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
Conditioning Systems, NFPA No. 90B. Where local
regulations are at a variance with instructions, installer
should adhere to local codes.

Manual 2100-647D
Page 4 of 36

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.

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.

For the H Model Series 36-72, 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 3A-D and Figure 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.

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.

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.

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

1. Two holes for the supply and return air openings
must be cut through the wall as shown in Figures
3A-D on pages 9-12.

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, H60 and H72. 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
3A-D for details on opening sizes.

NOTE: For side-by-side installation of two 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 Figures 3A-D).

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.

Position unit in opening and secure with fasteners

6.
sufficient for the application such as 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 Figures 3A-D).

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.

For units with blow through condensers, it is

recommended there be a minimum distance of 10'
between the front of the unit and any barrier or 20'
between the fronts of two opposing (facing) units.

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 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.

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 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

WIRING – LOW VOLTAGE WIRING

Low Voltage Connection

These units use a 24-volt AC low voltage circuit. Tables
11 and 12 on pages 29 and 30 show the low voltage
connections for units operated with the MV Series
controller or connected directly to a cooling/heating
thermostat.

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:

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).

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.

Filter Replacement Procedure

Filter Switch Adjustment

1. Turn off unit power.

2. Remove upper front door. Front screws on unit top
can be removed for ease of removing upper front
door.

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
knob drastically to avoid nuisance alarm signalw
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).

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.

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.

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.

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 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 an extended period of time, the
compressor’s internal protector will trip.

All three phase 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.

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

NOTE: These models are equipped with a low ambient
control (LAC). 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 concerning the 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. A call for heating from the MV
controller pulls in heat contactor, activating 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.

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.

Manual 2100-647D

COMPRESSOR CONTROL MODULE

The compressor control module (CCM) is standard on
all models covered by this manual. The compressor
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 (delay-on-break
factory default is 2 minutes). When the delay-on­make 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 delay­on-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 the output connection for
applications where an alarm relay is employed. This
terminal is powered whenever the compressor is locked
out due to HPC or LPC sequences as described above.

Manual 2100-647D
Page 19 of 36

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

Adjustable Delay-on-Make and Delay-on-Break Timer

The potentiometer is used to select delay-on-break time
from 30 seconds to 5 minutes. (The delay-on-break
factory default is 2 minutes.) Delay-on-make (DOM)
timing on power up and after power interruptions is
equal to delay-on-break time plus 10% of delay-on­break (DOB) setting:

0.5 minute (30 seconds) DOB = 123 second DOM

1.0 minute (60 seconds) DOB = 126 second DOM

2.0 minute (120 seconds) DOB = 132 second DOM

3.0 minute (180 seconds) DOB = 138 second DOM

4.0 minute (240 seconds) DOB = 144 second DOM

5.0 minute (300 seconds) DOB = 150 second DOM

During routine operation of the unit with no power
interruptions, the compressor will operate on demand
with no delay.

Typical Settings for Dual Unit Installation:

Unit 1: DOB set at 2 minutes and DOM is 132 seconds
Unit 2: DOB set at 4 minutes and DOM is 144 seconds

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
22 covering all models. It is imperative to match the
correct pressure table to the unit by model number.

This unit employs high-flow 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 first 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.

charge being in the system, the charge should be removed, system evacuated and recharged to serial plate charge
weight.

NOTE: Pressure table based on high speed condenser fan operation. If condensing pressures appear elevated,

check condenser fan wiring. See “Condenser Fan Operation”.
