# 8 Maintenance

## 8.1 Maintenance of the Micro Modular System[](http://127.0.0.1:8000/#operation-manual/maintenance/#maintenance-esite-modular) <a href="#maintenance-esite-modular" id="maintenance-esite-modular"></a>

{% hint style="info" %} <mark style="color:blue;">Note</mark>

<mark style="color:blue;">Micro Modular is a low maintenance system. The Converter Unit contains no fans or filters that require maintenance.</mark>
{% endhint %}

The passive convection cooling implemented for all Converter Units works optimally when the ambient air flows unobstructed through the airways (see figure 8.1). Remove any debris, dry leaves, spider web or dirt that may obstruct normal airflow.
