Introduction
In 1958, McQuay introduced the Incremental® system – the rst through-the-wall, self-contained heat­ing and air conditioning system – and set the standard for reliable, efcient comfort control in multi-story building
applications. With hundreds of thousands of installed units - many of which have been operating for more than
30 years - McQuay has earned its reputation as one of
the most trusted names in individually-zoned comfort control.
As one of the world’s largest heating, ventilation and air-conditioning manufacturers, McQuay stands behind
its products with the strength of a global organization. And with local McQuay representation and manufactur-
ing facility in Auburn, New York, we can provide you
the hands-on support you need to make your building project a success.

coming on until there is heat in the pipes.
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 18 to 24 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 airow required for proper air circulation. Separate indoor and outdoor fan
motors further reduce operating sound levels and costs.
McQuay Applied Packaged Terminal Air Condi-
tioners and Heat Pumps (Applied PTAC/PTHP) are manufactured to institutional quality standards at our ISO 9002 certied manufacturing facility. Strict atten-
tion 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 certied for performance and exceeds ASHRAE 90.1 efciency requirements.
The high design standards and heavy-duty construc-
tion 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. We specialize in providing hydronic heat with a host of congurable options.
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.

Beyond “Standard” Expectations
Energy efcient for low operating costs
Applied PTAC/PTHP units are ARI Certied and built with quality components and exceed industry stan­dards for energy efciency for both new construction and
replacement applications. This helps lower your utility costs by keeping energy consumption down and may al-
low you to qualify for electrical power company rebates.
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 coil temperature is below 28°F, maxi-
mizing the amount of time the unit operates in the more
efcient heat pump mode.
*Consult your utility provider for rebate opportunities.
Non-Ozone Depleting R-410A Refrigerant
Standard digital touchpad control
Dehumidication
The cool/dry mode automatically controls humidity by extending the cool cycle without sacricing comfort for dehumidication. This mode comes standard with all units. The desired cooling mode (cool/dry for added dehumidication or regular cool) can be selected and
locked by the owner or facility manager to meet comfort
and dehumidication requirements.
Constant room temperature monitoring
Units are designed to automatically sample the room temperature and adjust operation to meet desired tem­perature set points.
Room Comfort
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.
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 overow.

Positive condensate removal
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 and the automatic outdoor air damper will close 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 28°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 environ-
ments. 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 indenitely, however, the Applied PTAC is avail­able with parts that receive special corrosion protection that can help dramatically extend the life of the unit.
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 ame 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 conguration makes it easy to access the electric heater, indoor and outdoor fans, motors, and compressor.
Easy fan removal
Easy fan motor removal
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.
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.

Remote thermostat control
The remote thermostat can be any thermostat that
can interface with an electronic thermostat via RCBW­YG terminals. The Control Selection jumper must be in T’STAT position. During a call the remote thermostat will pass R back to the controller on a respective termi-
nal. The push buttons on the touchpad become inactive
in the remote thermostat mode. However, the control pad LED display will indicate the mode of operation, and the
room temperature.
Notes: In terms of outputs, there are two types of thermostats: relay contacts and solid state. If you open the thermostat and don’t see relays then it must be solid state. Manufacturers of solid state output thermostats include loading resistors on their installation kits. They are of 560 Ohm and 3W value. These resistors are meant to load thermostat solid state outputs in order for the output voltage to be either 0 or 24VAC, i.e. no oating voltage. These resistors are connected from W, Y, G to common (C), respectively.
You can wire any type of 24Vac thermostat straight into the REMOTE T’STAT connector of PTAC control boards, 667997101 and 667997201 (Basic and Premium models) and the control boards
will recognize the signals from them.

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 + 9.125" =
12.75" deep cabinet or if the wall sleeve extends 9.25" into room + 9.125" = 18.75" deep cabinet would be the closest t.
Wall Opening Requirements – 16" × 42"
When roughing in the opening for the wall sleeve, sufcient clearance from the walls and oor is required. The wall sleeve should be positioned a minimum of 5/8" from the nished side wall to accommodate the room cabinet. A minimum distance of 3" above the nished oor is required for return air.
The rough opening should measure 161/4" high × 421/4" wide. When using a louver frame, the opening must mea­sure 165/8" × 425/8". 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 17).

Remote Wall Mounted Thermostats
Remote Thermostat Control
The Remote Thermostat can be any thermostat that can interface with an electronic thermostat via RCBWYG terminals. The Control Selection jumper must be in T’STAT position. During a call the remote thermostat will pass R
back to the controller on a respective terminal. The push buttons on the touchpad become inactive in the remote
thermostat mode. However, the control pad LED display will indicate the mode of operation, and the room tem-
perature.
Notes: In terms of outputs, there are two types of thermostats: relay contacts and solid state. If you open the thermostat and don’t see relays then it must be solid state. Manufacturers of solid state output thermostats include loading resistors on their installation kits. They are of 560 Ohm and 3W value. These resistors are meant to load thermostat solid state outputs in order for the output voltage to be either 0 or 24VAC, i.e. no oating voltage. These resistors are connected from W, Y, G to common (C), respectively.
You can wire any type of 24Vac thermostat straight into the REMOTE T’STAT connector of PTAC control boards, 667997101 and 667997201 (Basic and Premium models) and the control boards
will recognize the signals from them.
Remote Mounted Thermostat Installation
Considerations when units are furnished with remote mounted thermostats:
1. When wiring the low voltage plug and receptacle
disconnect, provide enough wire to move harness
out of the way for chassis removal.
2. To allow Primary (Master)/Secondary (Slave)
operation, the Primary board Thermostat jumper must be in the "T-stat" position and the Secondary boards must be in the "Sec" position.
If secondary units are to be employed, see
connections in wiring illustration below. The number of secondary units that can be connected is limited to
32 units.
3. When using a programmable wall thermostat,
connect it to the terminal board remote thermostat
plug. Refer to the instructions furnished with the
chosen thermostat.

