You can recharge any type of AC unit. First you must find out where the leak was and repair it. Then you need to pressure check it with nitrogen and leak check it to make sure there are no more leaks. You'll then need to pull a vacuum of 30 inches of water and then charge the unit with the safe refrigerant that came out.
Under normal conditions, refrigerant or freon need not be recharged or replenished. Refrigerant is contained in a "closed loop" that consists of a compressor, expansion valve, evaporator coil and condenser coil. If a leak developes as a result of damage to any of these components, the refrigerant will escape as it is under pressure. The leak will need to be located and repaired before refrigerant can be returned to the system. An unsufficent refrigerant level is always an indication of a leaking system, but; an A/C unit that fails to cool the air is not always a sign of a low refrigerant level.
Sadly the company is out of business, so you will have to get a little creative like I did. I got what I needed at lowes, some flex duct, a pvc pipe fitting, small metal brackets, zip ties, thick foil tape, a piece of plywood for the window part, and some paint. Good luck.
the bottom blower in a PAC9 is the blower motor that sucks room air in through the bottom vents of the unit through the condenser. this air removes heat from the condeser and is blown out through the warm air vent duct. A common failure on windchaser units is the 'bottom blower squirrel cage' which is a plastic fanblade.
I had similar problem .... on very humid days unit leaks ..... temp solution for me was to drain the unit .... inserted wire coat hanger into tube .... lots of watery gook came out.. - even tilted/tipped the unit inorder to get as much water out of it.......afterwards unit worked fine.
We are VERY SASTIFIED with the Delonghi Pinguino - bought it years ago when it first came out and it has provided years of troublefree service .... the water build up / leaking was only recently - in fact we never drained the thing until this year.
when tank is full you will get the letters FE will signal a FULL TANK (The tank is full)
You have it setup to constantly drain GOOD. Should you should not plug the drain hoses to get colder air. Do let it drain . It is more convenient! If the unit is the proper BTU for the square footage of the area to be cooled it will be cold! If the tank gets full you will not get cool air?
