Safety Precautions Before using your Ultrasonic Cleaner, please read and thoroughly understand these safety precautions. Failure to follow them may result in serious personal injury or property damage. To avoid electrical shock: • Do unplug from power source before filling or emptying the tank. • Do keep the area around the cleaner clean and dry -- wipe up solution which spills over the tank brim. Water and high voltage can cause electrical shock. • Do not operate the cleaner without proper grounding.
To prevent damage to the cleaner: • Do change your solution regularly. • Do not operate the cleaner dry. • Do not place parts or containers directly on the bottom of the cleaning tank; use a basket or other device to suspend items. Failure to comply may cause transducer damage and will void your warranty. • Do not allow the cleaning solution level to drop more than four inches below the top of the tank with heat or ultrasonics on.
Introduction DHA-1000 General Information This DHA-1000 ultrasonic cleaner is a self-contained unit which consists of a powerful ultrasonic generator, a stainless steel cleaning tank and an array of durable industrial style 44 kHz transducers. These transducers provide increased cleaning power and ensure uniform cleaning activity throughout the bath. The unit includes heaters and controls to raise the bath temperature for improved cleaning activity.
Accessories For Your Cleaner A stainless steel cover and a parts cleaning basket are available for your DHA-1000. Description Part Number Stainless Steel Cover 100-246-802 Stainless Steel Parts Basket CPN-916-032 Consult your distributor for price and delivery. Unpacking Your Cleaner Please check your cleaner and its carton carefully for any external or internal damage. If you find damage, contact your shipping carrier immediately, before contacting your distributor.

How Ultrasonic Cleaning Works Ultrasonic sound is sound transmitted at frequencies generally beyond the range of human hearing. In your ultrasonic cleaner, ultrasonic sound (sonics) is used for cleaning materials and parts. This is how it works: As the sound waves from the transducer radiate through the solution in the tank, they cause alternating high and low pressure areas in the solution. During the low pressure stage, millions of microscopic bubbles form and grow. This process is called CAVITATION.
Operating Your Cleaner If this is the first time you are using the cleaner, please read this whole section before proceeding. Before You Start Cleaning CAUTION • Do not place parts or containers directly on the bottom of the cleaning tanks; use a basket or other device to suspend items. • Do not allow the cleaning solution level to drop more than four inches below the top of the tank with the cleaner on. • Do not ever use alcohol, gasoline or flammable solutions. Doing so could cause a fire or explosion.
Getting Ready Step 1 2 3 4 5 Action Select your cleaning chemistry (check with your chemical supplier for solution effects on metals). Allowing for the volume of the parts you will be cleaning and cleaning chemistry, fill the tank with warm tap water to the operating level (two to four inches from the top). Add cleaning chemistry to the tank water. Plug the cleaner into a grounded outlet. For maximum efficiency, refer to page 9, “Optimizing Your Cleaner” before proceeding.
Optimizing Your Cleaner 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 cleaner before emptying the tank. Empty the solution into a proper waste disposal unit. Filling - always unplug the line cord before filling the tank. Fill the cleaner to the operating level (1-2 inches from the top) using warm tap water. Low solution level - will cause the cleaner to fail.
Application Hints First time cleaning - first experiment with one piece, then proceed with the remainder. Solution level - Be sure to maintain solution level within one or two inches of the tank top. Surface activity can vary with liquid level. Load size - It is faster and more efficient to run several small loads rather than a few big loads. Placing items - Never allow items to sit on the bottom of the tank. Always place them in a basket or suspend in the solution.
Cleaning Solutions CAUTION Do not use alcohol, gasoline, bleach, mineral acids, solutions with a flash point, semi-aqueous or combustible liquids in ultrasonic tanks, or you will void the warranty. Only use non-flammable and water-based solutions. Solution Types Water-based solutions are either slightly acidic or alkaline. They include detergents, soaps and industrial cleaners designed to remove specific soils. Acidic water-based solutions: remove rust, tarnish or scale.
Change the cleaning solution periodically. Cleaning solutions can become contaminated with soil particles which coat the tank bottom. This coating dampens the ultrasonic action and reduces cleaning efficiency. Certain solutions will cavitate better than others. Contact your local distributor for further information. Heat and cavitation: increase the chemical activity of cleaning solutions. Some materials may be damaged by this stronger chemical action. When in doubt, test run samples of items to be cleaned.
Troubleshooting If your cleaner does not operate satisfactorily, please check the tables below for possible causes before calling your authorized service center. WARNING High voltage inside - dangerous shock hazard. DO NOT attempt to disassemble or repair the cleaner. Problem Cleaner will not start. Cause Cleaner not plugged in properly. Circuit board fuse blown Cleaner operates but does not heat solution Decreased ultrasonic activity. Heater malfunctions. Solution is not degassed.
Performance Check your cleaner periodically to test the level of activity of the ultrasonic cavitation. Frequency of testing will depend on your use of the cleaner, however, we suggest running this test monthly. Glass Slide Test You will need the following equipment: • Frosted microscope glass slide (1” x 3”), such as ESCO #2951F, or equivalent; • No. 2 lead pencil; and • General purpose dish detergent or liquid soap. Test procedure: 1.
The ultrasonics will begin immediately to remove the lead from the slide. All lead should be removed within 10 seconds. If your cleaner passes this test, its ultrasonic cavitation is acceptable. NOTE: To ensure consistency from test to test, be sure to repeat test conditions - use the same solution concentration, liquid level, temperature, type of pencil, length of degassing, etc. Service With normal use, your Ultrasonic Cleaner should not require servicing.
