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. 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.

LV1000 Series
* One remote temperature/humidity sensor and 35' of 5-wire shielded cable with drain are included with
the LV1000 controller. Up to two additional remote temperature/humidity sensors can be purchased and
installed. Temperature-only sensors (Bard P/N 8301-058) may be used instead of the additional temperature/
humidity sensors, but will also need to be purchased separately. Temperature-only sensors require field-
supplied 2-wire shielded cable with drain.

GENERAL INFORMATION
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.
