Your Guide to Replacing or Upgrading a Unico System

Purpose of This Guide

This guide is designed to help you upgrade older Unico Systems—or other small-duct systems—and to provide recommendations for a successful replacement project.

The guide is organized by:

1. Model Number — identifies your specific Unico System
2. Serial Number — provides additional details for your system’s configuration

Find your legacy model number below to access detailed replacement guidance for your unit, or use the lookup tool to quickly find the correct model match.

Identifying the System’s Age

You can determine the age of your Unico System by checking the serial number:

• The first two digits represent the year
• The next two digits represent the month

Example:
A serial number of 0012A123456 means the system was manufactured in December 2000.
