water-based solutions.
•Do not ever use mineral acids. These could damage the tank.
•Do not touch the stainless steel tank or cleaning solution -- they may
be hot.
•Do not allow fluid temperature to exceed 70ºC (160ºF).
•Do not place your fingers or hands into the tank while the cleaner is
operating. Doing so may cause discomfort and possible skin irritation.
Avoid contact with solutions and provide adequate ventilation.
•Do not use solutions containing chlorine bleach.

2 Safety Precautions
To prevent damage to the cleaner:
•Do change your solution regularly.
•Do not cover vents on the cover.
•Do not operate the cleaner dry.
•Do not place parts or containers directly on the bottom of the cleaning
tank; use a tray or wire to suspend items. Failure to comply may
cause transducer damage and will void your warranty.
•Do not allow the solution to drop more than 3/8 inch below the
operating level line with heat or ultrasonics on. Failure to comply may
cause transducer and/or heater damage and will void your warranty.

3 Introduction
Introduction
Ultrasonic Cleaners
This line of ultrasonic cleaners include five models with sizes ranging
from 1/2 gallons, 3/4 gallons, 1-1/2 gallons, 2-1/2 gallons and 5-1/2
gallons. Each model is constructed using durable industrial style 40kHz
transducers. These provide increased cleaning power along with built in
sweep frequency to ensure uniform cleaning activity throughout the bath.
The 1/2 and 3/4 gallon models have a molded dip in their rims to facilitate
emptying of solution from the tank. The three larger sizes have built in
drains and are supplied with tank drain kits. Each model can be
purchased in three different configurations -- with a Mechanical Timer
(MT), with a Mechanical Timer plus Heat (MTH) and with Digital Control,
plus Heat and Timer (DTH).
When you first fill your unit, or refill it with fresh solution, use warm water
for the solution. Turn on the heater (press the HEAT switch, if available),
turn on the ultrasonics (press SONICS or rotate the Timer knob), add the
cover and the solution will heat quickly to temperature.

4 Introduction
Accessories For Your Cleaner
Accessories include regular and beaker positioning covers, solid and
perforated insert trays, mesh baskets and beakers.
Unpacking Your Cleaner
Please check your cleaner and its carton carefully for any external or
internal damage. If you find damage, contact your shipping carrier
immediately, before contacting your distributor. Please retain your
packaging for future use.
Installing Your Cleaner

6 Introduction
How Ultrasonics Cleaning Works
Ultrasonic sound is sound transmitted at frequencies generally beyond
the range of human hearing. In your ultrasonic cleaner, ultrasonic sound
(sonics) is used for cleaning materials and parts. This is how it works:
•As the sound waves from the
transducer radiate through the
solution in the tank, they cause
alternating high and low pressures
in the solution.
•During the low pressure stage,
millions of microscopic bubbles
form and grow. This process is
called CAVITATION, meaning
“formation of cavities”.
•During the high pressure stage,
the bubbles collapse, or “implode”
releasing enormous amounts of
energy. These implosions act like
an army of tiny scrub brushes.
They work in all directions, attack-
ing every surface and invading all
recesses and openings.

unit, rinse the tank thoroughly and refill with new solution.
WARNING
Do not immerse the cleaner in water.
Unplug the cleaner from the power source.

15 Operating Your Cleaner
1-1/2, 2-1/2 and 5-1/2 gallon models include a drain and valve kit.
Step Action
1Place the cleaner to allow easy reach of the drain tube into a waste disposal
unit.
2Remove the thread protecting cap from the end of the cleaner’s drain pipe.
This will expose the white teflon sealing tape on the drain pipe’s threads.
3Hand tighten the drain valve onto the drain pipe over the white teflon sealing
tape. Finish tightening the valve in place using on adjustable or a 21mm
wrench. Tighten the valve no more than one full turn when using the wrench
until the handle is on top.
CAUTION: Over tightening of the valve can cause damage to the ultrasonic
tank. Always use teflon sealing tape or a sealing paste designed for use with
stainless steel if retightening or refitting of the drain valve is required.
4Hand tighten the hose adaptor into the end of the drain valve. Slide the drain
tube over the barbed hose adaptor end.
5Close the drain valve by turning the handle perpendicular to the valve body
and the cleaner is ready to fill with solution. To open the valve and drain the
cleaner, turn the handle so that it is in line with the valve body.

16 Operating Your Cleaner
Optimizing Your Cleaner
Tanks
Cleaning - check the tank for contamination whenever you change
solution. If necessary, remove contaminants with a nonabrasive cloth
and water.
Emptying - always unplug the cleaner before emptying the tank. Empty
the solution into a waste disposal unit.
Filling - always unplug the line cord before filling the tank. Fill the
cleaner to the operating level (one inch from the top with beaker/tray in
place), using warm tap water.
Low solution level - will cause the cleaner to fail. When you remove
heavy or bulky loads from the cleaner, the solution level may drop below
the operating level. If so, be sure to replace lost solution and degas, if
necessary, depending on the amount used.
Overload - do not rest any items on the tank bottom. Weight on the tank
bottom dampens sound energy and will cause damage to the transducer.
Instead, use a tray and/or beaker positioning cover to support all items.
Allow at least one inch between the tank bottom and the beaker or
receptacle for adequate cavitation.
Covers - allow the cleaner to heat up faster, to a higher temperature, and
avoid excessive liquid evaporation. However, obstructing the cover vents
will cause the cleaner to overheat.
Temperature
Heater - the heater may cause some discoloration of the tank wall. This
is normal and will not affect the performance of the unit.
Solution - the fastest method to heat your cleaner is to fill with warm
solution, use heat, ultrasonics (which also adds heat), and a cover.
Approximate stabilization temperatures with ultrasonics and heat running
continuously:
MTH/DTH cleaner without a cover 50º
MTH/DTH cleaner with a cover 62º continued...

17 Operating Your Cleaner
Over temperature protection (DTH only) - the cleaner will shut down at
75ºC and the LED display will blink “75”. Turn the cleaner off and allow it
to cool down. For a faster cooldown, replace some of the warm solution
with cold solution.
Solution
Solution activity - the amount of visible activity is not necessarily related
to optimum cavitation for cleaning.
Degassing - fresh solutions contain many dissolved gases (usually air),
which reduce effective ultrasonic action. Although solutions will naturally
degas over time, using Degas mode speeds up the degassing process.
Solutions that have been sitting unused for 24 hours or longer have
reabsorbed some gases.
Heat - increases the chemical activity of cleaning solutions.
Surface tension - can be reduced by adding solution to the bath.
Reduced surface tension will increase cavitation intensity and enhance
cleaning.
Solvents - never use solvents. Vapors of flammable solutions will collect
under the cleaner, where ignition is possible from electrical components.
Renewal - replace cleaning solutions often to increase ultrasonic
cleaning activity. Solutions, as with most chemicals, will become
depleted over time. Solutions can become contaminated with suspended
soil particles which coat the tank bottom, inhibiting ultrasonic activity.
