The Bard WA/L "S" Series is the world's most energy efficient wall mounted
air conditioner featuring a multi-step capacity compressor with
environmentally friendly non-ozone depleting refrigerant.
The Bard Wall-Mount Air Conditioner is a self contained energy efficient
system, which is designed to offer maximum indoor comfort at a minimal
cost without using valuable indoor floor space or outside ground space.
This unit is the ideal product for versatile applications such as: new
construction, modular offices, school modernization, telecommunication
structures, portable structures or correctional facilities. Factory or field
installed accessories are available to meet specific job requirements.
Engineered Features
Multi-Capacity Two-Stage:
Simple thermostatic control
seamlessly stages the compressor
and indoor airflow rate between high
and low capacity operations without
cycling the compressor. This helps
to maximize comfort, humidity
control, energy efficiency and overall
reduction in compressor cycling for
improved system life.
Multi-Step Capacity
Compressor:
Copeland step-capacity scroll
compressors are designed for
increased efficiency, quieter operation
and improved reliability for longer life.
R-410A Refrigerant:
Designed with R-410A (HFC) non-
ozone depleting refrigerant in
compliance with the Montreal
protocol and 2010 EPA requirements.
ECM Indoor Blower Motor:
Features a variable speed motor
providing super-high efficiency, low
sound levels and soft-start
capabilities. The motor is self-
adjusting to provide the proper airflow
rate for the staged capacity, and for
higher static pressure in ducted
installations without user adjustment
or wiring changes.
Aluminum Finned Copper Coils:
Grooved tubing and enhanced
louvered fin for maximum heat
transfer and energy efficiency.
• Complies with efficiency requirements of ANSI/ASHRAE/IESNA 90.1-2010.
• Certified to ANSI/ARI Standard 390-2003 for SPVU (Single Package Vertical Units).
• Intertek ETL Listed to Standard for Safety Heating and Cooling Equipment ANSI/UL
1995/CSA 22.2 No. 236-05, Fourth Edition.
• Commercial Product - Not intended for Residential application.
THE WALL-MOUNT™ STEP CAPACITY AIR CONDITIONERS
Integrated Part Load Value (IPLV) Efficiency Up To 15.3 BTU/WATT
60Hz
Twin Blowers:
Move air quietly. All models feature
variable speed blower motors
providing automatic airflow
adjustment for high static or free
blow (non-ducted) operation at a very
low sound level. Motor overload
protection is standard on all models.
Foil Faced Insulation:
Standard on all units.
Start Kit:
A PTCR compressor start assist
(Positive Temperature Coefficient
Resistor) is standard on all -A single-
phase models to increase system
reliability. This helps to insure
compressor starts at adverse
conditions by increasing the
compressor starting torque.
Compressor Control Module:
Built-in off-delay timer adjustable
from 30 seconds to 5 minutes. 2-
minute on-delay if power interrupt.
120-second bypass for low pressure
control, and both soft and manual
lockouts for high and low pressure
controls. Alarm output for alarm
relay.
Liquid Line Filter Drier:
Standard on all units. Protects
system against moisture.
High & Low Pressure Switches are
Auto-Reset:
Standard on all units. Built-in lock-
out circuit resets from the room
thermostat. Provides commercial
quality protection to the compressor.

REEN EFRIGERANT
R-410A
Crankcase Heaters:
Factory installed crankcase heaters
are standard on all models. This
helps to insure ease of start at low
temperatures and improves
compressor life.
Phase Rotation Monitor:
Standard on all 3 phase scroll
compressors. Protects against
reverse rotation if power supply is not
properly connected.
Galvanized 20 Gauge Zinc
Coated Steel Cabinet:
Cleaned, rinsed, sealed and dried
before the polyurethane primer is
applied. The cabinet is handsomely
finished with a baked on textured
enamel, which allows it to withstand
1000 hours of salt spray tests per
ASTM B117-03.
Galvanized 16 Gauge Zinc
Coated Unit Base:
The unit base is treated with the
same paint coatings as the cabinet
above, insuring years of service
without visible corrosion.
Drain Pan:
The evaporator drain pan is
constructed of stainless steel
material for maximum corrosion
resistance.
Electrical Components:
Are easily accessible for routine
inspection and maintenance through
a right side, service panel opening.
Features a lockable, hinged access
cover to the circuit breaker or toggle
disconnect switch.
Electric Heat Strips:
Features line break automatic limit
and dual backup safety controls.
Heater packages can be factory or
field installed for all models.
Filter Service Door:
Separate service door provides easy
access for filter change.
Two-Inch, Pleated Disposable
Air Filters:
Are standard equipment.
Condenser Fan and Motor
Shroud Assembly:
Slides out for easy access.
Circuit Breakers/Rotary
Disconnect:
Standard on all versions of single (230/
208 volt) and three phase (230/208
volt) equipment. Rotary disconnects
are standard on all versions of three
phase (460 volt) equipment.
Slope Top:
Standard feature for water run-off.
Full Length Mounting Brackets:
Built into cabinet for improved
appearance and easy installation.
NOTE: Bottom mounting bracket
included to assist in installation.
Top Rain Flashing:
Standard feature on all models.
