GENERAL INFORMATION
Free Cooling Unit System
This Bard Free Cooling Unit System is composed of
MULTI-TEC wall-mounted air conditioners matched
with an LC6000 supervisory controller or Bard thTUNE stand-alone controller. If only one wall-mounted
air conditioner is being used, it can be matched with
either the LC6000 supervisory controller or a th-TUNE
stand-alone controller. If more than one wall mount is
installed, the LC6000 controller must be matched with
the air conditioning units. The wall-mount units are
specifically engineered for telecom/motor control center
rooms.
NOTE: The LC6000 supervisory controller and
MULTI-TEC wall-mount units are designed
specifically to work together. The controller
cannot run other brands of systems, nor can
other controllers run the MULTI-TEC wall-mount
units. They are a complete system, and must be
used together.
LC6000 Series
Wall-Mount Air Conditioner Units
The
MULTI-TEC
cooling airflow in freecooling mode with ability to
exhaust the same amount through the unit itself
without any additional relief openings in the shelter.
MULTI-TEC units are available with optional electric
heat and/or dehumidification.

Controller
LC6000 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.

Controller
* One remote temperature/humidity sensor and 35' of 5-wire shielded cable are included with the LC6000
controller. If the site in which the LC6000 controller will be used has more than one zone (maximum three
zones per LC6000), additional remote temperature/humidity sensors (one sensor per zone) will need to be
purchased and installed in the additional zones. One additional temperature-only sensor (Bard P/N 8301-
058) may also be used in Zone 1 but will also need to be purchased separately. Temperature-only sensors
require field-supplied 2-wire shielded cable with drain.

Single Unit Operation
A th-TUNE stand-alone controller (Bard P/N 8403-088) can be used in place of the LC6000 controller when only
one MULTI-TEC wall-mount air conditioner is being installed. If using a th-TUNE stand-alone controller instead
of the LC6000 controller, the alarm logging and remote communication capabilities of the LC6000 controller
will not be available. See th-TUNE manual 2100-678 for information on installing and setting up a th-TUNE
stand-alone controller for single unit operation. A TEC-EYE hand-held diagnostic tool is required to program the
wall-mount unit for th-TUNE stand-alone controller operation. The th-TUNE stand-alone controller and TEC-EYE
diagnostic tool are available as a kit (Bard P/N 8620-264).

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 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 for information
on codes and standards.
Sizing of systems for proposed installation should be
based on heat loss and heat gain calculations made
according to methods of Air Conditioning Contractors of
America (ACCA). The supply flange 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.
Shipping Damage
Upon receipt of equipment, the cartons 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.
These units must remain in upright position at all
times.

SITE PREPARATION
Model Identification
Identify the specific model using the model
nomenclature information found in Figure 1 and
the model/serial tag found on the unit. See Figure 2
on page 11 for dimensions and critical installation
requirements.
New Shelter Installation vs. Retrofit
Installation
These installation instructions cover both new shelter
installations and retrofit installations. Each installation
is unique and may require special accommodations and
modifications. Although Bard Manufacturing follows a
long-established tradition of manufacturing equipment
using industry standard dimensions for building
penetration, it is occasionally necessary to move or
enlarge supply and return openings when replacing
non-standardized equipment in a retrofit application.
Minimum Clearance
Wall-mount air conditioners are available in both righthand access models and left-hand access models.
Right-hand access models have the heat strip access
panel, external circuit breakers access panel and
internal controls access panel on the right side of the
unit. Left-hand access models are a mirror image of the
right-hand access models, and allow two wall-mount
units to be placed in relatively close proximity and yet
still allow complete access for maintenance and repair.
On side-by-side installations, maintain a minimum of
20" clearance on control side to allow access to control
panel and heat strips, and to allow proper airflow to the
outdoor coil. For installations where units are installed
with both control panels facing each other (inward),
maintain a minimum of 36" clearance to allow access.
Additional clearance may be required to meet local or
national codes.
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 a 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, such as
these wall-mount units, 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.

WARNING
Fire hazard.
Maintain minimum 1/4" clearance between the
supply air duct and combustible materials in
the rst 3' of ducting.
Failure to do so could result in re causing
damage, injury or death.
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. 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 4A-D on pages 12-15 for details
on opening sizes.

