SAFETY PRECAUTIONS MUST READ BEFORE USE!
WARNING!
ALWAYS sterilize or disinfect handpieces, inserts, and attachments before use
Use only clean, drinkable, COLD water for lavage
ALWAYS place handpiece in the side bracket after use and NEVER leave on the patient
ALWAYS use only as much power as necessary when scaling and NEVER use high power with
perio tips or the feline urethral catheter
Avoid keeping the insert tip in one place too long
CAUTION!
NEVER operate the scaler without lavage flow
NEVER autoclave the handpieces
NEVER soak the handpieces or inserts
NEVER wind the cord around the scaler handpiece
Place the unit away from heat and with adequate ventilation
Be careful moving the unit due to risk of damage from dropping
NOTE!
ALWAYS turn off water supply and disconnect the water line overnight
PACEMAKERS
Although the use of ultrasound scaling is normally considered safe around pacemakers, never the
less it is advisable to keep the scaler cord as far away as possible from the pacemaker leads. This
advice is applicable to all implanted active devices including cochlear implants, Parkinson’s
stimulators, insulin pumps, etc.

UNIT SET UP
UNPACKING
Verify that all items are accounted for and undamaged:
Veterinary Scaler unit with integral foot pedal
Ultrasonic Scaler hand piece
TFI#3 Scaling Insert
Quick Release Valve water connection
Water Line with Filter installed
Water Supply
Install the ¼” male iron pipe thread coupler body into a source of cold drinkable water with a
pressure of no less than 20 PSI and no more than 50 PSI. If pressure exceeds 50 PSI a regulator
will be required. It is necessary to have a shut off valve in series with the coupler body. The
internal water stop in the coupler body is not meant to act in lieu of a shutoff.
CAUTION! The water itself must conform to CDC standards in order to be free of potential
bacterial contamination and be relatively soft. Excess mineral content will ultimately degrade the
water system in the 2000 Plus unit, requiring repair. All plumbing work must comply with local
building and plumbing codes. It is strongly advised that a licensed plumber be employed to install
the coupling body and shutoff valve into the building water system.
Flush the newly installed quick release coupler via the water hose thoroughly before connecting
to the filter in order to clear out any debris remaining from the plumbing work. Connect the
water supply hose going into the unit to the filter via the Luer Lock fitting. Connect the water line
to the filter via the Luer Lock and then into water supply through the quick disconnect coupling
using the thumb lever release. IMPORTANT! REPLACE THE FILTER EVERY 30 DAYS.
NOTE! Although the flushing instruction given above is meant for one time use on new
installations, it should be repeated if any repair work is done to the building plumbing system or if
building water pressure is lost. Verify that cold water is present after building plumbing work.

OPERATING INSTRUCTIONS
The Veterinary Scaler is a finely engineered instrument, designed to provide years of trouble free
service. The following instructions will help you operate and maintain the unit at optimal
performance.
ELECTRICAL POWER CONNECTION
Plug the electrical cord into the appliance entry on the rear of the 2000 Plus unit. Be sure
that it is fully inserted. Plug the cord into a 120V 60HZ grounded outlet. The
On/Off
selector switch is located on the lower right side of the control panel.
POWER CONTROL KNOB
Adjusting the Power control knob from left to right will vary the power output from low
(left) to high (right). The Specialty area identifies the power setting used by the Feline
Urethral Catheter and Cavitron® SlimlineTM , FSITM, or Modified Periodontal
inserts. Refer to “Setting Power” on page 7 for appropriate power settings
on various scaler inserts.
SCALER HANDPIECE CONNECTION
The handpiece is shipped non-sterile. Disinfect the handpiece before use. See
pages 5 and 6. Insert the plug into the circular jack on the right front of the unit.
Be sure to seat the plug fully. Turn the locking ring clockwise to tighten the plug
securely, but avoid cross-threading, forcing, or over tightening the plastic
threads. Purge the water system prior to use. See page 6. See page 7 for more
detailed information on the scaler inserts.
NOTE: Scaler should not be operated unless there is a Magnetostrictive Insert properly installed
in the handpiece and there is proper water pressure.
ADJUSTING LAVAGE WATER PRESSURE/FLOW
Turning the Water knob in a clockwise direction increases the flow of water
and, conversely, the opposite direction produces a reduction in water flow.
Note this control knob will turn about 2 or 3 turns in either direction. Once
you feel resistance do not turn past that point.
The red Low Pressure light next to the water knob comes on when the water flow/pressure drops
below the safety point. IMPORTANT! Do not operate the Scaler until you have corrected the
condition, and adequate supply water is again available. See pages 5 and 6 for further
information. Lavage is active only in the Scaler mode.

