Pro-Flush
The Pro-Flush
Kit consists of a reusable injection tank (with built-in 200 PSI pressure relief
®
valve), nitrogen charging hose, injection tool assembly and one 8 oz. can of Pro-Flush
The trigger injector on the tool assembly assures more efficient use of the solvent by allowing
infinite control of the flushes rather than the less efficient method of flushing in one long burst.
The Pro-Flush
Solvent is a dual purpose blend designed to clean line sets in preparation of
®
changing from R-22 to R-410A (mineral oil to POE oil) as well as to flush the contaminants from
a system after a compressor burn out. Typically, due to the high acidic level of contamination
in a burn out, more solvent will be required in system flushes than in line set flushes. The
Pro-Flush
Solvent conforms to the EPA Significant New Alternatives Program (SNAP) and is
®
non-ozone depleting and low-toxicity.
Compressor Burnouts
I. Equipment Required
1. Pro-Flush
Kit including one 8 oz. can of Pro-Flush
®
capacity.
2. Re-sealable container to hold the contaminated flush material.
3. Nitrogen tank with regulator.
4. Vacuum pump with accessories.
5. Absorbent shop cloths, rubber gloves and safety goggles.
II. Detailed Instructions
1. Evacuate the system using approved techniques and recovery equipment.
2. Take the electrical system off-line.
3. Remove the old compressor from the system.
4. Remove filter drier cores as well as any check valves and reversing valves on heat
pumps. It may be faster and less expensive to by-pass the filter drier, check and reversing
valves with a bypass loop.
5. Make sure a resealable waste container is attached to a discharge port to capture the
flushed acidic contaminants.
6. To maximize solvent contact time, restrict the flow at the discharge port. This will
minimize the amount of solvent needed to thoroughly clean the system.
7. Attach the hose and injector tool assembly to the outlet side of the pressure tank. Fill the
Pro-Flush
Injector pressure tank with Pro-Flush
®
24 oz. of Pro-Flush
(ball valve) side of the injector tank (fig. A, page 3).
8. Set the nitrogen gauge at 50 PSI, open the regulator valve on the nitrogen tank then
slowly open the valve on the injector tank to pressurize it. DO NOT EXCEED 200 PSI.
9. Close the valve on the injector tank and nitrogen tank and then disconnect the nitroge
hose from the injection tank.
10. Insert the rubber adapter in the inlet port (fig. B, page 4), maintaining the injector tank in
an upright position. Inject Pro-Flush
(2-3 oz./ton). The number of flushes will depend on the size of the system and the
contamination level.
11. Connect the hose from the nitrogen tank to the inlet port of the part that is being flushed
and purge the system at 150 PSI for 1-2 minutes. This will assure removal of all trace
amounts of oil residue and solvents. Check the solvent at the outlet port to be sure all
contaminants have been purged from the system. If the exiting solvent is not yet clear
repeat steps 10 and 11.
12. Next install the new compressor, new filter drier core and check valves. If the system
was bypassed with a loop, remove and reconnect the lines.
13. Using a vacuum pump, evacuate the system to a low micron reading. The typical
evacuation time is approximately 3 minutes per ton.
14. Check the system for leaks, then recharge the system with refrigerant and oil per the
equipment manufacturer's recommendations.
15. Reconnect the electrical circuitry and test the system again following manufacturer
recommendations.
16. Any unused Pro-Flush
use. Ensure all valves are closed on the injection tank to prevent solvent loss during
storage. Dispose of the waste solvent in accordance with local and state waste
disposal regulations.
