Peterbilt 379 Installation Guidelines

INTRODUCTION

This document contains supplemental guidelines for installing the Qt-series control and air distribution for the
Dometic auxiliary air conditioning system on a Peterbilt 379 chassis with a 70" sleeper. It is intended to be used
in conjunction with the standard installation manual, which covers all other aspects of installing, testing and
operating this system.

These are suggestions based on previous installations. Please be creative in your installation, but keep functionality
and safety in mind. Key issues are: evaporator discharge venting, evaporator return air and condenser air flow.
Other issues include: controls accessibility, condensate removal and wire and hose chafe protection.

Do not attempt to install any components until you read and understand the instructions in both manuals.
