Multi-Capacity Two-Stage:

Simple thermostatic control

seamlessly stages the compressor

and indoor airow rate between

high and low capacity operations

without cycling the compressor. This

helps to maximize comfort, humidity

control, energy efciency and overall

reduction in compressor cycling for

improved system life.

Multi-Step Capacity Compressor:

Copeland step-capacity scroll

compressors are designed for

increased efciency, 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 efciency,

low sound levels and soft-start

capabilities.

The motor is self-

adjusting to provide the proper airow

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 n for maximum heat

transfer and energy efciency.

The Bard WA/L “S” Series is the world’s most energy efcient 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 efcient

system, which is designed to offer maximum indoor comfort at a minimal

cost without using valuable indoor oor space or outside ground space. This

unit is the ideal product for versatile applications such as: new construction,

modular ofces, school modernization, telecommunication structures, portable

structures or correctional facilities. Factory or eld installed accessories are

available to meet specic job requirements.

Twin Blowers:

Move air quietly. All models feature

variable speed blower motors

providing automatic airow 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 Coefcient

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) Efciency 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

nished 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

eld installed for all models.

Filter Service Door:

Separate service door provides easy

access for lter 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.
