GENERAL INFORMATION
Reference Supplemental Instructions
7960-801 for complete details.
Free Cooling System
The Bard free cooling unit system is composed of
MULTI-TEC wall-mounted air conditioners matched
with an LC6000 supervisory controller or Bard th-
Tune 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
unit is installed, the LC6000 controller must be
matched with the air conditioning units. The wall
mounts 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.
Wall-Mount Air Conditioner Units
The MULTI-TEC units are designed to supply full
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. In
the event that free cooling operation cannot satisfy the
load requirements, mechanical cooling will be utilized
to assist in cooling the shelter.
MULTI-TEC units are available with electric heat and
dehumidification options.
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 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
