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 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 impellers 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 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.
6.
With motor electrical power locked out and disconnected, turn the drive shaft by hand to
be certain the impellers 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.
The internal surfaces of all Gardner Denver units are mist sprayed with a rust preventive
to protect the machine during the shipping and installation period. This film should be
removed upon initial startup.
9.
Start the unit and operate 15 minutes at no load. During this time, check for hot spots
and other indications of interference.
10.
Apply the load and observe the operation of the unit for one hour. Check frequently
during the first day of operation.
11.
If malfunctions occur, do not continue to operate. Problems such as knocking rotors can
cause serious damage if the unit is operated without correction.
