40 Operating Your Ultrasonic Bath
Optimizing Your Ultrasonic Bath
Tanks
Cleaning - check the tank for contamination whenever you change
solution. If necessary, remove contaminants with a nonabrasive cloth and
water.
Emptying - always unplug the unit before emptying the tank. Empty the
solution into a waste disposal unit.
Filling - always unplug the line cord before filling the tank. Fill the tank to
the operating level (with beaker/tray in place), using warm tap water.
Low solution level - will cause the unit to fail. When you remove heavy
or bulky loads from the tank, the solution level may drop below the
operating level. If so, be sure to replace lost solution and degas, if
necessary, depending on the amount used.
Overload - do not rest any items on the tank bottom. Weight on the tank
bottom dampens sound energy and will cause damage to the transducer.
Instead, use a tray and/or beaker positioning cover to support all items.
Allow at least 1 inch (2.5 cm) between the tank bottom and the beaker or
receptacle for adequate cavitation.
Covers - allow the unit to heat up faster, to a higher temperature, and
avoid excessive liquid evaporation. However, obstructing the cover vents
will cause the unit to overheat.
Temperature
Heater - the heater may cause some discoloration of the tank wall. This is
normal and will not affect the performance of the unit.
Solution - the fastest method to heat your ultrasonic bath is to fill with
warm solution, use heat, ultrasonics (which also adds heat), and a cover.
Over temperature protection (CPXH only) - the unit will shut down at
75 °C (167 °F) and display will go blank with only the Alarm icon
remaining on. Turn the unit off and allow it to cool down. For a faster
cooldown, replace some of the warm solution with cold solution.
