Mount bottom mounting bracket.
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 is provided
for ease of installation, but is not required.
2. The unit itself is suitable for 0 inch clearance, but
the supply air duct flange and the first 3 feet of
supply air duct require a minimum of 1/4 inch
clearance to combustible material. If a combustible
wall, use a minimum of 30½" x 10½" dimensions for
sizing. However, it is generally recommended that a
1-inch clearance is used for ease of installation and
maintaining the required clearance to combustible
material. The supply air opening would then be
32" x 12". See Figures 3 and 4 for details.
3. Locate and mark lag bolt locations and bottom
mounting bracket location. See Figure 3.
5. Hook top rain flashing under back bend of top. Top
rain flashing is shipped secured to the right side of
the back.
6. Position unit in opening and secure with 5/16 lag
bolts; use 7/8 inch diameter flat washers on the lag
bolts.
7. Secure rain flashing 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.
9. On side-by-side installations, maintain a minimum
of 20 inches clearance on right side to allow access
to control panel and heat strips, and to allow proper
airflow to the outdoor coil. Additional clearance
may be required to meet local or national codes.

WIRING – MAIN POWER
WIRING – LOW VOLTAGE WIRING
Refer to the unit rating plate for wire sizing information
and maximum fuse or “HACR” type circuit breaker
size. Each outdoor unit is marked with a “Minimum
Circuit Ampacity”. This means that the field wiring
used must be sized to carry that amount of current.
Depending on the installed KW of electric heat, there
may be two field 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.
230/208V, 1 phase and 3 phase equipment 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:
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 field
power circuits required for the various models with
heaters.
The unit rating plate lists a “Maximum Time Delay
Relay 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 motor.

START UP
IMPORTANT INSTALLER NOTE
PHASE MONITOR
For improved start up performance wash the indoor coil
with a dish washing detergent.
All units with three phase scroll compressors are
equipped with a 3 phase line monitor to prevent
compressor damage due to phase reversal.
HIGH PRESSURE SWITCH
The WA381, WA484, WA491 and WA602 models are
supplied with a remote reset high 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,
verification of proper rotation must be made.
Verification 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.
Verification 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 one 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 ZR compressors are wired identically
internally. As a result, once the correct phasing is
determined for a specific 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.
Manual 2100-398C
Page
16 of 21
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.
CONDENSER FAN OPERATION
The condenser fan motor on 230/208 volt, one and three
phase, 60 HZ units is a two-speed motor that comes
factory wired on high speed for peak performance. If
ambient conditions permit, it can be reconnected to low
speed (red wire) for lower sound level. See wiring
diagram.
50 HZ models must have fan wired on low speed.
These models are factory wired on low speed.
SERVICE HINTS
1. Caution homeowner to maintain clean air filters at
all times. Also, not to needlessly close off supply
and return air registers. This reduces airflow
through the system, which shortens equipment
service life as well as increasing operating costs.
2. Switching to heating cycle at 75° F or higher outside
temperature may cause a nuisance trip of the remote
reset high pressure switch. Turn thermostat off then
on to reset the high pressure switch.
3. Check all power fuses or circuit breakers to be sure
they are the correct rating.
4. Periodic cleaning of the outdoor coil to permit full
and unrestricted airflow circulation is essential.
SEQUENCE OF OPERATION
COOLING – 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 of constant air circulation. On all 230 volt units
there is a one-minute off delay on the blower motor.
460 volt models do not have an off delay. On a call for
heating, circuit R-W1 make at the thermostat pulling in
heat contact for the strip heat and blower operation. On
a call for second stage heat, R-W2 makes bringing on
second heat contactor, if so equipped.
COMPRESSOR CONTROL MODULE
The compressor control module is standard on the
WA391, WA484, WA491and WA602 models covered
by this manual and is optional on the WA423 model.
The compressor control is an anti-short cycle/lockout
timer with high and low pressure switch monitoring and
alarm relay output.
Adjustable Delay On Make And Break Timer
On initial power up or anytime power is interrupted to
the unit, the delay on make period begins, which will be
2 minutes plus 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 or break timer starts and prevents restart until
the delay on break and delay on make periods have
expired.
During routine operation of the unit with no power
interruptions, the compressor will operate on demand
with no delay.
High Pressure Switch and Lockout Sequence
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 delay on
break 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 relay circuit
will energize. Recycling the wall thermostat resets the
manual lockout.
Low Pressure Switch, Bypass, and Lockout
Sequence
If the low pressure switch opens for more than 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 relay circuit will energize.
Recycling the wall thermostat resets the manual lockout.
Alarm Relay Output
Alarm terminal is output connection for applications
where alarm relay is employed. 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 fixed by specific air
conditioner or heat pump unit model. The
lockout features, both soft and manual, are a
function of the Compressor Control Module.

