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, efcient 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.

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 airow 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 certied 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 certied
for performance and exceeds ASHRAE 90.1 efciency
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 congurable 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 efcient for low operating costs
Applied PTAC/PTHP units are ARI Certied and
built with quality components and exceed industry standards for energy efciency 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
efcient heat pump mode.
*Consult your utility provider for rebate opportunities.
Non-Ozone Depleting
R-410A Refrigerant
Standard digital touchpad control
Dehumidication
The cool/dry mode automatically controls humidity
by extending the cool cycle without sacricing comfort
for dehumidication. This mode comes standard with
all units. The desired cooling mode (cool/dry for added
dehumidication or regular cool) can be selected and
locked by the owner or facility manager to meet comfort
and dehumidication 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 overow.

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 indenitely, 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 conguration makes it easy
to access the electric heater, indoor and outdoor fans,
motors, and compressor.
Easy fan 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.
