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.
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
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 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.

Step 9. Programmable
Settings
The controller has a total of six (7)
parameters that are userconfigurable:
1.Vent Door Configuration
2.Indoor Fan Cycle configuration
3.Temperature Setpoint Limiting
configuration
4.Energy Management Setpoint
Offset configuration
5.Display Units configuration
6.Indoor Temperature Calibration
7.DH Offset
The interface module texts
“SETTING” and “STEP” provide user
feedback when the unit is in the
configuration mode. The number
directly above the word “STEP”
indicates the configuration step that
is being adjusted. The numbers
above the word “SETTING” (XX.x)
indicate the value of the parameter.
In order for the user to access the
configurable parameters, a digital
display module must be present.
The configuration set-up mode is
entered by pressing and holding the
"MODE" and "FAN" buttons
simultaneously for 5 seconds.

Installation
1.Ventilation Door Function
The power door works based upon
control logic functions. When the unit
is on, the vent door will open to allow
fresh air to be conditioned before
entering the room. When the unit is
off, the door closes to prevent
unconditioned air from entering the
room.
For more information on vent door
function with dehumidificaiton, refer
to the dehumidification chart.
2.Indoor Fan Cycle set up
The indoor fan can be configured to
provide different types of operation
between its OFF and ON (high/low)
states. This setting is adjustable and
does not force the unit to reset.
3.Temperature Setpoint Limiting
set up
The range of temperature control
setpoints can be limited using this
configuration parameter. After the
controller has determined the
desired user setpoint from the
display, the resulting value is
validated against the setpoint limits.
There are four valid combinations of
heating and cooling setpoint limits:
These set point limits apply to both
the occupied and unoccupied
standby, heating and cooling
setpoints. This setting is adjustable
“on-the-fly” and will not force the
unit into a restart condition.
4.Energy Management Setpoint
Offset set up
The range of the Energy
Management System's effect on
setpoints can be adjusted using this
configuration parameter. This
parameter is adjustable "on-the-fly"
and will not force the controller into a
restart condition. The range and
resolution of available selections is
Range: 0°F to 20°F( 0.0°C to 11.0°C)
Resolution: 1.0°F( 0.5°C)
5.Display Unit set up
The user can change the way the
interface module displays
temperature. The symbols °F and °C
will not be present on the display;
however, the range and precision of
the room temperature and setpoint
values will make the selection
obvious.
6.Indoor temperature calibration
The indoor temperature can be
calibrated to match an independent
reading. The adjustment range is +/-
10.0°F (6°C) with a resolution of 1°F
(0.5°C).
7.Dehumidification Offset
The offset defines the point below
the setpoint where the unit will stop
running the compressor. A DH
display module is required to use this
feature.
The PTAC allows the options of 0°F
(disable), 1°F (default) and 2°F
(optional) for the dehumidification
offset. The dehumidification feature
will be disabled when the
configuration of 0°F is selected.
Last User Setpoint, Mode, and
Fan Selections
The controller saves the last inputs
that the user has chosen 5 seconds
after the user has ceased changing
them. These settings will be used
after the next power cycle or
controller reset.
Operation without configuration
The controller tests the configuration
for validity. If the data is corrupted
the controller will revert to default
values for every parameter. A
diagnostic code will be displayed
when using the default values.

Installation
Energy Management
System
Occupancy States
The controller is designed to handle
two possible occupancy states:
•occupied
•occupied standby
When the Energy Management
System input is present, it is possible
for the controller to switch between
the two occupancy states.
If the EMS input is not connected, the
controller will always assume the
occupied state.
Table 13. Occupancy arbitration for
energy management
EMS Input State
Open or Not PresentOccupied
ClosedOccupied Standby
Occupied state
When the controller is in the
occupied state, the unit runs space
comfort control using the occupied
setpoints. All heating/cooling/
ventilation features are enabled.
Controller
Occupancy State
Occupied Standby state
When the controller is in occupied
standby state, the unit runs space
comfort control using the occupied
standby setpoints. All heating/
cooling/ventilation features are
enabled. Because the occupied
standby setpoints cover a wider
range than the occupied setpoints
the demand for heating and cooling
the space is reduced.
After the compressor cycles off, it
will not restart for three minutes.
