Wall-Mount Air Conditioner Units
The MULTI-TEC units will supply 100% of rated
cooling airflow in freecooling mode with ability to
exhaust the same amount through the unit itself
without any additional relief openings in the shelter.
MULTI-TEC units are available with optional electric
heat and/or dehumidification.
Single Unit Operation
A th-TUNE stand-alone controller (Bard P/N 8403-
088) can be used in place of the LC6000 controller
when only one MULTI-TEC wall-mount air conditioner
is being installed. If using a th-TUNE stand-alone
controller instead of the LC6000 controller, the alarm
logging and remote communication capabilities of the
LC6000 controller will not be available. See th-TUNE
manual 2100-678 for information on installing and
setting up a th-TUNE stand-alone controller for single
unit operation. A TEC-EYE hand-held diagnostic tool
is required to program the wall-mount unit for th-
TUNE stand-alone controller operation. The th-TUNE
stand-alone controller and TEC-EYE diagnostic tool
are available as a kit (Bard P/N 8620-264).
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
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.

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.
