Introduction
The ProSpace™ Packaged Terminal Air Conditioners
and heat pumps provide a high standard of quality in
performance, workmanship, durability and appearance
as they heat and cool the occupied air space year
round.
This manual provides information for ease of
installation, operation and maintenance. All models are
designed for through–the–wall installation. Separate
installation instructions are included with all accessory
components.
General Information
Read this manual completely and carefully before
starting any work. Write down the model and serial
number on the space provided on the product
registration card. The model and serial number can be
located on the serial number plate attached to the unit.
These numbers are required for any service work.
I m p o rt a n t : Ensure that this manual is left with the
owner for future reference. Observe all
local codes and ordinances.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required. Your personal safety and the proper
operation of this machine depend upon the strict
observance of these precautions.
Important Responsible Refrigerant
Practices
Trane 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,
reclaiming, recovering and recycling 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.

serious injury.
Indicates a potentially hazardous situation
which, if not avoided, could result in minor or

accidents.
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. Trane advocates the
responsible handling of all refrigerants-including

Unit Features
This unit has many features that are different from those found on standard PTAC models. The
owner should become familiar with these features in order to fully understand the operation and
capabilities of the unit:
Intelligence
The unit has an on board computer which utilizes real-time diagnostics to prolong the life of the
unit. There is an LED indicator on the control board, behind the front panel, that flashes an error
code if the unit detects a faulty condition. In many situations, the unit automatically clears the
fault condition and continues operating with no interruption. However, In some cases, the
condition cannot be cleared and the unit will require servicing. In those situations, an F x failure
mode displays on the digital display.
N o t e : Refer to the diagnostic codes in the section,“Intelligent Self-Checking Control,” p. 23.
Memory
In the event there is a power lost, all of the control settings (Setpoint, Mode, Fan Speed, ON/OFF
and Configuration) are retained in memory. After power is restored, the unit starts back up in the
previous mode (and configuration) prior to a power loss.
Quiet Design
The ProSpace has two (2) fan motors and a tangential blower wheel for optimum quietness. The
indoor fan always runs, at a minimum of 10 seconds, before the compressor in order to reduce
the sound of the compressor starting.
Random Compressor Restart
The compressor is equipped with a 2–minute, 45 second to 3–minute 15 second random restart
delay feature. This helps to prevent power surges after a power outage (for example, when many
PTACs start at the same time). Whenever the unit is plugged in, or when power has been
restarted, a random compressor restart occurs to help avoid power surges.
Compressor Protection
The ProSpace has a random start-up delay of three (3) minutes on the compressor, with a
minimum compressor run time of three (3) minutes, to prevent short cycling of the compressor
and to maximize its life.
Automatic Room Freeze Protection
This protection feature automatically ensures the indoor temperature does not fall below
freezing. When the PTAC is configured for freeze protection (the default condition), the power is
supplied to the unit, and if the unit senses a temperature below 40°F, the fan motor and electric
heater turn ON and warms the room to 50°F (10°C). The unit can be configured to have freeze
protection turned OFF.
Automatic Quick Warm-Up (Heat Pump Models Only)
If the room temperature falls to 5°F (-15°C) below the setpoint temperature, the reverse cycle heat
is shut OFF and the electric strip heat is turned ON for one (1) cycle, until room temperature rises.

N o t e : Under cooling or heating mode, the Dual-8 displays the set temperature and (the Dual-8
displays indoor ambient temperature under fan mode.
•
D i s p l a y D a t a w i t h 3 – b i t s : the Dual-8 displays a ten digit + the unit digit at first and then
displays BLANK + hundred digit.
Fan Configuration Optimization for Selected Application
The unit can be optimized for selected applications by configuring the fan to run in Continuous
mode or cycle ON/OFF with the compressor and electric heater (can be different for both heating
and cooling modes). In cycle mode, the fan continues to run after the compressor or electric
heater stops in order to blow off any residual heat or cool left on coil.
Other Unit Configurations

