Introduction
Ultrasonic cleaning takes advantage of a cavitation eect
created by high-frequency vibrations in a liquid medium.
This cavitation effect creates microbubbles that implode
and then burst rapidly and with great force. These bursting
microbubbles create a scrubbing action which can clean
even the hardest to reach areas very eectively.

Safety Information
• Use this device ONLY in accordance with these instructions and for its intended purpose.
DO NOT allow use by children, by anyone who has not read these instructions, or by any
person whose mental or physical condition might prevent safe use.
• ONLY use this device with a stable, compatible, and well-grounded power source. Do not use
3-to-2 prong adapters, ungrounded extension cords, or extension cords of insucient gauge
for this device’s expected electrical load. Do not modify the power plug or move this device
by pulling on its power cord. In case of power loss during operation, unplug it IMMEDIATELY
until power is restored.
• Disconnect this device from its power source while lling up or draining uid.
• DO NOT allow this device to run dry or with excessive fluid. Never fill the tank above the
recommended maximum height mark or within
⅖
inches (1 cm) of the top if there is no such
mark. Never operate the device with less than 1½ inches (3 cm) of uid in the tank.
• DO NOT use volatile solvents with low boiling temperatures. Ultrasonic waves can cause
them to heat up and release fumes.
• DO NOT use this device around ammable, explosive, or corrosive objects or fumes.
• DO NOT get any electrical components wet or operate them with wet hands or in highly
humid environments. If they become wet accidentally, disconnect them from power and allow
time for them to dry completely before further use.
• DO NOT leave this device unattended or its lid open during use.
• DO NOT place any body parts in the tank during use.
• ALWAYS turn o the heating unit manually when cleaning sensitive objects. This unit DOES
NOT automatically deactivate its heating once the target temperature is reached.
• DO NOT remove the lid before or immediately after heating is turned o, as hot steam may
burn your bare skin.
• ALWAYS disconnect this device from its power source before any cleaning, maintenance, or
repair.
• DO NOT operate this device if it malfunctions or shows signs of damage. Repair or replace
damaged components before further use. Never replace any parts with nonidentical ones.
• Standard ultrasonic cleaning is NOT recommended for porous items like corals or gemstones
like pearls, emeralds, and opals. Apply degassing and gentle cleaning for them.
• DO NOT use uids which can damage the stainless steel surface of the tank, such as strong
acid or bases.
• When using aqueous uids, deionized, demineralized, or distilled water is recommended to
avoid harmful impurities.
• DO NOT drop items or place them directly into the tank as this may damage the transducer
before or during use. Always deposit items into the tank gently. For best results, use the
provided mesh basket to hold them.
• To extend the service life, do not operate this device for more than 30 minutes continuously.
• ALWAYS remove all items before emptying the used uid from the tank.
Warning!
Caution!

Operation
1. Remove the lid from the top of the ultrasonic cleaner and fill the tank with the fluid
appropriate for your task (see "Recommended Settings" below), being careful that its level
will not exceed the maximum height mark once your items are added.
2. To avoid damage to the tank during use, place the items to be cleaned into it gently. It is
highly recommended to use the provided mesh basket to avoid direct contact with the tank.
For optimal cleaning effectiveness, do not overlap items. Place the basket in the tank,
ensuring your items are fully submerged while the uid remains below the maximum height
mark. Remove excess uid appropriately if necessary. Replace the lid.
3. Connect the device to a grounded 3-prong outlet using the provided power cord. Do not
use a 3-to-2 prong adapter or ungrounded power strip.
4. Flip the main power switch behind the device to I. The uid’s current temperature should be
shown on the control panel.
5. Press the ▲ or ▼ above “TIME” to set the length of ultrasonic cleaning up to 30 minutes.
To extend the cleaning time, hold the
above “TIME” until “99” is displayed, enabling you
to set the timer to 1–99 minutes.
Continuous use longer than 30 minutes is NOT recommended and will shorten this
device's service life. For best results, use repeated 30 minute sessions paired with 15
minute rest breaks when prolonged cleaning is needed.
When nished with time adjustment, press the
above “TIME” again to activate ultrasonic
cleaning at the uid’s current temperature. The oscillation indicator light should come on
and the remaining time count down in the display area.
6. Press the ▲ or ▼ above “TEMP” to set the working temperature at 0–176°F or 0–80°C and
press the
above “TEMP” to begin heating. The heating indicator light should turn on and
your uid should grow hotter until the set temperature is reached. To end heating, press the
above “TEMP” again.
Be aware that this unit DOES NOT automatically deactivate its heating once the target
temperature is reached. ALWAYS turn off the heating unit manually when cleaning
sensitive objects.
7. The device applies standard intensity for ultrasonic cleaning by default. To toggle to gentle
cleaning, press GENTLE. The gentle cleaning indicator light should come on and the
device will reduce the force of its oscillation. To return to standard intensity, press GENTLE
again.
8. The device works continuously by default. To toggle to periodic degassing, press DEGAS.
The degassing indicator light should come on and the cleaning will begin to alternate 10
seconds of cleaning with 5 seconds of rest to allow air, nitrogen, and other dissolved gases
time to escape. To return to continuous oscillation, press DEGAS again.
9. The device will stop cleaning automatically at the end of its countdown. Press the
above
“TIME” at any point before that to pause or stop work early. Press it again to resume.
(Remember that heating WILL continue until it is separately deactivated.)
10. When nished, ip the main power switch to O and disconnect the device from power.
11. Allow time for the heated uid to cool if necessary. Open the lid, remove the basket from
the tank, and take out your items. Rinse any remaining detergent off their surfaces with
clean water as needed. Hold the device tightly and pour the used fluid into a sink or an
appropriate drainage facility. Rinse away any remaining detergent from the surface of the
tank with clean water if needed.

12. Use a soft cloth to dry the exterior of your items, the tank, and the basket or allow time for
everything to air dry.
Recommended Settings
• Highly Porous Objects: Use a specialized ultrasonic cleaning uid or water with a mild
detergent at temperatures appropriate for the item. Keep degassing continuously active.
• Fragile & Delicate Objects: Use a specialized cleaning fluid at temperatures below
105°F/40°C. Degas for a few seconds at first and then keep gentle cleaning mode
continuously active.
• Lightly Soiled Objects: Use water with a mild detergent at a temperature around
120°F/50°C. Degas for a few seconds at rst and then use standard cleaning.
• Thoroughly Soiled Objects: Use a specialized cleaning fluid at temperatures around
140°F/60°C. Degas for a few seconds at rst and then use standard cleaning.
• Tarnish, Hard Carbon Deposits, Rust, &c: Use a specialized cleaning uid at the highest
temperatures safe for the item. Degas for a few seconds and then soak in the heated
solution for 10 minutes or longer without any oscillation. Use a full 30 minute cleaning cycle
after this presoak. Repeat as needed, allowing 15 minutes for the device to rest between
sessions.
Maintenance
• Turn o and unplug this device prior to any draining, cleaning, maintenance, or repair.
• Replace the cleaning uid between uses.
• Check the parts of this device for any wear or damage after use. Repair or replace any
problematic parts before further use.
• If this device will not be used for an extended period of time, unplug, drain, and fully dry it
before storing it in a cool, dry, and clean place away from direct sunlight and inaccessible to
children.
