Important
Environmental Concerns!
Scientific research has shown that
certain man-made chemicals can
affect the earth’s naturally occurring
stratospheric ozone layer when
released to the atmosphere.
In particular, several of the identified
chemicals that may affect the ozone
layer are refrigerants that contain
Chlorine, Fluorine and Carbon (CFCs)
and those containing Hydrogen,
Chlorine, Fluorine and Carbon
(HCFCs).
Not all refrigerants containing these
compounds have the same potential
impact to the environment.
The manufacturer advocates the
responsible handling of all
refrigerants—including industry
replacements for CFCs such as
HCFCs and HFCs.
Responsible Refrigerant
Practices!
The manufacturer believes that
responsible refrigerant practices are
important to the environment, our
customers, and the air conditioning
industry.
All technicians who handle
refrigerants must be certified. The
Federal Clean Air Act (Section 608)
sets forth the requirements for
handling, recovering, recycling and
reclaiming of certain refrigerants and
the equipment that is used in these
service procedures.
In addition, some states or
municipalities may have additional
requirements that must also be
adhered to for responsible
management of refrigerants. Know
the applicable laws and follow them.
WARNIN G
Hazardous Voltage with
Capacitators!
Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure the
power can not be inadvertently
energized. Failure to disconnect
power before servicing could result
in death or serious injury.
Disconnect all electric power,
including remote disconnects and
discharge all motor start/run
capacitors before servicing. Follow
proper lockout/tagout procedures to
ensure the power cannot be
inadvertently energized. Verify with
an appropriate voltmeter that all
capacitors have discharged. Failure
to disconnect power and discharge
capacitors before servicing could
result in death or serious injury.
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to
accept other types of conductors.
Failure to use copper conductors
may result in equipment damage.

General Information
Refrigerant Handling Procedures
WARNING
Contains Refrigerant!
System contains oil and refrigerant
under high pressure. Recover
refrigerant to relieve pressure before
opening the system. See unit
nameplate for refrigerant type. Do
not use non-approved refrigerants,
refrigerant substitutes, or refrigerant
additives.
Failure to follow proper procedures
or the use of non-approved
refrigerants, refrigerant substitutes,
or refrigerant additives could result
in death or serious injury or
equipment damage.
Environmental Accountability Policy
The manufacturer urges that all
HVAC servicers make every effort to
eliminate, if possible, or vigorously
reduce the emission of CFC, HCFC,
and HFC refrigerants to the
atmosphere. Always act in a
responsible manner to conserve
refrigerants for continued usage
even when acceptable alternatives
are available.
Recover and Recycle Refrigerants
Never release refrigerant to the
atmosphere!
Always recover and/or recycle
refrigerant for reuse, reprocessing
(reclaimed), or properly dispose if
removing from equipment.
Always determine the recycle or
reclaim requirements of the
refrigerant before beginning the
recovery procedure.
Obtain a chemical analysis of the
refrigerant if necessary.
Questions about recovered
refrigerant and acceptable refrigerant
quality standards are addressed in
ARI Standard 700.
Refrigerant Handling and Safety
Consult the manufacturer’s material
safety data sheet (MSDS) for
information on refrigerant handling
to fully understand health, safety,
storage, handling, and disposal
requirements.
Use only approved containment
vessels and refer to appropriate
safety standards. Comply with all
applicable transportation standards
when shipping refrigerant
containers.
Service Equipment and Procedures
To minimize refrigerant emissions
while recovering refrigerant, use the
manufacturer’s recommended
recycling equipment per the MSDS.
Use equipment and methods which
will pull the lowest possible system
vacuum while recovering and
condensing refrigerant. Equipment
capable of pulling a vacuum of less
than 1,000 microns (1.0 mm) of
mercury is recommended.
Do not open the unit to the
atmosphere for service work until
refrigerant is fully removed/
recovered.
When leak-testing with trace
refrigerant and nitrogen, use HCFC22 (R-22) rather than CFC-12 (R-12) or
any other fully-halogenated
refrigerant.
Be aware of any new leak test
methods which may eliminate
refrigerants as a trace gas.
Perform evacuation prior to charging
with a vacuum pump capable of
pulling a vacuum of 1,000 microns
(1.0 mm) of mercury or less. Let the
unit stand for 12 hours and with the
vacuum not rising above 2,500
microns (2.6 mm) of mercury.
A rise above 2,500 microns (2.5 mm)
of mercury indicates a leak test is
required to locate and repair any
leaks. A leak test is required on any
repaired area.
Charge refrigerant into the
equipment only after equipment
does not leak or contain moisture.
Refer to proper refrigerant charge
requirements in the maintenance
section of this manual to ensure
efficient machine operation.
When charging is complete, purge or
drain charging lines into an approved
refrigerant container.
Seal all used refrigerant containers
with approved closure devices to
prevent unused refrigerant from
escaping to the atmosphere.
Take extra care to properly maintain
all service equipment directly
supporting refrigerant service work
such as gauges, hoses, vacuum
pumps, and recycling equipment.
When cleaning system components
or parts, avoid using CFC-11 (R-11) or
CFC-113 (R-113). Use only cleaningsolvents that do not have ozone
depletion factors.
Properly dispose of used materials.
Refrigeration system cleanup
methods using filters and driers are
preferred.
Check for leaks when excessive
purge operation is observed.
Keep abreast of unit enhancements,
conversion refrigerants, compatible
parts, and manufacturer’s
recommendations that will reduce
refrigerant emissions and increase
equipment operating efficiencies.

