GENERAL INSTRUCTIONS
A refrigeration system suspected of an
acidic lubricant condition should be
tested to determine if it is within an
acceptable limit before extensive damage
is done and/or hermetic motor burnout
occurs.
The Acid Test Kit is a simple and direct
service tool that “takes the guesswork out
of service work.” The test can be done in
the field, or service shop to determine if
the acid content of the lubricant is within
safe operational limits.
After mixing the solutions and adding
the lubricant, the color should be judged
immediately. Allowing the solution to set
an hour or more may give a false reading.
The chart shows the color change points
of the TA-1 Acid Test Kit with mineral,
alkylbenzene, and POE lubricant.
The solutions in the kit are stable, but are
sensitive to light and heat. Store the kit, in
the product box, in a cool, dry place.

THE TA1 ACID TEST KIT
OFFERS THESE OUTSTANDING
BENEFITS:
BUilds cUstomer confidence
Show the test results of the acid test kit
to customers, or perform the test in their
presence. In this way they realize you
are using the most up-to-date scientific
method for system maintenance. Showing
customers the test results will also help
to convince them to spend the money
necessary to do a proper clean-up job.
Customers who are thoroughly confident
of your abilities will be more interested
in establishing preventive maintenance
programs.
Acid Test Kit
Tests Mineral, Alkylbenzene, and POE Lubricants
- Thoroughly Field Proven
- Takes the Guesswork Out of Service Work
accUrate
and reliaBle
Using a simple, scientific method, you
can precisely measure the amount of
acid in a lubricant sample taken from a
contaminated system. The test proce-
dure has been proven by extensive field
experience.
convenient
The TA-1 is simple and convenient to
use. The kit has pre-measured solutions
supplied in bottles with screw caps for
easy handling. The kit may be used on
the job site, or a lubricant sample can be
saved and tested in the presence of the
equipment owner.
lUBricant sample Used for test
Since lubricant is the scavenger, it gives
the best indication of acid in the system.
Less than an ounce of lubricant is
required.
QUick to Use
Once the lubricant sample is obtained…it
will take only minutes to perform the test.
Simply mix the solutions and lubricant to
be tested. Shake, and the resulting color
tells the complete story.
cost
The TA-1 kit is a very inexpensive way
to assess the vulnerability of expensive
system components to harmful acidic
conditions.
The TA-1 Kit is designed to serve as a
guideline for testing POE lubricants
since the industry has not established a
maximum acid level for POE lubricants.
Always follow the equipment manufac-
turer’s recommendations.
The TA-1 kit should not be used on sys-
tems that contain a lubricant additive
leak detector. The additives can inter-
fere with the color change point of the
acid test kit.
centrifUgal systems
Most of the lubricants used in centrifugal
systems contain additives. These addi-
tives react like an acid even though the
lubricant is not contaminated. Therefore,
the TA-1 cannot be used to test many
centrifugal lubricants. However, the kit
can be used to test certain refrigerants
themselves. Refrigerants 11, 113 or 123
from these systems can be tested directly.
This permits routine maintenance and a
check on the system following clean-up of
a contaminated system.
