RECEIVING INSPECTION
Check for damage or missing parts immediately upon receipt. Ensure that wheel rotates freely.
REPORT ANY DAMAGE PROMPTLY TO CARRIER.
INSTALLATION
9200 series blowers are suitable for suspension or base mounting.
SUSPENSION MOUNTING
Drill 4 - 7/8" diameter holes through the top using the inside top "hat section" channel as a guide. Extend 1/2" diameter threaded
mounting rod through the cabinet and the bottom channel and secure to both top and bottom. Ensure unit is level.
BASE MOUNTING
For base mounting secure unit through 4 - 7/8" diameter holes located in the "hat section" channel in the bottom of the unit. Ensure
unit is level.
Excessive belt tension is the number 1 cause of
blower bearing failure.
Proper belt tension and pulley alignment are
essential for trouble free operation.
A simple "Rule of Thumb" for checking belt
tension is illustrated.
When the belt is grasped as shown, a total
deflection of approximately 1" should be easily
attained.
Insufficient deflection indicates that the belt is
too tight, resulting in noise from excessive
vibration, premature bearing failure, and short
belt life. Tight belts may overload a motor that
would otherwise be adequate.
Excessive deflection is an indication that the belt
is not tight enough. If not corrected, slippage
could cause loss of blower speed and belt
failure through wear.
A belt should be just tight enough to avoid
slippage.
Align pulleys with a straight edge to conserve
belt life and eliminate unnecessary noise.
Check tension before start-up, after every pulley
adjustment and regularly thereafter.
SET SCREWS
Ensure all set screws on both pulleys and the
blower wheel are tight.