This feature prevents the
compressor from short cycling and
extends the overall life.
Automatic 2nd Stage Electric
Heat (PTHE only)
If the room temperature falls to 2.5°F
below the setpoint temperature or
the unit compressor fails, the reverse
cycle heat is shut off and the electric
heat is turned on.
Indoor Room Freeze
Protection
When the unit senses room
temperatures of 40°F or below, the
unit activates the indoor fan motor
and either the electric resistance
heater or the hydronic heater to help
prevent pipes or fixtures from
freezing.
This also overrides the Energy
Management System input for unit
mounted or wall mounted display
modules
Random Restart Function
This function allows random restart
of the PTAC units in the event of a
power outage. The restart delay
reduces the initial inrush current
from the building to help prevent a
second power outage caused by too
much current draw.
The random restart function will
occur after every power up cycle by
delaying the operation of the unit for
0 to 90 seconds. Compressor
minimum off time is enforced after
the random restart function has
completed.
Door Switch Occupancy
Sensor
The PTAC can accommodate a fieldinstalled door switch and occupancy
sensor to operate the energy
management feature.
Remote Thermostat Control
Each unit can be operated from any
standard 4 or 5-wire, remotemounted thermostat. Also, the unit
has a built-in low voltage power
source that can accommodate either
a manual, auto changeover, or
programmable thermostat.
Setpoint Limiting
The setpoint limiting feature reduces
energy costs by controlling the
maximum setpoint in heating and
the minimum setpoint in cooling.
Active Defrost (PTHEs only)
PTACs have an active defrost system
that removes ice build-up on the
outdoor coil, which may occur
during the heat pump cycle.
Remote Thermostat
Operation
The GL, GH, O, W, Y, R, and C
terminals provide control inputs for a
remote wall-mounted thermostat.
The terminals listed control the
operation of the unit when no
display module is used. A display
module will take precedence over
any of these inputs.
Mode Button Operation
OFF - cooling and heating functions
stop.
HEAT - room temperature is
maintained by cycling in heat pump
mode or electric heat. The model
PTHE switches from heat pump
mode to electric heat when the
outdoor air temperature is below
20°F (approximately), or when the
heat pump cannot keep up with the
heating load when using a two-stage
thermostat.
COOL - room temperature is
maintained by cycling the air
conditioner.
FAN - the fan runs at the user
selected speed or runs as otherwise
configured.
Fan
Figure 17.Digital display module
Mode
Fan Operation
The fan speed may be user selected
as either high or low. Fan cycling
versus continuous is operation
configurable. See section on
configuration for details.
Front Desk Control (FD1, FD2
Inputs)
The energy management input is
used to move the setpoint up in the
case of cooling and down in the case
of heating. This conserves energy
by reducing the demand in the
space.
The energy management input is a
dry contact closure; typically this is
driven from either a occupancy
sensor or a front desk control
system.

Remote Fan Operation
PTACs can operate a remote fan to
provide conditioned air to additional
rooms or areas that are not well
ventilated. The remote fan operates
any time the PTAC indoor fan is
operating.
The remote fan requires a 24 VAC, 3
VA maximum relay that connects to
the control board RF and C terminal
user inputs. The relay and remote fan
are field supplied. Refer to the wiring
diagrams section for wiring details.
CAUTION
Freezing Temperatures!
Do not allow liquid refrigerant to
contact skin. If it does, treat the
injury similar to frostbite. Slowly
warm the affected area with
lukewarm water and seek immediate
medical attention. Direct contact
with liquid refrigerant may cause
minor or moderate injury.
Air Discharge Grille
The discharge grille can be adjusted
to expel air at either a 15° or 40° (40°
default) angle. Figure 18.
To change the discharge air airflow
angle:
1.Remove the front cabinet.
2.Position the front cabinet so that
the backside is accessible.
3.Remove the four screws which
secure the discharge air grille to
the cabinet front with a phillipshead screwdriver. See Figure 31.
4.Rotate the grille 180° end-forend.
5.Reinstall the screws securing the
discharge air grille to the cabinet
front. Reinstall the cabinet front
on the unit.
Screws
Vent Control
Vent control draws fresh air into the
conditioned area to provide
ventilation when the indoor fan is
operating. However, this may
increase heating cooling loads and
operating costs.
