Section 1

Can I add or install additional exhaust hoses to my unit?

No, the units are designed with the hoses included. If you add additional hoses the compressor will shut down from backpressure, and cause the output air to be warm. This will diminish the efficiency of the unit. Changing the length of the exhaust hose may also void your warranty and even cause your unit to overheat.

Can I install my portable air conditioner in an tight, enclosed area such as a cabinet?
No, there must be ample space to allow airflow around the unit and air intake. The unit may overheat.
Can I install the unit without an exhaust hose?

No, the unit will just recycle hot air back into the room and in the case of the unit with heat function cold air would be recycled back into the room. 

Can I remove the styrofoam packing material inside my unit?

No, do not remove. This is not packing material but the internal fan housing; since the units are compact and made to be portable, this part was designed with a high grade Styrofoam to make the unit as light as possible for easy mobility. 

Can I setup the unit for continuous drainage?

Yes, some of our models do come with a drain tube which can be installed over the drain after removing the cap and plug. The drain tube would then need to be on a downward pitch and draining to the outside or into an ample drainage system. Keep in mind that the units may run a bit hot, but that will not affect the unit. Also continuous draining bypasses (disables) the internal water full safety mechanism.

Can I wash and re-use the black filter?
Yes.
Does my portable air conditioner need to be vented?

Yes, hot air is exhausted out the back of the unit and must be vented to the outside via window, through a wall, or existing duct work.

A window kit is included that is designed for double hung and sliding type widows up to 43”.

Section 2

How do I change the temperature display readout from Celsius to Farhenheit?

Press and hold the down/up or (-)/ (+) buttons at the same time until the number switches.
How do I install my portable air conditioner?

Installation guides can be found in your owner's manual.  If you lost or misplaced your owner's manual, please visit our owner's manual download page at support > owner's manuals.

How do I purchase replacement parts?
You can order replacement parts at support > parts and accessories

How do I know when or how often I need to empty the water reservoir or drain my unit?

There is a safety shut off on the unit. When the reservoir is full, the unit will stop running and the water full indicator will light up.
How do I properly store away my portable air conditioner for the winter?

If the appliance will not be used for a long time, completely drain the water.
Run the unit in fan mode only for a half day to dry the appliance inside to prevent mold.
Unplug the unit and store cord.
Take out the batteries of remote controller.
Clean the air filter and reinstall it.
Remove the air hoses.
Replace in the original carton or cover for storage.
Always maintain the unit in an upright position and store in dry place.

How do I use my external water tray?

The external water tray is to be used for draining the unit when the internal water tray is full. Position the external water tray under the drain at the bottom rear of the unit then remove the cap and plug and let water fill the tray. Do this until no more water comes out of drain and when completely drained reinstall the plug and drain cap. The external water tray is not recommended as a water catch for continuous drainage for the size is not ample enough. Remember the water full safety mechanism is bypassed (disabled) when setup for continuous drainage.                                                                                                                                                                                                                          If you are continually draining into anything you must keep in mind you will have to keep an eye on this to prevent water overflow.

How far can I bend or extend the exhaust hose?

We do not recommend bending the exhaust hose more then a 45 degree angle or extending the exhaust hose longer than its intended use.  Bends beyond 45 degrees may  restrict the air flow which will cause back pressure and cause the output air to be warm. The unit works most efficient when the exhaust hose is as straight and as short as possible. 

How long can I extend the exhaust hose?

Do not extend the exhaust hose further than its intended use.  Doing so may cause the unit to over heat or perform at an innefficient rate.

Is it normal for my portable air conditioner unit to be louder than conventional window air conditioner units?

Yes, this is the sound of the compressor turning on. This is similar to the way a refrigerator works. 

How do I identify the model number of my unit?

You can check the back of the unit for the model number listed on the label. The numbers 900, 1000, 1200 refer to the BTU (times 10). The “E” refers to the unit being electronic with remote control. The “M” refers to the unit having manual dial controls. The “D” refers to the unit having dual capabilities of cool and heat functions. The “X” refers to two exhaust hose system. For example: Model ARP-900DE would be 9000 BTU with heat and cool function and electronic control panel with remote control. 

Section 3

What types of windows are suitable for my Portable Air Conditioner?

Royal Sovereign Portable Air conditioners include a window kit (two pieces which can be adjusted from 20 inches to 48 inches) to fit most sliding and double hung windows. (Please note that Royal Sovereign window kits are not universal and can vary in size, example: ARP-2412 both pieces are 26 inches long)

What if my window kit does not fit in my window or exhaust opening?

We do not offer other size window spacer at this time. You can cut the spacer to size if it is to long or you can fill the space with foam or we suggest using Plexiglass which you can purchase and have cut to size from your local hardware store or home center. For any small gaps we suggest purchasing weather stripping from your local hardware store or home center.  You can also purchase window kits on our supports page under parts and accessories. 

What is AUTO MODE?

