The Bard Wall-Mount Electric Air Conditioner with gas fired heating 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, portable structures, correctional facilities, retail stores or other
commercial applications. Factory or field installed accessories are available to meet specific job requirements.

• High Efficiency
• Low Sound Level
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.
Step Capacity Compressor:
Copeland step-capacity (2-stage) scroll
compressors are designed for increased
efficiency, quieter operation and improved
reliability for longer life.

1 Motor will deliver consistent CFM through voltage supply range with no deterioration (197-253V for 230/208V models, 414-506V for 460V models).
2 Continuous CFM is the total air being circulated during continuous (manual) fan mode.
3 Will occur automatically with a call for “Y1” signal from thermostat.
4 Will occur automatically with a call for “Y2” signal from thermostat.
5 Will occur automatically with a call for “W” signal from thermostat.
6 Constant CFM of Variable Speed Motor should maintain mid-rise temperature differential through range of allowable static.
Bard Wall-Mounts are designed to provide optional ventilation packages to meet all of your ventilation and indoor air quality requirements.
All units are equipped with a barometric fresh air damper as the standard ventilation package. All ventilation packages can be built-in at the
factory, or field-installed at a later date.
BLANK OFF PLATE - WGSBOP STANDARD
A blank off plate is installed on the inside of the service door. It covers the air inlet openings which restricts any outside
air from entering the unit. The blank off plate should be utilized in applications where outside air is not required to be
mixed with the conditioned air.
COMMERCIAL ROOM VENTILATOR - WGSCRVMP-5 OPTIONAL
The built-in commercial room ventilator is internally mounted behind the service door and allows outside ventilation air,
up to 50% of the total airflow rating of the unit, to be introduced through the air inlet openings. It includes a built-in
exhaust air damper with integral bug screen. Automatic control is integrated to maintain desired ventilation air at the
various supply airflows while on Stage 1, Stage 2 or ventilation modes of operation.
The commercial room ventilator (CRV) is a simple and innovative approach to improving the indoor air quality by
providing fresh air intake and exhaust capability through the CRV. The damper can be easily adjusted to control the
amount of fresh air supplied into the building. The CRV can be controlled by indoor blower operation or field controlled
based on room occupancy. The CRV is power open - spring return on power loss. Complies with ANSI/ASHRAE
Standard 62.1 “Ventilation for Acceptable Indoor Air Quality”.
CO
2
Sensor Ready: • WGSCRVMP-5 is designed for CO
2
based on ventilation control
by simply wiring in a field installed CO
2
sensor if desired.
ECONOMIZER - WGSEIFM-5 OPTIONAL
The built-in economizer system is internally mounted behind the service door and allows outdoor air to be introduced
through the air inlet openings. The amount of outdoor air varies in response to the system controls and settings defined
by the end user. It includes a built-in exhaust air damper. The economizer is designed to provide “free cooling” when
outside air conditions are cool and dry enough to satisfy cooling requirements without running the compressor. This in
turn provides lower operating costs, while extending the life of the compressor.
Standard Features:
• One Piece Construction - Easy to install with no mechanical linkage adjustment required.
• Exhaust Air Damper - Built in with positive closed position. Provides exhaust air capability to prevent
pressurization of tight buildings.
• Actuator Motor - 24 volt, power open, spring return with built in torque limiting switch.
• Proportioning Type Control - for maximum “free cooling” economy and comfort.
• Moisture Eliminator & Prefilter - permanent, washable aluminum construction.
• Enthalpy Control - adjustable to monitor outdoor temperature and humidity.
• Minimum Position Potentiometer - adjustable to control minimum damper blade position for ventilation purposes.
• Mixed Air Sensor - to monitor outside and return air to automatically modulate damper position.
WALL-MOUNT ENERGY RECOVERY VENTILATOR - WGSERV-5 OPTIONAL
The wall-mount energy recovery ventilator (WGSERV-5) is a highly innovative approach to address indoor air quality ventilation
requirements as established by ANSI/ASHRAE Standard 62.1. The WGSERV-5 allows up to 450 CFM (depending upon
speed setting) of fresh air and exhaust through the unit while maintaining superior indoor comfort and humidity levels. In most
cases this can be accomplished without increasing equipment sizing or operating costs. Heat transfer efficiency is up to 74%
during summer and 80% during winter conditions.
The WGSERV-5 consists of a unique “rotary energy recovery cassette” that provides effective sensible and latent heat
transfer capabilities during summer and winter conditions. Various control schemes are addressed including limiting ventilation
during building occupancy only.
The WGSERV-5 is designed to be internally mounted behind the service door in the WGS Gas/Electric units. It can be built-
in at the factory or field installed as an option. WGSERV-5 can be independently adjusted for intake and exhaust rates.
Manufactured under U.S. Patent Nos. 5,301,744; 5,485,878

Heating input, and thus heating output, decreases with altitude. No orifice change is required up to 6,000 feet elevation and derate occurs naturally due
to altitude impact. Natural gas models may require orifice change based on BTU content of gas. See Natural Gas Orifice and Altitude Tables on
next page for details. For Propane Gas see the Propane Gas Conversion Table below.
All orifice sizes shown are millimeters (mm).
Above 6,000 feet elevation orifice changes are required, and capacity reductions are a function of altitude impact and orifice change. Pressure switch
change is required above 6,000 feet elevation. For Natural Gas see the Orifice and Altitude Tables on next page. For Propane Gas see the Propane
Gas Conversion Table below.

WARNING
A minimum of one (1) inch clearance must be maintained between the supply air duct and combustible materials. This is
required for the first three (3) feet of ducting.
It is important to insure that the one (1) inch minimum spacing is maintained at all points.
Failure to do this could result in overheating the combustible material and may result in a fire causing damage, injury or death.

Air Conditioning Wall-Mount Model Nomenclature
STD = Standard equipment for these specified models.
1 HPC. High pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note 3.
2 LPC. Low pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note 3.
3 CCM. Compressor control module has adjustable 30-second to 5-minute delay-on-break timer. On initial power-up, or any time the power is interrupted, the delay-on-make will be
2-minutes plus 10% of the delay-on-break setting. There is no delay-on-make during routine operation of the unit. The module also provides the lockout feature (with 1
retry) for high and/or low-pressure controls, and a 2-minute timed bypass for low-pressure control.
4 LAC. Low ambient control permits cooling operation down to 0°F.
5 SK. Start capacitor and potential relay start kit can be used with all -A single phase models. Increases starting torque 9x. Not used for -B or -C three phase models.
