Two capacity figures and an inverter compressor
Whynter rates the ARC-1230WN at 14,000 BTU under ASHRAE and 12,000 BTU SACC, and claims it cools up to 600 square feet. Both numbers appear on Whynter's page and the listing, each under its own rating standard. Treat 600 square feet as a maker claim with no stated room conditions.
Whynter describes it as an inverter unit, and its page puts the estimated energy saving at 40 to 50 percent; the listing's bullet says 40 percent. None of these figures come with test conditions, and we did not measure anything. Whynter's page lists CEER 13.8 and EER 10.8, while the listing's table shows 12.3, labelled as SEER.
Other maker figures: R-32 refrigerant, 1,293 watts and 11.9 amps, 115 volts at 60 Hz, a 60 to 86 degree Fahrenheit thermostat, 87 pints a day of dehumidifying, noise of 42.5, 49.5 and 56.5 dB on low, medium and high fan, and airflow of 225, 244 and 388 CFM. The unit measures 19.5 by 16.75 by 32.5 inches and weighs 77.25 pounds.
Hose-in-hose venting and the window kit
Whynter's product page address calls it a dual-hose unit, and its specifications describe a single hose-in-hose assembly. It extends to 47 inches. The manual says not to overextend or bend it, to keep the exhaust hose as short as possible, and to leave 20 inches clear around the exhaust outlet.
The hose and window adapter are required in Cool mode. In Fan or Dry mode the manual says they can be removed. The window kit is three sliders, 9.5 inches wide and adjustable from 28 to 82 inches; if your window is shorter than one slider, the manual says to cut the slider that has the hole, from the other end, and never cut the end with the hole.
In the box, according to the manual's parts list: the hose-in-hose set, three window sliders, an air outlet adapter, two each of foam seals A and B plus one seal C, a security bracket, two bolts, a drain hose adaptor, the remote with two AAA batteries, and a washable filter and carbon filter already fitted.
Thirty-six inches of clearance and its own outlet
The manual's safety list asks for at least 36 inches of clearance around the unit and for it to be kept clear of combustible items. Its installation page adds that the unit should sit at least 9.8 inches (25 cm) from the nearest wall and the louver at least 19.7 inches (50 cm) from obstacles, with the drain accessible.
Power rules are strict. Use a properly grounded wall outlet, protected by a time-delay fuse or circuit breaker sized to the nameplate current, and do not share a single outlet with other appliances. Do not modify the cord's length or use an extension cord. The plug has a current-detection device with TEST and RESET buttons; the manual says not to use it as an on-off switch and never to bypass the ground prong.
It is not for bathrooms, laundry rooms or other wet rooms, and its wheels should not be used on thick carpet. R-32 is a flammable refrigerant, so the manual asks that the unit be stored in a room without continuously operating ignition sources, and that refrigerant-circuit work be left to certified technicians.
Modes, sleep, and a remote that doubles as a thermostat
The mode button cycles Auto, Cool, Dry and Fan, which matches Whynter's four-mode spec; the listing's bullets describe only three. In Auto you cannot choose the fan speed, and in Dry the settings are fixed. Fan speeds are Low, Medium, High and Auto, and the manual lists a continuous-fan option in Cool or Dry.
Sleep mode works only in Cool: after 30 minutes it raises the set temperature by one to two degrees, and the manual gives it a seven-hour run. The timer can schedule an on or off time from 0 to 24 hours. The unit restarts on its previous settings after a power cut, and the compressor has a three-minute restart delay.
The remote's I Sense feature makes it act as the thermostat, sending the temperature where you are every three minutes from up to 26 feet away; it does not work in Dry or Fan mode. Wi-Fi control uses the NetHome Plus app, and Whynter's page lists Alexa and Google Home voice control. A filter light comes on after 250 hours of running.
Draining, P1 and the operating range
Whynter lists a self-evaporation feature, but the manual still covers draining. When the internal pan is full the unit beeps eight times, shows P1, and stops cooling or dehumidifying while the fan may keep running. The manual describes emptying through the bottom drain plug, and a continuous gravity drain from the upper port with the supplied hose during Dry mode.
The troubleshooting table suggests setting the temperature at least five degrees below the room and, when P1 appears, either draining manually or running fan-only mode. Error codes E1 to E4 point to sensor faults, and the manual's troubleshooting table is where to look them up before contacting Whynter.
Whynter's own manual gives two operating ranges. One page gives an operating ambient range of 60 to 95 degrees Fahrenheit; the troubleshooting table says it is designed to work between 63 and 90 degrees. The two figures are not reconciled in the manual.
Filters, storage and a warranty with conditions
The washable pre-filter should be cleaned every two weeks, and the manual limits rinse water to 100 degrees Fahrenheit. It gives two intervals for replacing the activated carbon filter on the same page: every three to six months in one place and every two to three months in another. The manual does not say which interval applies, so ask Whynter before you plan replacements.
For end-of-season storage the manual's routine includes draining the unit fully and drying the inside on Fan mode before storing it somewhere cool and dark. It also says to transport the unit upright.
The warranty is one year against defects in materials and workmanship, plus two more years on the compressor, which matches the three-year compressor term on Whynter's page and the listing. It applies only to the original owner who bought from an authorised Whynter dealer in the 48 continental states, needs a Return Authorization number, is mail-in, is not transferable, and after the first two months you pay return freight. Products sold as-is or by unauthorised resellers are excluded.
