Safety Precautions and Warnings
Before using your Ultrasonic Cleaner, please read and thoroughly understand these
safety precautions. Failure to comply with these warnings and safety precautions may
result in serious personal injury or property damage.
To avoid electrical shock:
 Unplug your machine from the power source before filling or emptying the
tank.
 Keep the area around the ultrasonic cleaning machine clean and dry.
 Do not operate in wet area.
 Ensure that the ultrasonic cleaning machine is properly grounded. Do not
remove the grounding prong on the line cord plug.
 Do not immerse your ultrasonic cleaning machine in water.
 Do not disassemble your ultrasonic cleaning machine–hazardous voltages
inside the tank are dangerous.
 Warning: Unplug the machine before moving it.
 Warning: Do not ever use alcohol, gasoline or flammable solutions. Doing
so could cause a fire or explosion.
 Warning: Do not immerse the ultrasonic cleaning machine in water or any
other liquid. To maintain the tank unplug, rinse and wipe dry.
CAUTIONS:
 Do not use acids or bleach. These materials can damage the ultrasonic
cleaning tank.
 Use only L&R solutions for best results. CHANGE THE ULTRASONIC
CLEANING SOLUTION DAILY, OR AS NEEDED.
 Do not allow the solution to drop below the operating level of the tank while
the ultrasonic cleaning machine is in operation.
 Never run the ultrasonic cleaning machine at solution temperatures over
160˚F, 71˚C.
 Do not place parts or containers directly on the bottom of the ultrasonic
cleaning tank.
 When using beakers or an auxiliary pan, enough solution must be in the
tank to act as a coupling agent. The beakers should be suspended below
the solution level, but above the bottom of the tank.
 Do not leave the instruments in the ultrasonic cleaning machine overnight;
this may cause corrosion (to the instruments). All instruments must be
rinsed and dried before using.
 Avoid operating the ultrasonic cleaning machine in extremely dusty areas.
 Keep the ventilating louvers clean and free of obstructions.
 Do not disassemble your machine. Contact your dealer or the factory.
 Do not use Plastic Solvents or strong chemicals on surface. Take care not
to spill solution on plastic.
FAILURE TO COMPLY WITH THESE WARNINGS AND PRECAUTIONS
WILL VOID YOUR WARRANTY.

Sound waves are carried through the solution in
the tank and create a unique vibrational pattern
causing alternating high and low pressures in
the liquid.
During the low pressure stage, millions of tiny
bubbles form. This process is called
CAVTATION, meaning the formation of cavities.
During the high pressure stage, the bubbles
collapse or implode, releasing enormous
amounts of energy. Working in all directions,
the bubbles attack every surface and invade all
recesses and crevices, pulling debris off the
object being cleaned.
Equally important to efficient cleaning is selecting a proper solution for the
cleaning task. See page 18 of this manual for cleaning applications and
solutions.
Congratulations on your purchase of an L&R Ultrasonic Cleaning Sys-
tem. Your machine is part of a complete cleaning process which is thor-
oughly described in this owner/operator manual.
What is Ultrasonic Cleaning?
Ultrasonic cleaning is created by sound waves that are transmitted at
frequencies beyond the range of human hearing. A generator
located within your system develops the high frequency power which
causes a transducer to radiate and produce the sound waves.

ENVIRONMENTAL:
 Allow 2” behind unit for air flow.
 Unit to be located in a dry location, 0-35° C, RH 96% Non-
Condensing non-corrosive atmosphere below 2000 M altitude.
Unpack, Set-Up and Start-Up
Unpack
 Remove your ultrasonic cleaner from its shipping container
and inspect it for any possible damage which may have
occurred during shipping. (Claims for shipping damage
should be made immediately against the carrier.)
 Check the serial number of your machine with the serial
number on the shipping carton. If they are not the same,
contact your dealer or the factory.
 Complete the warranty card and mail it to L&R Mfg. Co.
or visit www.LRultrasonics.com to register.
Set-Up
 Select your desired location for the cleaner. It should be in
close proximity to a sink or waste lines to facilitate ease of
draining. The supplied drain assembly, will allow you to
place the unit on either side of the sink or to connect it
directly into a waste line. Provide at least two inches all
around the machine to allow for adequate cooling.
Drain assembly: Place drain
tube over valve exit. Use
pinch clamp to secure.
Drain Operation: The Drain
valve is open when the valve
lever is horizontal.

