Customize to suit your needs Select from a wide variety of features, factory-supplied options and accessories to build the ideal system for your application and help reduce labor and installation costs. See "Accessories - Options" on page 17 to 23 for details on options and accessories. Quiet Operation The GentleFlo cross-tangential fan wheel design of Applied PTAC/PTHP units provides whisper quiet operation while delivering maximum airflow required for proper air circulation. Separate indoor and outdoor fan motors further reduce operating sound levels and costs. McQuay Applied Packaged Terminal Air Conditioners and Heat Pumps (Applied PTAC/PTHP) are manufactured to institutional quality standards at our ISO 9002 certified manufacturing facility. Strict attention to manufacturing details from raw materials to the unit packaging gives you a quality product, delivered on-time to support your construction schedule. Every unit is ETL Listed, MEA agency approved, ARI certified for performance and exceeds ASHRAE 90.1 efficiency requirements. The heavy gauge construction of the chassis and cabinet minimizes vibration for quieter operation. Vibration isolators on the rotary compressor keep it running smoothly and quietly. The unit bulkhead is fully insulated to decrease outdoor sound transmission. The high design standards and heavy-duty construction of the McQuay Applied PTAC/PTHP can provide you with years of reliable service, quieter operation and low operating costs. In fact, many of our comfort conditioners have been operating for more than 30 years. The Hydronic Experts McQuay is a leading manufacturer of hydronic heat equipment.

4 Beyond Standard Expectations Energy efficient for low operating costs Applied PTAC/PTHP units are built with quality components and exceed industry standards for energy efficiency for both new construction and replacement applications. This helps lower your utility costs by keeping energy consumption down and may allow you to qualify for electrical power company rebates. Unit performance is ARI certified with an Energy Efficiency Ratio (EER) up to 12.1 EER and a heat pump Coefficient of Performance (COP) up to 3.6. Built-in energy management logic comes standard with the unit s digital controls. Features such as the Sleep Function allow users to decrease the set temperature at night and during unoccupied periods to conserve energy. For heat pump applications, electric heat comes on only when the outdoor temperature is below 35 F, maximizing the amount of time the unit operates in the more efficient heat pump mode. *Consult your utility provider for rebate opportunities. Expect more than Replacement or New Construction efficiency 14% Efficiency Improvement Room Comfort * ASHRAE 90.1 Replacement Requirement 8.9 Easy to use digital controls The unit control pad offers digital readout and is easy to use when selecting fan speed, mode of operation and temperature setting. A precise digital temperature display provides guests with an exact comfort setting, thereby eliminating uncomfortable temperature swings and costly overheating/overcooling associated with non-digital electromechanical controls. Original Model * Based on original model PMES size 230 V 11.2 New Applied PDAC/PDHP - Size 012 Standard digital touchpad control Dehumidification The cool/dry mode automatically controls humidity by extending the cool cycle without sacrificing comfort for dehumidification. This mode comes standard with all units. The desired cooling mode (cool/dry for added dehumidification or regular cool) can be selected and locked by the owner or facility manager to meet comfort and dehumidification requirements. Constant room temperature monitoring Units are designed to automatically sample the room temperature and adjust operation to meet desired temperature set points. Built-in Reliability & Durable Construction High-grade cabinetry Applied PTAC/PTHP cabinets are constructed of 18-gauge steel with baked on powder coat paint for maximum durability and aesthetic appeal. Grilles have two-way adjustment allowing air to be directed where it is needed. Positive condensate removal Our unique three level sloped basepan design provides positive condensate removal to prevent condensate build-up or overflow. Positive condensate removal Page 4 of 32 / Catalog 1355

