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.

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.
