CAUTION
Electrical shock hazard.
Cut hazard.
Have a properly trained individual perform
these tasks.
Wear gloves to avoid contact with sharp
edges.
Failure to do so could result in electric shock
or death.
Failure to do so could result in personal injury.
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.
Manual2100-639
Page
4 of 28
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
Conditioning Systems, NFPA No. 90B. Where local
regulations are at a variance with instructions, installer
should adhere to local codes.
DUCT WORK
FILTERS
All duct work, supply and return, must be properly
sized for the design airflow 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 2" pleated MERV 8 is standard with each unit. The
filter slides into position making it easy to service. This
filter can be serviced from the outside by removing the
filter access panel.
Refer to Table 5 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.
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.
For the H Model Series 36-60, a 1/4" clearance to
combustible material for the first 3' of duct attached
to the outlet air frame is required. See Wall
Mounting Instructions and Figures 2A-C and Figure
3 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 Kit RG2W thru RG5W or RFG2W thru RFG5W
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.

INSTALLATION
WALL MOUNTING INFORMATION
Clearances Required for Service Access and
Adequate Condenser Airflow
1. Two holes for the supply and return air openings
must be cut through the wall as shown in Figure 2.
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 flange and the first 3' of supply
air duct require a minimum of 1/4" clearance
to combustible material for Model Series H36,
H42, H48 and H60. However, it is generally
recommended that a 1" clearance is used for
ease of installation and maintaining the required
clearance to combustible material. See Figures
2A-C for details on opening sizes.

NOTE: For side by side installation of two (2) H**A models there
must be 20" between units. This can be reduced to 15" by using
a H**L model (left side compressor and controls) for the left unit
and H**A (right side compressor and controls) for right unit.
3. Locate and mark lag bolt locations and bottom
mounting bracket location (see Figure 2).
4. Mount bottom mounting bracket.
5. Hook top rain flashing, attached to front-right
corner of supply flange for shipping, under back
bend of top.
6.Position unit in opening and secure with 5/16 lag
bolts; use 7/8" diameter flat washers on the lag
bolts.
7. Secure rain flashing to wall and caulk across entire
length of top (see Figure 2).
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" 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.
10.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 other large object can
cause obstructions to the condenser discharge
air. Recirculation or reduced airflow caused by
obstructions will result in reduced capacity,
possible unit pressure safety lockouts and reduced
unit service life.

WIRING – LOW VOLTAGE WIRING
Filter Switch Adjustment
Low Voltage Connection
1. Turn off unit power.
These units use a 24-volt AC low voltage circuit.
Tables 11 – 13 on pages 23 – 25 show the low voltage
connections for units operated with the MV Series
controller, MC Series controller or connected directly to
a cooling/heating thermostat.
2. Remove upper front door. Front screws on unit top
can be removed for ease of removing upper front
door.
All models are equipped with 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:
TAPRANGE
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).
DIRTY FILTER SWITCH AND RELAY
These units include an adjustable dirty filter indicator
switch. This switch if connected to normally closed
contacts on the filter relay wired to terminals 10 and
11 on the low voltage terminal block.
3. Locate filter switch on control panel side next to
blower assembly.
4. Remove single phillips head screw on front of
cover. Remove cover.
5. Set pressure by adjusting knob. Do not adjust

or non-functionality.
6. Replace cover.
7. Replace upper front door.
8. Turn on unit power.
ECONOMIZER FAIL TIME DELAY RELAY
NOTE: Applies only to units with economizers.
These units employ a time delay relay to open the
nomally closed contacts at terminals 12 and 13 on the
low voltage terminal block. This will activate an alarm
signal on the MV Series controller. The time delay is set
to 500 seconds as a factory default. Avoid adjustment
to settings lower than 180 seconds.

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).
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.
WARNING
Failure to conform to these practices could
lead to damage, injury or death.
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 significant 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.
SAFETY PRACTICES
1. Never mix R-410A with other refrigerants.
2. Alwasys 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 flammable.
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 fill 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 significantly
at warmer temperatures. Once a cylinder or line is
full of liquid, any further rise in temperature will
cause it to burst.
IMPORTANT INSTALLER NOTE
For improved start up performance wash the indoor coil
with dishwashing detergent.

HIGH PRESSURE AND LOW PRESSURE
SWITCHES
All H**A/H**L wall mounted air conditioner series
models are supplied with a remote reset for the high
and low pressure switches. The first time the high
or low pressure switches are tripped, they will reset
automatically. If tripped a second time, reset the
switches by turning the thermostat off, then back on
again, resetting the compressor control module.
CONDENSER FAN OPERATION
NOTE: Certain models may be equipped with a
low ambient control (LAC), and if so equipped the
condenser fan motor may have a delayed start until
system refrigerant operating pressure builds up.
After starting, the fan motor may or may not cycle
depending upon ambient conditions. This is normal
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 unit wiring diagram.
SERVICE HINTS
1. Caution owner/operator to maintain clean air filters
at all times and to not 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. 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 airflow circulation is essential.
SEQUENCE OF OPERATION
COOLING – 24VAC from MV controller at terminal 4 (Y)
pulls in compressor contactor, starting the compressor
and outdoor motor. (See Note under Condenser Fan
Operation if equipped with low ambient control.)
Terminal 9 (G) indoor motor circuit is energized by
the MV controller on any call for cooling operation or
can be energized by manual fan switch on subbase for
constant air circulation. On a call for heating from the
MV controller makes at the relay board 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. See Table 1 on
following page.
COMPRESSOR CONTROL MODULE
The compressor control module (CCM) is standard on
all models covered by this manual. The compressor
Manual2100-639
Page
16 of 28
control module is an anti-short cycle/lockout timer with
high and low pressure switch monitoring and alarm
relay output.
Adjustable Delay-on-Make and Delay-on-Break Timer
On initial power up and any time power is interrupted
to the unit, the delay-on-make period begins, which
is the time set on the potentiometer (delay-on-break
time) plus 10% of the delay-on-break setting. When
the delay-on-make period is complete and the high
pressure switch and low pressure switch are closed, the
compressor contactor is energized. Upon shutdown
(end of the call for cooling), the delay-on-break timer
starts and prevents restart (next call for cooling) until
the delay-on-break period has 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-onbreak 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 or main
power 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 re-energize 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 or main power resets the
manual lockout.
Alarm Relay Output
Alarm terminal is output connection for applications
where alarm relay is employed. This terminal is
powered whenever the 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 unit model. The lockout features,
both soft and manual, are a function of the
compressor control module.
ADJUSTMENTS
Typical Settings for Dual Unit Installation:
Adjustable Delay-on-Make and Delay-on-Break Timer
Unit 1: DOB set at 2 minutes and DOM is 132 seconds
Unit 2: DOB set at 4 minutes and DOM is 144 seconds
The potentiometer is used to select delay-on-break time
from 30 seconds to 5 minutes. Delay-on-make (DOM)
timing on power up and after power interruptions is
equal to 2 minutes plus 10% of delay-on-break (DOB)

PRESSURE SERVICE PORTS
High and low pressure service ports are installed on
all units so that the system operating pressures can
be observed. A pressure table can be found on page
19 covering all models. It is imperative to match the
correct pressure table to the unit by model number.
During routine operation of the unit with no power
interruptions, the compressor will operate on demand
with no delay.
