Important Steps Of Initial Start-Up; Vacuum Tips For Best Performance - yellow jacket BULLET X Operation And Maintenance Manual

Important Steps of Initial Start-Up

1. Make sure motor is off and name plate
voltage on motor bottom matches outlet
voltage. (See page 6 for voltage power
conversion if voltage mismatch exists)
2. Remove oil fill cap on pump cover.
Fill with YELLOW JACKET
Pump Oil until oil level is even with oil
level line.
3. Stay clear of the oil fill/exhaust port!
Remove intake cap to open intake to
the atmosphere and then switch on
the motor. When pump reaches running
speed, replace cap.
4. To check the pump's performance,
attach a micron gauge to the 1/4" male
flare fitting, making sure that the intake
fitting is capped. Turn on the pump. The
micron gauge will display the ultimate
vacuum reached.

Vacuum Tips for Best Performance

Quick Tips:
1. For the fastest vacuum, connect your
pump directly to the system. Going
through a manifold slows the job.
2. Use as large of a hose as possible, even
though the system has 1/4" fittings. A
1/2" or 3/8" hose allows a much faster
and more complete vacuum.
3. Use as short of a hose as practical to
get maximum evacuation speed. Short
hoses make evacuation faster than
longer hoses. Long hoses slow the
process.
4. Metal hoses are the most impervious
so will be most effective in evacuation.
5. Evacuate through both high and low
sides at the same time to speed up
evacuation.
