Conduct Drainage Tests for Floor/Low-Wall Mounted Systems

This article explains how to run and complete a drainage test for single-way ceiling cassette systems.

<h2 id="isPasted">Introduction</h2>This article explains how to run and complete a drainage test for <a href="https://www.pioneerminisplit.com/collections/cyk" target="_blank" rel="noopener noreferrer">single-way ceiling cassette systems</a>.&#xA0;The drainage plug at the bottom of the unit is used to empty the drain pan if the air conditioner malfunctions. During normal operation, ensure the plug is securely in place to prevent leaks.Before the test, ensure the water discharge pipeline is smooth. In addition, check that each connection is sealed properly. New buildings should perform this test before finishing the ceiling.&#xA0;<h2 id="steps">Steps</h2>1. Connect the power supply and set the air conditioner to Cooling mode. Listen for the sound of water flowing through the drainage pipe.&#xA0;2. Allow Cooling mode to run for at least 10 minutes.&#xA0;3. Stop the system. Wait for 3 minutes and then check for any abnormalities.&#xA0;If the water discharge piping layout is incorrect, excessive water flow will cause a water level error, and the &quot;EE&quot; error code will appear on the display panel. There may even be water overflowing from the drain pan.&#xA0;4. Continue adding water until the high-water alarm triggers. Check that the drainage pump begins operating immediately.&#xA0;If the water level does not fall below the warning line after 3 minutes, the unit will shut down. If this occurs, disconnect the power supply and manually drain the accumulated water before restarting the unit.&#xA0;5. Turn off the power supply, remove the water manually using the drainage pipe, and put the test cap back to the original position.&#xA0;
