GENERAL INFORMATION
Free Cooling Unit System
This Bard Free Cooling Unit System is composed of
FUSION-TEC wall-mounted air conditioners matched
with an LV1000 lead/lag controller. The wall mounts
are specifically engineered for telecom/motor control
center rooms.
NOTE: The LV1000 lead/lag controller and FUSION-
TEC wall-mount units are designed specifically
to work together. The controller cannot run
other Bard models or other brands of systems,
nor can other controllers run the FUSION-TEC
wall-mount units. They are a complete system,
and must be used together.
Wall-Mount Air Conditioner Units
The FUSION-TEC units operate on VAC power.
units will supply 100% of rated cooling airflow in free
cooling mode with ability to exhaust the same amount
through the unit itself without any additional relief
openings in the shelter.
Each of these units are fully charged with refrigerant
and may have optional auxiliary heat.
The
Controller
LV1000 controller and accessories included shown
below.
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 without duct work. Flanges
are provided for transition from unit to wall grilles. A
field-supplied wall sleeve may be necessary between
the supply and return flanges and grilles.
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 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 Additional Publications on page 4 for
information on codes and standards.

Minimum Clearance
Counter flow wall-mount air conditioner models have
a removable lower front service panel that allows
access to the control panel, blower, compressor, circuit
breakers and heat strip. There is a hinged access panel
on both sides for filter change and evaporator coil
service.
The upper side panel is removable to allow access
to condenser fan, condenser coil and filter drier. The
design allows for installations to place units within
close proximity without complicating maintenance and
repair.
To maintain full serviceability, side-by-side installations
require 15" of clearance between units.
The condenser discharge air exits through the top
of the unit. Although this reduces the potential for
recirculation, it is still critical to system performance
that any obstruction, shrubbery or structure adhere to
minimum clearances listed (see Table 1).
For overhangs not exceeding 12" from exterior wall,
minimum allowable clearance from top of unit
to bottom of overhang should be no less than 5".
For overhangs greater than 12" from exterior wall,
minimum allowable clearance from top of unit to
bottom of overhang should be no less than 10".
Clearance to Combustibles
The unit itself is suitable for 0" clearance, but the
supply air flange requires a minimum of 1/4" clearance
to combustible material. However, it is generally
recommended that a 1" clearance is used for ease of
installation and maintaining the required clearance
to combustible material. See Figure 8 on page 13 for
details on opening sizes.
!
WARNING
Fire hazard.
Maintain minimum 1/4" clearance between the
supply ange and combustible materials.
Failure to do so could result in re causing

WALL-MOUNT UNIT MOUNTING
Mounting the Units
!
WARNING
Heavy item hazard.
Use more than one person to handle unit.
Failure to do so could result in unit damage or
serious injury.
NOTE: It may be best to spot some electrical knockouts
(such as those located on the sides of the
wall-mount unit) before units are mounted and
access is unavailable or limited (see Figure 2 to
locate pre-punched knockouts).
Two holes for the supply and return air openings must
be cut through the wall as shown in Figure 8 on page
13. 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. All walls
must be thoroughly inspected to ensure that they are
capable of carrying the weight of the installed unit.
In retrofit (unit replacement) installations, the openings
cut for the original equipment may not line up exactly
with needs of this installation. Modifications may need
to be made, such as increasing or decreasing the size
of the wall cutouts. The existing bolt placement may
not line up in which case the original bolts would need
to be removed or cut away.
These units are secured by full-length mounting flanges
built into the cabinet on each side. An optional bottom
mounting bracket (purchased separately) is available,
but not required.
The unit itself is suitable for 0" clearance, but the
supply air flange requires a minimum of 1/4" clearance
to combustible material. However, it is generally
recommended that a 1" clearance is used for ease of
installation and maintaining the required clearance
to combustible material. See Figure 8 for details on
opening sizes.
IMPORTANT: When removing the shipping pallet from
beneath the wall unit, do not loosen or remove any of
the screws from either side of the unit.
1. Locate and mark lag bolt locations on both sides
and location for optional bottom mounting bracket,
if desired (see Figure 8).
NOTE: Top rain flashing is attached to back of unit
for shipping purposes. Be sure to remove this
flashing before installing unit.
2. If desired, hook top rain flashing under back bend
of top.
3. Position unit in opening and secure with fasteners
sufficient for the application such as 5/16" lag/
anchor bolts; use 7/8" diameter flat washers on
the lag bolts. It is recommended that a bead of
commercial grade outdoor silicone sealant caulk be
placed behind the side mounting flanges.
NOTE: Opening and removing the filter access door
from each side may make fastening unit to wall
easier.
4. Secure optional rain flashing to wall and caulk
around entire unit (see Figure 8).
5. 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.
6. Four plastic drain hoses extend from the condenser
and evaporator drain pans. The drain hoses are
secured to fittings mounted to the unit base.
NOTE: At the time of installation, Bard highly
recommends prefilling of the traps on both of
the indoor drain pan hoses to ensure proper unit
drainage at start. The water traps can easily
be seen with the front service panel removed.
To fill traps, pour water into both sides of
evaporator drain pan until the drain hoses are
visibly full (see Figure 3).
A unique feature of the FUSION-TEC is the ability to
hang the front service panel on the unit in a position
that allows full access to the control panel (see
Figure 4) while the unit remains fully functional for
troubleshooting and testing. To do this, remove the
panel and hook top lip of panel into bottom channel
of control panel. For added front panel stability, use
several of the screws that were removed to temporarily
connect the panel to the unit.