Pre-Installation
Pre-Installation
Pre-Installation Considerations
Before beginning installation, make
the following considerations:
1. Verify the wall opening is in the
correct location and the
correct size.
2. Drill mounting holes on both
sides of the wall sleeve, if
equipment requires any of the
following options: subbase,
leveling legs, or hydronic heat
kit.
If dimension A in Figure 2 is at or
near the minimum specified in
Ta b l e 2, p . 7 , accessory options
should be mounted to the sleeve
prior to installing the sleeve in
the wall. Otherwise, there may
not be enough access room for
the tools used to mount the
accessories to the wall sleeve.
3. If additional wall sleeve support
is required, the leveling leg
accessory kit or a subbase kit
that includes leveling legs can be
used to provide extra support.
4. If installing in a concrete or
masonry wall, you must provide
a lintel in the wall opening for
support. Do not use the wall
sleeve as a lintel.
See Figure 1 for a typical lintel
construction.
Figure 1. Typical Installation
framing with lintel
5. When installing in walls that are
deeper than 13 1/2 inches, use an
extended wall sleeve. A sleeve
without the proper depth will
require special care to prevent
problems with rain water,
condensate drainage, and intake/
discharge air.
Under these circumstances,
careful jobsite analysis and
cautions are required. Consult
your local HVAC representative
before attempting such
installations.

Step 7. Install the unit controls.
The PTAC controller’s normal
operation can be operated by using
either
• Display module - can be wallmounted or unit mounted.
• Remote Class 2 thermostat -
For Remote Class 2 Thermostat
Installation, read installation,
operation, and maintenance booklet
carefully.
Look in Wiring Diagram section for
information on wiring.
If a remote thermostat is connected,
the unit's display will not be present
and the controller's normal space
temperature control functionality is
overridden by the remote device.
When the controller is being directed
by a remote thermostat, the
following inputs/functions are
disabled or not present:
1. User display inputs (setpoint/
mode/fan)
2. Dehumidification
3. Configuration setup (indoor fan,
setpoint limits, EMS offset,
display units)
4. Energy management system
5. Manual Test
Unit functions that remain under
direct supervision of the controller
are:
1. Random Restart
2. Heat Pump OAT switchover
3. Tubing burst protection
4. Room freeze protection
5. Indoor coil freeze protection
6. Defrost control
When connected to a remote
thermostat, the controller interprets
the combination of thermostat inputs
as its operating mode and behaves
accordingly.
It is recommended to use a small
screwdriver to gently pryt the
removable treminal block "TB2" up
and off for easy connection.

Installation
Note: If using a third party
thermostat to control the
unit, the thermostat must
have a clearly marked OFF
state or position.
Note: It is important to make sure
that the control board’s fuse
is functioning. The specs for
the control board fuse are:
5x20mm, 250V, 315mA, fast
acting. For more inormation
on a blown fuse on the
control board, check the
Troubleshooting section of
this document.

Step 8. Configure the display module settings
Indoor Temperature setpoint
The indoor temperature setpoint
buttons tell the unit how warm or
cool the occupant wants the room.
The setpoint is set by pressinging the
up/down buttons on the interface
module. These buttons do not scroll
(i.e. holding the button will not
continue to adjust the setpoint value)
because each adjustment of the
setpoint value requires its own
unique button press.
Default setpoint on first power up:
72°F (22.0°C – closest approximation)
Setpoint resolution: ± 1°F (± 0.5°C)
User Mode Selection
Pressing the MODE button on the
unit tells the unit which mode the
occupant prefers. There are four
modes to choose from.
1. C OO L
2. HEAT
3. FAN (fan only)
4. OFF (default for first power up)
Figure 16. Digital display module
Fan Speed Selection
Pressing the FAN button on the
interface module determines fan
speed. There are two fan speeds to
choose from.
1. LOW (default for first power up)
2. HIGH
Field commissioning support
Manual Test Mode
A manual test mode is provided to
allow a field technician to verify
proper output and end device
operation through a predetermined,
timed sequence.
Fan
Mode
The sequence will automatically
advance through all outputs and exit
when the sequence has completed; it
is left to the technician to monitor the
status of the end devices during the
test to verify that each operates
properly.
Manual test is initiated by combining
the following conditions:
• User Mode = OFF
• Press and hold MODE &
SETPOINT DOWN for 5 seconds
During the test process, the word
"STEP" and the corresponding step
number will be lighted on the
display. After the final step has been
executed, the controller will exit
Manual test and force the controller
to into a reset.
Manual test mode may be cancelled
by pressing any button on the
display.
Manual test is not available if there is
no interface module, as is in Class 2
control applications.
The test sequence attempts to clear
unit diagnostics and restore normal
unit operation prior to testing the
outputs. If the diagnostics remain
after an attempt to clear them,
manual test may be affected or
disallowed.
Dehumidification
The PTAC controller does not directly
measure room humidity.
The PTAC provides dehumidfication
by combining the following actions
in a predefined sequence.
1. The PTAC subcools the room to a
preset state, a dehumidification
offset below the cooling setpoint.
2. The unit will automatically adjust
the fan speed.
3. When incorporating the vent
door option, the controller will
automatically adjust its position.
