AC-SERIES ULTRASONIC CLEANER
USER MANUAL

INTRODUCTION
Ultrasonic cleaning is based on the cavitation effect
caused by high frequency ultrasonic wave vibration
signal in the fluid. Microscopic bubbles are formed,
and they implode violently causing the cavitation
which create an intense scrubbing action on the
small enough to penetrate microscopic crevices,cleaning
them thoroughly and consistently.Ultrasonic cleaning is
extremely effective at removing dirt and grime which
would normally require tedious manual cleaning by hand.
It has been used to clean a wide variety of instruments and
mechanical parts such as carburetors,returning them
to almost “like new” condition without damage to delicate parts.
surface of the item being cleaned. The bubbles are
PREPARATION:
1、Carefully unpack the cleaner and remove all traces of packing materials
from it. Visually inspect the cleaner for any parts that may have become loose
or damaged during transit.
Contents:
a: Main machine b: Lid c: Power cord
d: Outlet filter e: User manual f: Mesh basket
2、Place the cleaner on a flat, clean surface where the cooling fans will receive
adequate ventilation and ensure all controls are set to off. Also ensure the
drain tap is in the closed position.
3、 Ensure the power lead is securely plugged into the cleaner and that no part
part of the lead is likely to come into contact with moisture.
4、Carefully fill at least 1/2 of the tank with a solvent solution. For demanding
cleaning we recommend a small amount of washing up liquid, this will help
increase the cleaning performance. The cleaner is now ready for use.

Attention
While the machine is working normally, ultrasonic and tank syntony
gives a well-proportioned sound, and no shudder on the surface of the
water, yet there is spray made by the tiny bubbles. If there are discontinuous
surges, please add or release a little of washing solution in the tank,
stopping the surges is better for the objects cleaning.
Please read the following very carefully as failure to comply may
invalidate your guarantee.
1) DO NOT run the cleaner continuously for more than 30 minutes at a time, as
doing so can damage the internal components.
2) DO NOT operate the unit without fluid in the tank. Always ensure the fluid is no
higher than the max mark, Always ensure there is a minimum depth of 7cm.
3) DO NOT drop any item into the tank as this may cause damage to the
transducer. Always place the items gently into the tank and use the basket.
4) The more items that you place in your cleaning bath the less efficient it
will clean.It is not advised to overlap items. Always allow plenty of clear
space between the items.
5) Do keep the lid on during use. This will prevent splashes and reduce
evaporation of the fluid.

SAFETY PRECAUTIONS
Keep it away from children!
This device is not intended to use by individuals with restricted physical
sensory or metal capacities or those with lack of experience or knowledge,
include children, unless they are supervised by an individual who is responsible
for their safety or have received training in operating the device.

6) Never immerse the machine or power cord in water or other liquid.
7) DO NOT touch the power plug with wet hands, especially when inserting
or removing the plug.
8)DO NOT touch the unit if the machine has fallen into water during operation.
Remove the power plug from the socket first.
9) DO NOT disassemble the machine, except by professionals.
10) UNPLUG the power source while filling or emptying the tank.
11) DO NOT spray water or liquid over the device and the control panel
12) DO NOT operate the cleaner without proper grounding.
13) DO NOT place the device on a soft surface, where the vents could be blocked.
14)Upon completion of the cleaning cycle, turn the heater knob off and isolate
the machine from the electrical supply.
15)Take care when adding or removing items from the cleaning tank as the
fluid is likely to be hot and displaced fluid can damage the internal components.
Any displaced fluid must be dried up immediately.
16)In the event of failure/emergency, disconnect the mains supply by removing
the plug from the mains socket.

DIFFERENT WAYS OF CLEANING
GENNRAL CLEANING—use only tap water. Use warm temperature about 50 .℃
ENHANCED CLEANING—add few drops of standard washing up liquid liquid soap, ，
or detergent into water, other non-acidic cleaning agents can also be used.
EXTENSIVE CLEANING—removing tarnish, carbon & rust from non-plated metals, it is
recommended to use specialist cleaning solution in associated using ultrasonic cleaner.
When
finished
use
1.When the cleaning is completed, turn off timer and heating.
Then turn off the power switch in back of the machine
2. Unplug the power cord, open the lid and retrieve the basket
and the items.
3. Empty the tank and clean both the outside and inside of
the machine with clean and dry cloth for next use.
4.Keep the drainage valve closed.(for machines above 6L).
WARNING : Strong acid or alkaline cleaning solution will cause
corrosion, rust and even puncture of tank or machine body. To
overcome this problem, dilute to mild PH solution or request for
tank made of specific grade of stainless steel like SUS304.
