<ul class="cause-list">
            
<li>Noise is generated before stabilization in the early phase of operation.</li>
            
<li>It is oil recovery operation.</li>
            
<li>It is defrosting operation during heating operation.</li>

<h2 class="tit">Try this</h2>
        
<h3 class="sub-tit">Is the noise temporarily heard when starting or stopping the outdoor unit?</h3>
        <p class="info-desc idt">➔ When the outdoor unit turns on or off, depending on the installation location, noises can be heard.</p>        <p>The closer the indoor unit is to the outdoor unit the relatively louder the noise might get, so it does not mean the production malfunctions or has an issue.</p>        
<h3 class="sub-tit">Is the noise intermittent for about 5 minutes?</h3>
        <p class="info-desc idt">➔ It is oil recovery operation and it might generate unusual noises once every five minute for the time period of about 8 hours.</p>        <p>The oil recovery operation plays a role in restoring the oil level of the compressor oil by recovering the oil accumulated in the pipe back to the outdoor unit.</p>        
<h3 class="sub-tit">While using heating operation, is the noises occurring intermittently?</h3>
        <p class="info-desc idt">➔ As the outdoor unit enters the defrosting mode, the direction of refrigerant(gas) will be changed, thus generating noises.</p>        <p>This cycle intends to maintain the product performance for a long time, and it does not mean a malfunction and you can rest assured when you use it.</p>        <p class="help-txt">This guide was created for all models, so the images or content may be different from your product.</p>    </div>