When in auto mode the unit is factory preset to about 75 degrees and the set temp up or temp down buttons are disabled even though it appears you can set the temperature up or down when pressing the buttons. Make sure the unit is in cool mode by pressing the mode button and only the cool light is on and the auto light is off then you can set your desired temperature. After a few minutes the compressor will come back on.

Why is my air conditioner not turning on?

Test the outlet that the PAC is plugged into is working. If the outlet is working than the powerplug breaker needs to be replaced. If the wall outlet is not working, there may be too many appliances on one circuit. Recommended circuit is 20amps.  You can also administer a power plug check:                                                                                                                                                                          Power Plug Check
1. Press the RESET button.  The reset button may be stubborn so you will need to press HARD to reset it until a click is heard and the light comes on.
2. Insert the power plug into the electrical outlet.
3. Press the TEST button. If the circuit breaker is working you’ll hear a click.
4. Press the RESET button until you hear another click. The circuit breaker in the plug is now activated.
5. Do not use the air conditioner if the above procedure cannot be successfully performed.
After switching the air conditioner off, wait 3 minutes before switching it back

Why is my compressor not turning on?
Please set the desired temperature and wait 1-3 minutes for the compressor to turn on.
Why is my portable air conditioner is leaking water on the floor?

Make sure the unit is on a flat, level surface. If the floor is not level or the carpeting is too thick, the unit will not be level, causing the water in the internal tray to flow to one side.  This will bypass the water full safety mechanism and the unit will not automatically shut off.

Check for broken or damaged casters. Check to make sure the casters are installed securely and evenly.

Check and make sure the drain cap and/or the rubber plug is installed. If cap or rubber plug is missing, use a cork. Check and see if the drain is cracked or broken, if so, shave broken drain flat and use a cork. You can use a plumbing adhesive or epoxy to repair the drain. For additional assistance, contact Royal Sovereign customer service. 

Why is the temperature on my air conditioner stuck on 75 degrees? 

Check to see if your AC is set in Auto mode. If your AC is in auto mode it is set at approximately 73-77 degrees.  To change the temperature, turn the AC to cool mode and select desired temperature. 

Why is my room not getting cool even though the air conditioner is blowing cold air?

Make sure the room size is not to large for the BTU’s of the unit, check your manual; you may need a higher BTU unit. The units are designed for zone cooling so make sure all doors to adjoining rooms and hallways are closed. Make sure all windows are closed and there is not excessive sunlight coming in; keep drapes and curtains closed if necessary. Check the back of the unit for any exhaust leaks and secure if necessary. Make sure the exhaust hose is installed properly, securely screwed into the adapter and there are no kinks in the hose. Make sure there is no outside air coming through the window spacer. Apply weather stripping to any gaps or fill in any large gaps with foam or Plexiglass from your local hardware store or home center.

Why is the COMP/ALARM light flashing or on?
Units internal water pan is full and needs to be drained.  The unit will not turn on unless the COMP/ALARM light error is fixed.
Why does my portable air conditioner cool for a short period of time and then turn off?

Have you extended the exhaust hose with another? The unit can ONLY be used with the included exhaust hose (dryer type exhaust hoses will cause the unit to over heat).

How close is the unit to the wall? If the unit is only inches away from the wall and you are running the exhaust hose out a window, more than likely their exhaust hose bend is at 90 degrees which restricts air flow. In order for the unit to run more efficiently and not overheat, it should be at least 1-1/2 feet away from the wall and the exhaust hose should not exceed more then a 45 degree angle.  
                                                                                                                                                                                                                                     Are you exhausting the unit out a hole in the wall? If so, are you using a flap vent on the exterior of your home/office? The flap may be too rigid and not open continuously. The compressor is not strong enough to push the air through and therefore will only run for a short period of time before overheating and shutting off. You should take the flap off the vent and replace it with a piece of screening.

Are you venting it into a ceiling or basement? Does the ceiling or basement have ample ventilation? If the ceiling or basement does not have a way of pushing the heat from the exhaust to the outside, the unit will work for a short period of time and then eventually overheat and shut off.

Why is my unit not blowing cold air?
Make sure there is no obstruction in the exhaust hose and the hose is not kinked or overly bent. Make sure you don’t exceed the recommended hose length of 4 or 5 feet depending on which model you have. Make sure there is ample space around the unit and there is nothing obstructing the air flow of the intake, check your manual for space requirements. Make sure your unit is in cool mode.
                                                                                                                                                                                                                                Check your set temperature. Make sure it is set at a cooler temperature than your room temperature.  If your AC is in auto mode it is set approx 73-77 degrees. For colder air please change from auto mode to cool mode and set desired temperature.
                                                                                                                                                                                                                                Check to make sure the unit is not in auto mode. When in auto mode the unit is factory preset to about 75 degrees and the set temp up or temp down buttons are disabled even though it appears you are setting the temperature up or down. Make sure the unit is in cool mode by pressing the mode button and only the cool light is on and the auto light is off then you can set your desired temperature. After a few minutes the compressor will come back on. Make sure air intake is clean and filter is clean.
