Hello, nice to meet you! (^o^) Since it doesn't use gas, you can use it immediately by plugging it into an outlet. Recommended for rooms where gas cannot be used ✨ Sharp Plasma Cluster Humidifying Ceramic Fan Heater White HX-G120-W Made in 2018 6-tatami mat model (approx. 9.7 square meters) No instruction manual, everything is as shown in the photos. It has been cleaned, so you can use it right away and feel good about it ✨ As you can see in the photos, there is little calcium (chlorine) buildup on the humidifying filter, and the filter is still in good condition. If you are concerned about the filter, you can buy it cheaply on Mercari, so I recommend purchasing it there. Please use tap water for the water in the tank. Using purified water because you dislike calcium buildup can cause mold and slime. As shown in the second photo, I measured the warm air at over 50 degrees Celsius even from a distance. There are no unpleasant odors or burning smells, and the condition is good (^o^) It doesn't seem like there is any dust inside or a decrease in the performance of the fan, and warm air came out strongly ✨ There are some minor scratches that don't show up in the photos, but there are no noticeable scratches, and the condition is good. I have taken photos of everything, so please take a look and consider purchasing it m(_ _)m ✨ [Genre] Ceramic Heater Sharp (SHARP) [Product Description] Sharp Plasma Cluster Humidifying Ceramic Fan Heater White HX-G120-W 6 tatami mats (approx. 9.7 square meters) Humidification capacity: 540/520mL/h (50/60Hz) Power consumption: Maximum approx. 1200W Plasma Cluster applicable floor area (approx.): 6 tatami mats (approx. 9.7 square meters) Tank capacity: approx. 2.7L Power cord length: approx. 1.8m It has been cleaned, so you can use it right away ➰ Sharp Humidifying Fan Heater Type...
