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.
V
1.
Check to make certain that the blower has been properly lubricated with AEON PD Synthetic
Blower Lubricant. Proper oil level cannot be overemphasized. Too little oil will ruin bearings and
gears. Too much oil will overheat the lubricant and lead to serious blower damage.
V
2.
Check to make sure all oil sump breather filters are installed in their proper location. Oil leakage
will occur if they are improperly located.
V
3.
Check the unit and all piping for foreign material and clean if required.
V
4.
Check the inlet or inline filter to make sure it is not plugged causing dangerous inlet restriction.
V
5.
Check the preload of the feet and the alignment of the drive. Feet that are bolted down in a bind
can cause case distortion and internal rubbing. A misaligned V--belt drive will reduce belt life. Misa-
ligned couplings place heavy loads on bearings which leads to their premature failure.
V
6.
If blower is V--belt driven, check the belt tension. Over--tensioned belts create heavy bearing loads
which lead to premature bearing failure.
V
7.
If blower is V--belt driven, check for excessive overhung load condition. Loads in excess of maxi-
mum allowable overhung load limitations will lead to premature bearing failure and shaft breakage.
V
8.
Be sure adequate drive guards are in place to protect the operator from SEVERE PERSONAL
INJURY from contact with rotating components.
V
9.
Turn the unit over by hand to be sure there is no binding or rotor contact. The 45 series uses piston
rings for sealing. When units are new, some resistance to turning the driveshaft by hand will be
encountered. After several hours of running, this seal pressure will relieve itself and the blower will
be somewhat easier to turn.
V
10.
Jog the blower with the motor to check for proper rotation and airflow direction. Listen for unusual
noise coming from the blower or motor and make sure the blower coasts smoothly to a stop.
V
11.
Start unit and operate for 15 minutes with no load. Check for hot spots on housing or end plates,
noise and other indications of interference. Allow the blower to cool to room temperature and
re--check oil level. Add oil if necessary. DO NOT OVERFILL.
V
12.
Check to be certain that actual blower speed is within allowable limits.
V
13. Apply load and observe operation for the first hour, checking pressure and air discharge temper-
ature:
(a) Do not operate blower over manufacturer’s specified pressure or vacuum rating.
(b) Discharge air temperature should not exceed the maximum allowable temperature.
V
14.
Check and retension belts after the first few hours of operation to minimize slippage and belt wear.
DO NOT OVERTENSION.
V
15.
If mechanical problems are encountered during installation or start--up, notify your nearest
DuroFlow Distributor. Never continue to operate your DuroFlow blower if you detect a malfunction,
as serious damage can occur.
Do not attempt any internal investigation without factory
authorization since this will void the warranty.
