1 I-TEC I30AD-IAD 2-Stage Compressor High Efficiency Air Source Air Conditioners w/dehumidification Cooling Capacities: 20,0 to 54,000 Btuh The Bard I-TEC Air Conditioner system is designed for classrooms and other similar applications demanding high efficiency and the lowest possible sound levels that are practical and achievable, and also accommodates the over-the-window sill requirement for many replacement projects on older school buildings. The I-TEC Series meets that challenge with many innovative design features resulting in a highly refined appearance while at the same time improving on the very important maintenance and serviceability features needed by the facilities maintenance and service staffs. I-TEC Standard Features All models have dehumidification (hot gas reheat) Double wall construction, 20-ga. exterior skin, no visible fasteners No fiberglass insulation Hinged, lockable, removable doors Removable sides and modularized construction for transporting through standard doors or in elevators allows installation on second and third floor Can be installed in left or right corners with no modifications Non-corrosive drainpans with no standing water 2-Stage scroll compressors with discharge muffler, double floating isolation mounting system, and sound muffling cover for ultra quiet operation R-4A Green Refrigerant Cooling thermostatic expansion valves Extra large full width control panel for easy access to all controls Circuit Breakers on 230V models, and Toggle Disconnect on 4V Evaporator coils constructed with hydrophilic fin stock with the following advantages: Acrylic coating Wettable surface with low contact angle no bead-up condensate, lower wet-coil air-side pressure drop, improved draining & lower re-entrainment of moisture back into the air stream in continuous blower operating modes Antimicrobial properties provide microbial resistance to fungicidal growth Resistant to Mold and Mildew, ASTM D3273 no growth Seals fin surface against aluminum oxide formation 24VAC 75VA control transformer with circuit breaker 24VAC low-voltage terminal strip for thermostat or DDC control ECM indoor and outdoor motors Modulating outdoor fan motor and low ambient control Modulating indoor fan motor for constant CFM in different operating modes up to 0.50" ESP High and Low Pressure switches with lockout circuit Liquid line filter/drier Readily accessible service ports located behind locking hinged doors Pleated 2" MERV filter Designed for over-the-window sill wall penetration and has 3" vertical adjustment for wall sleeve attachment I-TEC Optional Features & Accessories Four Ventilation Options: Both ERV and CRV have ECM motors, filter system, and positive shut-off. Energy Recovery Ventilator (ERV) is designed for both modulating or fixed supply and exhaust airflow operation depending upon environmental controls used, and has positive shutoff on intake and exhaust sides when unoccupied. Modulating mode requires CO 2 controller, has intake rate that is higher than exhaust, and has optional minimum CFM to address building IAQ requirements. The system modulates to maintain selected maximum CO 2 level. Fixed mode can be used with thermostat or DDC that has a dedicated Occupied output that is ON during Occupied and OFF during Unoccupied. Intake and exhaust rates can be independently adjusted. Commercial Room Ventilator (CRV Option M) is a fan powered ventilation package to manage intake & exhaust air at fixed rates but without energy recovery capability. The rates are: CFM, are independently selectable & has positive shutoff on intake and exhaust sides when unoccupied. Requires control system that has a dedicated ventilation control output to be ON during Occupied and OFF during Unoccupied. CO2 controller with ON/OFF output relay can be used. Factory setting is 375 CFM balanced to meet pressurization requirements of ASHRAE. Commercial Room Ventilator (CRV Option N) is same as CRV Option M and also has a free-cooling economizer mode that can provide up to 525 CFM when the outdoor ambient temperature is below the set point of the outdoor thermostat. Units designed to be flush to a smooth interior wall and not require trim kits by use of adjustable wall sleeves; Trim Kits available where required Low sound levels are achieved by numerous system design innovations including special acoustical insulation Installation flexibility. Can be installed in corner applications with one side against a wall. Condensate overflow detection system with diagnostics monitors equipment and shuts down compressor to prevent condensate overflow. Freezestat on indoor coil safeguards against indoor coil freeze up by shutting down the compressor. Commercial Room Ventilator (CRV Option Q) is modulating design that requires 0-Vdc control signal from CO 2 controller. Other Options: Hot water coil packages, both Duct-Free and Ducted versions available. Accessories: See Page 2 & 3. ERV MIS-374 CRV MIS-3742 Form No S Supersedes S344-7 Page of 22

7 DEHUMIDIFICATION CIRCUIT The I**A models with standard dehumidification provide a unique circuit for periods of high indoor humidity conditions. Additionally, an energy recovery ventilator may be provided to allow for outside ventilation air requirements by eliminating excessive sensible and latent loads as a result of the increased ventilation requirement. The dehumidification circuit incorporates an independent heat exchanger coil in the supply air stream in addition to the standard evaporator coil. This coil reheats the supply air after it passes over the cooling coil, and is sized to nominally match the sensible cooling capacity of the evaporator coil. Extended run times in dehumidification mode can be achieved using waste heat from the refrigeration cycle to achieve the reheat process, while at the same time large amounts of moisture can be extracted from the passing air stream. See below for specific operating sequences, and see attached tables for performance on sensible and latent capacities, water removal ratings, and supply air delivery conditions. The dehumidification refrigerant reheat circuit is controlled by a 3-way valve directing the refrigerant gas to the normal condenser during periods when standard air conditioning is required. During periods of time of low ambient temperature (approximately 5 to 75 outdoor) and high indoor humidity, a humidistat senses the need for mechanical dehumidification. It then energizes both the compressor circuit and the 3-way valve, thus directing the hot refrigerant discharge gas into a separate desuperheating condenser circuit which reheats the conditioned air before it is delivered to the room. The refrigerant gas is then routed from the desuperheating condenser to the outdoor coils for further heat transfer. When the humidistat is satisfied, the system automatically switches back to normal A/C mode and either continues to operate or turns off based on the signal from the wall thermostat. The result is separate humidity control at minimum operating cost. DEHUMIDIFICATION SEQUENCE OF OPERATION Dehumidification is controlled through a humidistat and is independent of the thermostat. On a call for dehumidification mode of operation, the compressor will operate at full load (capacity) and 3-way valve that feeds the reheat coil is energized through D terminal. Dehumidification will continue until the humidistat is satisfied. Anytime there is a R-Y call for cooling, dehumidification is canceled and the unit will operate in the cooling mode at part load for Stage cooling (can shift to full load if 2nd Stage cooling required) until satisfied. If dehumidification call is still present when cooling call is satisfied, the unit will continue to operate and revert to dehumidification mode with compressor at full level.
