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.
SweepZone Technology® enhances
the ultrasonic activity by automatically
changing frequencies, thus creating a
cleaning grid which literally sweeps
through the tank. A more uniform
cleaning pattern and significantly shorter
cleaning times result when “hot spots”
present in traditional ultrasonics are
eliminated.
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
System. Your machine is part of a complete cleaning process which
is thoroughly 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.

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
Table Top Machines
 Select your desired location for the cleaner. It should be in close
proximity to a sink or waste lines to facilitate ease of draining. A drain
assembly, supplied with the cleaners having drains, 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.
Directions for Attaching Pre-Assembled Drain Hose
for 140, 200 and 210 models
1. Open bag and remove pre-assembled drain hose.
2. Loosen large black nut on the elbow (drain fitting) at end of the
drain hose by turning 2 – 3 complete revolutions. (Be Careful:
Excessive turns will result in the black nut falling off and the elbow
coming apart.)
3. Turn the ultrasonic
machine so the back of
the unit is facing you.
Locate the metal drain
tube coming out of the
machine. Slide the elbow
(drain fitting) over the
metal drain tube until
elbow is almost flush with
back of machine. (Note:
Sliding the elbow will
require some force and it
is recommended to place
one hand on the front of
the machine for stability.)
4. To tighten elbow (drain fitting), turn the black nut counter-clockwise
while holding the elbow in place. (Be careful not to over-tighten the
black nut.)
5. Close drain hose by pressing down on pinch clamp until secure
(approximately 4 “clicks”).
6. Secure end of plastic tubing into clip at top of machine.

10
Attaching the Drain Assembly for 310 and 650 models
 Pick up drain assembly supplied and loosen nut on
elbow.
 Position machine so that you are facing the drain tube.
 Carefully slide the assembly over the drain tube.
 Adjust the position of the drain tube as desired. (Drain right, left or
down.)
 Hand tighten nut. Do not over-tighten. If further
tightening is needed an adjustable or a 1 inch open-ended wrench is
recommended.
Recessed Machines
Installing the Tank in Your Countertop
Your recessed ultrasonic cleaner is designed to be a permanent
installation into a countertop in your office or shop. It is recommended
that the stainless steel mounting rim supplied with the cleaner be
installed between the rim of the tank and the countertop to ensure a
good, watertight seal at the countertop. A cable or cables (depending on
the model) will connect the tank to the generator.
1. Select your desired location for the tank on your countertop. Close
proximity to a sink is desirable for ease of drain connections.
a. Make sure there are no drawers below your selected position on the
countertop and that there are doors which allow easy access to the
drain valve on the tank.
b. If the cable(s) interconnecting the tank and generator can not be
routed behind the countertop, a separate hole will have to be drilled in
the countertop to accommodate them.

2. Included with your recessed cleaner is a stainless steel
mounting rim. Use it as a template and trace the
required cut out on your countertop with a crayon or
china marker.
3. Drill a ½ inch hole anywhere within the section to be
cutout.
4. Using a sabre saw, carefully cut the tank shape out of
the countertop.
5. Clean away saw dust. Position the mounting rim over the
cut out and check fit. Adjust hole if required.
6. Remove rim. Carefully apply a bead of clear silicone (GE
732 or equivalent) ½ inch wide, ⅛ inch high around the
cut out.
7. Position mounting rim over cut out.
8. Carefully apply a bead of silicone ⅜ inch wide, ⅛ inch
high around the inside edge of the mounting rim.
9. Set the tank into the rim. Allow the silicone to squeeze
out. Wipe the excess silicone.
10. Allow the tank to set for at least eight hours without
being disturbed.
11. After the silicone has cured, carefully scrape any
excess silicone, being careful not to scratch the rim or
countertop.
Recessed rim option
Recessed rim installation is similar. For specific details
check instructions supplied with that option.
Connecting the Drain
Protruding through the bottom of the tank assembly on a
recessed machine is a drain valve and associated fittings
and a 36” length of tygon tubing.
Every recessed installation is unique because of different
counter sizes, access to waste lines, etc., and should be
done by a plumber or technician in accordance with local
plumbing codes.
Mounting rim
Bead of silicone about 1/2" (not to scale)

