Before operating your Whynter ARC-14SH, carefully unpack all components and verify everything listed in the component checklist is present. Ensure the unit is placed on a level surface, allowing sufficient space around the unit for proper ventilation – at least 16 inches clearance is recommended.
Connect the power cord to a grounded outlet, confirming it meets the specified power requirements. It’s vital to keep this manual for future reference. Allow the unit to stand upright for at least two hours before initial use, enabling the refrigerant to settle.

Familiarize yourself with the control panel and its functions. Before starting, inspect the unit for any visible damage incurred during shipping. If damage is present, do not operate the unit and contact customer support immediately. Following these instructions will ensure optimal performance and longevity of your new Whynter portable air conditioner.
Window Kit Installation Guide
Proper window kit installation is crucial for efficient operation of your Whynter ARC-14SH. Begin by selecting a suitable window – a double-hung or sliding window is ideal. Adjust the window kit panels to match the window opening’s width, ensuring a snug fit.

Securely attach the panels using the provided screws, creating a sealed enclosure. The window kit is designed to prevent outside air from re-entering the room. Carefully follow the instructions to avoid gaps.

Once the kit is installed, connect the exhaust hose to the designated port on the window kit and the unit itself. Ensure a tight connection to maximize cooling efficiency. Regularly inspect the window kit for any signs of loosening or damage, maintaining optimal performance of your Whynter portable air conditioner.
Exhaust Hose Connection
Correctly connecting the exhaust hose is vital for the Whynter ARC-14SH’s cooling performance; First, ensure the hose is fully extended to its maximum length. Attach one end securely to the exhaust port on the back of the air conditioner unit, twisting clockwise until locked.
Next, connect the other end of the hose to the window kit, again ensuring a tight, clockwise twist-lock connection. Any gaps or loose fittings will significantly reduce cooling efficiency.

Periodically check the hose for kinks or obstructions, as these can restrict airflow. Avoid excessively bending the hose, as this can damage it. Proper hose connection, as detailed in this manual, guarantees optimal operation of your Whynter portable AC.
Operating the ARC-14SH
This section details how to effectively use your Whynter ARC-14SH, covering the control panel, cooling functions, and heating mode operation for optimal comfort.
Control Panel Overview
The Whynter ARC-14SH control panel features intuitive buttons for effortless operation. The power button initiates or terminates the unit’s functionality. Temperature adjustment is achieved using the “+” and “-” buttons, allowing settings between 61°F and 89°F. A mode selection button cycles through cooling, heating, and fan-only modes.
The fan speed can be adjusted to three levels: low, medium, and high, providing customized airflow. A timer function enables pre-set operation durations for convenience. The display panel clearly indicates the selected mode, temperature setting, and timer status. Additionally, an indicator light alerts users when the water tank requires drainage. Familiarizing yourself with these controls ensures efficient and personalized climate control with your Whynter portable air conditioner.
Cooling Mode Operation
To initiate cooling, ensure the Whynter ARC-14SH is properly set up with the exhaust hose connected and window kit installed. Press the “Mode” button on the control panel until the cooling icon illuminates. Utilize the “+” and “-” buttons to select your desired temperature, ranging from 61°F to 89°F.
Adjust the fan speed – low, medium, or high – to customize airflow intensity. The unit will automatically begin cooling the room to the set temperature. Monitor the water tank indicator; when full, drainage is required to maintain optimal cooling performance. For efficient operation, close windows and doors to prevent warm air from entering. The auto-restart function will resume operation after a power outage, retaining your previous settings.
Heating Mode Operation
Activate heating mode on your Whynter ARC-14SH by pressing the “Mode” button until the heating icon is displayed on the control panel. Similar to cooling, use the “+” and “-” buttons to set your preferred temperature, within the range of 61°F to 89°F. Select a fan speed – low, medium, or high – to control the heat distribution.
The unit will then begin warming the room. Note that the unit may cycle on and off to maintain the set temperature. Ensure proper ventilation and avoid obstructing the air intake or exhaust. Regularly check the water tank, as condensation may occur during heating. The auto-restart feature will restore your settings after a power interruption, ensuring consistent heating.
Maintenance and Troubleshooting
Regular filter cleaning and proper drainage are crucial for optimal Whynter ARC-14SH performance; this section details solutions for common operational issues.

Filter Cleaning and Replacement
Maintaining a clean air filter is paramount for efficient operation and air quality with your Whynter ARC-14SH. The filter captures dust, allergens, and other particles, preventing them from circulating within your space. Regularly inspect the filter – ideally every two weeks during periods of frequent use – for accumulated debris.
To clean the filter, gently remove it from its housing. You can then vacuum the filter to remove loose dust. For a more thorough cleaning, wash the filter with mild soap and lukewarm water. Ensure the filter is completely dry before reinstalling it to prevent mold or mildew growth.
Replacement is necessary when the filter becomes damaged or excessively dirty and cannot be adequately cleaned. Whynter recommends replacing the filter every three to six months, depending on usage conditions. A clogged filter restricts airflow, reducing cooling and heating performance and potentially causing the unit to overheat. Refer to the manual for the correct filter model number when ordering a replacement.
Drainage Procedures

The Whynter ARC-14SH generates condensate during cooling mode, which must be properly drained to ensure optimal performance and prevent water damage. This unit features both continuous drainage and internal tank options. For continuous drainage, connect a hose to the drain port on the back of the unit and direct it to a suitable drain location.
If utilizing the internal tank, the unit will automatically shut off when the tank is full, and an indicator light will illuminate. Carefully remove the tank, empty it, and reinsert it securely to resume operation. Avoid tilting the unit excessively when the tank is full to prevent spillage.
Regularly check the water level in the tank, especially during humid conditions. Whynter recommends emptying the tank before storing the unit to prevent stagnant water and potential mold growth. Always disconnect the unit from the power source before performing any drainage procedures.
Common Issues and Solutions
Whynter ARC-14SH users may encounter a few common issues. If the unit isn’t cooling effectively, ensure the air filter is clean and the exhaust hose is properly connected and not kinked. A frozen evaporator coil can occur in cooling mode at low temperatures; try increasing the temperature setting or using fan-only mode to defrost.
If the unit shuts off unexpectedly, check if the water tank is full or if there’s a power interruption. Error codes displayed on the control panel indicate specific problems – consult the manual for their meanings. Unusual noises might stem from loose components; ensure everything is securely fastened.
For persistent issues, disconnect the unit and contact Whynter customer support. Avoid attempting repairs yourself, as this could void the warranty. Regular maintenance, as outlined in this manual, can prevent many of these problems.
