| CHANGING THE ELECTROLYTE SOLUTION |
Depending on your use, the electrolyte may last for up to 1 year. We recommend changing the electrolyte at least each year to keep the unit operating at peak performance. When changing the electrolyte, the flux solution and filter material also must be changed. You will know the electrolyte needs to be changed when:
- The flame becomes weaker
- The pressure drops
- The unit does not generate any gas
YOU WILL NEED:
| Rubber gloves |
Turkey baster or large syringe |
| Eye protection |
1 quart of electrolyte* |
| Protection for your clothing |
Clean filter material* |
| Drop cloth or safe work area |
Fresh flux* |
| Plastic bucket |
Replacement rear check valve* |
| Plastic funnel |
Warm distilled water |
*All replacement parts are available through the distributor from whom you purchased your HydroFlux Welder.
CHANGING THE SOLUTION
**CAUTION**
The electrolyte is highly caustic and should always be handled using protective equipment such as rubber gloves and safety glasses or goggles. When handling the electrolyte solution, be careful not to spill any. The electrolyte may damage any finished surfaces, clothing, etc. Electrolyte is highly corrosive to many metals, including copper, brass, zinc and aluminum, and reacts violently with acids. Electrolyte destroys human tissue on contact. It is odorless and colorless.
1. |
Unplug the unit. Put on protective equipment. |
| 2. |
Remove all caps. |
| 3. |
Use the turkey baster to remove all flux and discard in accordance with all applicable regulations. Wipe the inside of the chamber dry. |
| 4. |
Remove all dryer filter material and discard. If there is any moisture in the dryer chamber suction it out and wipe dry. |
| 5. |
Place the plastic bucket under the drain plug. If possible, place the bucket close enough to avoid splashing. The electrolyte is a highly caustic material. See the MSDS at the end of this manual for safety and health precautions. |
| 6. |
Open the drain plug with the wrench or pliers. Take care that the plug does not fall into the bucket. After a few turns with the wrench it should be only finger-tight. Remove the plug. It is EXTREMELY IMPORTANT THAT YOU WEAR SAFETY GLASSES, GLOVES AND PROTECTION FOR YOUR CLOTING DURING THIS STEP! ELECTROLYTE IS CAUSTIC AND WILL IMMEDIATELY DAMAGE YOU SKIN. |
| 7. |
Allow the chamber to drain. The electrolyte should be a muddy-brown to black color. Tip the unit slightly to facilitate draining. |
| 8. |
With the drain still open, slowly pour approximately one quart of warm distilled water through the electrolyte chamber. Allow it to run through the unit and into the bucket. Repeat until the water is reasonably clear. |
| 9. |
Replace the drain plug and tighten. The plug should be tightened to finger tight plus an additional 1/4 turn. The drain plug "O" ring can be damaged easily if the plug is too tight. |
| 10. |
Remove the cover of the unit. |
| 11. |
Carefully disconnect the clear tube that connects the flux chamber to the outside wall of the overflow reservoir. Drain any remaining flux from this tube. Replace the cover. |
| 12. |
Replace the rear check valve filter by disconnecting the tubing from both ends and inserting a new filter. |
| 13. |
Disconnect the tubing from the base of the handpiece. Unscrew the base of the handpiece at the black "O" ring. Tap out the gray sintered metal check valve filter and clean in an ultrasonic or steam cleaner. |
| 14. |
Replace dryer filter material, taking care to pack it firmly, but not tightly. Check the inside gasket on the cap for cracks or tears. Replace if necessary. |
| 15. |
Refill flux chamber to the halfway mark between minimum and maximum. Check the inside gasket on the cap for cracks or tears. Replace if necessary. |
| 16. |
Using the plastic funnel, slowly fill the distilled water chamber with electrolyte. Check the inside gasket on the cap for cracks or tears. Replace if necessary. |
| 17. |
Refer back to the sections on Setting-up Your Unit and Using the HydroFlux Welder to resume use. |