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 Figures
4A-D on pages 12-15. 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
insure 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.
1. These units are secured by full-length mounting
flanges built into the cabinet on each side which
secure the unit to the outside wall surface. 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. 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
4A-D for details on opening sizes.
3. Locate and mark lag bolt locations and location for
optional bottom mounting bracket, if desired (see
Figures 4A-D).
4. Mount bottom mounting bracket (if used).
5. If desired, hook top rain flashing (attached to frontright of supply flange for shipping) under back
bend of top.
6. Position unit in opening and secure with fasteners
sufficient for the application such as 5/16" lag/
anchor/carriage bolts; use 7/8" diameter flat washers
on the lag bolts. It is recommended that a bead
of silicone caulking be placed behind the side
mounting flanges.
7. Secure optional rain flashing to wall and caulk
across entire length of top (see Figures 4A-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. 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.
10. Install outdoor temperature/humidity sensor (see
Figure 3). Remove grommet from base and sensor.
Discard shipping bracket. Place sensor extension
through hole in base under condenser fan and
secure to base with screw.

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 1 (page 20),
Table 2 (page 21) or Table 3 (page 22) 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 Tables 1, 2 and 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 assure that there will be no nuisance tripping due to
the momentary high starting current of the compressor
motor.
Route all field wires to the right of the wire shield as
shown in the circuit routing label found in Figure 9
(and also on the wall-mount units).
See Figure 10 to reference VAC landing points.
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
opening under the disconnect access panel straight
out. This tab will now line up with the slot in the door.
When shut, a padlock may be placed through the hole
in the tab preventing entry.

LOW 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. 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.
For low voltage wiring, an 18 gauge copper, color-coded
cable is recommended.

PRELIMINARY START UP
Running in Stand Alone (Orphan) Mode
With the AC breakers turned on, each MULTI-TEC
wall-mount unit has the capability to run without
the LC6000 controller or th-TUNE connected—this
feature is called stand alone or orphan mode. This
keeps the shelter between 60°F and 77°F (factory
default settings) by the use of the factory-installed
return air sensor in each wall-mount unit. In standalone 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-mount unit will heat or cool. When set
to OFF using the TEC-EYE, the wall-mount unit will not
heat, cool or ventilate.
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 11).
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 11
Cooling and Heating 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
MULTI-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 MULTI-TEC wallmount units and LC6000 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 MULTI-TEC wallmount units lose communication with the LC6000
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).

WARNING
Electrical shock hazard.
Disconnect VAC power supplies before
servicing.
Failure to do so could result in electric shock
or death.
IMPORTANT: When working with circuit board
components,
an anti-static wrist strap to prevent static
electricity shorts to electronic controls.
Bard recommends the use of
LC6000 Controller
The LC6000 controller is part of the Free Cooling
Unit system by Bard. It is used to control up to 14
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.
Conduit is recommended for all wiring. Route
communication wiring and power supply wiring in their
own separate conduits.
The LC6000 controller is not weatherproof and is
intended for use in weathertight structure.
Mounting the LC6000 Controller
The dimensions of the LC controller are 16" x 12" x 6".
Because the LC6000 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 connections are provided
in both the base, sides and top of the controller.
The LC6000 controller includes four fused power
supply terminals in the terminal block. Before
connecting wires to the terminal block, confirm that the
fuse in each of the four fuse holders is in the proper
position (active) as shown in see Figure 13.

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. Locating the sensor between
both return grilles is often the best location, but every installation is unique. 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 14). 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 LC controller.
Sensor is best mounted on a junction box, and it is
recommended that the cable be in conduit.

For proper operation, the remote indoor temperature/humidity sensor must be configured properly with the controller.
An additional remote indoor temperature-only sensor can be purchased and installed in Zone 1. Also, temperature
and humidity sensors can also be purchased and installed in Zones 2 and 3 (one per zone). For information on
remote indoor sensor configuration, see page 26. For each additional sensor installed, be sure to enable the sensor
in the controller menus (see Configure Sensors beginning on page 40).
FIGURE 15
Additional Remote Temperature and Temperature/Humidity Sensor Installation
One additional temperature sensor can be added to Zone 1 and additional temperature/humidity sensors may be
