3 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. BAROMETRIC FRESH AIR DAMPER STANDARD The barometric fresh air damper is a standard feature on all models. It is installed on the inside of the service door 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 damper opens during blower operation and closes when the blower is off. Adjustable blade stops allow different amounts of outside air to be introduced into the building and can be easily locked closed if required. MIS-34 Barometric Fresh Air Damper BLANK OFF PLATE OPTIONAL 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 OPTIONAL The motorized fresh air damper is internally mounted behind the service door 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 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. NOTE: The above vent systems are intake only without built-in exhaust capability. Building will likely require separate field installed barometric relief or mechanical exhaust elsewhere within the conditioned space. Balancing dampers in the return air grille may be required to achieve specified amount of outdoor air intake. Motorized Fresh Air Damper MIS-35 COMMERCIAL ROOM VENTILATOR OPTIONAL The built-in commercial room ventilator is internally mounted behind the service door and allows intake of outside ventilation air. It includes a built-in exhaust air damper for room pressurization relief. 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. Complies with ANSI/ASHRAE Standard 2. for Acceptable Indoor Air Quality. Standard Features: Fully modulating Honeywell Hi-Torque Actuator with -V signal input capability No hood required Simple single blade design Positive shut-off with non-stick gaskets Solid State Controller with occupancy CFM setting and modulating 4-2 ma thermostat signal input Commercial Room Ventilator Economizer Energy Recovery Ventilator MIS-3 MIS-3 MIS-37 ECONOMIZER OPTIONAL The built-in economizer is internally mounted behind the service door and allows outside ventilation air, up to % of the total airflow rating of the unit. It includes a built-in exhaust air damper for room pressurization relief. 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: Full rated outdoor intake Fully modulating Honeywell Hi-Torque Actuator 7" intake hood with filter 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 OPTIONAL The wall-mount energy recovery ventilator () is a highly innovative approach to meeting indoor air quality ventilation requirements as established by ANSI/ASHRAE Standard 2.. The allows from 2 to 45 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. Intake and exhausted blowers have 3 independently selectable speeds. The 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 is designed to be internally mounted behind the service door in the W**AA or W**LA model wall-mount units. It can be built-in at the factory (W**A only) or field installed as an option. WP-*3 and WP-*5 can be independently adjusted for intake and exhaust rates. The s have exhaust gravity shut-off dampers and motorized air intake dampers for positive shut-off. Wiring includes plug-in harnesses for easy vent installation and removal. Form No. S33-4 Supersedes S33-3 Page 3 of 2

26 Color and Cabinet Options Standard Exterior Painted Steel Finishes Exterior cabinets of standard Bard HVAC products are constructed with,, or 2 gauge zinc coated steel that is cleaned, rinsed, sealed and dried prior to a polyurethane primer being applied, followed by a baked on textured enamel. This coating system has been tested to hours exposure time per ASTM B 7-3 testing standards. Exterior cabinet screws and fasteners use a Magni 55 coating system. Parts coated to this specification are capable of withstanding neutral salt spray testing for a minimum of hours with no red rust per ASTM B 7-3 testing standards. Optional Aluminum Exterior Finish Aluminum exterior finish cabinets are available for most unit models. The exterior sides, door panels, and service access doors are of a stucco textured Aluminum 33 H4 material with excellent corrosion resistance. Exterior cabinet screws and fasteners use a Magni 55 coating system. Parts coated to this specification are capable of withstanding neutral salt spray testing for a minimum of hours with no red rust per ASTM B 7-3 testing standards. Optional Stainless Steel Exterior Finish Exterior Stainless Steel finish cabinets are often selected for corrosion and chemical resistance. Higher grades of stainless steel are often specified to meet the requirements of harsh environments. Units may not only be exposed to windblown dust, dirt, lint, and fibers but also may be exposed to corrosive agents. The Bard stainless steel grade enclosure and fasteners for years of operation in these conditions. Features - Sides, doors, grilles, back panels, and top are 3 grade stainless steel. - Base, condenser partition, and fan shroud are 34 grade stainless steel. - Stainless steel exterior cabinet screws, washers, nuts, and bolts are used. - Stainless steel outdoor motor mount and motor mount hardware. - Compressor mounting hardware is stainless steel and hex no-spin rivet nuts are used in the unit base. - Corrosion resistant coating is applied to fan blade.
