ULTRASONIC CLEANING SETUP
WARNING
D O NOT OPERATE THE ULTRASONIC GENERATOR WITHOUT LIQUID IN THE ULTRASONIC TANK . P ERMANENT
DAMAGE WILL RESULT IF THE SYSTEM IS RUN DRY . T HIS SYSTEM REQUIRES A MINIMUM OF 12 INCHES OF LIQUID TO
PROTECT THE HEATERS AND ULTRASONIC TRANSDUCERS .
Filling the Unit - Check to be sure the drain valve (located on the inside the drain access door) to insure it is tightly
closed. Fill the tank with 13” (approximately 24 gallons) of warm to hot water. Warm water increases the efficiency of
the cleaning process; with the optimum water temperature being 90 - 100
° F some chemicals will require higher
temperatures for proper cleaning.
Adding Chemicals - Depending upon the chemical makeup of the water supply in your area, you may start by
adding a slightly reduced amount of chemical as recommended by the manufacturer. After cleaning one or two items,
you may choose to increase the chemical ratio. The amount of chemical will be based on the condition of the water
being used and how much contamination is to be removed. Detergents that are used in this ultrasonic cleaning system
must be compatible with 304 and 316L stainless steel. You will void the warranty if chemical attack to the
stainless steel occurs.
Power On - Engage the ultrasonic start switch. The ultrasonic generators will start the ultrasonic action in the tank.
Both generator circuits are controlled by switch on the control panel.
System Degassing – At startup or after fluid changes, the unit has to be run to eliminate air in the fluid before parts
washing. The system should be run for approximately 10 minutes with the ultrasonic generators at full power an tank
termperature at 100 F to allow the water in the cleaning tank to properly degas. Typically, the sound of the unit in
operation will change from a high pitch “squeal” to a lower tone when de-gassing is completed. (The de-gassing
process removes unwanted air molecules from the cleaning tank, thus maximizing the efficiency of the
cavitation/cleaning process.)
Cleaning - Place materials to be cleaned into the degassed cleaning tank. Be sure that all parts and components are
fully submerged into the cleaning solution. Check to be sure that no air pockets are present on the item(s) being
cleaned, as the cavitation process will only operate in the liquid solution. Some initial testing will allow you to determine
the proper settings for the optimum time and temperature. Also discuss the application with the chemical supplier.
Typically, due to the extreme efficiency of the unit, only 2 to 3 minutes of immersion time is required to thoroughly
clean the average job.
WARNING
When first learning the capabilities of this system, do not leave items unattended in the wash tank for periods
longer than four (4) minutes! The system may damage surfaces if allowed to remain in the ultrasonic bath for
extended periods of time! Longer cleaning times can be used after thorough testing has been completed.
Do not place items to be cleaned directly on the tank bottom. Always suspend parts or use baskets that place the
weight of the parts on the edges of the ultrasonic tank. Do not attempt to clean aluminum in a caustic solution. Do not
use bleach or ammonia as a cleaning chemical.
