Pump down the gas.: Start the unit let it run for 5 minutes after compressor start working. In out door unit first close completely liquid line valve (Discharge line) and after 5 seconds switch of your unit ( Most important). Now close suction valve. Pump down completed. Helpful?

How do I disconnect a Delonghi Super Penguino split system portable air conditioner exterior unit?


Time for a service call. You just released some of the freon in your system and now it's not charged correctly. Thank god nobody got poisoned. Have the tech reclaim the refrigerant you have left and disconnect the hard lines and electricity. Do your project, then call the tech back to connect, recharge and test your unit. These things are not cheap. Welcome to the world of home repair. Please find my answer helpful, and good luck with your project. 25352024-u40lsvyytnuesyuv3fbafhtd-5-0.jpg

The unit just stopped extracting any moisture from the air. The fan runs and the compressor sounds like it turns on. I use the bucket to capture the moisture so do not have the pump on for the hose.


If the unit isnt extracting moisture in the air you have one of two problems a leak in the refrigeration system or the compressor is locked up. In my experience its probably a leak in the refrigeration system because they make the dehumidifiers very cheap and the coils are paper thin. Delonghi has a lot of issues with there dehumidifiers and any other appliance they make. Check to see if the compressor is running if it is then you have no freon in the system. You can access the compressor by the back panel and you will know if it is running. If it is a refrigeration leak buy a new unit it will be a whole lot cheaper and less stressful,.
If this helps please rate me.

I need a wiring diagram for a starndard residential split a/c system. Just the outdoor section is fine.


Hi, if this is just a split standard heating and cooling unit, and not a split heat pump, all you need to do is pull stat wire from the indoor unit control board to control the condenser with 5 conductors, but you will only use 2 wires for the control of the condenser. Normally, the red and white tie to the 2 control wires of the contactor. Back at the control board, red to red and white to the Y or yellow terminal. You will also need to set your disconnect box for your high voltage near the condenser, where you will be coming from your breaker to supply high voltage to run the motors and compressor. Very easy to do. If it is a heat-pump, you will need to pull at least 8 conductor thermostat wire to wire this up. I would also need to know what terminals and kind of thermostat you have, and if you are using heat strips for second stage of heat. When you say standard unit, you will only need 2 control wires from the indoor to the outdoor unit, along with the high voltage. Please keep me posted and let me know if you need more help on this. A wiring schematic wouldn't be needed if its just a standard condenser.

Where is the fuse located?


Hi, depending on what kind of set up you have, I will go with a central unit. They all have a main breaker. Central units that have a split system, have a disconnect box by the outdoor unit. Inside when you pull the plug out, most will have 2- cartridge type fuses inside. Some are on the block you pull out, and some are behind the plastic cover that you can't see. Also, depending on the age of the system, you will have a small 3 to 5 amp plug in fuse like you will find on your auto. It will be plugged into your circuit board to protect your low voltage power if you get a short in the controls at some point. This is all the fuses a system will have besides the breakers. Hope you find it OK. Please don't forget to rate me as I know you will be kind when you do. I will be checking back with you as I keep all people I try and help on file so I can do this, and please keep me posted on what you find.

Where is the fuse/breaker on a goodman cple 18-1


Hi, I wanted to look up the numbers you gave me as you listed 2 different model numbers, the CPLE-18-1 is a 1&1/2 remote condenser and the other you showed CPLE-24-1 is a 2 ton unit. Doesn't matter, but if your power was lost you have your main breaker box at your meter, and at the condenser you will have a disconnect box with a pull out type plug. If you see no fuses, try removing the plastic cover as they are required to install 2-fuses in side the box also. If this is a split system with the outdoor and indoor unit, you will also have a breaker inside for the indoor unit, its high voltage and you will have a circuit board in the indoor unit with a 3 to 5 amp auto type plug in fuse.
I hope this has helped you out on this. I will be here if you have more questions. Please do not forget to rate me as I know you will be kind. Keep me posted.
Sincerely,

Disconnecting the waterline


Hi, If you remove the grille below the doors, you can see a plastic water line passing through the lower hinge. Follow the line back about 6 inches and there should be a quick disconnect. It may be a screw type or the kind that you push down a small ring to get it to release

White 'dandruff like' flakes blowing from front & back of air con


this stuff is mold and mildew that builds up in the blower and evaporator section of your unit the unit needs to be cleaned out i'm not familar with this particular brand so I cant tell you how to pull it apart but since it is a split system this means the freon lines will most likely have to be pulled loose. you may try removing the covers and vacuming the unit as well as you can and possibly blowing it out with compressed air. aside from that I would recomend alling a qualified service comapny. good luck peyton