5 Beyond Standard Expectations Room freeze protection When the unit senses temperatures of 40 F or lower in an unoccupied room, the heat mode is automatically initiated to prevent freezing. The outdoor fan and compressor are stopped to help prevent coil freeze. Electric heat override Heat pump units can be manually switched to electric heat, providing added freeze protection if the heat pump mode is not available due to a compressor failure. Compressor protection The life of the compressor is extended through built in protection logic such as: High temperature protection if the compressor temperature exceeds 154 F Minimum run time Minimum off time Random restart after a power outage Low ambient lockout when the outdoor air temperature falls below 35 F Memory recall Control settings are saved in a non-volatile memory, allowing the last settings to be recalled after a loss of power. Seacoast construction Application of air conditioning equipment in a corrosive environment requires special consideration. The corrosive nature of salt water vapor, chlorine and acid vapor, demands a unit that can withstand these environments. Any metal portion that is exposed to a corrosive vapor must be specially treated. There is no coating or treatment that will allow a unit to last indefinitely, however, the Applied PTAC is available with parts that receive special corrosion protection that can help dramatically extend the life of the unit. Wall Sleeve The entire Custom Wall Sleeve (CWS) or cabinet/wall sleeve is constructed of G-60 galvanized, phosphatized, 18-gauge steel. Treated inside and outside with a baked-on epoxy based powder coat paint to protect it from the corrosive effects of salt spray. The Basic Wall Sleeve (BWS) is constructed of galvanized, primed and pre-painted antique ivory 18-gauge steel. Base Pan Protected with Casing Guard coating, providing a comprehensive corrosion protection for all exposure conditions. Condenser Coil Protected with E-Coating, made up of an epoxy primer and acrylic top coat that is electrostatically applied and baked on. Also, there is a dielectric strip located between the condenser and base pan. Condenser Fan Blade and Slinger Ring Constructed of Noryl PPO which is a strong engineering plastic that has excellent flame resistance and dimensional stability over a wide range of service temperatures. Noryl has low moisture absorption, excellent strength and stiffness. Condenser Fan Motor Specially coated by the manufacturer with zinc end plates. Compressor Protective coating applied by the manufacturer on the exterior to enhance equipment life and performance. Outdoor Louver Made of aluminum, etched and anodized for maximum corrosion protection. Available in stamped or architectural styles. Easy Installation and Service Design Quick link connections Applied PTAC/PTHP units are designed for easy access with quick link connections to the control box. The simple slide in/slide out configuration makes it easy to access the electric heater, indoor and outdoor fans, motors, and compressor. Easy fan removal Easy fan motor removal Easy to read LED diagnostics Sensors in the unit continually monitor the indoor coil, outdoor coil, and outdoor air conditions. If abnormal conditions are detected, an error code is displayed, removing the guess work in troubleshooting a unit. Catalog 1355 / Page 5 of 32

13 Application Considerations How to Select The Correct Wall Cabinet The minimum cabinet depth is 10.75". This is required because the wall sleeve MUST extend a minimum of 1.625" into the room and 9.125" is required to cover the chassis. This totals 10.75". Standard cabinets range from 10.75" to 18.75" in 1" increments. For other requirements, consult the factory. If the wall sleeve extends into the room more than 1.625", add the inside measurement to the 9.125" required to cover the chassis. This will be the depth of the wall cabinet. For example: The wall sleeve extends 3.25" into room " = 12.75" deep cabinet or if the wall sleeve extends 9.25" into room " = 18.75" deep cabinet would be the closest fit. Wall Opening Requirements 16" x 42" When roughing in the opening for the wall sleeve, sufficient clearance from the walls and floor is required. The wall sleeve should be positioned a minimum of 5/8" from the finished side wall to accommodate the room cabinet. A minimum distance of 3" above the finished floor is required for return air. The rough opening should measure 16 1 /4" high x 42 1 /4" wide. When using a louver frame, the opening must measure 16 5 /8" x 42 5 /8". Louver frames should be used for panel wall and thin wall applications to provide positive anchoring to the wall. Electrical Service All wiring should be in accordance with all local and National Electrical Code requirements. Units are supplied with an attachment cord and plug which exit from the bottom of the conditioner on the control side. The cord for 115V, 208V and 230V has a usable length of 72" (1829mm) from where it exits the conditioner. The use of extension cords to increase the length of the plug/cord set is not recommended. Units to operate on 265V are supplied with a 18" (457mm) cord for connection to a subbase. The attachment plug size should be used to determine the circuit ampacity and overcurrent protection. Time delay, overcurrent protection devices are recommended to prevent unit damage and to avoid nuisance tripping. Receptacles are generally located beneath the conditioner, on or recessed in the wall so it is concealed by the conditioner overhang and kickplate (see page 16).

