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-4A Refrigerant: Designed with R-4A (HFC) non-ozone depleting refrigerant in compliance with the Montreal protocol and 2 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 selfadjusting 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. 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: 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.

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 blank off plate 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 - BOP 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. MOTORIZED FRESH AIR DAMPER - MFAD OPTIONAL The motorized fresh air damper is internally mounted behind the service door and allows outside ventilation air, up to 25% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be mixed with the conditioned air. The two position damper can be fully open or closed. The damper blade is powered open by a 24VAC motor with spring return on power loss. The damper can be controlled by indoor blower operation or can be field connected to be managed based on building occupancy. Motorized Fresh Air Damper MIS-35 NOTE: This vent system is intake only without built-in exhaust capability. Building will likely require separate field installed barometric relief or mechanical exhaust elsewhere within the conditioned space. Other building systems will govern actual amount of intake air. Commercial Room Ventilator Economizer Energy Recovery Ventilator MIS-3 MIS-3 MIS-37 COMMERCIAL ROOM VENTILATOR - CRVMP OPTIONAL The built-in commercial room ventilator is internally mounted behind the service door and allows outside ventilation air, up to 5% 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. 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 2. Ventilation for Acceptable Indoor Air Quality. ECONOMIZER - ECONWM-Series 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. ECONWMT Equipment Building versions have extended air intake hood to deliver up to % of cooling rated airflow. ECONWMS versions have 3 air intake hood to deliver up to % of cooling rated airflow. Features: Fully modulating Honeywell Direct Drive Hi-Torque Actuator No linkage required Simple single blade design Positive shut-off with non-stick gaskets Electronic DB and/or Enthalpy sensors depending upon version Honeywell JADE electronic economizer module with precision settings and diagnostics DB or Enthalpy economizer versions available WALL-MOUNT ENERGY RECOVERY VENTILATOR - ERVF OPTIONAL The wall-mount energy recovery ventilator (ERV) is a highly innovative approach to meeting indoor air quality ventilation requirements as established by ANSI/ASHRAE 2.. The ERV allows from 2 to CFM (depending upon model) 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 7% during summer and % during winter conditions. The ERV 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 ERV is designed to be internally mounted behind the service door in the WA/LS model wall-mount units. It can be built-in at the factory or field installed as an option. ERVF-*5 can be independently adjusted for intake and exhaust rates. Form No. S337-27 Supersedes S337-77 Page 3 of 2

HPC. High pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note. LPC. Low pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note. CCM. Compressor control module has adjustable 3-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 % 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 retry) for high and/or low-pressure controls, and a 2-minute timed bypass for low-pressure control. LAC. Low ambient control permits cooling operation down to F. ALR. The alarm relay has a set of normally open and normally closed dry contacts to provide the ability to signal a condition of shutdown on either high or low pressure controls. SK. Start kit standard on all -A single phase models only. Is not used or available for -B or -C three phase models. DDC. Incorporates 4 additional sensors: discharge air temperature, indoor blower airflow, compressor current, and dirty filter. These sensing devices function to input analog data such as temperature, as well as digital data such as airflow, compressor status or filter status.
