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.

Step Capacity Compressor:

Copeland step-capacity (2-stage) 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.

Thermal Expansion Valves:

All models use TXV.

Liquid Line Filter Drier:

Protects system against moisture.

Aluminum Finned Copper Coils:

Grooved tubing and enhanced louvered fin for maximum heat transfer and energy efficiency.

High & Low Pressure Switches are Auto-Reset

Built-in lockout circuit resets from the room thermostat. Provides commercial quality protection to the compressor.

Compressor Control Module:

Standard on all units. 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.

Crankcase Heaters:

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.

Ventilation System Packages

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

ECONOMIZER

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”.

CO2 Sensor Ready: • WGSCRVMP-5 is designed for CO2 based on ventilation control by simply wiring in a field installed CO2 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.

ENERGY RECOVERY VENTILATOR	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

Important Information Concerning Altitude Impact on Heating Input Ratings

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.

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.

COMBUSTIBLE CLEARANCE	MIS-2328 D

Minimum Clearances

	Outlet Duct (from combustible materials)	1" first 3'
	Vent Terminal (from combustible materials)	17"
	Condenser Outlet	20"
	Top	See Figure 1
	Burner Service	20"
	Combustible Base (Wood or Class A, B or C	0"
	roof covering material)

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.

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.
