This unit has many exciting features which 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.
Dry Mode -- For increased comfort and humidity management, an added “Dry Mode” is standard on all Frigidaire PTAC’s. This mode feature will help manage and reduce the humidity content within the living space, making it more comfortable. In DRY mode, the unit will modulate cooling mode at low fan speed until the room temperature is 4° F below the room temperature setting regardless of fan mode selection. Dry mode should not be considered a substitute for a standalone dehumidifier. In “dry mode” more condensation will be created and the use of a “drain kit” (5304480570) is recommended.
Intelligence -- Your 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 faulty 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 of all error codes and “Fx” conditions. see Table 5 (page12) Status LED Indicator Definitions for further details.
Memory -- Your 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.
Quiet Design -- Not only does the unit have 2 fan motors and a tangential blower wheel for optimum sound. the indoor fan will always run a minimum of 10 seconds before the compressor. to help reduce the sound of the compressor starting.
Random Compressor Restart -- To help prevent power surges after a power outage (many PTACs starting at the same time). the compressor is equipped with a 2 minutes 45 seconds to 3 minutes 15 seconds random restart delay feature. Whenever the unit is plugged in. or power has been restarted. a random compressor restart will occur to help avoid power surges.
Automatic Room Freeze Protection -- This protection feature will automatically ensure the indoor temperature does not fall below freezing. When your PTAC is configured for freeze protection (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°F. Freeze protection can be switched off (please see page 9). 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 for one cycle. until room temperature rises.
Dual-8 Display and LED Display -- Two 8-segment nixie tubes. 13 LED indicators (They are HIGH, MED, LOW, AUTO, COOL, FAN, HEAT, ON/OFF, SETPOINT, INDOOR, STATUS and TIMER)
Fan Configure for Optimization of Selected Application -- The 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. the fan will continue to run after the compressor or electric heater stops in order to blow off any residual heat or cool left on coil.
Fan Motors-Permanently Lubricated -- The unit have two fan motors for quiet operation and maximum operating efficiency. Motors are permanently lubricated to reduce maintenance and totally enclosed to keep dirt and water out of the motor windings.
Outdoor Fan -- The unit automatically selects the most efficient speed for the outdoor fan. The operating sound level is lower when the outdoor fan can operate in low speed yet there are situations where it must operate in high speed. The unit changes the fan speed automatically.
Indoor Fan Speed Selections-HIGH/LOW -- The unit automatically selects the most efficient speed for the outdoor fan. The operating sound level is lower when the outdoor fan can operate in low speed yet there are situations where it must operate in high speed. The unit changes the fan speed automatically.

• Check dipswitch settings for desired comfort.
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.
DISPLAY HAS STRANGE NUMBERS/CHARACTERS ON IT
• The unit may be in a diagnostic condition. Check Intelligent SelfChecking Control section to determine if unit has had a failure. •The unit may be set for °C(instead of °F), see the keypad configuration section
WATER DRIPPING OUTSIDE
• 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 INSIDE
•Wall sleeve is not installed level
• 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.
• 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:
If circuit breaker is tripped or fuse is blown more than once, contact a qualified electrician.
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.