23 Accessories Options Energy Saving Options Automatic Change over, Remote Mounted Thermostat Thermostats can be obtained to switch from heating to cooling and from cooling to heating automatically. With automatic change over, the operation of the heating cycle or the cooling cycle is determined by the temperature requirement of the space. Most thermostats with this feature are set to change over when the room temperature varies 3-1/2 o F from the set-point. The unit is placed in the cooling mode when the set-point is over 3-1/2 o F; 3-1/2 o F under the set point places the unit in the heating mode. This 3-1/2 o F variation is usually adjustable from a 1/2 o F dead band to a 5 o F dead band. Each cycle is run until the set point temperature is reached, then that cycle is de-energized. On some thermostats, the automatic change over function can be overridden manually by moving the thermostat selector switch to heat or to cool. The fan operation, with an automatic change over thermostat, is controlled by the fan selector switch. When placed in the fan mode, the fan runs continuously. When placed in the auto mode, the fan will only energize when the thermostat calls for heating or cooling. Program Setback Control With the Programmable Touchpad, four (4) different periods, Morn., Day, Eve., or Nite, can be independently programmed for start time, Heat setting and Cool setting. There are additional energy savings with Programmed Setback Control. Fresh Air Dampers McQuay Packaged Terminal conditioners can be furnished with an automatic fresh air damper in lieu of a manual fresh air damper. The automatic damper is wired in parallel to the indoor fan relay. In the Set-up menu on the touchpad, with the damper set to AU (Automatic) and the OAS (Outdoor Air Sensor) is > (greater than) 40º F but is < (less than) 90º F and the IAS (Indoor Air Sensor) is > (greater than) 50º F and if the unit is placed in the cycle mode, the fan and damper cycle as the thermostat cycles. If the unit is placed in the constant mode, the fan runs continuously and the damper is always open subject to the sensors. The automatic damper feature can be overridden in the Set-up menu by placing the automatic damper setting in the CL (Closed) position. In this position, the damper remains closed during all cycles of the unit. Special Paint The Standard paint on the NYC Style unit is Antique Ivory with a contrasting Oxford Brown subbase. This color combination blends well with the most interior color schemes. A durable electrostatically applied, baked on, antique ivory urethane powder paint is used that resists smudges and corrosion. Each steel component is painted separately and oven baked for durability. Catalog 1355 / Page 23 of 32

27 Engineering Guide Specifications 16" x 42" Model PDAC/PDHP with Top-Mounted Hydronic Heat Furnish and install where shown on plans packaged terminal air conditioners of the sizes and capacities shown on the schedule. The units shall be located as shown on the drawings and shall include cabinet/wall sleeve, chassis, outdoor louver, hydronic heat section, valve, and room cabinet. All units shall be ETL. listed for safety and ARI certified for performance. Overall dimensions for the basic unit shall not exceed 52" wide, 22-1/2" high, and 17-3/4" deep. Overall dimensions of the wall sleeve shall be 16" high, 42" wide and (13-3/4"/ ) deep. All units shall operate on volts, 60 Hz, 1 phase power. (Units furnished with hydronic heat shall not exceed 43" wide, 241/2" high and 20" deep). The minimum energy efficiency ratio (EER) in BTU per hour per watt for each (PDAC) (PDHP) unit must be in compliance with ASHRAE 90.1 replacement or new construction criteria, for all sizes. The minimum COP for heat pumps, at 47oF DB outdoor, must be 2.9 for all sizes. Heating/Cooling chassis Chassis shall be slide-in, plug-in type with a self-contained, hermetically sealed refrigerant circuit. All chassis sheet metal parts shall be constructed of either powder-coated A-60 or G-60 galvanized steel for maximum corrosion resistance. The chassis shall