Important Technical Specifications

Voltage Measurements:
- For 230/280V units, the voltage utilization range is 187V (minimum) to 253V (maximum).
- For 115V units, the voltage utilization range is 103V (minimum) to 126V (maximum).
- It is crucial to measure the supply voltage before connecting the unit to ensure it falls within these ranges.
Compressor: The unit is equipped with a rubber-grommet-mounted compressor, which is factory set and requires no adjustment. The compressor is hermetically sealed, permanently lubricated, and requires no additional oiling.
Power Cords: The unit may feature LCDI (Leakage Current Detection and Interruption) or AFCI (Arc Fault Circuit Interruption) power cords, which sense current leakage and can open the electrical circuit. If the unit does not operate, checking the reset button on the power cord is part of the normal troubleshooting.
Power Plug Types: The manual illustrates three types of acceptable power plugs: 120V 15 Amp, 240V 13 Amp, and 240V 18 Amp. Users must check the data specification plate to ensure the proper voltage and current rating are available for their unit's power plug.
Vent Control: The vent control allows for air circulation (CLOSE position) or exhausting some inside air outside (OPEN position).
Temperature Range: The control maintains any set temperature between 61°F (16°C) and 86°F (30°C) for both cooling and heating modes.
Timer Setting Range: The timer can be set for 0.5 to 24 hours, with increments of 0.5 hours up to 10 hours, and then 1 hour increments up to 24 hours.
Filter Reminder: An LED will light up on the user interface after 250 hours of accumulated fan run time, reminding the user to clean the filter. This feature can be enabled or disabled via a DIP switch.
Remote Thermostat Compatibility: The unit can operate with a Class 2 Remote Control Wall Thermostat if enabled via a DIP switch and if the Thermostat Control Conversion Kit (PBTCK01) is purchased and installed.

Usage Features

Operating Modes: The unit offers various operating modes, including AUTO, COOL, DRY, FAN, and HEAT (for models with heating function).
Temperature Adjustment: Users can increase or decrease the set temperature in 1°F (°C) increments using the "+" or "-" buttons on the control panel or remote. Holding the buttons for 2 seconds allows for rapid temperature changes.
Fan Speed Control: Fan speed can be adjusted circularly through AUTO, SPEED 1, SPEED 2, SPEED 3, and SPEED 4. In AUTO speed, the air conditioner automatically selects the appropriate fan speed based on ambient temperature. Fan speed cannot be adjusted in DRY mode.
Sleep Function: Available in COOL, HEAT, and DRY modes, the Sleep function can be turned on or off. It is unavailable in FAN and AUTO modes.
Timer Function: The unit features a timer-delay start/stop feature. Users can set a Timer Off when the unit is on, or a Timer On when the unit is off. The timer can be adjusted in 0.5-hour increments up to 10 hours, and then 1-hour increments up to 24 hours. The timer function can be canceled by pressing the TIMER button again after reviewing the remaining time.
Air Direction: Horizontal louvers on the front grille allow users to control the air direction up and down. Vertical louvers can be adjusted side-to-side by removing the front grille.
Child Lock Function: Pressing "+" and "-" buttons simultaneously on the remote control can activate or deactivate the child lock, preventing unintended operation.
Temperature Display Switchover: Under OFF status, pressing "-" and "MODE" buttons simultaneously can switch the temperature display between °C and °F.
Remote Control Operation: The remote control duplicates all functions of the touch pad. It requires line-of-sight operation with the indoor unit's receiving window, with a maximum distance of 8m and no obstacles.

Maintenance Features

Filter Cleaning: The filter can be removed for cleaning. The unit has a filter reminder function that activates after 250 hours of fan operation.
Front Panel and Grille Cleaning: The front panel and grille can be cleaned with mild soap or detergent. Avoid hydrocarbon-based cleaners.
Outdoor Coil Cleaning: The coils on the outdoor side should be checked regularly. For cleaning, the 6 screws mounting the condenser coil top cover to the condenser shroud must be removed.
Periodic Cleaning/Inspection: To maintain top performance and efficiency, a regular cleaning/inspection schedule should be established. This includes removing the unit from its sleeve to thoroughly clean the basepan and condenser coil, especially in dusty climates.
Corrosion Protection: If the unit is installed in a corrosive atmosphere (e.g., ocean side), it should be removed from the sleeve and completely cleaned once a year. Any scratches or blisters on painted surfaces should be sanded and repainted.
Battery Replacement: New batteries of the same model should be used when replacement is required for the remote control. If the remote control display is fuzzy or blank, replace the batteries. Remove batteries if the remote control will not be used for a long time.
