Yellow Jacket 69075 Operating Manual

Why should you care

about Microns?

The answer is simple - if you’re not

pulling a deep vacuum to the low micron

range, the risk of in-warranty failures

and no-charge call backs increases. And

only an electronic gauge is accurate

enough to show when you reach the

necessary micron range suggested by the

system manufacturer.

Why 15 microns or better?

During new system set-up, protective

caps are removed admitting moisture

and air into system components. If air

and moisture remain in the system, they

collect on the high side reducing system

efficiency. This causes a rise in head

pressure. The discharge valve gets hotter

than normal and organic solids form

causing compressor failure.

Moisture in the system can form ice

droplets which close off openings in

expansion valves and cap tubes, and

prevent continuous cooling. Ultimately

moisture, air and heat can produce acids

and sludge which could cause failures.

During service and parts replacement,

the same contaminants can get in again,

and you could be called back for repairs

by a dissatisfied customer.

Moisture and air can even enter through

system leaks. And as the moisture in air

increases, so does the amount of

contamination. The higher the humidity,

the bigger your problem.

A vacuum pump pulls air, moisture and

other contaminants out of the system

before the system is damaged. The

deeper and more complete the vacuum,

the more moisture is removed. That’s

why the YELLOW JACKET®

SuperEvac™ pump is engineered for

deep vacuums of 15 microns or better.

The purpose of manometers

and built-in pump gauges

Manometers provide approximate

readings in inches of mercury. It’s a start

and better than a mechanical gauge for

measuring vacuum but cannot provide

the readings necessary to assure you of

having reached the desired vacuum.

2000 microns, for example, is equivalent

to less than 0.1” of mercury which

would not be readily noticeable on the

manometer or mechanical gauge.

YELLOW JACKET pumps feature a

built-in indicator gauge to monitor

evacuation. When the indicator is in the

green (29” - 30”) range, the gauge is

telling you to

turn on the

YELLOW

JACKET

LCD Vacuum

Gauge for the

more accurate

readings in

the micron

gauge. The LCD reading gives you the

assurance of knowing that the

system is safeguarded with a deep

enough vacuum.
