TCC Energy Wheel and CDQ Wheel Assembly

Units are shipped unstacked.

1. Set sections 1 – 5 of the unit in place in sequence order as shown in Figure 36 and secure as

needed.

– Prior to setting section 2 and 3 apply 2-in. x 1-in. thick gasket across full unit width along the

wheel’s upper-to-lower septum.

2. Prior to upper unit placement, install 0.188-in. x 2-in. gasketing on entire length of engagement

plate and/or lower unit perimeter as needed. Engagement plates are used when the upper and

lower unit dimensions are not matched. Refer to “TCC Stacking Procedure” on page 40.

3. Apply two layers of 1-in. tall x 2-in.wide gasketing around perimeter of roof opening in lower

unit section prior to lifting upper unit. Refer to “TCC Stacking Procedure” on page 40.

Note: If gasketing is not installed first, leakage may occur between the upper and lower units and

will result in CFM loss.

4. Upper unit with duct opening should be placed within 1-inch of lower duct opening in order to

sufficiently compress gasket.

– Once unit is set in place verify the gasket seal between openings.

5. After installing all of the upper unit sections, Install all-thread rods (field-provided) fastening

both upper and lower sections to the wheel section.

6. Fasten the upper unit to the lower unit perimeter cap with ¼-inch self-drilling screws through

base rail.

Note: A drill extension will be required to ensure straight alignment.
