ROTARY POSITIVE BLOWERS
INSTALLATION AND LUBRICATION
BLOWER STARTUP CHECKLIST
This start-up procedure should be follower during initial installation and after any shutdown period
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 level and alignment of the drive. 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. Check the unit for proper lubrication. Proper oil level cannot be overemphasized. Too little oil will
ruin bearings and gears. Too much oil will cause overheating and can ruin gears and cause other
damage.
4. Turn the unit over by hand to be certain it does not bind.
5.
“Jog” the unit with the motor a few times to check rotation and to be certain it turns freely and
smoothly.
6. Start the unit and operate for 15 minutes at no load. During this time, check for hot spots and
other indications of interference. If minor hot spots occur, introduce a small amount of lubricating
oil into the blower inlet while it is operating. Repeat until hotspots disappear. Once hot spots have
been removed, it is unnecessary to lubricate the impeller chamber for proper performance.
7. Apply the load and observe the operation of the unit for one hour. Check frequently during the
first day of operation
8. If malfunctions occur, do not continue to operate. Minor problems, such as knocking impellers,
can cause serious damage if the unit is operated without correction.
9. Fill in and return warranty card.
