TCC Model Assembly Instructions

NOTICE

Roof Curb Structurally Sound

Check with curb manufacturer and job engineer to ensure the roof curb is structurally sufficient

to support the weight of the unit. The curb should be checked to ensure it is level and square.

Curb bowing, buckling, or sagging can lead to unit assembly and operation problems up to

complete failure.

If your nameplate model number begins with TCC, use the assembly instructions below.

TCC Overhang Base on Common Roof Curb

1. A base designed for use with a roof curb allows for 1/2- inch clearance around the full perimeter

of the curb.

2. The end section must be installed first making sure it’s properly aligned with the remainder of

the curb. Anchor this section securely so the base lugs can be used to pull the next section for

base connections.

3. Install 3/16-inch x 1.25-inch grey butyl tape to bottom rail of installed section allowing the tape

to turn up each side wall approximately 8 inches. Remove paper backing from butyl tape. This

will ensure the module-to-module joint is water tight along the bottom.

4. Lift next section onto roof curb using come-alongs to pull securely to first section. See “TCC

Joining Sections - Edge-to-Edge” on page 33 for assembly details.

TCC Flat Base to Steel Dunnage or Concrete Pad

Important: Units must be installed level for proper drainage of condensate from the drain pan

and for squareness of the sections during installation. In addition, each section in a

multi-section unit must be properly supported.

1. A base designed for concrete or steel dunnage has a flat channel base that allows the sections

to be installed level and square. Pad and dunnage should have unit perimeter marked clearly

allowing a completely square installation. See Figure 19 and Figure 20.

2. Install first section and anchor with best method to hold securely.

3. Proceed with remaining sections per installation guidelines.
