Installation - Mechanical

TCP Joining Sections Edge-to-Edge

Units must be installed level for proper drainage of condensate from the drain pan. In addition,

each section in a multi-section unit must be properly supported.

Note: Leveling each section, beginning with the first, is critical. Failure to level and align the

sections immediately creates greater misalignment or even structural damage afterward.

1. Remove all crating and wrapping from the surfaces to be joined.

2. Place one section of the air handler into the desired position. Verify section is installed level

front to back and side to side. Verify section is square to support structure, this is critical to

insure proper alignment for next adjoining sections.

3. Check squareness measuring the critical dimensions given. Use preselected method to anchor

first piece in place. This is necessary so movement will not affect pulling next sections into

alignment.

4. When the unit is positioned and squareness is ensured within 1/8-inch, remove all lifting lugs

located along the split plane.

5. After assuring positioning is correct, anchor in place either by welding unit base to the curb or

by mechanical fasteners. The first section will be used to pull remaining sections up tight so it’s

critical that first section be secured.

6. Install 4-inch x 1/4-inch neoprene gasket to all mating surfaces of the section, including any

internal walls. This gasket must be applied to the full perimeter of the section split on both

sections to be joined.

7. Move the next mating section into alignment with the positioned section. Alignment of sections

must be completed before gasket surfaces meet. The two sections should be within 12 inches

to reduce the amount of dragging required.

8. Remove lifting lugs on mating section as required.

Figure 9. Insert supplied bolts through each hole of

mating connecting plate.

9. Pulling sections together on a flat surface can be done by

using chain come-alongs hooked onto the welded square

tubes located on each side of the shipping split. These square

tubes are designed to fully support the stress of pulling

sections together. Sections should be pulled together until

mating gaskets make contact and factory-supplied bolts can

be installed in connecting plate.

10. When sections are close enough to allow full threading of the

factory-supplied nut onto the bolt, chain come-alongs can be

removed. The use of an electric impact gun to tighten bolts in

a sequential manner will allow the additional section to be

pulled into the final position.

11. Check overall unit length to assure proper joint compression.

Note: Failure to compress the gasketing may result in air

leakage.

12. Once the sections are pulled together, install the assembly

hardware as applicable for the walls, roof, and the base as

demonstrated in the following assembly sections.