•
Display either Fahrenheit (F°) or Celsius (C°).
•
Optimize the room temperature sensor reading to the exact application— one for cooling, one
for drying, and one for heating (indoor temperature sensor biasing).
•
Emergency Heat (for Heat Pump Only); disable the compressor during heating mode
operation (heat only with Electric Heat).
•
Configure the unit to display only the room temperature or setpoint during heating and
cooling modes.
•
Configure the unit to limit the controlling setpoint range. The display always shows the
complete setpoint range, but the controlling setpoint is limited to the configured minimum/
maximum setpoint selected.

•
Energy Management (also referred to as Front Desk Control); an input is provided so that the
unit can be manually disabled from a different location. If the unit detects 24 Vac on this input,
it automatically turns itself OFF. If no voltage is detected on the input, the unit runs normally.
•
Wall Thermostat Control; a wired wall thermostat can be connected to the unit. If so, the unit
must be configured to disable the keypad.

Power Connection Options
Appropriate power cord accessory kit is determined by the voltage and the amperage of the
branch circuit, based on the unit amperage requirements (for example, electric heater size). The
unit ships without a power cord.
N o t e : Ensure the outlet matches the appropriate prong configuration on the plug. It should be
within reach of the service cord. All wiring, including installation of the receptacle, must be
in accordance with the NEC™ and all local codes, ordinances and regulations. National
codes require the use of an arc fault or leakage current detection device on all 208/230V
power cords. For 265V units, if power cord accessory option is selected, then the cord is
only l8" long and must plug into the accessory electrical 265V sub-base.
All Units
I m p o rt a n t : Follow NEC and local electrical codes when installing electrical supply wiring. The
following is only shown as a sample.
Use recommended wire size (Table 1) and install a single-branch circuit. All units are designed to
operate off only one (1) single branch circuit.
N o t e : Only use copper conductors. Branch circuit wire is single circuit from main box. AWG wire
sizes are based on copper wire at a 140°F (60°C) temperature rating.

Voltage Supply
Check voltage supply at outlet. For satisfactory results, the voltage range must always be within
the ranges specified on the data information plate. Power cord does not ship with the unit. The
cord to order is determined by the unit voltage and the desired electric heat capacity.
Cord/Connected Units
The 250 Vac field supplied outlet must match the plug for standard 208/230V units and be within
reach of the service cord.
N o t e : Do NOT use 30 amp cord with size 07 units.

Power Cord Protection
N o t e : Power cord does not ship with the unit.
The power cord for 230/208V units provide protection from fire. The unit power automatically
disconnects when unsafe conditions are detected. Power to the unit can be restored by pressing
the reset button on plug head. Upon completion of unit installation for 230/208V models, an
operational check should be performed using the TEST/RESET buttons on the plug head.
N o t e : Models with 265V do not incorporate this feature because they require use of an electrical
sub-base accessory. Connection to a wall socket is not permitted for 265V units. All 265V
units must be hard wired using the hard wire kit or make use of the plug-in receptacle in
the standard sub-base.

Trane Wall Sleeve and Grille
The image below shows the typical unit components that are ordered and installed.
I m p o rt a n t : Proper installation is the responsibility of the installer. Product failure due to
improper installation is not covered under warranty.
To install the Trane Wall Sleeve and Grille, refer to the latest installation instructions, PTAC-SVN028 and PTAC-SVN027.
Considerations for Use of Existing Sleeves
I m p o rt a n t : For retrofit applications, foam seals on outdoor coil tube sheets must make a seal
between the coil and the grill or loss of performance and premature damage to the
major components can result.

