Be sure the electrical service is adequate for the model you have chosen. This information can be found on the serial plate, which is located on the side of the cabinet and behind the grille.

• Be sure the air conditioner is properly grounded. To minimize shock and fire hazards, proper grounding is important. The power cord is equipped with a three-prong grounding plug for protection against shock hazards.

• Your air conditioner must be used in a properly grounded wall receptacle. If the wall receptacle you intend to use is not adequately grounded or protected by a time delay fuse or circuit breaker, have a qualified electrician install the proper receptacle.

• Ensure the receptacle is accessible after the unit installation.

How to Fix P1 Error?

When the water level of the bottom tray reaches a predetermined level, the unit beeps 8 times, the digital display area shows P1. At this time the air conditioning/dehumidification process will immediately stop. However, the fan motor will continue to operate (this is normal). Carefully move the unit to a drain location, remove the bottom drain plug and let the water drain away (Fig.24). Restart the machine until the P1 symbol disappears. If the error repeats, call for service.

During dehumidifying modes, remove the drain plug from the back of the unit, install the drain connector (5/8” universal female connecter) with 3/4” hose (locally purchased). For the models without a drain connector, just attach the drain hose to the hole. Place the open end of the hose directly over the drain area in your basement floor. Please refer to Fig.22 & 23.

NOTE: When operating or draining water always protect carpeting or floors from possible water spillage.

Air Filter

Clean the air filter at least once every two weeks to prevent inferior fan operation because of dust.

Removal: This unit has three filters. Take the upper filter out along the arrow direction (Fig.25), then take the filter down. Remove the lower filter and the side filter by loosening the screws, taking out the filters as shown in Fig.25.

Cleaning: Wash the air filter by immersing it gently in warm water (about 40°C / 104 °F) with a neutral detergent. Rinse the filter and dry it in a shady place.

Mounting: Install the upper air filter after cleaning ,then insert the side filter into the unit and install the lower filter by using the screws (see Fig.26).

  1. Hi there, I have a Danny portable that’s a week ole and randomly it shuts down and displays an error code PC 02

  2. Hi, I took apart my portable AC to clean it out, now when I plug it back in I’m getting a E4 code and a red light at the power button. I can confirm that all parts on my AC unit are well above 8°c. It was sitting in the hot sun for about 6 hrs before I brought it inside.

  3. Since the day I purchased my heat/cool floor model the wifi has not worked. Hold the swing button for 3 seconds it will beep but AP has never come up on the display. Tried with the remote and the QR Code and still it does not connect. It is out of warranty now because if covid so I can’t even have it repaired. Any help would be appreciated. Unit works great otherwise. Very happy with its functionality.

  4. Any idea why a Danby portable unit model 140HEAUBDB beeps 3 times right after it is plugged in and it won’t come on either from the control panel button or the remote button? The display powers on and shuts down after the 3 beeps. No error number on the display.

    • Hi Sergio
      Did you ever find an answer to this issue? Mine is doing the same thing. Just tried to start it up after taking it out of storage (for the winter). Worked fine when it was put away.

  5. I got an E4 error right out of the box on my 14000 BTU portable danby Ac. Anyone have any suggections? Waiting for customer service but it’s a heat wave and we have a new baby that can’t get over 25 degrees. Help!!! please….

  6. My Danby unit does not stop cooling when the tray is full of water. Instead, it continues to cool and allows water to leak out of the unit. No error codes, no P1 indicator, nothing…. Just waking up to water on the floor and going through to our basement! The unit is level and it has done it on two separate uses now so resetting the unit is not a solution. I contacted customer support and am waiting for a reply but we are in a heat wave and if I can get an answer sooner, awesome! Ideas?
    Note: Continuous drainage is not an option for us at the moment.

  7. What is Fe mean? How to fix it? I have Danby 14,000 BTU 3-in-1 Portable Air Conditioner with Silencer and Wireless Connect

  8. Have my unit about 2 years now and the mode button on the unit stopped working so it is stuck on heat and the remote completely stopped working as well. Tried new batteries and everything. The rest of the buttons on the unit work fine except the mode button.