Limited Warranty
(For units applied within the United States, Canada and Mexico)
Limited Warranty To Original Purchaser
Bard Manufacturing Company, Inc. Bryan, Ohio 43506 warrants to you, the original purchaser, that your Bard product will be free from defects in
materials and workmanship when used under normal conditions from the installation date through the time periods outlined in the “Duration of Warranty”
section (see reverse side).
Proof Of Purchase
You must be able to show us the date on which you purchased your product when you make a claim under this warranty. Your owner’s registration card
filed with us or your contractor’s invoice, bill of sale, or similar document is sufficient. If you can not show us the actual date of purchase, the time
periods in this warranty will start on the date that we shipped your Bard product from our factory.
What This Warranty Does Not Cover (Also see Duration of Warranty on reverse side)
This warranty does not cover defects or damage caused by:
1. Alterations not approved by us; improper installation (including over or under sizing), improper repairs, or servicing; or improper parts and
accessories not supplied by us.
2. Misuse or failure to follow installation and operating instructions (including failure to perform preventative maintenance) or limitations on the rating
plate.
3. Operation in a corrosive atmosphere (such as acids, halogenated hydrocarbons or coastal environmental conditions).
4. Parts that must be replaced periodically (such as filters, oil nozzles, mist eliminators, WERV belts, pile seals, etc.).
5. Improper fuel or electrical supply (such as low voltage, voltage transients, and power interruption).
6. Accidents or other events beyond our reasonable control (such as storm, fire, or transportation damage).
7. Defects that happen after
(a) Anyone has tampered with the product.
(b) The product has been improperly serviced according to accepted trade practices;
(c) The product has been moved from its original place of installation; or,
(d) The product has been damaged by an event beyond Bard’s control (See also No. 5 above).
8. Consequential damages (such as increased living expenses while the product is being repaired). Some states do not allow the exclusion or
limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.
9. This warranty does not cover units installed on over-the-road trucks, vans and trailers.
10. Cost of service call at installation site to diagnose causes of trouble, labor to replace defective component or transportation costs for
replacement parts.
11. Contact Bard Manufacturing Company, Inc. for specific warranty exclusions on products installed outside of the United States, Canada and Mexico.
Your Responsibilities
You are responsible for
1. Preventative maintenance of the product (such as cleaning and replacement of filters, nozzles and other consumable parts).
2. Insuring that the instruction manual is followed for care and use of your product.
3. Insuring that your product is installed by a competent, qualified contractor, following all local and national codes, and industry standards.
What We Will Do About A Defect
We will either repair or replace the defective part only. Replacement parts may be reconditioned parts. The warranty for the repaired or replaced
part will last only for the remainder of the warranty period for the original part. For Heat Exchangers that are no longer available, we will give you credit
equal to the then current retail price of an equivalent Heat Exchanger.
Defective parts and a properly completed Bard parts warranty form must be returned to a Bard distributor to be eligible for a warranty credit or
replacement.
We will not pay or be responsible for labor or defective/replacement part transportation costs or delays in repairing or failures to complete repairs
caused by events beyond our reasonable control.
What You Must Do
1. Tell your heating and air conditioning contractor as soon as you discover a problem and have the contractor make repairs.
2. Pay for all transportation, related service labor, diagnostic charges, refrigerant, refrigerant recovery and related items.
Service
If your product requires service, you should contact the contractor who installed it or the contractor that has been providing the product’s
preventative maintenance and repair service. You may find the installing contractor’s name on the product or in your Owner’s packet. If you do
not know who that is, you should contact a competent, qualified contractor to make the repairs. If in doubt, you should contact the nearest distributor
that handles Bard products (see telephone pages). Please note that contractors and distributors that handle Bard products are independent contractors
and distributors, and therefore, are not under the direction of Bard Manufacturing Company, Inc.
Only Warranty
This is the only warranty that we make. There are no other express warranties. All implied warranties are limited in duration to the duration of the
applicable written warranty made above.
Some states do not allow limitations on how long an implied warranty lasts, so the above limitation or exclusion may not apply to you.
Other Rights
This warranty gives you specific legal rights and you may have other rights which vary from state to state.
