8. Attach Duct to Unit

• Raise the brace assembly and slip the black

plastic duct over the outside of the fan

outlet underneath the rooftop unit. Ensure

that the notch cut in the plastic ductwork

aligns with the fans power cable (Fig 12).

When attaching the duct to the unit take

care to ensure it forms a tight, unbroken seal

that doesn't allow cold air to escape.

• Engage and tighten the four M8 bolts with

the threaded inserts in the rooftop unit.

• Recommended tightening torque of the

bolts is 7 N.m (5.2 lbf-ft).

• As the bolts are tightened ensure that the

hold down bars slot into their recesses in

the brace (Fig 11).

Then engage the four M8 bolts, taking care to ensure the hold down bars

slot into their recesses.
