Frequently Asked Questions - ARP-904EC Royal Sovereign

How do I install the window kit for the ARP-904EC?

The window kit includes an adjustable panel and exhaust hose connector. Extend the panel to fit your window width, attach the hose to the connector, and seal the window with the foam strips provided. Ensure the unit is on a level surface.

Can I use an extension cord with this air conditioner?

It is strongly recommended to plug the unit directly into a grounded wall outlet. If an extension cord is absolutely necessary, use a 14-gauge or heavier, grounded cord with a length no longer than 10 feet.

How often should I clean the air filter?

Clean the washable foam filter every two weeks under normal use. More frequent cleaning may be needed if the unit is used in dusty conditions. Press the Filter Reset button on the control panel after cleaning.

Does the ARP-904EC have a dehumidifier mode?

Yes, it has a Dehumidify mode that removes excess moisture from the air without active cooling. In this mode, the fan runs continuously and the compressor cycles to condense water.

What is the recommended room size for this air conditioner?

The ARP-904EC is suitable for rooms up to 350 square feet. For best efficiency, ensure the room is well-sealed and not excessively large.

Why is my unit leaking water?

The ARP-904EC features self-evaporative technology, but under very humid conditions, the internal tank may fill up. The unit will stop cooling and display a full-tank indicator. Drain the water via the bottom drain plug and restart.

How do I set the timer on the remote?

Press the Timer button on the remote. Use the arrow keys to set the desired hour (1-24). Press Timer again to confirm. The unit will turn on or off after the set time, depending on current state.

The remote is not working. What should I do?

First, check the batteries and replace if needed. Ensure there is no obstruction between the remote and the unit's sensor. If still not working, use the control panel on the unit itself and contact customer support for a replacement remote.

What type of refrigerant does this AC use?

The ARP-904EC uses R-410A refrigerant, which is environmentally friendly and ozone-safe. Any service involving refrigerant should be performed by a certified technician.

Can I use this air conditioner in a room without a window?

The unit requires an exhaust outlet for hot air. If no window is available, you may use a sliding door kit or through-the-wall ventilation. However, proper venting is essential for cooling performance.
