Fan Installation
Take care when handling the fan as poor handling can adversely affect its balance.
Install the fan in the reverse order of its removal.

IMPORTANT
After installation, rotate the impeller by hand to verify it is clear of the inlet
ring.
ATTENTION: The fan assembly must be radially centered. Use a feeler gauge or
similar tool to measure the gap between the impeller shroud and inlet ring. The
gap must be at least 0.25 in. (6.35 mm). To adjust the gap space, loosen the
hardware connecting the inlet ring to the cabinet plate and adjust the inlet ring
as necessary.