12
If a sink and sink drain are near the location the recessed
cleaner is to be installed, we recommend changing the
sink’s tailpiece to a “dishwasher tailpiece”. Then, using an
appropriate combination of adapters/fittings, the drain
tubing can be connected to the tailpiece. See sketch.
Interconnecting The Tank and Generator
 S150R—Connect the coaxial cable from the tank into
the R.F. connector on the rear of the generator
(Turn Clockwise to lock connector).
 S310R, S360R, S650R—Connect the coaxial cable
from the tank into the R.F. connector on the rear of the
generator (Turn Clockwise to lock connector) and the
thermo probe cable into the 3 pin connector on the rear
of the generator.
 Connect the green/yellow wire from the tank to an
appropriate earth ground such as a cold water supply pipe
using a grounding clamp or similar approved grounding
device.
Do not attempt to connect or disconnect any cables with the
generator plugged in. Connect the generator plug last.

13
Start Up
STEP ACTION
1Select the proper L&R Cleaning Solution.
2Dilute with warm tap water as specified and
fill one half to two-thirds of the tank.
3
Add parts to be cleaned. Use a basket or
other accessory which keeps material off the
bottom of the tank. If necessary, add more
solution to bring the level to about 1 inch
from the top of the tank.
4
Plug the cleaner’s line cord into a grounded
outlet.
5
To activate your machine, simply set your
timer (on mechanical timers turn knob
clockwise) to the number of minutes desired
for cleaning. These self-timing units will
automatically shut themselves off at the end
of the cycle.
For recessed installations with an optional
remote timer… connect the machine’s power
cord to the outlet on the rear of the remote
timer and connect the remote timer’s power
cord to a grounded outlet. Set the machine’s
timer to the “HOLD” position. Then set the
timer on the remote to the number of
minutes desired for cleaning.
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.

14
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
machine. There are five different selectable predefined timer settings (6, 12,
20, 30, 60 minutes). The timer set button (Item 1) is in the center of the time
selection indicator lights (Item 3) just below 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. If
the timer button is pressed again a second time then the 12 minute indi-
cator will light and the unit will then run for 12 minutes and turn off when
done. 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 from 6 to 12 to 30 to 60 and then to Standby (off). The
time indicator light remains lit until the end of the cycle.
Optional Heater Section: The heater section has the heater push button
(Item 4) and a Red indicator light (Item 5). The light is active when the heater
circuit is energized. The heat remains on until the button is pressed again and
the indicator light goes off. If the unit has not had any buttons pressed for 2
hours the heat turns off as a safety precaution. Heat should not be left on unat-
tended. The operator should not rely on this automatic feature to turn the
heat function off automatically - 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.

15
Mechanical Timer
START-UP
1. To start your machine set your timer (item 1) to the pre-set
time (item 2) desired for ultrasonic cleaning. The machine will
automatically shut itself off at the end of the pre-set time.
2. Machines equipped with heat have a separate “On-Off” rocker
switch (item 3) located on the front panel. Pushing this switch
to the “On” position allows pre-heating of cleaning solution
prior to turning on the machine. The rocker switch is lit when
the heater is on and must be pushed to the “Off” position
when the heater is not in use.
3. The heater is designed to maintain the temperature of the
cleaning solution between 125°-150°F (52°– 65C°). When you
operate both the ultrasonics and heat simultaneously with the
tank covered for an extended period of time, the solution tem-
perature will rise above this level. At this point, the thermostat
will automatically shut the heater element off until the solution
drops below maximum heat level. The thermostat will be reac-
tivate as required. During this cycle, the heat indicator light will
remain lit. Because of the intense ultrasonic power dissipated
in the form of heat, the temperature of the solution may once
again rise above 150°F with the ultrasonics operating.
The heat rocker switch must always be turned off
manually. This switch does not turn off automatically.

16
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:
A ring suspended directly into the tank.
Instrument cassettes, held in a cassette rack and placed
directly into the tank.
items in basket*
basket

17
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.
Fill the stainless steel tank
approximately ⅔ full with a
proper L&R solution or carrier
bath.
Fill auxiliary pan or beaker (s)
with designated L&R cleaning
solution(s) to a level just above
the item(s) to be cleaned.
Place auxiliary pan into main
tank, resting it on its handles,
making sure that the bottom of
the auxiliary pan is below the
solution level in the main tank,
add water if necessary. This
insures proper sound wave
transference.
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.