Place parts to be cleaned in the basket or
other accessory. If necessary, add more
solution to bring the level to about 3/4 inch
below bottom edge of plastic.
4 Plug the cleaner’s line cord into a grounded
outlet.
5
To activate your machine, simply set your
timer to the number of minutes desired for
cleaning. These self-timing units will
automatically shut themselves off at the end
of the cycle.
1 Select the proper L&R Cleaning Solution.
STEP ACTION
2 Dilute with warm tap water as specified and
fill one half to two-thirds of the tank.
NOTE: If this is the first time you are running the cleaner or you
have changed the cleaning solution, you must degas the
solution. Fresh solutions contain many dissolved gasses which
reduce effective ultrasonic action. Although solutions will
naturally degas over time, operating the machine for five to ten
minutes before using it to clean will accelerate the degas
process.
FEATURES:
EFFICA Cover Operation: Close the cover prior to the start of a
cleaning cycle to use the latch option. The cover can be totally
removed or opened and allowed to rest in the open position.
Locking Cover: When the Ultrasonic Cleaner is in use, the cover
automatically locks. Therefore, you are unable to open the cover
during the Ultrasonic Cleaning Cycle. To open the cover, you must
stop the Ultrasonic Cleaning Cycle. The cover automatically unlocks
once the cycle is complete.

8
Digital Timer
The L&R Digital timer controls the operation of the Ultrasonic cleaning machine
and its options. There are three sections of control; Main Power, Timer, Heat.
The Main power on/off switch: Located on the rear panel of the machine near
the line cord and fuse holder. This switch controls the main power to the unit.
When this switch is in the on position it is illuminated and the yellow standby
light, on the front panel, is lit (item 2).
Timer Section: The timer section controls the Ultrasonic operation of the ma-
chine. There are five different timer settings (6, 12, 20, 30, 60 minutes). The
timer set button (1) is in the center of the control panel just above the yellow
standby indicator light (Item 2).
Pressing the timer button once, when the unit is in standby mode will
start the ultrasonic cleaner and select an operating time of 6 minutes.
Pressing the button again increases the time. If the timer button is
pressed while the machine is operating the next time interval is selected
and the machine will continue to operate until the end of this preset time.
Pressing the timer button will increment the time interval and then to on/
off (off).
Optional Heater: Pressing the heat button will turn the heat on, pressing again
will turn it off. The heat light is on when the heat is on. A thermostat regulates
the temperature (to 140°F.) while the heat is on.
If the unit has not had any buttons pressed for 1 hour the heat turns off as a
safety precaution. Heat should not be left on unattended. The operator
should not rely on this automatic feature to turn the heat function off automati-
cally - this feature is for safety only.
The main power switch is intended to be turned off when the machine is not
in use. None of the digital timer functions will work if the main power switch is
in the off position.
1) Timer on/off
2) Standby light
3) Preset timer light
4) Heat on/off
5) Heat on light

Cleaning Methods
Direct Method
In this method, the part(s) to be cleaned are placed in your
accessory basket. The basket is then placed directly into the
main tank already containing the proper L&R cleaning
solution.
Cleaning times may vary depending on the amount and types
of contamination on the items. We suggest that a 3-5 minute
cycle be initiated and more time added if necessary.
Other applications of direct cleaning are pictured below:
Bur tray suspended directly into the tank.
Instrument cassettes, held in a cassette rack and placed
directly into the tank.
Indirect Method
When a cleaning application necessitates a series of different
solutions, or when a specialized solution which is not to be placed
directly into the tank is to be used, the following procedure is
recommended.
BASKET
ITEMS IN BASKET

10
Fill the stainless steel tank
approximately ⅔full with a
proper L&R solution or carrier
bath.
If a beaker or beakers are used,
place the beaker in an L&R
positioning cover using the
beaker band to adjust the depth
of the suspension so that the
beaker bottom is slightly below
the surface of the solution in the
main tank, but off the bottom.

Foil Test
An aluminum foil test is a method to evaluate the general
cleaning intensity and soundwave coverage throughout the
tank. Perform this test as follows:
 Obtain any regular grade (not heavy duty) aluminum foil
sold in a supermarket (less than 0.001 in. thick). Cut a
piece large enough to cover ½ to ¾ of your tank bottom.
 Fill the tank with room temperature water, then add L&R
general purpose cleaner, diluted as specified.
 Run the machine for 10 minutes without a basket and
with heat off, to de-gas the solution.
 With the machine running lower the foil vertically into the
center of the tank.
 Continue to hold the foil and let the machine run for one
minute.
 Turn the machine off and remove the foil.
 Examine your piece of foil. There should be a peening
effect and/or some perforations on the foil. The location
and size of those peening or perforation patterns
indicate the cleaning intensity and uniformity of the
ultrasonic sound waves in the tank.
