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.

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.

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.

 Engineered Features

THE WALL-MOUNT™ STEP CAPACITY AIR CONDITIONERS

Integrated Part Load Value (IPLV) Efficiency Up To 15.3 BTU/WATT

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.
