3 Ventilation System Packages Bard Wall-Mounts are designed to provide optional ventilation packages to meet all of your ventilation and indo 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 facty, fieldinstalled at a later date. BLANK OFF PLATE - BOP STANDARD A blank off plate is installed on the inside of the service do. 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. Motized Fresh Air Damper MOTORIZED FRESH AIR DAMPER - MFAD OPTIONAL The motized fresh air damper is internally mounted behind the service do and allows outside ventilation air, up to % 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 closed. The damper blade is powered open by a 4VAC mot with spring return on power loss. The damper can be controlled by indo blower operation can be field connected to be managed based on building occupancy. NOTE: This vent system is intake only without built-in exhaust capability. Building will likely require separate field installed barometric relief mechanical exhaust elsewhere within the conditioned space. Other building systems will govern actual amount of intake air. COMMERCIAL ROOM VENTILATOR - CRVMP OPTIONAL The built-in commercial room ventilat is internally mounted behind the service do and allows outside ventilation air, up to % 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. COMMERCIAL ROOM VENTILATOR The commercial room ventilat (CRV) is a simple and innovative approach to improving the indo 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 indo blower operation field controlled based on room occupancy. The CRV is power open - spring return on power loss. Complies with ANSI/ASHRAE. Ventilation f Acceptable Indo Air Quality. ECONOMIZER - EIFM OPTIONAL The built-in economizer system is internally mounted behind the service do and allows outdo air to be introduced through the air inlet openings. The amount of outdo air varies in response to the system controls and settings defined by the end user. It includes a built-in exhaust air damper with integral bug screen. The economizer is designed to provide free cooling when outside air conditions are cool and dry enough to satisfy cooling requirements without running the compress. This in turn provides lower operating costs, while extending the life of the compress. ECONOMIZER Unit shown with optional Economizer 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. Actuat Mot - 4 volt, power open, spring return with built in tque limiting switch. Proptioning Type Control - f maximum free cooling economy and comft. Moisture Eliminat & Prefilter - permanent, washable aluminum construction. Enthalpy Control - adjustable to monit outdo temperature and humidity. Minimum Position Potentiometer - adjustable to control minimum damper blade position f ventilation purposes. Mixed Air Sens - to monit outside and return air to automatically modulate damper position. WALL-MOUNT ENERGY RECOVERY VENTILATOR - ERVF OPTIONAL The wall-mount energy recovery ventilat (ERV) is a highly innovative approach to meeting indo air quality ventilation requirements as established by ANSI/ASHRAE.. The ERV allows from to 4 CFM (depending upon model) of fresh air and exhaust through the unit while maintaining superi indo comft and humidity levels. In most cases this can be accomplished without increasing equipment sizing operating costs. Heat transfer efficiency is up to 7% during summer and 7% 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. ENERGY RECOVERY VENTILATOR The ERV is designed to be internally mounted behind the service do in the WA/LS model wall-mount units. It can be built-in at the facty field installed as an option. ERVF-* can be independently adjusted f intake and exhaust rates. Manufactured under U.S. Patent Nos.,4,7;,,744. Fm No. S7- Supersedes S7- Page of