When it is necessary to work with li ve electrical components, have a qualified licensed
electrician or other indi vidual who has been properly trained in handling li ve electrical
components perform these tasks.
In applications when the unit is a replacement, it is recommended to use a Trane sleeve. This unit
can be retrofitted to other manufacturers similar sleeves if outdoor unit airflow is not restricted or
recirculated.
N o t e : Ensure the outdoor grille is installed on the sleeve. For any sleeve retrofit applications, be
sure that the foam seals (factory installed on the tube sheets) provide a good seal between
the grille and outdoor coil tube sheets. These foam seals provide a barrier that stops the
inside air from mixing with the outside air (known as air recirculation).
PTAC-SVX002A-EN

Installation
I m p o rt a n t : Inspect the wall sleeve thoroughly prior to installation. The manufacturer does not
assume responsibility for costs or damage due to defects in the sleeve or for
improper installation.

B E ST P R AC T I C E :
Check your local city/state for proper recycling procedures. A battery is an electrochemical device
with the ability to convert chemical energy to electrical energy to provide power to electronic
devices. Batteries contain heavy metals such as mercury, lead, cadmium, and nickel, which can
contaminate the environment when batteries are improperly disposed of. When incinerated,
certain metals might be released into the air or can concentrate in the ash produced by the
combustion process. Batteries may produce the following potential problems or hazards:
•
26
Pollute the lakes and streams as the metals vaporize into the air when burned
•
Contribute to heavy metals that potentially may leach from solid waste landfills.
•
Expose the environment and water to lead and acid.
•
Contain strong corrosive acids. May cause burns or danger to eyes and skin.

Care and Cleaning
Periodic care and cleaning of the ProSpace unit is essential to keep it running efficiently.
Front Panel and Case
Turn unit off and disconnect power supply. To clean, use a soft brush, water, and a mild
detergent. D O N OT use bleach or abrasives. Some commercial cleaners may damage the plastic
parts.
Outdoor Coil
I m p o rt a n t : Product failure due to improper care or lack of maintenance is not covered under
warranty. Airflow restriction may cause damage to the unit.
Coil on outdoor side of unit should be checked regularly. Unit will need to be removed from its
sleeve to inspect dirt build-up that can occur inside of the coil. If clogged with dirt or soot, the coil
should be professionally cleaned.
N o t e : Never use a high-pressure sprayer on the coil.
Base Pan
Periodically check the base pan and clean if required.
Air Filter
I m p o rt a n t : Do not the operate unit without filters in place. If a filter becomes torn or damaged, it
should be replaced immediately. Operating without filters in place or with damaged
filters will allow dirt and dust to reach indoor coil and reduce cooling, heating,
airflow, and the efficiency of the unit. Airflow restriction may cause damage to unit.
This unit contains two (2) air filters. To maintain unit efficiency, clean the filters at least every 30
days (or sooner depending on application). Keeping filter clean:
•
Decreases the cost of operation.
•
Saves energy.
•
Prevents a clogged indoor coil.
•
Reduces the risk of premature component failure.
To clean the air filters, vacuum off any heavy soil and contaminates. Run water through the filters
and then dry thoroughly before replacing them back into the unit.

Possible Causes
Resolution
•
Low outdoor temperature.
•
•
Dirty air filters.
When the outdoor temperature is
approximately 55°F (12.7°C) or below,
frost may form on the indoor coil when the
unit is in cooling mode. Switch unit to FAN
mode until the ice or frost melts.
•
Remove and clean the air filters.
•
Random Compressor Restart;
whenever the unit is plugged in or the
power has been restarted, a random
compressor restart occurs. After a power
outage, the compressor restarts after
approximately three (3) minutes.
•
Compressor Protection; to prevent
short cycling of the compressor, there is a
random star-up delay of three (3) minutes
and a minimum compressor runtime of
three (3) minutes.
•
Power may have cycled so the compressor
is in a restart protection mode.
If the circuit breaker is tripped or the fuse has blown more than once, contact a qualified electrician.
If the unit is installed where condensation can drip into unwanted areas, install an accessory drain kit and connect it to the
draining system.
