Question 3

Where is the filter of the CF 190 and what are the different operating modes?

Accepted Answer

Filter Location

The filter of the CF 190 is located in the rear grille of the unit. To access the filter:

Turn off the unit and unplug it
Gently remove the filter from the rear grille
Clean it with lukewarm water and mild soap, then let it dry completely
Reinstall it in the rear grille

We recommend cleaning the filter every two weeks during regular use, or more often in case of significant dust.

Operating Modes

The CF 190 offers three operating modes:

Cooling - cools the ambient air
Dehumidifying - dries the air without cooling
Fan Only - circulates air without cooling

For optimal efficiency, ensure that the unit is in Cooling mode and that the filter is clean.

Question 4

Why is my CF 190 blowing hot air instead of cooling?

Accepted Answer

If your CF 190 is blowing hot air instead of cooling, first check these points:

Essential Checks

Operating mode: Make sure the unit is not in "Fan Only" mode. This mode circulates air without cooling. Select "Cooling" or "Cold" mode.
Dirty filter: A clogged filter significantly reduces cooling efficiency. Clean the filter regularly, at least every 15 days with intensive use.
Drain hose: The CF 190 must expel hot air outside through a window or an opening. Check that the drain hose is properly connected, without knots or bends that would obstruct airflow.
Power supply: Confirm that the unit is receiving the correct voltage (220-240V depending on your region).
Room size: The CF 190 is designed to cool spaces up to approximately 25 m². If the room is much larger, the unit will not be able to maintain a satisfactory temperature.

If after checking these items the unit continues to blow hot air, there may be an internal issue (refrigerant or compressor) that requires the intervention of a specialized technician.

Question 5

The PAC FX140 ECO air conditioning does not start: only the ventilation works and the light 14 does not turn on

Accepted Answer

You are experiencing a common malfunction with the PAC FX140 ECO: only the ventilation (Light 15) works, while the air conditioning (Light 14) does not turn on. Here’s how to diagnose and resolve this issue.

Understanding normal operation

On your PAC FX140 ECO, the light 14 (Cooling/Dehumidification) turns on 3 minutes minimum after starting, once the compressor actually engages. This delay is normal and necessary.

Checks to perform in order

Wait exactly 3 minutes. You say you waited 5 minutes, but confirm that the light 14 still does not illuminate. If this is the case, move to the next step.
Check the function selector position. On the rotary knob, make sure you have turned the selector to the maximum crystal (❄) position. This position activates cooling at maximum speed. Position 0 or “spade” (♠) do not correspond to full air conditioning.
Check the drainage hose. The hose must be fully unrolled at the back of the unit. Ensure it is not bent, stuck, or blocked. A mispositioned hose prevents heat evacuation and may block the compressor.
Check the power supply. Plug another device (lamp, charger) into the same wall socket to confirm it is working correctly. The PAC FX140 ECO requires a grounded 230V ~50Hz socket.
Reset the device. Unplug it completely, wait 5 minutes, then plug it back in. Set the selector back to maximum crystal and wait at least 3 minutes.

Additional checks

Check the safety float. If the condensation tank is full, a safety device may block the compressor. Empty the water collection tray.
Clean the filters. Clean the antibacterial filter (vacuum) and replace the FILTRETE™ filter if it is heavily soiled. Clogged filters reduce performance and may affect the compressor's start-up.
Observe the resting time after transport. If you have just moved the unit, let it rest for 1 hour before first use.

If the light 14 still does not turn on after these checks

An internal failure is likely: faulty compressor, triggered thermal protection, or electronic issue. Contact DeLonghi customer service for repair or replacement under warranty. The unit may continue to ventilate (Light 15 only) without the air conditioning functioning.

Question 6

The device only works in ventilation mode, the indicator 14 does not light up despite the correct position of the selector

Accepted Answer

The indicator 14 lights up only in air conditioning or dehumidification mode, not in ventilation mode alone. If only ventilation is working, it means your selector is set to pure ventilation mode, and the indicator 15 should then light up (not 14).

Here’s how to activate the air conditioning:

Turn the function selector to the right (clockwise) to access the crystal symbol (❄). Use the large crystal for maximum speed or the small crystal for minimum speed.
After turning on the device, wait 3 minutes: the indicators will light up 3 minutes after starting (when the compressor starts working). This is a normal delay.
Indicator 14 will then light up to confirm that the air conditioning is active.

Important: If you turned the selector to the left (counterclockwise), you were in ventilation mode with active filtration. To switch to air conditioning, turn it clearly to the right until you reach the crystal symbol.

If after these steps indicator 14 remains off in air conditioning mode and the device does not cool, check that the ambient temperature exceeds 21°C (the minimum operating temperature of the device).

Question 7

How to start the DELONGHI NF170 air conditioner?

Accepted Answer

To start your DELONGHI NF170, follow these steps:

Make sure the device is plugged into an electrical outlet
Use the provided remote control to turn on the device
Press the Mode button to select the operating mode:
- Cool - to cool your space

The device will start operating as soon as you have selected a mode and the temperature.

Question 8

What is the cooling power in BTU of the DELONGHI PAC FX180 ECO air conditioner?

Accepted Answer

The official manual for the DELONGHI PAC FX180 ECO does not specify the power in BTU. However, you can find this information through several means:

On the rating plate of the air conditioner: usually located at the back or underneath the unit, it indicates the absorbed power and other technical parameters
Through DeLonghi customer service: by providing the serial number of the PAC FX180 ECO model
On the official DeLonghi website: check the complete product sheet for the PAC FX180 ECO for your region
From authorized dealers: they usually have the detailed technical sheet with all the BTU and watts

What we know about the model: it has a maximum air flow of 310 m³/h, 5 ventilation modes, and operates optimally between 21 and 32°C indoors and 21 to 43°C outdoors.

Question 9

What model of remote control does the PAC FX180 ECO use and where can I find a replacement?

Accepted Answer

The PAC FX180 ECO uses a remote control with LCD screen. According to the manual, it operates with 2 alkaline batteries and has a maximum range of about 7 meters.

However, the technical manual does not specify the exact code or model number of the remote control, making it difficult to find a replacement through general distributors.

Question 10

How to disassemble or remove the drainage hose from the air conditioner?

Accepted Answer

To remove the drainage hose from your DELONGHI Pinguino Smart PACEL140LRFK-3ALBK air conditioner:

Turn off and unplug the device from the electrical outlet before any intervention
Locate the fixing points of the drainage hose (B2) at the back and on the mounting brackets