To obtain access to the vent control,

procedures to ensure proper unit
operation.
WARNING
Live Electrical Components!
During installation, testing, servicing
and troubleshooting of this product,
it may be necessary to work with
live electrical components. Have a
qualified licensed electrician or other
individual who has been properly
trained in handling live electrical
components perform these tasks.
Failure to follow all electrical safety
precautions when exposed to live
electrical components could result in
death or serious injury.
WARNING
Hazardous Voltage!
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.
Chassis
Clean the chassis every four months
or more often as the atmospheric
conditions require. Use water and
detergent to clean the basepan,
center partition and coils.
Using harsh cleaning materials may
cause a deterioration of the coil fins
or end plates.
Do not use a high pressure cleaner
as it could cause severe damage to
the PTAC fins and coils.
Note: It is very important to not get
any of the electronic parts
wet.
A hose is okay to use to clean the
coils, but make sure to cover the
control with a blanket or plastic bag
to prevent it from getting wet.
Wall Sleeve
Clean the wall sleeve every four
months or more often as the
atmospheric conditions require.
Remove any debris from the bottom
of the panel, and from around any
internal or external drain kit
accessory item prior to using water
or detergent. This will ensure that no
debris clogs up the drain holes.
The use of harsh cleaning materials
may cause a deterioration of the
bottom panel over time. Do not use
a high pressure cleaner because it
could spray the side or top panel
insulation material and cause future
air quality problems like mold and
mildew.
Clean side and top panel insulation
material with a lint brush or piece of
tape. Press tape against insulation
lightly and slowly peel away to
remove dirt and debris.
Compressor/Fan Motor
The compressor and fan motor are
hermetically sealed, permanently
lubricated, and require no additional
oiling.
Cabinet Front
The cabinet front and discharge air
grille can be cleaned with a mild
soap or detergent.
Under NO circumstances should
hydrocarbon based cleaners (e.g.
acetone, benzene, naphtha gasoline,
etc.) be used to clean the front or air
grilles.
Use care when cleaning the control
area. Do not use an excessively wet
cleaning cloth.
Intake Air Filter
The intake air filter and vent door
filter are both constructed of durable
polypropylene. Clean filters monthly
to ensure proper unit operation.
The fan must be off before the filters
are cleaned.
To remove the air filters, grasp the
top of the filter and lift out of the
front cabinet (Figure 19.) Reverse the
procedure to reinstall the filters.
Figure 19.Intake air filter removal
is through top of unit. Inspect and
clean filters monthly for proper unit
operation.
Vent Filter
Before cleaning the vent filter,
disconnect power to the unit by
unplugging the power cord at the
wall outlet or subbase, or disconnect
power at the fuse box or circuit
breaker. If unit is operated with vent
door closed, the vent filter does not
need to be cleaned.
1.Remove the cabinet front as
described in front removal.
2.Remove the six screws securing
the chassis to the wall sleeve
with a Phillips-Head screwdriver.
3.Slide the chassis out of the wall
sleeve far enough so that the
vent filter is accessible as shown
in Figure 20.
4.Remove the vent filter by
unscrewing the two screws at
the top of the filter and gently
pulling the filter away from the
partition panel. Refer to
Figure 21. The filter can be
cleaned by running under a low
pressure hose or sink faucet.

of the hermetically sealed
refrigeration system should be taken
to a well equipped shop where
special equipment for evacuating,
dehydrating, charging and testing is
available. The following equipment is
necessary:
•Nitrogen of no more than 0.0012
grains of moisture.
•Vacuum pump capable of
evacuating to a minimum of 50
microns.
•Micron gauge to check vacuum
•Refrigerant charging cylinder
accurate to within 1/4 oz.
•Electronic leak detector
•Electrical equipment to test
compressors, capacitors, voltage
relays, and overload protectors
•Voltmeter, ammeter, and
wattmeter
•Silver soldering and brazing
equipment - Pinch off tools ¼ in
to 5/8 in
•Thermocouple tester
WARNIN G
Hazardous Pressures!
If a heat source is required to raise
the tank pressure during removal of
refrigerant from cylinders, use only
warm water or heat blankets to raise
the tank temperature. Do not exceed
a temperature of 150°F. Do not, under
any circumstances apply direct flame
to any portion of the cylinder. Failure
to follow these safety precautions
could result in a violent explosion,
which could result in death or
serious injury.
