General

This document provides installation, operation, and maintenance information for the Titus Horizontal Air Handler Belt Drive (HAB) models.
Additional information may be found at the Titus website, its address is www.titus-hvac.com.

Introduction

The following information is to be used by the installer as a guide. Since each installation is unique unto itself, only general
topics are covered. Installation may not occur in
the same order as topics are presented.
This guide does NOT supersede or circumvent any applicable national, state, or local codes.
The installation is to be performed only by individuals whose experience meets or exceeds the requirements of the work involved.
The installer MUST read the entire contents of this guide and develop a thorough understanding before beginning installation.
Due to a continuing program of product research, Titus reserves the right to discontinue or change without notice, any or all specifications or designs without incurring obligations.

Safety

The installation and/or servicing of comfort conditioning equipment can be hazardous due to system pressures and electrical devices.
Caution: Only trained and qualified personnel should perform service and/or installation.
Observe all precautions and warnings in product data or attached to the unit.
Follow all safety codes. Wear eye protection and gloves. Have a fire extinguisher readily available.
Caution: Disconnect all power supplies before accessing equipment.
Disconnecting more than one power supply may be required to de-energize some equipment.
DANGER
ELECTRIC SHOCK CAN CAUSE DEATH.

Inspection

Thoroughly inspect all packages upon receipt. Ensure carton(s) have not been dropped, crushed or punctured. Inspect all contents for damage. If damage is found, immediately file a claim with the delivering carrier.

Standard Installation

Basic installation procedure covers verifying and/or installing the following items.
Ductwork.
Duct insulation and vapor proofing.
Unit placement.
Sound attenuation.
Condensate drain.
Water piping.
Motors and drives.
Electrical connections.
Note: If mixing boxes form part of the unit, install the mixing boxes prior to installing unit. See Mixing Box Installation topic within this document.

Ductwork

Use accepted industry practices and design guidelines of the ASHRAE Fundamentals H comply with all building codes and the National Fire Protection Association’s pamphlet 90A and 90B.
Carefully inspect any previously installed ductwork to determine suitability.
Note: Ductwork should be of a size meeting requirements of the installation. Ductwork should transition gradually from a smaller size blower outlet to required duct run size to avoid excessive loss of air velocity.

DANGER
BEFORE INSTALLING UNIT, DETERMINE WHETHER
THE UNIT WEIGHT CAN BE SUPPORTED SAFELY.
POSSIBLE INJURY AND DAMAGE MAY RESULT DUE
TO JOIST/TRUSS OVERLOADING.
When return air duct connection is smaller than return inlet opening, construct the transition piece so the vertical and horizontal dimensions of transition do not increase more than one inch for every seven inches of length.
Allow a minimum of three feet of straight ductwork following an equipment outlet.
Suspend unit or support unit from floor. Models HAB08 through 20 have 3/8-inch weld nuts provided in each corner of the top for suspending the unit with threaded rod. See Figure 3. Models HAB30 through 80 have 7/8­inch knockouts in each corner of top and bottom panels for suspension rods to pass through, located 3-1/2 inches in from corners on centerline. It is recommended that angle iron or unistrut be used under the unit for support (these support pieces should extend approximately one inch beyond each end of the unit, see Figure 4.
Ensure the suspension rods are located so the rods do not block ac mechanical or drain functions of the unit.
Install unit with 1/8-inch pitch toward condensate drain opening.

HAB Installation Manual
Externally insulated ductwork must have adequate vapor seal for summer operation, especially where duct is exposed to high humidity conditions.

Condensate Drain

Condensate drain must consist of a minimum of ¾-inch copper tubing, ¾-inch galvanized pipe, or ¾-inch PVC pipe. Figure 5 shows condensate drain setup. The drain trap must be properly configured to ensure the removal of all condensate runoff. Ensure drain pitches downward at a slope of one inch every 10 feet.
Note 1: Incorrect trapping can hold water in pan, causing overflow.
Note 2: Consult local codes for additional precautions before instal
Caution: If unit location is above an occupied space or where damage may result from condensate overflow, install a watertight pan of corrosion-resistant metal beneath unit to catch overflow. If this condition exists, a separate ¾-inch condensate drain must be provided for this added pan. See Figure 6.

Duct Insulation and Vapor Proofing

Previously installed heating supply ductwork may already have adequate insulation against excessive heat loss. This insulation may be satisfactory for protection against heat gain from summer cooling. Depending upon application, additional insulation may be required.