Supply Air Grill Installation
Bard model SGR-5W grille is custom designed for
utilization with Bard wall-mount unit HR**AP* for
optimizing the air flow pattern and distribution to
minimize recirculation issues, and optimizing airflow
patterns within the shelter. It is engineered to ensure
that the distributed air is forced in a downward and
outward direction to eliminate obstructions and such
from causing the distributed air from stratifying close
to the unit and getting drawn back into the return air
opening. With the optimized air pattern, the shelter
should experience distributed air at the opposite end of
the room.
To accomplish this, the grille has two special features:
1. The grille has a specialty fold-out diverter on
the backside of the grille that directs the supply
airflow in an outward pattern, thereby eliminating
the potential for the obstruction of supply air if
FIGURE 5
Fold-Out Diverter
equipment would be directly mounted in front of
the unit. The rear deflectors must be folded out and
secured by the installer with the supplied screws
(see Figure 5).
2. The grille is also equipped with downward curved
diverter blades to ensure a smooth and efficient
means of directing the air pattern in a downward
pattern, and away from being drawn back into
the return air opening. The curved diverter blades
are shipped in the flat position and need to be
folded out to between 75-90° (best tuned to each
individual structure). See Figures 6 and 7.

WARNING
Electrical shock hazard.
Have a properly trained individual perform
these tasks.
Failure to do so could result in electric shock
or death.
Main Power Wiring
Refer to the unit rating plate or Table 3 for wire sizing
information and maximum fuse or circuit breaker size.
Each outdoor unit is marked with a “Minimum Circuit
Ampacity”. 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 rating 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 unit rating plate and Table 3 list 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 circuit breaker or
fuse that is to be used with the equipment. The correct
size must be used for proper circuit protection and also
to ensure that there will be no nuisance tripping due to
the momentary high starting current of the compressor
motor.
The main unit circuit breaker disconnect access is
located on the front panel of the unit. Located at the
upper right corner of this panel is the rubber circuit

Unit Control Voltage Wiring
230/208V 1 phase and 3 phase equipment use dual
primary voltage transformers. All equipment leaves the
factory wired on 240V tap. It is very important that
the correct voltage tap is used. For 208V operation,
reconnect from 240V to 208V tap (see Figure 15 on
page 18). The acceptable operating voltage range for
the 240 and 208V taps are: 240V Tap (253 – 216)
and 208 Tap (220 – 197).
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.

PRELIMINARY START UP
Running in Stand Alone (Orphan) Mode
With the AC breakers turned on, each FUSION-TEC
wall-mount unit has the capability to run without the
LV1000 controller attached—this feature is called
stand alone or orphan mode. This keeps the shelter
between 60°F and 79°F (factory default settings) by
the use of the factory-installed return air sensor in
each wall-mount unit. In stand-alone mode, the wall
unit uses a continuous blower setting to circulate room
air into the return air inlet and uses the return air
temperature sensor to control room temperature.
The wall-mount unit can be turned on and off with
the TEC-EYE hand-held diagnostic tool. When ON is
chosen, the wall unit will heat or cool. The blower will
continue to run when OFF is chosen. If the wall unit is
turned OFF by the TEC-EYE while in stand alone mode
and power is interrupted, when repowered the blower
will not run until the wall unit is turned back ON by the
TEC-EYE.
To turn the unit on or off with TEC-EYE:
1. Connect the TEC-EYE diagnostic tool to the control
board located in the unit.
2. Press MENU key to go to the Main Menu screen.
3. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
4. Press UP or DOWN keys to scroll to On/Off; press
ENTER key.
5. Press UP or DOWN keys to change value from On
to Off or from Off to On.
6. Press ESCAPE key several times to return to Main
Menu screen.
To verify or change the wall-mount unit cooling and
heating setpoints in stand alone mode:
1. Connect the TEC-EYE diagnostic tool to the control
board located in the unit.
2. From the Status screen, press UP or DOWN key
until Quick Menu displays Setpoints (SET) icon.
Press ENTER key.
3. Press ENTER key to scroll to the selected choice
(see Figure 16).
4. Press UP or DOWN key on desired value until value
displays correctly.
5. Press ENTER key to save and scroll to next
parameter.
6. Press ESCAPE key until Main Menu screen is
displayed.
FIGURE 16
Cool and Heat Setpoints
During installation, the ability to run in stand alone
mode allows deactivation of one of the existing, older
wall-mount units, while keeping the shelter cool with
the other unit still operating. Once the first of the Bard
FUSION-TEC wall-mount units is installed, orphan
mode can be enabled early in the installation—keeping
the climate inside the shelter stable and the installers
comfortable while the remainder of the older equipment
is removed and the remaining Bard FUSION-TEC wallmount units and LV1000 controller are installed.
To ensure units will go into stand alone mode,
disconnect the plug marked R-T-/R+T+/GND on the
control board located in the wall-mount unit. Be sure
to reconnect the plug before operating the wall-mount
unit as part of the Bard Free Cooling Unit System.
Additionally, should any or all of the FUSION-TEC
wall-mount units lose communication with the LV1000
controller (such as during maintenance), they will
continue to serve the shelter’s needs until a repair can
be made.
NOTE: Screenshots shown in this manual reflect
default settings (when applicable).

