UNIT FEATURES
This Premium unit has many exciting features which are different than those found on standard PTAC
models. The owner must be familiar with these features in order to fully understand the operation and
capability of the unit.
• Intelligence – Your Premium unit has an on board
computer that utilizes real time diagnostics to prolong
the life of your unit. There is an LED indicator on the
control board, behind the front panel, that will flash
an error code if the unit has detected some kind of
fault condition. In many cases, the unit will automatically
clear the fault condition and continue operating with no
interruption. In some cases, the condition cannot be cleared
and the unit will require service. In those cases, an “Fx” failure
mode will be displayed on the digital display. For a detailed list
Fig. 2
of all error codes and “Fx” conditions, see Table 6 -Status LED
Indicator Definitions for further details.
• Memory – Your Premium unit also has memory. If power is lost, all of the control settings (setpoint,
mode, fan speed, on/off and configuration) are remembered. So when power is restored, the unit will
start back up in the mode (and configuration) it was in, when power was lost.
• Premium Sound – The unit not only doe s it have 2 fan motors and a tangential blower wheel for
optimum sound, the outdoor fan will always run a minimum of 10 seconds before the compressor, to
help reduce any compressor starting noise.
• Random Compressor restart - To help prevent power surges after a power outage (from many of
your PTACs starting at the same time), the compressor is equipped with a ″165 to 195″random
restart delay feature.Whenever the unit is plugged in, or power has been restarted, a random compressor
restart will occur.
• Compressor Protection - To prevent short cycling of the compressor and maximize it’s life, there is a
random start-up delay of 3 minutes on the compressor and a minimum compressor run time of 3 minutes.
• Automatic roomfreeze protection – automatically will keep the temperature in the room from getting
too cold, where water pipes might freeze. If the unit is configured for the freeze protection feature to be
active (which is the default condition), then whenever power is supplied to the unit, if the unit senses
temperature below 40°F, the fan motor and electric heater are turned on and will warm the room to 50.
If Freeze protection is not required, change the configuration switch to turn the feature off (see section
on unit configuration).
• Automatic Quick Warm-up (for heat pump models only) - If the room temperature falls to 5°F
below the set point temperature, the reverse cycle heat is shut off and the electric strip heat is turned on.
1. Mode indicator display: When the air conditioner operates in a certain mode, the corresponding mode
indicator will be bright;
2. The ON /OFF indicator is in green when the controller is ON and in red when controller is OFF.
3. Fan speed display: When air conditioner operates at high, medium, low or auto fan speed, the
corresponding indicator will be bright.
4. Dua-8 display: Ambient temperature can also be displayed in cooling and heating modes through setting the
dial switch. Under cooling or heating mode, the dual-8 will display the set temperature (the dual-8 will display
indoor ambient temperature under fan mode).
5. If the display data has three bits, the dual-8 will display “ten’s digit”+ “unit’s digit” at first and then
display “BLANK”+ “hundred’s digit”. for one cycle, until heating is satisfied.
• Dual-8 Display and LED Display -- Two 8-segment nixie tubes, eleven LED indicators
(They are HIGH,LOW,AUTO,DRY,COOL,FAN,HEAT,ON/OFF,SETPOINT,INDOOR,TIMER)
• Configure Fan to Optimize Selected Application - Unit can be optimized to selected application by
configuring the fan to run in continuous mode or cycle on and off with the compressor and electric
heater (can be different for both heating and cooling modes). In cycle mode, fan will continue to run after
compressor or electric heater stops in order blow off any residual heat or cool left on coil.

• Emergency Heat (for Heat Pump Only) –Disable the compressor during heating mode operation (heat
only with Electric Heat).
• Display Setpoint OR Room Temperature –The unit can be configured to display the room
temperature OR setpoint only, during heating and cooling modes. See section on unit configuration for
more details.
• Limit the Setpoint Range –The unit can be configured to limit the controlling setpoint range.The
display will always show the complete setpoint range, but the controlling setpoint will be limited to the
configured minimum and maximum setpoint selected. See section on unit configuration for more details.
• Energy Management – Sometimes known as Front Desk Control, an input is provided so that the
unit can be manually disabled from a different location. If the unit detects 24vac on this input, it will
automatically turn itself off. If no voltage is detected on the input, the unit will run normally.
• Wall Thermostat Control – A wired wall thermostat can be connected to the unit. If it is, the
unit must be configured to disable the keypad. See section on wired inputs and unit configuration for

ELECTRICAL DATA
WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death and/or property damage
DO NOT alter cord or plug or use an extension cord.
POWER CONNECTION OPTIONS
Appropriate power cord accessory kit is determined by the voltage, and amperage of the branch circuit.
IMPORTANT: For 265V units, if power cord accessory option is selected, the cord is only 18”
long and must plug into the accessory electrical 265V subbase.
Be sure that your outlet matches the appropriate blade configuration of the plug and that it is within reach of
the service cord. All wiring, including installation of the receptacle, must be in accordance with the NEC
and 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. Be sure to select the correct cord for your installation.
ALL UNITS

INSTALLATION
Proper installation is the responsibility of the installer.
Product failure due to improper installation is not covered under the Warranty.
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended that a
AC Prosleeve be used.
These units can retrofit General Electric, Amana, Trane, and Friedrich sleeves/grilles (be sure outdoor
grille is installed on the sleeve). See Table 3 for details.
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 to
separate outdoor coil leaving air from mixing with the outdoor incoming air (known as air recirculation).

