Procedure Guide > FOR R-134a SYSTEMS & RETROFITTING
PROPER USE OF SSR-134a KITS
AND
RETROFITTING FROM R-12 TO R-134a
PROFESSIONAL USE ONLY BY CERTIFIED 609 TRAINED PERSONNEL.
ALWAYS WEAR SAFETY GOGGLES WHEN WORKING WITH REFRIGERANTS.
DO NOT INHALE VAPORS. AVOID CONTACT WITH SKIN AND EYES
NOTE: SSR R-134a Kit will seal leaks in systems of up to 4 lbs. refrigerant charge. Larger systems will require an additional kit for each 4 lbs. of refrigerant charge. (When charging larger than a 4 lb system, add cans of Tune-Air® sequentially before adding cans of Cryoseal® sealant to system).
The SSR R-134a Kit contains TWO 4 oz. cans. 1 can Cryoseal® (sealant), 1 can Tune-Air® (dehydrant).
NOTE: SSR KITS WILL NOT SEAL COMPRESSOR SHAFT SEAL LEAKS. Carefully check shaft seal for leaks and replace if any leakage is found before using SSR R-134a Kit. Also check compressor for proper operation.
LOSS OF LUBE OIL THRU LEAKAGE MAY HAVE CAUSED COMPRESSOR AND/OR SHAFT-SEAL DAMAGE.
DIRECTIONS
- If A/C system has lost its entire charge, inspect system for obvious leaks and ruptures. With engine and A/C off, depressurize air conditioning system into recovery unit.
- Replace drier/accumulator (XH-9 TYPE) and replace Schrader Valves, Expansion Tube or "H" valve. (in dual systems both front and back must be replaced, i.e. Vans, Buses,RV's)
- Evacuate A/C system for 5 minutes only to remove air. NOTE: If you cannot reach 29" vacuum within 5 minutes, and hold above 25" for 5 minutes the hole is too large to seal.
- ADD APPROPRIATE AMOUNT OF OIL to compensate for leakage (2-4 ounces) NOTE: If you are RETROFITTING the R-12 system to R-134a, then add 6-8 oz. of PAG or POE lubricant to the system.
-
- Add appropriate amount of R-134a refrigerant to system. NOTE:
Full charge, less 8 ounces for kit charge. If retrofitting from R-12 to R-134a use only 85% of R-12 capacity for the R-134a total charge,
less 8 ounces for kit charge, also apply R-134a label and fittings.
- With A/C system revving at approximately 1500 RPM, slowly add
the 4 oz. can of Tune-Air® (#1 can) to LOW side in LIQUID state.
(For systems larger than 4 lbs. add an additional can of Tune-Air® for each 4 lb. capacity). Add SLOWLY by rotating can up and down to avoid slugging the compressor. Allow system to run for 20 minutes before adding Cryoseal®
- With A/C system running, slowly top off with the 4 oz. can of Cryoseal® (#2 can) in LIQUID state to LOW side of system. ( For a system larger than 4 pounds, add an additional can of Cryoseal®for each 4 lb. capacity.) Allow A/C system to run in order to circulate SSR to seal all leaks. NOTE: In the event the refrigerant in this system is recycled, the Cryoseal® will separate out with the oil during recycling, therefore a new SSR R-134a Kit should be added to the system to protect against moisture and future leaks.
