UNIT FEATURES
This premium unit has many features that
are different from 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 unit has an on board
computer that 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 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 such cases an “Fx” failure mode will be
displayed on the digital display. For a detailed list of all error codes and “Fx” conditions, see Table 6.
Status LED Indicator Definitions for further details.
• Memory – This unit also has memory, so if power is lost all of the control settings (set point,
mode, fan speed, on/off and configuration) are retained. When power is restored the unit will
start back up in the mode and configuration it was in when power was lost.
• Sound Reduction – The unit has 2 fan motors and a tangential blower wheel for noise reduction.
The indoor fan will start a minimum of 10 seconds before the compressor. This helps reduce compressor
noise on start up.
• Random Compressor Restart - To help prevent power surges after a power outage (occurs when many
PTACs start at the same time) the compressor is equipped with a 2:45 min. to 3:15 min. random
restart delay feature. When 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 for the compressor and a minimum compressor run time of 3 minutes.
•Automatic Room Freeze Protection – Keeps the temperature in a room above freezing where pipes might
freeze. If the unit is configured for the freeze protection feature to be active, (which is the default condition),
when power is applied to the unit and the unit senses temperature below 40°F the fan motor and electric
heater are turned on and will warm the room to 50 °F. If Freeze Protection is not required change the
configuration switch to turn the feature off (see section on unit configuration).
• Automatic Defrost Protection (for heat pump models only) – When the outdoor temperature gets
to approx. 35 °F and the unit can no longer effectively heat with the compressor, the unit will
automatically switch to electric heating. The unit will then heat with electric heat until the outside
temperature rises to approx. 40 °F then compressor can be used again.
• 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
for one cycle until heating set point is satisfied.
If the room temperature is less than 5°F from set point the compressor will be turned on in the heating function and
run until the room temperature is satisfied.
The electric strip heaters and the compressor will not operate simultaneously.
•LED Indicator’s and Buttons - The touch pad has buttons for MODE, FAN SPEED, ON/OFF,
SET POINT WARMER and SET POINT COOLER. It also has LEDs that correspond to the MODE,
FAN SPEED and SET POINT operation, to indicate the unit’s status. The LEDs below the MODE button,
FAN, COOL, and HEAT, indicate what operating mode is active. The LEDs below the FAN button, LOW,
MED and HI, indicate the fan speed that is selected. The LED located in the lower right corner is the unit
On/Off status LED. If the unit is in ON mode the LED will be green. If the unit is OFF, the LED will be red.
• 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 to disperse any residual heat or cool left on the coil.

UNIT FEATURES CONTINUED
• Unit Configuration – There are many different configuration possibilities, through both dip switches
and the digital keypad. This allows you to configure the unit for your exact application. See section on
unit configuration for more details. Following are the configuration selections that have not been previously
mentioned:
• °F or °C – The unit can display in either °F or °C.
• Indoor Temperature Sensor Biasing – Optimize the room temperature sensor reading to your exact
application (one for cooling and another for heating).
• Emergency Heat (for heat pump only) – Disables the compressor during heating mode operation and heats
with electric heat only.
• Display Set Point or Room Temperature - The unit can be configured to display the room temperature
or set point only during heating and cooling modes. See section on unit configuration for more details.
• Limit the Set Point Range - The unit can be configured to limit the controlling set point range. The
display will always show the complete set point range but the controlling set point will be limited to the
configured minimum and maximum set point 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 24 VAC on this input it will
turn itself off. If no voltage is detected on the input the unit will run normally.
• Wall Thermostat Control - An external wall thermostat can be connected to the unit. If connected the
unit must be configured to disable the keypad. See section on wired inputs and unit configuration for
more details.
• Remote Control - Remote control is available by adding a receiver module to the unit. See the 950-0254
installation manual packaged with the remote control and receiver module.

INSTALLATION
Proper installation is the responsibility of the installer. Product failure due to improper installation is not
covered under warranty.
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended that a
Sea Breeze sleeve be used.
The unit will fit 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).
!
CAUTION
UNIT DAMAGE AND/OR OPERATION HAZARD
Failure to follow this caution may result in equipment
damage or improper operation of unit.
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 major
components may result.

INSTALLATION OF A CARRIER WALL
SLEEVE USING A NON CARRIER
GRILLE
This application has become more common due to pre-manufactured windows with built-in grilles or
renovations where a Carrier sleeve is used with an existing non-Carrier grille.
Use of a Carrier wall sleeve with a non-Carrier grille requires installation of an Accessory Baffle Kit (see
Fig. 8), which ensures a good seal between the unit and exterior grille to prevent air recirculation. Air
recirculation is a large contributor to performance loss and premature damage to major components.

front desk control Input must be 24VAC. If the system receives a 24 VAC signal, it will turn unit off.
Otherwise the unit runs in normal mode. This function will be disabled under Freeze Guard protection.
See Fig. 24 and Fig. 25 for terminal connections.
INTELLIGENT SELF-CHECKING CONTROL
Your PTAC has a computer board that continuously monitors key components of the unit to ensure they are
operating properly. Under normal operation unit status indicator (STATUS, on main PCB) light is steadily
ON.
lf there is a major problem the unit will shut down and display a diagnostic failure code on the unit 's
display. If it is only a minor failure and unit will try to correct the fault. The diagnostic code will be flashed
on the status LED that can easily be seen when the front panel is removed (See Fig. 24). Failure STATUS
codes are defined in the table below.

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.
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). Check base pan periodically and clean, if necessary.
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.
!
The most important thing you can do to maintain unit efficiency is to clean the filters at least every 30 days
(or sooner depending on conditions). 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.
