3.10 STARTING PROCEDURES
3.11
Starting a Cole-Parmer Air Admiral
Before attaching the pump to a system, familiarize yourself with the function and action of the
Air Admiral
Vacuum/Pressure Station that you have acquired. Review the power requirements as
®
described in Section 2.60. Cole-Parmer recommends running the pump for a few minutes to warm it up,
before use. The warm-up improves the pumps ability to handle humid air. Set the device on a level,
sturdy surface so the controls can be easily reached and adjusted.
1.
Be sure that the power switch is in the OFF (down) position. Plug in the device and turn the
switch to the ON (up) position.
2.
Block the intake hose barb and allow the gauge to reach stable vacuum level.
3.
Set vacuum level by turning the regulator knob counter-clockwise to increase vacuum or
clockwise to decrease vacuum..
Note: This procedure should be performed each time you use this device.
3.12
Cleaning The Device
1.
Make sure the ON/OFF switch is in the OFF (down) position.
2.
Unplug the device from the wall outlet and allow suction level to drop.
3.
Remove the application tube from the intake port.
4.
Wipe the outside of the case with a clean, damp cloth after each use.
3.20 LEAK DETECTION
3.21
The importance of eliminating all leaks in a vacuum system is obvious. The pump must remove this
added volume of leaked gas to maintain the desired vacuum. Leaks for these pumps can be located by
slightly pressuring the system and painting the suspected area with a thick soap solution. Escaping air
will produce soap bubbles.
3.30 OPERATING PRESSURE RANGE
3.31
Air Admiral
Vacuum/Pressure Stations are designed to be run from slightly below atmospheric to their
®
maximum vacuum level on the intake side. The pumps also may be run from atmospheric to their
maximum rated pressure rating. Consult the Specification Table for the ratings of
your specific model (See Section 6, Specifications).
3.40 SHUTDOWN PROCEDURES
3.41
After use, Cole-Parmer recommends the pump be run for about 2 minutes disconnected from the
vacuum process. The air pumped through the mechanism will purge out water vapor or droplets of water
condensate that may have formed on the inside of the pump. This purge of the pump mechanism helps
prevent corrosion.
