Frequently Asked Questions - KSTAP13MFHC Keystone

How do I install the Keystone KSTAP13MFHC portable air conditioner?

Install the included window kit in a sliding or double-hung window. Extend the exhaust hose from the unit to the window kit adapter. Ensure the unit is on a level surface. For detailed steps, refer to the installation section of the manual.

How often should I clean the air filter?

Clean the washable mesh filter every two weeks under normal usage. Remove the filter, wash with lukewarm water, dry completely, and reinsert. A clogged filter reduces efficiency.

Can I use the air conditioner without the exhaust hose?

No, the exhaust hose must be connected to vent hot air outside. Without it, the unit cannot cool properly and may overheat.

What does the 'Auto Restart' feature do?

If power is interrupted, the unit will automatically resume operation with the previous settings when power returns. This prevents loss of cooling during brief outages.

How do I drain the collected condensate?

In humid conditions, the unit collects water. It can be drained manually via the drain plug at the back, or continuous drainage can be set up with a garden hose (sold separately).

What is the recommended cooling area for this model?

The KSTAP13MFHC is suitable for rooms up to 550 square feet. For larger spaces, performance may be reduced.

Why is the unit blowing warm air?

First, ensure the exhaust hose is properly connected and not kinked. Check the air filter for dirt. Also, verify that the selected mode is 'Cool' and the temperature setting is below room temperature.

Can I use an extension cord with this air conditioner?

It is recommended to plug the unit directly into a grounded 115V outlet. Do not use an extension cord, as it may cause voltage drop and overheating.

How do I set the timer to turn off the unit?

Press the Timer button on the remote or control panel. Use +/- to set the number of hours until shut-off. The unit will turn off automatically after the set time.

What should I do if the unit displays an error code?

Refer to the troubleshooting section of the manual. Common codes: E1 (sensor error), E2 (coil sensor), E3 (overheating). Unplug for 10 minutes to reset; if persists, contact customer support.

Notice for R410A Models

Refrigerant leakage contributes to climate change. Refrigerant with lower global warming potential (GWP) would contribute less to global warming than a refrigerant with higher GWP, if leaked to the atmosphere. This appliance contains a refrigerant fluid with a GWP equal to [2088]. This means that if a 1 kg of this refrigerant fluid would be leaks to the atmosphere, the impact on global warming would be [2088] times higher than 1 kg of CO_2 , over a period of 100 years. Never try to interfere with the refrigerant circuit or disassemble the product by yourself, always ask a professional.

WARNING

1. When you need to dispose of the unit, consult with your local dealer or local recycling center for information on how to dispose of the unit in an environmentally responsible manner.

2. Please recycle or dispose of the packing material for product in an environmentally responsible manner.

*If the unit you have bought has the pump drain outlet, as shown below, please drain in this way:

Remove the pump drain from the back of the unit, attach the drain hose to the hole. Place the other end of the hose in the drainage way, or other drainage area such as a window.

Note: Make sure the hose is secure and there are no leaks. Direct the hose towards the drain, making sure that there are no kinks that will stop the water flow. Place the end of the hose into the drain, and make sure that the end of the hose is down to let the water flow smoothly.

* When the water level of the bottom tray reaches predetermined level, the digital display area shows “P1” and the WATER FULL indicator light illuminates. Carefully move the unit to a drain location, remove the bottom drain plug, and restart the machine until the P1 symbol disappears. If the error repeats, call for service.

Note: Be sure to reinstall the bottom drain plug before using the unit.

Install the exhaust duct into the wall

1. Prepare a hole in the wall. Install the wall exhaust adapter onto the wall by using 4 expansion screw sleeves and type C screws, be sure to fix thoroughly.
2. Connect the exhaust duct to the wall exhaust adapter. (Fig. G)

Note: 1. The duct can be compressed to 27 ~cm minimum and extended to 150 ~cm maximum. It is better to keep the duct length to a minimum length. 2. Stretching or bending the duct excessively will affect the cooling efficiency. (As the following fig. shows)
