GENERAL INFORMATION

Air Conditioning System

This Bard air conditioning system is composed of 
FUSION-TEC 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 FUSION-

TEC WR Series wall-mount units are designed 

specifically to work together. The controller 

cannot run other brands of systems, nor can 

other controllers run the FUSION-TEC WR 

Series wall-mount units. They are a complete 

system, and must be used together. 

Wall-Mount Air Conditioner Units

The 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 have optional auxiliary heat.

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.
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.

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.
