The Whynter Elite 14,000 BTU Portable Air Conditioner with 3M Filter, model ARC-143MX, is designed to provide cooling, dehumidifying, and fan-only operation for residential use. This portable air conditioner is equipped with caster wheels for easy mobility and is intended for use on hard, level surfaces.
Function Description:
The primary function of this unit is to cool and dehumidify a room. In cooling mode, the air conditioner extracts hot air from the room and exhausts it outside through a dedicated exhaust hose. An optional intake hose can also be used. The unit also features a dehumidifying mode, where it primarily removes moisture from the air, with the compressor activating intermittently. The fan speed is set to low in this mode, though it can be adjusted if the room temperature is above 77°F. The exhaust hose is optional in dehumidifying mode; if not vented, more frequent draining may be required. In fan-only mode, the unit circulates air without cooling or dehumidifying, and the exhaust hose is not required.
The air conditioner includes a control panel and a remote control for operation. The control panel features an LCD display, power control, mode control (Cooling, Dehumidify, Fan only), timer/temperature set control, and fan speed control (High, Medium, Low). The timer function allows for delayed switch ON or OFF, adjustable between 1-24 hours. The unit also has an auto-restart feature, which restores previous settings after a power outage.
A key feature is its self-evaporating function, which automatically exhausts most condensation in environments with less than 70% humidity. In higher humidity conditions (above 70%), about 98% of moisture is still exhausted, with the remaining 2% collected in an internal water tank. A warning light and STOP light will illuminate, and the unit will cease operation when the internal reservoir is full, indicating the need for manual drainage.

Maintenance Features:
- Air Filters: Equipped with a washable Pre-Filter and a 3M™ Antimicrobial High Air Flow (HAF) Air Filter.
- The Pre-Filter removes large particles like dust and pet hair and should be washed every two weeks.
- The 3M™ Antimicrobial HAF Air Filter is frameless, self-supporting, and helps inhibit mold and mildew growth. It is not washable and should be replaced every 3 months.
- The unit should never be operated without the Pre-Filter.
- Cleaning:
- Always switch off and unplug the unit before cleaning.
- Wipe the body with a soft, damp cloth. Avoid harsh chemicals, oil-based products, or abrasive cleaners.
- Water Drainage:
- Manual drainage is required when the internal water reservoir is full. This involves turning off the unit, positioning a container under the drain port, and removing the drain cover and rubber plug.
- For end-of-season storage, all condensed water must be completely drained.
- End of Season Storage:
- Includes a storage cover to protect the unit when not in use.
- Before storage, clean the pre-filter, drain all water, run the unit in Fan only mode for half a day to dry internally, remove batteries from the remote, and disconnect hoses from the window kit (if applicable).
- Internal Cleaning: Recommended annually; contact Whynter for instructions.
