I. Introduction

Kooltronic Hazardous Location Air Conditioners (HL Series) are designed to provide a cool, dehumidified
environment for your electronic components. Our "closed-loop" design also ensures that your components
will not be exposed to hot, dirty operating conditions.

This Manual provides you with the necessary general information for properly installing and operating
standard Kooltronic Air Conditioners. Mounting instructions and technical data are presented on pages
12 through 15.
