The Bard Wall-Mount Air Conditioner with Left Side Control Panel is
designed to provide complete service access (i.e. compressor, electric heat
strip and electrical controls) when two units are mounted side by side with
minimal space between. The left side unit is the ideal product for
telecommunication and over-the-road medical and communication vans
requiring two wall-mount air conditioners be mounted side by side by using
a WL (left side access) unit and a WA (right side access) unit on the same
building. Factory or field installed accessories are also available to meet
specific job requirements.
All packages are designed
to meet your specific
ventilation requirements
utilizing one of five
ventilation options for the
product. The ventilation
package is mounted within
the unit eliminating the need
for an exterior mounted
hood or damper assembly
on the unit. All assemblies
can be factory installed,
installed in the field at time
of installation or as a retrofit
system after installation.