before servicing.
Failure to do so could result in electric shock
or death.
IMPORTANT: When working with circuit board
components,

electricity shorts to electronic controls.
Bard recommends the use of
LV1000 Controller
The LV1000 controller is part of the Free Cooling
Unit system by Bard. It is used to control up to four
(4) wall-mount air conditioners from one controller.
The microprocessor control provides an easy-to-read
interface with large LCD graphical display. It provides
control for redundancy for the structure and equal wear
on all units. The LV1000 controller is configured for
first on/next on sequence.
Conduit is recommended for all wiring. Route
communication wiring and power supply wiring in their
own separate conduits.
The LV1000 controller is not weatherproof and is
intended for use in weathertight structure.
Mounting the LV1000 Controller
The dimensions of the LV controller are 16" by 12" by
6".
Because the LV1000 controller utilizes a remote
temperature sensor as opposed to one located in the
controller box, the controller itself can be installed in
any indoor location that is suitable, preferably at eye
level. Four (4) mounting holes are provided for mounting
to the wall and holes for conduit connection are provided
in both the base, sides and top of the controller.
Ground case before doing any work or do not connect
power (48VDC) to unit until earth ground is connected.
The LV1000 controller includes a fused power supply
terminal in the terminal block. Before connecting wires
to the terminal block, confirm that the fuse in the fuse
holder is in the proper position (active) as shown in
Figure 18.

Installing Remote Indoor Temperature/Humidity Sensor(s)
One remote indoor temperature/humidity sensor and 35' of 18 gauge 5-conductor shielded cable is included with the
controller. This sensor must be installed for proper operation. Mount the temperature/humidity sensor in a location
least likely to be affected by open doors, rack-mounted fans, radiant heat sources, etc. Location height should be
approximately 60" above the floor. The sensor should be installed on a 2" x 4" junction box to allow for control wire
conduit (see Figure 19). Use shielded cable to connect to controller.

2. Connect the other end of the shielded cable to the sensor
terminals. Be sure wires are connected to proper terminals
as shown in table above. Sensor jumpers need to be
positioned for 0-1 V. With sensor oriented as shown in
image to right, move both jumpers to left position (DP1 and
DP2 set to OFF).
This applies to all temperature/humidity sensors connected
to the LV controller.
Sensor is best mounted on a junction box, and it is
recommended that the cable be in conduit.

Communication Wiring
Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figures 21,
22 or 23 (page 26). The daisy chain does not need to follow the addressing order. The communication wire should
be 2-wire, 18 gauge shielded cable with drain. Any color can be used. Be sure to match "+" and "-" symbols on
controller terminal blocks to prewired unit control terminal block (see Figures 25 and 26 on pages 28 and 29).
Attach communication wire filters as shown in Figures 21, 22 or 23. Filters go inside the unit or controller box; they
are shown out of unit for identification purposes only. Do not run communication wiring in same conduit as supply
wiring. Route communication wiring and power supply wiring in their own separate conduits.

The LV1000 controller is powered by -48VDC from the shelter. A field-supplied 5 amp DC circuit breaker is required.
Field-supplied supply wiring should be minimum 16 gauge, maximum 14 gauge (see Figure 27). A reliable earth
ground must be connected in addition to any grounding from conduit. Grounding posts are included with the
controller for this purpose; install as shown in Figure 28. Failing to ground the controller box properly could result in
damage to the equipment.
FIGURE 27

TEC-EYETM Hand-Held Diagnostic Tool
The microprocessor control used in the FUSION-TEC
wall-mount air conditioners allows for complete control
and monitoring through the use of the provided TECEYE hand-held monitor.
The menu driven interface provides users the ability
to scroll through two menu levels: Quick Menu and
Main Menu. The menus permit the user to easily view,
control and configure the unit. See FUSION-TEC
Service Manual 2100-670 for more information on
using the TEC-EYE.
The TEC-EYE connects to the wall-mount unit control
board via an RJ11 modular phone connector as shown
in Figure 30.
When not being used, the TEC-EYE hand-held
diagnostic tool should be stored inside or near the
LV1000 controller. Do not let the TEC-EYE leave the
shelter.