consist of the following components: Vibration isolated compressor; rifled copper tubed evaporator and condenser coils with high efficiency raised lance aluminum plate fins mechanically expanded to the tubes for maximum heat transfer; and a capillary restrictor type refrigerant metering device. Coils shall be factory tested at 300 psig. (Heat pump models shall also include reversing valve and charge balancing device). A positive closing (manual) fresh air damper may be located within the chassis to provide fresh air during fan operation. Airflow system shall include separate fan motors for the condenser and evaporator sections. The condenser fan motor shall be a single-speed, totally enclosed, permanently lubricated fan motor. Condenser fan shall be propeller-type with a slinger ring and shall be constructed of aluminum. The indoor fan motor shall be a two-speed, totally enclosed; permanently lubricated fan motor must be positioned on the indoor side of the bulkhead so as to be completely within the conditioned, filtered airstream. The indoor blower fan shall be a forward-curved tangential design to provide even airflow across the evaporator coil. During the cooling cycle: The compressor, the outdoor fan motor and the indoor fan motor shall be energized. Condensation accumulated on the evaporator coil shall be drained into the outdoor section where it is to be picked up by the condenser fan/slinger ring and evaporated against the outdoor coil. In the cool mode, the compressor will cut in if the space temperature is at least 1 F above the thermostat set point and will cut out when the space temperature is approximately 2 F below set point, subject to timing protections. During the heating cycle: Electric Resistance Heat Control will call for electric heat when the space temperature is 1 F lower that the set point. The control will cease its call when the space temperature is 3 F or higher than set point. Only the indoor fan motor and electric resistance heater are energized. The outdoor condenser fan motor and compressor shall not be energized. Heater shall be open wire type with quick response and high limit cutout. Heaters shall be sized to meet heating requirements as shown on the schedule. Electric resistance heaters must be placed behind the indoor evaporator coil and must not be visible through the indoor discharge grille. When the heater cuts out the indoor fan continues to run for 15 seconds at the set speed, regardless of On or Off mode. After 15 seconds the fan will stop running if unit is in Off mode, else the fan operation will depend on Fan Continuous or Fan Cycle setting. Hydronic, Hot water or Steam, heat Only the indoor fan motor, the (normally open) (normally closed) valve and automatic fresh air damper shall be energized. The outdoor condenser fan motor and compressor shall not be energized. Hydronic Heat When the control is in the heat mode and calling for heat, the indoor fan shall not turn on until the HFLO sensor is above 115 F. If at any time while the unit is in heat mode the HFLO sensor is below 95 F, the indoor fan shall turn off immediately. Control will check if the HFLO sensor temperature is above 115 F for 2 seconds before resuming indoor fan operation. Hydronic with Intermediate Electric heat Upon the call for heating and thereafter the HFLO sensor temperature will be monitored. A trend in HFLO sensor Temperature shall determine which form of heat is to be used. If during the 90 seconds that Hydronic is the heat source and the HFLO sensor is above 105 F and is increasing at 2 F per minute then Hydronic is the heat source. If during this 90 seconds, the temperature of the HFLO sensor is above 105 F and is not increasing at 2 F per minute then Electric is the heat source. The hydronic valve is opened for 90 seconds. After 90 seconds whether Hydronic or Electric provides the heating is determined by the following: If HFLO sensor temperature is less that 105 F, Electric provides the heat. If HFLO sensor temperature is greater than 115 F, Hydronic provides the heat Catalog 1355 / Page 27 of 32
