GENERAL INFORMATION
Cooling System
This Bard cooling system is composed of MULTI-TEC, FUSION-TEC WR Series and/or MEGA-TEC wall-mounted
air conditioners matched with an LC6000 controller or Bard th-Tune stand-alone controller (th-Tune can only be
used with MULTI-TEC units). If only one wall-mounted air conditioner is being used, it can be matched with either
the LC6000 or a th-Tune stand-alone controller (if applicable). If more than one wall-mount unit is installed, the
LC6000 controller must be matched with the air conditioning units. The wall-mount units are specifically engineered
for equipment cooling applications.
NOTE: The LC6000 controller and MULTI-TEC, FUSION-TEC WR Series and MEGA-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, FUSION-TEC WR Series or MEGA-TEC wall-mount units. They are a
complete system, and must be used together.

One remote temperature/humidity sensor is 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. Additional temperature/humidity sensors require field-supplied 5-wire 18 gauge shielded
cable. Temperature-only sensors require field-supplied 2-wire 18 gauge shielded cable.

The equipment covered in this manual is to be installed
by factory trained and certified, experienced service and
installation technicians.
These instructions 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.
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.
Additional Publications
These publications can help when installing the air
conditioner. They can usually be found at the local
library or purchased directly from the publisher. Be
sure to consult the current edition of each standard.
ANSI Z535.5 Definitions:
DANGER: Indicate[s] a hazardous situation which, if
not avoided, will result in death or serious injury. The
signal word “DANGER” is to be limited to the most
extreme situations. DANGER [signs] should not be used
for property damage hazards unless personal injury risk
appropriate to these levels is also involved.
WARNING: Indicate[s] a hazardous situation which,
if not avoided, could result in death or serious injury.
WARNING [signs] should not be used for property
damage hazards unless personal injury risk appropriate
to this level is also involved.
CAUTION: Indicate[s] a hazardous situation which, if
not avoided, could result in minor or moderate injury.
CAUTION [signs] without a safety alert symbol may be
used to alert against unsafe practices that can result in
property damage only.
NOTICE: [this header is] preferred to address practices
not related to personal injury. The safety alert symbol
shall not be used with this signal word. As an
alternative to “NOTICE” the word “CAUTION” without
the safety alert symbol may be used to indicate a
message not related to personal injury.

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 this air conditioning
system. 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 a weathertight structure.
IMPORTANT: When connecting this product from a
remote location, ensure that the network
connection is secure and reliable.
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 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 Figure 2.

The LC6000 controller is powered by 120, 208 or 240 volts from the shelter. Field-supplied supply wiring should
be minimum 16 gauge, maximum 14 gauge (see Figure 3). A reliable earth ground must be connected in addition
to any grounding from conduit. Grounding bolts and nuts are included with the controller for this purpose; a 2 hole
grounding lug must be field supplied. Install as shown in Figure 4. Failing to ground the controller box properly could
result in damage to the equipment.

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. 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 (and any additional sensors) must be
configured properly with the controller as shown in Step 2 on page 8. An additional remote indoor temperature-
only sensor can be purchased and installed in Zone 1. 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 per
zone) will need to be purchased and installed in the additional zones. All installed sensors must be enabled in the
controller menu (see Configure Sensors in system installation instructions included with the wall-mount unit).
FIGURE 6
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
added to Zones 2 and 3 (one per zone). Be sure the sensors are connected to the proper terminals on the terminal

Communication Wiring
The steps outlined on the following pages show how to connect the communication wiring to the LC controller.
Communication wire connections to the wall-mount unit vary with the different units. See the system installation
instructions included with the wall-mount unit for information on connecting the communication wiring to the wallmount unit(s).
FIGURE 9
Communication Wiring: Termination at the Controller
1. Using the field-provided shielded cable, make a small service loop after entering the controller and attach the provided
EMI filter at the intersection of the loop.
2. Connect one wire to terminal #56 (negative), the other wire to terminal #57 (positive) and the drain wire to ground
terminal #60.
