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. Raise the drainplug by tilting the unit. 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 YOUR SKIN.
7. Lower the unit and 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 HydroFlame Torch
to resume use.