CAUTION
Freezing Temperatures!
Do not allow liquid refrigerant to
contact skin. If it does, treat the
injury similar to frostbite. Slowly
warm the affected area with
lukewarm water and seek immediate
medical attention. Direct contact
with liquid refrigerant may cause
minor or moderate injury.
Dehydrating and Evacuating
Refrigeration System
A rather popular misconception
exists that since air conditioners
normally operate with a refrigerant
temperature above 32°F, moisture in
the system is harmless. Nothing
could be further from the truth.
Oxygen from moisture plus normal
compressor and motor heat reacts
chemically with the refrigerant and
oil to form corrosive hydrochloric
and hydrofluoric acids. These acids
contribute to the break down of
motor winding insulation and the
corrosion of compressor working
parts and cause unnecessary
compressor failure.
Sludge, which is a residue of the
chemical reaction, coats all
compressor parts, the inside of
refrigerant tubing, and may even
restrict refrigerant flow through the
capillary tube(s).
PTAC-SVX01C-EN31
Maintenance
Leak Testing
Refrigerant leaks are best detected
with a halide or electronic leak
detector.
WARNIN G
Use of Pressure Regulator –
Valves – Gauges!
Always use pressure regulators,
valves, and gauges to control drum
and line pressures when pressure
testing equipment. Failure to follow
these instructions could result in an
explosion causing death, serious
injury, or equipment damage.
WARNIN G
Leak Testing!
Do not exceed 200 psig when leak
testing system. Failure to follow
these instructions could result in an
explosion causing death or serious
injury.
The importance of careful leak
testing cannot be over emphasized.
Undetected leaks invariably lead to
repeated calls and eventually result
in system contamination, restrictions
and burned out compressors.
For a system that contains a
refrigerant charge and is suspected
of having a leak, stop the operation,
check all tubing and fittings. Soap
suds may also be used.
Note: The flame of the halide
detector will glow green in
the presence of R22
refrigerant.
If a leak is detected, do not attempt to
apply more brazing material to the
joint. Recover the charge, unbraze the
joint, clean and rebraze.
For a system that has been newly
repaired and does not contain a
charge, connect a cylinder of
refrigerant, through a gauge
manifold, to the process tube of the
compressor and liquid line strainer.
Open the valve on the cylinder and
manifold and allow the pressure to
build up within the system. Check for
and handle leaks as described above.
After the test has been completed,
recover the test charge, evacuate the
system, and recharge with clean
refrigerant.
Brazing
WARNIN G
Hazard of Explosion!
Use only dry nitrogen with a
pressure regulator for pressurizing
unit. Do not use acetylene, oxygen or
compressed air or mixtures
containing them for pressure testing.
Do not use mixtures of a hydrogen
containing refrigerant and air above
atmospheric pressure for pressure
testing as they may become
flammable and could result in an
explosion. Refrigerant, when used as
a trace gas should only be mixed
with dry nitrogen for pressurizing
units. Failure to follow these
recommendations could result in
death or serious injury or equipment
or property-only damage.
CAUTION
High Temperatures!
Brazing requires high temperatures.
Direct contact with hot surfaces may
cause minor or moderate injury.
Satisfactory brazing results require
cleanliness, experience and the use
of proper material and equipment.
Verify brazing connections are
properly sized, free of rough edges,
and clean.
Use of these generally accepted
brazing materials:
•SIL-FOS (Alloy of 15% silver, 80%
copper, 5% phosphorus): use
without flux on copper to copper.
Note: DO NOT USE FOR A COPPER
TO STEEL CONNECTION.
Recommended heat is
approximately 1400°F.
•SILVER SOLDER (Alloy of 30%
silver, 38% copper, 32% zinc): use
with fluoride base flux on copper
to steel, brass to copper, steel to
steel, or brass to steel.
Recommended heat is
approximately 1200°F.

Evacuation
Figure 22.Refrigeration sealed system — heat pump (air conditioning
model
CAUTION
Fan Motor Overheat!
Never test operation without the
unit in the wall sleeve. A serious
change in design specifications for
air movement through the
evaporator and condenser
compartments, causing the fan
motor to over heat and the
refrigeration system to become
unbalanced will occur when the unit
is not installed in the wall sleeve.