IMPORTANT
Air ow required for PTAC units must not be restricted
by exterior plants or walls. Plants or shrubs must not be planted in close proximity to the outside grille of the PTAC unit. Vegetation planted too close to grilles will cause discharge air to be recirculated, thereby increasing electrical consumption. Warranty will be voided if it is determined that the compressor life is shortened from overheating due to close proximity of outside obstructions.
Note: Discharge air restrictions include, but are not limited to:
• Vegetation
• Concrete walls or barriers
• Overhangs that do not allow discharge air to rise

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 re-
quirement of the space. Most thermostats with this feature
are set to change over when the room temperature varies
3-1/2oF from the set-point. The unit is placed in the cooling mode when the set-point is over 3-1/2oF; 3-1/2oF under the set point places the unit in the heating mode. This 3-1/2oF variation is usually adjustable from a 1/2oF dead band to
a 5oF dead band. Each cycle is run until the set point tem-
perature 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) 41º 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.

Wiring Diagrams
Digital Control Board With Standby Power
The standby power connections, L1 STBY and L2 STBY are meant to run the indoor motor at a separate voltage from the other motors, compressor and outdoor motor. When used as such, the jumpers, JH1 and JH2, must be cut. This renders L1 & L2 and L1 STBY and L2 STBY isolated from each other.
If there is no need to run the motors at a separate voltage the L1 = L1 STBY and L2 = L2 STBY. Therefore one voltage is used to run all motors.
If the jumpers are accidentally cut, then the connections can be spliced to substitute for the missing jumpers.

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 certied 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 efciency ratio (EER) in BTU per hour per watt for each PDAN unit must be in compliance with ASHRAE 90.1 replacement or new construction criteria, for all sizes using R-410A Refrigerant. The minimum COP for heat pumps, at 47°F 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; ried copper tubed evaporator and condenser coils with high efciency raised lance aluminum plate ns 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. Airow 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, ltered airstream. The indoor blower fan shall be a forward-curved tangential design to provide even airow 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

Reverse Cycle Heat Pump with back-up electric heat – The reversing valve, the compressor, the outdoor condenser fan motor and the indoor fan motor shall be energized. Reverse cycle heating shall occur when the outdoor coil temperature is 28°F and above. If outdoor coil temperature drops below 28°F or the Outdoor air temperature drops to 35°F or less, Electric heat is the only source of heat. When the Outdoor coil temperature raises back to 40°F and above, then the Compressor or Electric heater is used.
A temperature-sensing device shall be used to monitor the outdoor coil temperature to limit frost buildup. Defrosting of the outdoor
coil will be activated when outdoor coil temperature drops below 28°F or outdoor air temperature drops to 35°F or less. Defrosting is terminated when outdoor coil temperature rises back to 40°F. During defrosting, both compressor and the outdoor fan are turned
off. The indoor fan will run at its set speed.
Condensation accumulated during reverse cycle heating must NOT be evaporated against the indoor coil so as to prevent contami­nation of the indoor air with pollutants and odors. Condensation must be disposed of using a (external) (internal) drain system as
shown on plans.
Reverse Cycle Heat Pump without back-up electric heat – The reversing valve, the compressor, the outdoor condenser fan motor
and the indoor fan motor shall be energized. Reverse cycle heating shall occur when the outdoor temperatures are 35°F and above. If outdoor coil temperature drops below 28°F or the Outdoor air temperature drops to 35°F or less, the compressor stops and there is no source of heat. When the Outdoor coil temperature raises back to 40°F and above, then the compressor reverse cycle is the heat
source. A temperature-sensing device shall be used to monitor the outdoor coil temperature to limit frost buildup. Defrosting of the outdoor
coil will be activated when outdoor coil temperature drops below 28°F of outdoor air temperature drops to 35°F or less. Defrosting is terminated when outdoor coil temperature rises back to 40°F. During defrosting, both compressor and the outdoor fan are turned
off.
The indoor fan will stop if indoor coil temperature falls below 78°F. It will restart at its set speed when indoor coil temperature rises back to 80°F. Condensation accumulated during reverse cycle heating must NOT be evaporated against the indoor coil so as to prevent contami­nation of the indoor air with pollutants and odors. Condensation must be disposed of using a (external) (internal) drain system as
shown on plans.
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.
Control module – The PDAN Control module is used to control a PDAN unit that includes both an integral air conditioner and a source of heat. The Digital Control is operated with a Touchpad, IR Remote or 24 volt, Wall Mounted
Thermostat.
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.
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
