UNIT FEATURES

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.

Total Corrosion© Protection -- All Frigidaire PTAC's come standard with anti-corrosion protection, to increase system and component durability in standard applications and protect system and components in Coastal areas where Air sea salt content is higher than standard applications. All coils are treated with a dual hydrophilic coating, and an added hydrophilic coating for all connecting plates. Standard materials have been replaced with stainless steel for critical components such as hardware, condenser side panel, compressor hardware and Condenser fan hardware. Special anti-corrosion paint is used on the drain pan to ensure the integrity of unit mounts to the chassis.

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 prong 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 - 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 for optimistic 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 automatic ensure the indoor temperature does not fall below freezing. When your PTAC is configured for freezer 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, change the configuration switch to turn the feature off.

Automatic Quick Warm-Up (for heat pump models only) - If the room temperature falls to 5°F blow 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 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.

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 annually. 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, coil should be professionally cleaned. Under extreme conditions, more frequent cleanings may be required.

Clean the coils and basepan with a soft brush and compressed air or vacuum. A pressure washer may also be used, but be aware that the aluminium fins must not be bent. Use a gental up and down motion in the direction of the vertical aluminium fins when pressure washing coils.

CAUTION: UNIT DAMAGE HAZARD

  • Product failure due to improper care or lack of maintenance is not covered by warranty.
  • Airflow restriction may cause damage to the unit.

BASE PAN

Check base pan periodically and clean, if necessary.

AIR FILTERS

IMPORTANT: TURN UNIT OFF BEFORE CLEANING

CAUTION: UNIT DAMAGE HAZARD

  • Product failure due to improper care or lack of maintenance is not covered by warranty.
  • 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.

To maintain unit efficiency 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.
