Caution
To avoid property damage
or personal injury, always
try rotating the fan by HAND
prior to connecting the
unit to the power source.
Check for suction at the air
inlet port by placing your
finger over the port as you
turn the fan. You should
feel a slight suction with
each rotation of the fan. If
you don’t feel suction, or if
you feel or hear a thump as
you turn the fan, DO NOT
CONNECT THE UNIT TO A
POWER SOURCE; review
the assembly procedure for
possible error.

mounting holes in the compressor housing.
