Air gets warm and smells. No water coming out underneath.
Hi. we have the above air conditioner and cannot find out how to open the vents underneath to let the water out. What this air conditioner does is it starts off great, after a couple of hours it does not cool as much and after that there is a musty smell in the room. When we take the air conditioner out, it leaks water all over the floor.
Also, it has a dry setting. What does this do? It does not mention this in the book we received with the air conditioner.
I appreciate any help you can give us.

Re: Air gets warm and smells. No water coming out...
FIRST THERE IS NO SWITCH TO LET THE WATER OUT, THE WATER IS LET OUT OF THE EVAPORATOR SECTION THREW A SMALL HOLE LOCATED INSIDE THE BLOWER SECTION TO THE BOTTOM LEFT IT GOES THREW THE BED PLATE AND OUT THE BACK OF THE UNIT.MY GUESS IF YOU HAVE STANDING WATER IS THAT THE UNIT IS NOT PITCHED PROPPERLY IN THE OPENING. IT SHOULD BE PITCHED DOWN IN THE BACK AND SLIGHT RIGHT IF YOUR LOOKING AT THE FRONT OF THE UNIT. HOPE THIS HELPS.
PS THE DRY SETTING PROBABLY REFERS TO USING YOUR ELECTRIC HEAT STRIP AS A DEHUMIDIFIER TO RUN WHILE YOUR IN THE COOLING MODE BUT IM NOT SURE.

Not all of your question was view-able, but sounds like your drain tube may be plugged if you are getting musty smells. Inspect the drain tube for clogging (lower right of unit). Pour a glass of water over the metal fins and watch to make sure it drains correctly down and out the tube. Look outside or at the far end where it drains and be sure water comes out. If not, try a bristle brush style pipe cleaner wire to insert and clean the opening. Once its draining well, you should use a mild bleach solution and spray bottle to hose down the entire inside heat exchanger. Never put anything into/between the metal fins except cleaning fluid. Using a brush on the fins will mostly just push the dust back and compact it so the water can't dislodge it. After a good cleaning, it will help to run just the fan or heat mode for a while so the vents dry before using cooling mode.
You should look in the air handler( Where the indoor blower is located) or in the plenum (where the duct system originate at the air handler) for any dead and rotting rats. Residential central air systems are sealed (uses circulated air only) and do not use outdoor air.
Hello - Some air conditioner filters are removed by sliding out from the right-hand side. Others, you need to push the vent handle to the Vent Closed position and open the front panel. Grasp the filter by center and pull up and out the filter can be wash using liquid dishwashing detergent and warm water. Rinse filter thoroughly. Gently shake excess water from the filter. Be sure filter is thoroughly dry before replacing. Keep in mind that instead of washing you may vacuum the filter clean as well.
if it's the air vent you'll notice a different sound as well air pressure from inside to outside air. if it's the drain vent you'll see water flowing outside the unit. this is the condensation that forms
Check the air conditioner fuse and replace as necessary.
Air conditioner system discharged.
Have the system evacuated, charged and leak tested by an MVAC
certified technician, utilizing approved recovery/recycling equipment.
Repair as necessary.
Air conditioner low pressure switch defective. Replace switch.
Air conditioner fan resistor pack defective. Replace resistor pack.
Loose connection, broken wiring or
defective air conditioner relay in air conditioning electrical
circuit. Repair wiring or replace relay as necessary.
Air conditioner has a smell when used
The air conditioner evaporator
drain hose is blocked or partially restricted, allowing condensation
to build up around the evaporator and drainage tray. Clear the drain
hose where it exits the passenger compartment.
Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.
It sounds to me if you are having a "musty smell" then you might have a problem with your condensation drain line for you a/c system or a small leak on your heater core. If it is plugged then water will collect in the vent system causing a musty smell from the water not draining and if there is a small leak on the heater core then coolant can collect in the vent system. I would run the a/c on a warm day and look for water draining from the vehicle around where the dash is located to check the drain line. As far as your air cabin filter most are located behind the glove box. You usually need to remove the glove box to get to the filter.
The fan that blows the air blows through the heater coils before it blows through the A/C.As long as the heater doesn't come on, there is not much that can be done. ZCooking the attic room will be a problem because it is the heat rises thing, and on top(literally) of it all, the roof is radiating heat.
3 places where water could be coming from, The Ground, The venting system or the Condensate. Eliminate each one by first checking the condensate piping and check to make sure it is draining to the drain. Blow thru all hoses to make sure they are not blocked. Secondly, spray with a garden hose the venting system to see if the water is entering the system thru the venting. Lastly, if this happens only when it rains, you could have a ground water drainage issue.
