INTRODUCTION
Use tap water. Chemical solutions are unnecessary in most cases.
Principles of ultrasonic cleaning:
Millions of tiny air bubbles are generated inside the liquid by high frequency vibration.
The air bubbles bust inside the liquid and shake off the debris to achieve the cleaning effect.
Purified water or distilled water has the same cleaning effect as regular tap water
for ultrasonic cleaning. Therefore using tap water is sufficient.
When cleaning silver or copper items where oxidation has darkened the items,
special solutions need to be added to the wa ter to remove the oxidation.

SAFETY PRECAUTIONS
Keep it away from children!
This device is not intended for use by individuals with restricted physical,
sensory or metal capacities or those with a lack of experience and / or
knowledge, including children, unless they are supervised by an individual who
is responsible for their safety or have received training in operating the device.
Please store the ultrasonic cleaner where it is not reachable by children.
Danger to children! Danger for death through suffocation! Keep the packaging material
away from children.
To prevent life-threatening electrical shock, please
observe the following:

The installation of an earth leakage circuit break e r wit h a rate d trip pi ng cu rr en t of no
more than 30 mA provides further protection against an electrical shock. The installation
should only be carried out by a trained el ec trici an.
The device may come with a polarized plug (one blade is wider than the other) for certain
countries. As a safety feature, this plug will fit into a polarized outlet only one way.
If the plug does not fit fully in an outlet, reverse the plug. If it still does not fit, contact a
qualified electrician.

SAFETY PRECAUTIONS
To prevent fire hazards, please observe the following:
Never block the vents on the device. Keep the vents free from lint, hair and ot her
materials.
Do not place the device on a soft surface, such as a bed or a couc h, wh er e th e ven ts
could be blocked.
Observe the other warnings in the previous section.
Other observations:
Do not operate the pro duct without filling the tank with water. Running dry will damag e
the unit.
Do not plug in the power cord before adding water to the tank. Do not fill the tank above
the Max line to avoid overspill.
Do not use solution containing abrasive substances or strong corrosive chemical solution
not recommended by the manufa ctu r e r or the su ppl ie r.
Place the device on a dry and flat surface for operation.
When the device is subjected to severe elec tr o mag ne tic in t erf er en ce, it m ay m alfunction,
stop operating or lose co ntrol functions. If this happens, unplug the power cord then
reinsert it to restart the device.
Items Not Suitable For Ultrasonic Cleaning
Soft Jewelry:
Pearls, emerald, ivory, coral, agate,
sea turtle shells, etc
Welded, Plated and Glued Items:
Welded or plated metal items, glued
items
Watches:
Except diver's watches with depth
rating over 50 m (150 ft) .
Others:
Glass, ceramic, camera filters with
preexisting cracks.
These items are not hard, so scratches may occur
during cleaning.
Ultrasonic cleaning may increase the gaps inside
the welded joints, plated coating or glued i te m s
and may cause separation.
Because the strong penetration capability of the
ultrasonic wav es, water may get into the watches
if they are not truly waterproof. Use the watch
stand we supply as a precaution.
Ultrasonic cleaning may increase the cracks
pre-existed in the coating on the glasses, ceramic,
and glass. If the items have no pre-existing cracks,
then it is okay.

APPLICATIONS
Jewelry Store s , Jewelry Makers:
Jewelry stores can use ultrasonic cleaners to expand services.
Jewelry such as necklaces, diamond rings, rings, earrings can
be cleaned with tap water to recover the shine.
Jewelry makers can use ultrasonic cleaners to remo v e debris or
abrasive powder from work-in-process items
addition to debris. Turning on the heater will raise the water
Jewelry made with investment casting often has wax layer in
temperature, melt the wax and improve the cleaning.
Optical Stores and Labs:
Optical stores can use ultrasonic cleaners to provide valuable
services. Use ultrasonic cleaner and tap water to remove the
debris between the rim and the lenses so the eyewear gets
professional cleaning and care.
Biology / Chemical Laboratories:
Labs can use ultrasonic cleaners to clean test tubes, glass or
metal containers to remove residual chemicals and materials
that can affect the accuracy of the lab tests.
Dental Clinics:
Dental clinics can use ultrasonic cleaners to clean dental
instruments, to remove blood and small particles left on the
instruments before disinfection.
Silverware and silver, copper, or brass decorations: Debris in the grooves and patterns are difficult to
remove by regular cleaning methods. Greasy stains can be removed by ultrasonic

Homes:
Children and baby items: Debris left in small holes and
crevices are difficult to clean by regular means. Bacteria and

Shooting Clubs
To reuse brass cartridges: Adding special acid-based solution
can make fired brass useable and like new again.
Gun cleaning and care: Cleaning guns after shooting is time
consuming. Adding special solution in the water and using
ultrasonic cleaners can complete the cleaning better, quicker
and easier than traditional methods.
Mobile Phone and Electronics Service Shops
PCB renewal: Non-operational electronics, after falling into
water, or non-operational key pads can be cleaned with
ultrasonic cleaners and pure alcohol to recover the functions.
Watch Service Shops
Precision parts cleaning: Put small parts in a beaker made of
stainless steel or glass filled with lubricant oil, then p lace the
beaker inside the cleaning tank and add water. Ultrasonic
waves will penetrate the beaker and act on the parts to make
them clean
Printing Shops
Unblocking dried printer heads or ink cartridges:
Large printers and inkjet printers often have dried printer
heads or ink cartridges ports. Replacing them with new ones
is very costly. Adding acetone or special cleaning solution and
using an ultrasonic cleaner with a couple of minutes of
cleaning will remove the blockage and make them usable again.
Avoid acetone from contacting the plastic housing to prevent
corrosion. Use Indirect Cleaning explained later and a glass or
metal container for acetone.
Automotive Shops
To clean precision parts: Add 50 ml (3 tablespoons) of
dishwashing liquid in the water, turn the heater on to clean
precision parts such as valves, injectors, gears and bearings.
Ultrasonic cleaners clean debris in tiny holes and crevices
effectively, saving time and effort compared to traditional
soaking and brushing methods.

Degas
When cleaning heavily soiled or greasy items, silver, copper or brass items, chemical solutions
need to be added into the water. The solution may form many small droplets and take a long
time to dissolve in the water. Newly added water may generate many air bubbles on the tank
walls. These will reduce the cleaning effect in the beginning phase of ultrasonic cleaning.
Turning on the degas function will dissipate the droplets and the air bubbles, usually in 90
seconds, and improve cleaning efficiency.
