WATER COMING THROUG FRONT OF FUJITSU fan coil unit
Unit was just cleaned a week ago, located in a computer room customer had the room set for 64 deg, SA temp is 43 deg, other unit had 62 deg SA temp, charged to 53 deg SA, only changes have been getting old unit to run colder.
Raised temp setting to 68 deg, & took fan out of Auto & put to Med Speed. Had unit off & covered with sheet then blew Co2 from outside drain line & draining fine. Water still seams to be leaking in off front louver on Med Speed.

You first need to pull it out of the window Then, take off the case which will require removing several screws and the "wings" that make it fit in the window. Set it on the concrete or a sturdy outdoor table The rear and front coils will be the most important things to clean. Water is the best way to clean, but it you use a hose and sprayer, you have to be careful not to get the electrical components wet. You can also use a good vacuum cleaner if you have one that has a wand. The rear coil can be loosed from the fan shroud by just a few screws and set back to where you can get to the rear of the coil. It will be stopped up with dirt,etc. Take the vacuum or water sprayer and clean rear coil thoroughly. The front coil can be cleaned from the front. A wire brush would help you out greatly. Be sure to clean out the bottom pan of the air cond also, so that the unit will be free to drain properly. Be sure, if you loose the rear coil from the fan shroud not to bend the tubing coming from the coil. Also if you are using water, let the unit dry out for an hour or so before you plug it back in.
Remove the window unit and dissasemble,and clean it out,careful not to bend the fins on the condense and evaporator,but clean them out,and the inside of the unit also,then see what happens,if the problem persist,then find the probe on the evaporator and move it away from the evaporator until the compressor stays on longer.
Wash out outside coil from time to time.This is the most over looked part of window units. Take care not to spray water directly into fan motor. If not real humid in house check temp coming out of ac inside and make sure filter and coil are clean. run on high speed and the air should have good force. 20 to 30 degree temp drop of room temp should be about right. Much depend on outside temp and humidity and indoor humidity plus insulation factor of area. How many people are in the area and if you keep unit on day and night .
there are coils in the unit that the water folws across, you can take the filter out and clean the coils, this would help,but even though it is only 1 year old it can go bad,, if it is clean inside and everything is appering to be working it might have just gone bad and n eed a new one
On the outdoor unit the fan should not be running, on the indoor unit the fan should be running. If you then check the outdoor unit with fan not running, you should be able to hear clearly that the compressor is actually working. If this is all correct, it is possible that your fourway reverse valve is seeping and needs to be replaced.
Hi, If this is a new unit I would check the filter first and make sure it is clean. Also check and make sure it is slightly tilted to the outside. If its an older unit it probably needs cleaned. Window units naturally create water in the evaporator area. The water is suppose to drain to the back of the unit to the condensing area where the slinger ring on the condenser fan blade slings it into the condenser coil making it more efficient. There is usually a drain hole to drain excess water from the back of the unit. Any dirt in the pathway of this water or the wrong tilt will cause water to build up and drip or blow out the front. Anything touching the evaporator coil allowing water to run down the obstacle into the wrong area will cause the same thing. reduced air flow will cause the evap to freeze which could also cause a water problem.
