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:
•Unplug from power source before filling or emptying the tank.
•Keep the control panel and 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.
•Do not remove the grounding prong on the line cord plug.
•Do not disassemble your cleaner -- high voltage inside the cleaner is dangerous.
•Do not immerse the cleaner in water.
To prevent personal and/or property damage:
•Operate the cleaner with a vented cover or no cover.
•Use water-based solutions.
•Do not ever use alcohol, gasoline, or flammable solutions. Doing so could cause a
fire or explosion and will void your warranty. Use only water-based solutions.
•Do not ever use mineral acids. These could damage the tank.
•Do not touch the stainless-steel tank or cleaning solution -- they may be hot.
•Do not allow fluid temperature to exceed 70°C (160°F).
•Do not place your fingers or hands into the tank while the cleaner is operating. Doing
so may cause discomfort and possible skin irritation. Avoid contact with solutions
and provide adequate ventilation.
•Do not use solutions containing chlorine bleach.
To prevent damage to the cleaner:
•Change your solution regularly.
•Do not cover vents on the housing.
•Do not operate the cleaner dry.
•Do not place parts or containers directly on the bottom of the cleaning tank; use a
tray or wire to suspend items. Failure to comply may cause transducer damage and
will void your warranty.
•Do not allow the solution to drop more than 1½ inch from top of tank with heat or
ultrasonics on. Failure to comply may cause transducer and/or heater damage and
will void your warranty. The fill line is 1” from top of the tank.

Introduction
Ultrasonic Cleaners
These DuraSonic ultrasonic cleaners includes four models with sizes ranging from 11
to 25 liters. Each model is constructed using durable industrial style 40kHz
transducers. These provide increased cleaning power along with built in sweep
frequency to ensure uniform cleaning activity throughout the bath. The five larger sizes
have built in drains. Each model has a digital timer and mechanical thermostat, with a
power switch/fuse in the rear of the machine.
When you first fill your unit, or refill it with fresh solution, use warm water for the
solution. Turn on the heater, set timer and turn on the ultrasonics (press the ON/OFF
touch-screen button, and use the arrow buttons for timing purposes), place the cover,
and the solution will heat to temperature.
Optional Accessories for Your Cleaner
Accessories include a cover and a mesh basket.
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. Please retain your packaging for future use.
Installing Your Cleaner
Check the plate on the back of the cleaner for correct power requirements. Position your
cleaner within easy reach of a standard grounded electrical outlet. Do not place the
cleaner on a circuit which could become overloaded. Connect the Machine to GFI
outlet.
If your cleaner does not operate correctly, first refer to the troubleshooting section for
possible causes, or contact an authorized service center listed at the back of this
manual, for additional information.
