4. Inspect the system being tested by shining an ultraviolet inspection
lamp (blacklight) over the suspected leak areas. The origin of the leak
can quickly be identified by the bright yellow-green fluorescent glow.
5. After inspection and repair, the additives may remain in the system
without harm to engine parts or diminished lubrication, to identify
potential future leaks.
A-670Plus, A-671Plus and A-672Plus
AIR CONDITIONING ADDITIVE
Reveal A-670Plus is designed for instant leak detection of Freon in mineral
oil lubricated automotive air conditioning systems. This product is designed
for use with the AC-1 injector.
Reveal A-671Plus is designed for instant leak detection of R-134a in PAG
lubricated air automotive conditioning systems. This product is designed for
use with the AC-2 injector.
A-672Plus is designed for use in Ester Oil, PAG Oil Mineral Oil and low
temperature Alkyl Benzene Systems: R-11, 12, 22, 113, 114, 123, 134A, 500,
HP-62, A-Z50, AC-9000 & A-220. A-672Plus Meets ASRAE Test Standards
86 & 97 and comes in a convenient six-pack of one-ounce containers.
Both A-670Plus and A-671Plus come in one-ounce bottles. Each bottle
contains four 1/4-oz. applications (reference increment marks on bottle).
USE INSTRUCTIONS
NOTE: The injector should always be used in a vertical position with the
valve end down (refer to Figure A).
1. Dilution: 1/4 oz. per air conditioning system. Pour one application (1/4
oz.) of A/C additive into its corresponding oil injector.
2. With the engine and refrigeration system OFF and all valves closed,
connect the injector to the refrigerant supply and to the low-pressure
service valve.
3. To purge the injector, open the refrigerant supply valve and slowly crack
open the injector cylinder. When you hear refrigerant escaping, close
the cylinder. The injector is now purged of air.
4. With the engine and air-condition system ON, open the refrigerant
valve. Slowly open the injector valve allowing refrigerant to charge
additive into the system. Charging requires no more than 2 to 3 ounces
of refrigerant. Continue charging the system with just enough refrigerant
to test the system.
5. Close all valves and disconnect the injector from the system.
6. Run the system on HIGH for 5 to 6 minutes, or long enough to allow the
additive to circulate.
7.
Search the surface of the air conditioning system with a blacklight lamp.
The origin of the leak can quickly be identified by a bright yellow-green
fluorescent glow.
8. After repairs have been made, recharge the system with refrigerant and
re-inspect following these steps.
A-670Plus and A-671Plus are system friendly. Both additives safely remain in
the air conditioning system to identify potential future refrigerant leaks.
Add appropriate amount of Dye to system and allow to operate under normal
conditions for a short period. Longer operation may be required if leak is minimal.
Operate Ultraviolet light in the suspected area and a green glow will appear at the leak
source. Dye ratio to system is based on 1/4 oz. per typical automotive applications or
1/4 oz. up to 2.9 lbs. of refrigerant. Add 1/2 oz. from 2.9 lbs. to 25 lbs. of refrigerant.
On systems of 25 lbs. of refrigerant or more, add 1/2 oz. per every 4 gallons of
lubricant.