CAUTION
High Temperatures!
Do not allow sludge or oil to contact
skin when evacuating refrigerant
from equipment. Direct contact with
sludge or oil may cause minor or
moderate injury.
Thoroughly evacuate the system
using a high vacuum pump, capable
of producing a vacuum equivalent to
50 microns and a thermocouple
vacuum gauge to give a true reading
of the vacuum in the system.
Note: Never use the system
compressor as a vacuum
pump or run when under a
high vacuum. Motor damage
could occur.
Figure 23.Refrigeration sealed system — Heat pump (heat pump model)
Evacuation Procedure
1.Connect the vacuum pump,
vacuum tight manifold set with
high vacuum hoses,
thermocouple vacuum gauge,
and charging cylinder.
2.Connect the low side line to the
process tube of the compressor.
3.Connect the high side line to the
process tube of the liquid line
strainer.
Note: If either process tube is not
long enough to receive the
compression or flare fitting
and still leave room for a
pinch-off, swag the tube and
braze in an extra length of
tubing.
PTAC-SVX01C-EN33
Maintenance
4.Start the vacuum pump and
open the shut-off valve to the
high vacuum gauge manifold
only. After the compound gauge
(low side) has dropped to
approximately 29 inches of
vacuum, open the valve to the
vacuum thermocouple gauge.
See that the vacuum pump will
bank-off to a minimum of 50
microns. A high vacuum pump
can only produce a good vacuum
if its oil is not contaminated.
5.If the vacuum pump is working
properly, close the valve to the
vacuum thermocouple gauge
and open the high and low side
valves or the high vacuum
manifold set. With the valve on
the charging cylinder closed,
open the manifold valve to the
cylinder.
6.Evacuate the system to at least
29 inches gauge before opening
valve to thermocouple vacuum
gauge.
7.Continue to evacuate to a
minimum of 250 microns. Close
valve pump and watch rate of
rise. If vacuum does not rise
above 1500 microns in three
minutes, system can be
considered properly evacuated.
8.If thermocouple vacuum gauge
continues to rise and levels off at
about 5000 microns, moisture
and non-condensables are still
present. A leak is present if the
gauge continues to rise. Repair
and re-evacuate.
9.Close valve to the thermocouple
vacuum gauge and vacuum
pump. Shut off pump and
prepare to charge.
Charging the System
Charge the system with the exact
amount of refrigerant. Refer to the
unit nameplate for the correct
refrigerant charge. An inaccurately
charged system will cause future
problems.
Charging Procedure
1.When using an ambientcompensated calibrated
charging cylinder, allow liquid
refrigerant only to enter the high
side.
2.After the system receives all the
refrigerant it requires, close
close the valve on the high side
of the manifold.
3.Start the system and charge the
balance of the refrigerant though
the low side. Do not charge in a
liquid form.
4.Close the low side valve on the
manifold and pinch-off both
process tubes. Remove the
manifold set. Crimp shut the
open ends of the process tubes
and braze.
5.Recheck for refrigerant leaks.
Refrigerant
Do not use a refrigerant other than
that shown on the unit nameplate.
Follow all precautionary measures
recommended by the refrigerant
manufacturers.
Line Piercing Valves
Line piercing valves may be used for
diagnosis but are not suitable for
evacuating or charging due to the
minute holes pierced in the tubing.
Line piercing valves must not be left
on the refrigerant system. The
connection between the valve and
the refrigerant tubing is not
hermetically sealed and will
eventually leak.
Open Lines
Never leave refrigerant lines open to
the atmosphere when processing the
refrigeration system. Water vapor
may enter the lines and cause
improper evacuation.
Operating Test
The final step in a successful repair is
an accurate operating test. Follow the
cooling and heating performance
tests on pages 36 - 37 to make sure
the product is performing to design
standards.
WARNING

Cooling Performance Test
Thermometers
The following precautions are
necessary in observing the
thermometer readings in the cooling
performance test.
1.Use two accurately calibrated
refrigeration type thermometers
or a thermocouple
potentiometer.
2.Thermometers are affected by
body heat or changes in airflow.
Therefore, secure the
thermometers in proper
locations with masking tape,
wire, or other applicable
retainers.
