BLOWER STARTUP CHECKLIST
This startup procedure should be followed during the initial installation and after any shutdown periods or after the
blower has been worked on or moved to a new location. It is suggested that the steps be followed in sequence
and checked off (
) in the boxes provided.
1.
Check the unit and all piping for foreign material and clean if required.
2.
Check the flatness of the feet and the alignment of the drive. Feet that are bolted down in a bind
can cause housing distortion and internal rubbing. Misaligned V -
-
- drives can cause the rotors to rub
against the headplates and cause a reduction in the volumetric efficiency of the unit. Misaligned
couplings can ruin bearings.
3.
If the blower is V -
-
- belt driven, check the belt tension and alignment. Over -
-
- tensioned belts create
heavy bearing/shaft loads which lead to premature failure.
4.
Be sure adequate drive guards are in place to protect the operator from severe personal injury from
incidental contact.
5.
Check the unit for proper lubrication. Proper oil level cannot be over -
-
- emphasized. Too little oil will
ruin bearings and gears. Too much oil will cause overheating and can ruin gears and cause other
damage. Insure that grease lubricated bearings are properly lubricated.
6.
Turn the driveshaft by hand to be certain the rotors do not bind.
7.
“Jog” the unit with the motor a few times to check that rotation is in the proper direction, and to be
certain it turns freely and smoothly.
8.
Start the unit and operate 15 minutes at no load. During this time, check for hot spots and other
indications of interference.
9.
Apply the load and observe the operation of the unit for one hour. Check frequently during the first
day of operation.
10.
If malfunctions occur, do not continue to operate. Problems such as knocking rotors can cause
serious damage if the unit is operated without correction.
