GENERAL INFORMATION
Free Cooling Unit System
This Bard Free Cooling Unit System is composed of
WR Series wall-mounted air conditioners matched with
an LC6000 lead/lag controller. The wall mounts are
specifically engineered for telecom/motor control center
rooms.
NOTE:
The LC6000 lead/lag controller and WR Series
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 WR Series wall-
mount units. They are a complete system, and
must be used together.
Wall-Mount Air Conditioner Units
The WR Series wall-mount units operate on VAC power.
The 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.
Controller
LC6000 controller and accessories included are
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
for information
on codes and standards.

LC6000 Series
* 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.