3.Observe readings without
touching or moving the
thermometers.
Sling Psychrometer
Use a sling psychrometer to obtain
the wet-bulb temperature and
determine the percent relative
humidity.
To obtain the wet-bulb, follow this
procedure using the sling
psychrometer.
•Saturate the wick (only once
during procedure of obtaining
wet-bulb readings) with clean
water slightly below room
temperature.
•Obtain the psychrometer reading
five to six feet in front of the unit
and approximately four feet off
the floor.
Note: Direct discharge airflow away
from the sling psychrometer.
Do not perform the cooling
performance test when the outside
temperature is 20°F below the room
temperature. For best results,
perform the test under peak load
conditions.
The air conditioner must operate at
least 20 minutes on the HIGH COOL
position before testing.
Cooling Performance Test
Record the following temperatures
for the cooling performance test:
•Dry-bulb temperature of return
air at conditioner. Locate
thermometer as illustrated on
previous page.
•Dry-bulb temperature of
discharge air. Locate the
thermometer as illustrated on
previous page.
•The dry-bulb thermometer
temperature on the sling
psychrometer should be plus or
minus 1°F within reading
obtained on thermometer in the
return air. Check wet-bulb
temperature on sling
psychrometer and record same.
•After recording the wet-bulb
temperature, dry- bulb
temperature, and return air
temperature, calculate the
temperature difference as
follows.
•Subtract temperature obtained in
Step B from temperature
obtained in Step A. Use the
remainder temperature to
calculate from the cooling
change of temperature in the
Maintenance general
information section.
Example: Assume a PTHE1501 unit is
under test and the temperature
readings indicated below were
obtained.
1.Return air dry-bulb temperature:
80°F, Step A.
2.Discharge air dry-bulb
temperature: 69°F, Step B.
3.Return air, wet and dry-bulb
temperature as recorded in Step
C: dry- bulb 80°F, wet-bulb 75°F.
4.In left hand column of cooling
capacity charge headed dry-bulb,
find the 80° value in Table 20,
p. 25.
5.In column headed wet-bulb find
the 75° value and find the value
"8 -13" in the cooling range
column under model
“PTHE1501”.
This data shows the temperature of
the air passing through the cooling
coil is reduced at least 8°F but not
more than 13°F. This example unit is
operating normally for the existing
conditions.
For the example unit under test, the
temperature difference was 11°F
(80°F, return air, minimum 69°F
discharge air). Because the value is
within the listed cooling range 8 - 13,
this unit is considered to be
operating normally.
Note: Never test operation without
the unit in the wall sleeve. A
serious change in design
specifications for air
movement through the
evaporator and condenser
compartments, causing the
fan motor to over heat and
the refrigeration system to
become unbalanced will
occur when the unit is not
installed in the wall sleeve.
Electric Heat Test
For the electric heat test, the
following readings must be recorded
after the unit is interconnected with a
wattmeter or by recording the total
amp draw to the unit.
Note: The cabinet front must be in
place during this test.
•Record supply voltage to unit.
•Operate unit in highest heat
setting.
•Record wattage recorded on
wattmeter or total amp draw to
unit.
•Refer to the electric heat capacity
and electrical data section
(whichever is applicable for
voltage rating on the unit being
tested.)
•The total watts or amps recorded
should fall with in the minimum
and maximum watts/amps listed
on these charts
Example: Assume that a PTHE1501
230/208V with 3.5 kW electric heater
is under test.
1.Supply voltage as recorded 208V.
2.Watts recorded -2750W or amps
recorded - 13.5 amps.
PTAC-SVX01C-EN35
Maintenance
3.Locate the readings listed in the
Operation section of this manual.
You will note that these readings
fall within the voltage, watts and
amp draw minimum and
maximum ranges listed.
Therefore, the unit heating
performance would be
considered normal.
Heating Power Consumption
Te s t
(Heat Pump Mode Only)
For the heating wattage, record the
following readings after the unit is
interconnected with a wattmeter.
•Outside coil inlet air dry-bulb
temperature.
•Inside coil inlet air dry-bulb
temperature.
•Total watts input measured by
wattmeter.
Calculating procedure
1.Locate temperature obtained in
Step A of cooling performance
test in first column of Heating
Wattage Chart.
