17 Operating Your Cleaner
Over temperature protection (C-only)
- the cleaner will shut down at
75ºC and the LED display will blink “75”. Turn the cleaner off and allow it
to cool down. For a faster cooldown, replace some of the warm solution
with cold solution.
Solution
Solution activity
- the amount of visible activity is not necessarily related
to optimum cavitation for cleaning.
Degassing
- fresh solutions contain many dissolved gases (usually air),
which reduce effective ultrasonic action. Although solutions will naturally
degas over time, using Degas mode speeds up the degassing process.
Solutions that have been sitting unused for 24 hours or longer have
reabsorbed some gases.
Heat
- increases the chemical activity of cleaning solutions.
Surface tension
- can be reduced by adding solution to the bath.
Reduced surface tension will increase cavitation intensity and enhance
cleaning.
Solvents
- never use solvents. Vapors of flammable solutions will collect
under the cleaner, where ignition is possible from electrical components.
Renewal
- replace cleaning solutions often to increase ultrasonic
cleaning activity. Solutions, as with most chemicals, will become
depleted over time. Solutions can become contaminated with suspended
soil particles which coat the tank bottom, inhibiting ultrasonic activity.