CARE AND CLEANING
FRONT PANEL AND CASE
Turn unit off and disconnect power supply.
To clean, use water and a mild detergent. DO NOT use bleach or abrasives. Some commercial cleaners
may damage the plastic parts.
OUTDOOR COIL
Coil on outdoor side of unit should be checked regularly. Unit will need to be removed to inspect
dirt build--up that will occur on the inside of the coil. If clogged with dirt or soot, coil should be
professionally cleaned.
NOTE: Never use a high--pressure spray on coil.
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Airflow restriction may cause damage to the unit.
Coils
Grille
Clean inside and outside of outdoor coils regularly.
Fig.27-Outdoor Coil
BASE PAN
In some installations, dirt or other debris may be blown into unit from outside and settle in base pan
(bottom of unit).
In some areas of the United States, a “jell--like“ substance may be seen in the base pan. Check base
pan periodically and clean, if necessary.
AIR FILTERS
IMPORTANT: TURN UNIT OFF BEFORE CLEANING
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not 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 efficiency of unit. Airflow restriction may cause damage to unit.
Themost important thing you can do to maintain unit efficiency is to clean the filters at least every 30 days
(or sooner depending on application). Clogged filters reduce cooling, heating and airflow.
Keeping filters clean will:
Decrease cost of operation.
Save energy.
Prevent clogged indoor coil.
Reduce risk of premature component failure.
To Clean Air Filters:
Vacuum off heavy soil.
Run water through filters.
Dry thoroughly before replacing.

TROUBLESHOOTING
POSSIBLE CAUSES
UNIT DOES NOT START
• Unit may have become unplugged
• Fuse may have blown
• Circuit breaker may have been tripped
• Unit may be off or in wall thermostat mode.
Check section on dipswitch settings to verify
dipswitches are set properly.
• Unit may be in a protection or diagnostic failure
mode. See section on Intelligent Self-checking
Control.
SOLUTIONS
• Check that plug is plugged securely in wall receptacle.
Note:Plug has a test/reset button on it. Make sure that the plug
has not tripped.
• Replace the fuse. See Note 1.
• Reset circuit breaker. See Note 1.
• Turn unit on (bottom right button on keypad).
Note : If the unit turns on, the LED will be green. If the unit is off,
the LED will be red. If there is no LED on, there is a problem
with power or damage to the control.
UNIT NOT COOLING/HEATING ROOM
• Unit air discharge section is blocked
• Temperature setting is not high or low enough
Note : Setpoint limits may not allow the unit to heat
or cool the room to the temperature desired.
Check section on dipswitch settings.
• Unit air filters are dirty.
• Room is excessively hot or cold when unit is started.
• Vent door left open
• Unit may be in a protection or diagnostic failure
mode. Check section on Intelligent Self ---checking
Control.
• Compressor is in time delay. There is a protective
time delay (approx. 3 minutes) on starting the
compressor after a power outage (or restarting
after it has been turned off), to prevent tripping of
the compressor overload.
• Make sure that curtains, blinds or furniture are not restricting or
blocking unit airflow.
• Reset to a lower or higher temperature setting.
• Remove and clean filters.
• Allow sufficient amount of time for unit to heat or cool the room.
Start heating or cooling early before outdoor temperature, cooking
heat or gatherings of people make room uncomfortable.
• Close vent door.
• Check dipswitch settings for desired comfort.
DISPLAY HAS STRANGE
NUMBERS/CHARACTERS ON IT
• The unit may be in a diagnostic condition. Check Intelligent Self --checking Control section to determine if unit has had a failure.
• The unit may be set for℃(instead of F), see the keypad
configuration section.
UNIT MAKING NOISES
• Clicking, gurgling and whooshing noises are normal during
operation of unit.
• If a drain kit has not been installed, condensation runoff during
very hot and humid weather is normal. See Note 2. If a drain kit has
been installed and is connected to a drain system, check gaskets
and fittings around drain for leaks and plugs.
WATER DRIPPING OUTSIDE
WATER DRIPPING INSIDE
• Wall sleeve is not installed level
Wait approximately 3 minutes for compressor to start.
o
• Wall sleeve must be installed level for proper drainage of
condensation. Check that installation is level and make any
necessary adjustments.
ICE OR FROST FORMS ON INDOOR COIL
• Low outdoor temperature
• Dirty filters
• When outdoor temperature is approximately 55 F or below, frost
may form on the indoor coil when unit is in Cooling mode. Switch
unit to FAN operation until ice or frost melts.
o
• Remove and clean filters.
COMPRESSOR PROTECTION
• Power may have cycled, so compressor is in a
restart protection.
• Random Compressor restart --- Whenever the unit is plugged in,
or power has been restarted, a random compressor restart will
occur. After a power outage, the compressor will restart after
approximately 3 minutes.
• Compressor Protection -To prevent short cycling of the
compressor, there is a random startup delay of 3 minutes and a
minimum compressor run time of 3 minutes.
NOTES:
1. If circuit breaker is tripped or fuse is blown more than once, contact a qualified electrician.
2. If unit is installed where condensation drainage could drip in an undesirable location, an accessory drain kit should be installed and connected to drain
system.
