1 Q/Tec TM QASeries Air Conditioners The Q/Tec series self contained packaged air conditioner is designed to be installed inside a building structure against an exterior exposed wall. Q/Tec s design provides whisper quiet operation with total comfort for the occupants at efficiency levels up to 24% above the federal standard. This design eliminates the need for roofmounted equipment and outside condensing units and can meet your specific architectural requirements. Q/Tec s quiet technology provides extremely low sound levels (both indoor and outdoor) by using special components and materials in the construction of the unit. By using special motors, sound insulation and other sound absorbing features, we have built an air conditioner system that is significantly quieter than competitive product available today. Q/Tec is suitable for both new construction and renovation projects for schools, modular buildings and light commercial buildings. A variety of ventilation and dehumidification options are designed to address your project s indoor air quality and dehumidification requirements. The Q/Tec Series unique design allows all maintenance and service to be performed inside the building to facilitate multistory installations. Access to air filters and controls is accomplished through a hinged front panel for easy accessibility. All Q/Tec Series models are built on heavy duty permanent rollers for easy installation and removal from the wall sleeve for additional service access. Q/Tec s durable, easy to clean cabinet is aesthetically pleasing and comes standard with side and bottom trim pieces. Two types of cabinet finish are available: a durable two tone (slate and platinum) vinyl covered steel, or gray prepainted steel. Product Features Scroll Compressor The Copeland scroll compressor has been designed for increased efficiency, quieter operation with reduced shutdown noise and improved reliability for longer life.

N/ A 7 9 QA QA QA QA Note: These units are equipped with a variable speed (ECM) indoor motor that automatically adjusts itself to maintain approximately the same rate of indoor airflow in both heating and cooling, dry and wet coil conditions and at both 23/2 or 4 volts. Max. ESP (inches WC) shown is with " thick disposable filter (reduced by.2 for 2" filter) 2 Rated CFM (based on ducted application) for heating and cooling operation. To obtain full rated CFM on models QA3, QA42, QA4, and QA, refer to installation instruction supplied with unit. 3 Reduced indoor airflow option to provide lowest possible indoor air sound level. Reduces system capacity performance by approximately 2%. 4 Continuous fan CFM is the total air being circulated during continuous fan mode. 5 Indoor airflow during periods of high humidity when system is operating under control of optional humidistat for maximum humidity reduction. Model QA24 when operating on 2nd stage heating the indoor air will increase to cfm. Ventilation System Packages QTec models 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 are factory installed. BAROMETRIC FRESH AIR DAMPER STANDARD The barometric fresh air damper is a standard feature on all models. It 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. BLANK OFF PLATE OPTIONAL A blank off plate 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. NOTE: The above vent systems are intake only without builtin 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. COMMERCIAL ROOM VENTILATOR OPTIONAL The builtin commercial room ventilator is internally mounted 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 builtin exhaust air damper. 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. Ventilation for Acceptable Indoor Air Quality. Two Models Available: Spring return on power loss or deactivation Power return (will not close on power loss) ENERGY RECOVERY VENTILATOR OPTIONAL The energy recovery ventilator (ERV) is a highly innovative approach to meeting indoor air quality ventilation requirements as established by ANSI/ASHRAE Standard 2.. The ERV is internally mounted and allows up to 45 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 4% during summer and 79% 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 has a filter for the exhaust air to keep the rotary wheels clean and free of any debris introduced through the room return air grille. The intake and exhaust rates can be independently selected. Factory set on medium intake and low exhaust. ECONOMIZER OPTIONAL The builtin 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 builtin 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 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 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.
