PAC L90 leaking oily substance

My PAC L90 was blowing air, like a fan, but not cold air so I decided to open it up. I found that there was a crack in a 1/4 inch copper pipe that connects the compresor to what looks like a radiator. There was an oily substance that leaked out - and there was alot of it. I mended the break by adding a 3/8 inch copper pipe that was about an inch long and sweat them together. After doing so, the problem still remained. I assume that whatever the oily substance was, it needs to be replenished. Can someone please tell me what this oily substance is and if I can replenish it myself (if possible) or if I can take it to someone to rpelenish it? Thanks.

It leaked all the freon and oil out .
it needs to be vacuumed and oil replenished.
filled with freon.
should only cost you bout 50.give or take
as they use very little freon.
a shrader valve port has to be added to introduce the freon. takes just a few seconds.

PAC L90 air conditioner keeps frosting up. The room air intake frosts up completely, blocking all the air.


Air conditioners frost up when there is a lack of air flow. Clean the filter, check if a belt is broken (if any), check that the fan spins freely, check all in ports and out ports for blockage and clean the coils with mild soap and water.

If you need gas then first you have to find the leak. There will be tap valves it introduce gas into the system but some makers just seal off the pipe requiring any re-gassing to be done by an air conditioner specialist.

PAC L90 water tank capacity


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?


Please remember to leave a rating before you go!
Thank you

Delonghi Pac L90


Hoses for proper connection should have been included with your purchase. Without the hoses the set-up can not be done satisfactory. One is for fresh air supply and the other is the hot air exit hose. These are normally vented out a window. Check with the dealer where you perchased the unit from. If from a private individual contact them.
