Titus T Series Fan Coil and Blower Coil Units

INSTALLATION GUIDE

INTRODUCTION

Titus fan-coil units and blower-coil units which are applied in facilities subject to seismic activity have special construction features and need to be installed as detailed in this document. They can be identified by their seismic labels, which are similar to the example label in Figure 1. The label lists:

• The unit model
• The applicable test standard(s)
• The applicable building code(s)
• The seismic-resistance test value

The certified Sds rating shown on the label is only IBC-certified when installed in accordance with this document. Installations which deviate from these procedures must be approved by an engineer licensed for seismic certification.

Cables, threaded rods, and other miscellaneous items are to be supplied by others. Items mounted in the field (such as piping packages, electrical panels, ductwork, etc.) to IBC seismically certified HVAC equipment are not considered part of the equipment certification. Field-mounted items are required to be supported and restrained in accordance with recommended seismic installation practices and may include, but not necessarily be limited to, the use of flexible piping connectors. The installation of these field-mounted items, and any restraints / supports, is the responsibility of the installing contractor.

This seismic installation document is intended to supplement the standard Installation, Operation, Maintenance manual, and shall take precedence over the standard manual in areas where overlap occurs. This document is organized by Model.

MODEL TBHD CEILING-MOUNTED UNITS

NOTE: For all models, unit size can change the installation method.

SIZES 08-20

Unit is hung from the ceiling using strut screwed to both the top and bottom of the unit on both the front and the back. See Figure 2.

A 1/2-inch threaded rod is run through the base rail on the bottom of the unit and the solid rail on the top of the unit. Each rod is stiffened with unistrut, and B-line, 1/2-inch clips, spaced no more than 22 inches on center. Lateral bracing is provided by 14-gauge, 45-degree brackets, washers, and 3/16-inch cable with four saddle clamps (wire rope grips) per cable (two grips at each connection). Grips are installed as per FEMA 414. See Figure 3.

Also, see Table 1 for list of brackets supplied by Titus. Brackets as listed are minimum gauge thickness. Actual thickness may vary.

Four 3” x 3” 12-gauge plate washers
Eight 4” x 4” 12-gauge plate washers

SIZES 30 & 40

Threaded rod, 5/8-inch diameter, grade 2, is run through the manufacturer- supplied, 12-gauge, 1-5/8-inch strut on the bottom of the unit, and the solid strut screwed to the top of the unit. See Figure 4.

The unit shall be laterally braced using 45-degree, 12-gauge, galvanized- steel, outside angle brackets and 3/8-inch diameter, general-purpose cable (6 x 19 Class IWRC) with four saddle clamps (wire rope grips) per cable (two grips at each connection). Grips are installed as per FEMA 414.

Each bracket shall attach to the frame using a 1/2-inch, grade 5 bolt. The brackets attached to the solid strut at the top of the unit shall be sandwiched between one 3-inch square, 12-gauge plate washer on the bottom and two 4-inch square, 12-gauge plate washers on top.

Unit is ceiling-mounted using one 12-gauge, 90-degree bracket, one 12-gauge, flat bracket, and one 12-gauge, 45-degree bracket at each of the mounting points. The flat bracket and the 90-degree bracket attach to the unit using four #12, 3/4-inch sheet metal screws. The flat bracket overlaps the 90-degree bracket. The 45-degree bracket is located on top of the flat bracket. A 1/2-inch, threaded rod is run through the flat bracket, 90-degree angle bracket, and 45-degree angle bracket, and a nut and washer are placed on the top and the bottom of the brackets. See Figure 5.

Each threaded rod is stiffened using a length of unistrut and three B-line, 1/2-inch clips. Clips are placed two inches from the top and bottom of the unistrut, and one is placed at the approximate middle. Lateral bracing is accomplished using 12-gauge, 45-degree brackets. Brackets are attached to 3/16-inch cable with four saddle clamps (wire rope grips) per cable (two grips at each connection). Grips are installed as per FEMA 414. It is recommended that the cables be adjusted prior to final tightening of the top locking nut on the threaded rod. See Figure 6. Also, see Table 2 for Titus supplied brackets.

One 2” x 6” x 12-gauge plate – 45-degree
One 3” x 6” x 12-gauge plate – flat

Hanger brackets listed above are minimum gauge thickness requirements. Actual thickness may vary. An instructional document will ship with the units, detailing the locations where the brackets should be installed.

Unit is ceiling-mounted using two 12-gauge, 45-degree brackets, and one 12-gauge, flat bracket at each of the mounting points. Each 45-degree bracket is located below the flat bracket. A 1/2-inch, threaded rod is run through each flat bracket and 45 degree angle bracket, and a nut and washer placed on the top and the bottom of the brackets. See Figure 7.

Each threaded rod is stiffened using a length of unistrut and three B-line, 1/2-inch clips. Clips are placed two inches from the top and bottom of the unistrut, and one is placed at the approximate middle. Lateral bracing is accomplished using 12-gauge, 45-degree brackets. Brackets are attached to 3/16-inch cable with four saddle clamps (wire rope grips) per cable (two grips at each connection). Grips are installed as per FEMA 414. It is recommended that the cables be adjusted prior to final tightening of the top locking nut on the threaded rod. See Figure 8. Also, see Table 3 for Titus supplied brackets.
