9. ATTACH DUCT TO UN I T
- Raise the brace assembly and slip the
extension duct over the outside
diameter of the spigot underneath the
rooftop unit. (Fig 11 & 12).
When attaching the duct to
the unit take care to ensure i t
forms a tight, unbroken sea l
that doesn’t allow discharge air to
es c ape .
- 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 lb-ft). As a rough
guide the bolts should be tightened so
that the unit compresses the roof seal
gasket to approximately half its height.
- As the bolts are tightened ensure that
the hold down bars slot into their
recesses in the brace (Fig 12).
Fig 11: Raise the duct assembly up to the roof hole, ensuring the paper extension duct work
forms a tight fit around the spigot underneath the unit.