2.Locate in second column the
inside coil inlet dry-bulb
temperature.
3.The total watts input should
come between minimum and
maximum values indicated for
each model.
Example: Assume that a PTHE1501 is
under test. Proceed as follows and
observe test readings as
simultaneously as possible.
1.Outside coil inlet dry-bulb
temperature readings as
described above: 45°F.
2.Check watts input: 1370 W
3.Inside coil inlet dry-bulb
temperature reading as de
scribed in Step B: 75°F.
Read to the right from the 75° inside
coil inlet dry-bulb value in the
column and note the minimum and
maximum wattage of 1335 - 1470.
Since the wattage reading (1370)
obtained in the test is within the
prescribed range, the total power
input in watts is considered to be
normal.

Reversing Valve
Occasionally the reversing valve may
stick in the heating or cooling
position or in the mid-operation.
When stuck in the mid-position, part
of the discharge gas from the
compressor is directed back to the
suction side resulting in excessively
high suction pressure.
Check the operation of the valve by
starting the system and switching the
operation from COOLING to
HEATING and then back to COOLING.
If no voltage is registered to the coil,
check the operation of the reversing
relay and the continuity of the
connecting wires.
If voltage is registered at the coil, tap
the valve body lightly while switching
the system from HEATING to
COOLING etc. If this fails to cause the
valve to switch position, remove the
coil connector cap and wiring and
test the continuity of the valve coil. If
the coil does not test continuous
replace it.
If the valve is inoperative, replace.
Component Replacement
Replacement of the compressor,
evaporator, condenser, capillary
tubes and reversing valve must be in
accordance with accepted service
practices. These procedures include
a complete evacuation of both high

capillary tube assembly whenever
the refrigerant system is opened.
Before replacing a component in the
sealed system, make sure that the
cause for complaint does not lie in
the electrical circuit, control, overload
or is due to some other reason. The
serviceman must be familiar with the
operational characteristics of the
product and should not jump to
conclusions.
The PTHE is equipped with a
temperature-actuated drain valve

board if the jumper is not
properly set.
4.Remove connections from the
existing control board, tagging
wires as required to ensure
correct re-assembly.
5.Remove 2 screws from the front
plastic mounting ears. Remove
the screw from the green wire
ground. Slide plastic chassis and
board back and lift out of place.
6.Engage catches on bottom of
plastic chassis of replacement
assembly with sheet metal
control box and slide forward to
lock in position. Re-install two
screws through the front plastic
mounting ears. Re-install green
ground wire.
7.Re-connect the wiring harness to
the new assembly in the same
positions that they were before
removal. This includes
temperature thermistors, as well
as the thermostats, zone sensors
and energy management.
8.Reinstall the sheet metal cover
over the control board.
9.Position the front cabinet over
the chassis and push the sides
until the retaining clips engage.

Troubleshooting
Diagnostics
The controller is equipped to display
a diagnostic code through the
interface module; if the display is not
present (Class 2 control), there is no
method to retrieve the diagnostic
codes from the unit.
If there is no interface module to
indicate the presence of a diagnostic,
service will only be triggered by a
comfort or operational complaint.
The controller will only display the
most severe diagnostic present.
Translating Multiple
Diagnostics
The controller senses and records
each diagnostic independently of
other diagnostics. It is possible to
have multiple diagnostics affect the
operation of the unit, but only the
most severe diagnostic will be
displayed.
Resetting Diagnostics
A reset clears any latching
diagnostics and allows the control to
try to run the PTAC normally. If the
latching condition is still present
after the reset, the control will shut
down the PTAC. A reset will reset a
unit that is running normally. A reset
is just like cycling power to the unit.
There are two ways to reset
diagnostics:
1.Manual output test at the
controller
2.Cycling power to the controller
Manual Output Test
When manual test has been initiated,
the controller exercises all outputs in
a predefined sequence. The last step
of the sequence resets the controller.
See the Manual output test section
on page 22 for more information
about the manual output test.
Cycling Power
When someone turns off the
controller’s power, then re-applies
power, the unit cycles through a
power up sequence. By default, the
controller will attempt to reset all
diagnostics at power up.
Diagnostics present at power up and
those that occur after power up will
be handled according to the defined
unit diagnostics sequences (see
Diagnostics table below)