7
USING THE SCALER
Tap at the calculus to start then use slow strokes with light pressure in an apical or oblique
direction with the tip parallel to the tooth surface beginning at the coronal edge of the calculus.
Do not stroke laterally at the calculus with the side of the tip as you would with a curette as this
tends to burnish heavy calculus instead of removing. Note that burnishing can also occur if power
is set too low or the tip is worn down. Allow the lavage cavitation to do the work, do not stroke
too quickly. It is highly recommended to use manual curettage in conjunction with ultrasonic
scaling because manual follow up will reveal any residual calculus and provide tactile feed back of
surface smoothness. The thin perio tips used at low power are excellent for plaque bio-film
removal but need to be used at medium power for hard calculus. For especially heavy calculus
use a general purpose tip. Use only as much POWER as necessary to remove the calculus. Use
normal septic precautions with respect to the water lavage spray due to microbial material lifted
during scaling.
Do not use the tip as a retractor. Because the tip becomes hot due to friction, use as a retractor
has significant risk of burn.
Be sure that the lavage is flowing adequately. The lavage water also serves to cool the
magnetostrictive insert. The scaler insert will fail in less than one minute due to overheating if
there is inadequate water flow.
Ultrasonic magnetostrictive inserts wear at the tip. They will wear out in due course with normal
use and become ineffective. Because of the internal mechanical advantage, a little visible wear
has a relatively large effect on performance. Check the tips for wear regularly, preferably at every
ten autoclaves. The periodontal insert should be checked at every five autoclaves because it is
subject to more rapid wear due to size. See page 7 for more information and alternate inspection
schedule.
STERILIZING AND DISINFECTING
SCALER MAGNETOSTRICTIVE INSERTS
Wipe and clean using warm water prior to autoclave. Use a toothbrush as needed. Do not clean
in an ultrasonic cleaner. Place the insert in an appropriate autoclave bag. Steam autoclave at 1350
C and 215kPa (2750 F and 30 PSI) for a minimum of 12 minutes followed by 20 to 30 minutes
drying time. Do not use dry heat.
SCALER
Clean the Scaler handpiece thoroughly to remove any detritus or saliva. Wipe down with an
appropriate topical disinfectant. Do not allow fluid to enter the handpiece. Shake off fluid and
allow to dry.

8
STERILIZING AND DISINFECTING (CON’T)
The autoclaving parameters given reflect the recommendations of our component vendors.
These recommendations are not intended to supersede routine spore testing in accordance with
your state and local health department regulations, where required. It is highly recommended
that a spore test be done in any case to verify your autoclave at the parameters cited.
CAUTION! Scaler handpiece is NOT autoclavable.
Disinfect these items by wiping off any detritus or fluid and then wiping down with an
appropriate topical disinfectant. NEVER soak these items.
PURGING THE WATER SYSYEM
Purging the water system is done each day after the water is turned on and
each time an insert is changed. It is necessary to clear the water system of
air before operating the Scaler because entrapped air can cause the insert
to overheat and to make a high pitched squealing sound. Proceed by
turning on the water, turning on the unit and without the insert in place.
Hold the handpiece vertically with the insert end up and step on the pedal
allowing water to flow. Continue until the water flow is free of bubbles.
Note the mushroom shaped meniscus on the water as it leaves the handpiece.
With the handpiece still vertical and the system free of air, release the foot
pedal and slowly lower the insert into the handpiece. When the insert is
about 3/8”
(10 mm) from being fully inserted, push it the final distance with a twisting
motion. The twisting motion serves to lubricate and seat the “O” ring water
seal. Be sure that the insert is all the way in (fully seated).
When the system is purged and the insert is oscillating, the resulting lavage
flow forms a fine, fan shaped mist pattern as the water stream is dispersed
by the oscillating tip.
NOTE: Lavage flow from the insert depends on the procedure. The range is from 18 cc/minute to
40 cc/minute. Remember that lavage flow is necessary to cool the insert and the tooth.

9
INSERT WEAR, CARE, and SELECTION
Inserts wear out with normal use. Compare your insert against the full size illustration on page 8
to gauge how much wear has occurred. A monthly check is appropriate for the DE-5 and DE-6,
however the finer DE-6A should be checked bi-weekly.
When the tip reaches back to the blue line, efficiency is reduced by 25%. When the tip reaches
back to the red line efficiency is reduced by 50% and the insert should be discarded. If the tip is
bent or damaged, discard the insert. Note that only 1mm of wear can reduce power by 50% due
to the mechanical advantage inherent within the internal coupling between the magnetostrictive
stack and the tip.
Be careful to avoid damage to the magnetostrictive stack (the metal laminations behind the
plastic portion). If broken laminations are evident, discard the insert.
Do not clean with an ultrasound cleaner. Never soak the insert. Never allow to run dry.
SETTING POWER
The correct power setting is primarily a function of the tip type. Perio tips and the feline urethral
catheter tips require low power. Using “normal” power with the fine tips may easily break them.
Use the following chart as a guide. Always use the lowest power setting possible to accomplish
the desired result.
NOTE: “Thru-flow” types are generally for supra-gingival use while “Focused spray” types are for
periodontal and sub-gingival use. Lavage terminates immediately when the foot pedal is released
with “Thru-flow” types whereas the “Focused-spray” types produce a stream of water for a short
time after the pedal is released in order to give a full flush of loose detritus.

PORTABLE WATER SUPPLY (DE-4)
The optional DE-4 water tank allows the 2000 Plus Scaler Motor Pack Combo to
be used anywhere that 120V 60Hz electrical power is available.
The DE-4 tank is fitted with a hose terminated by the same quick release coupler
normally shipped with the 2000 Plus allowing very rapid change over from fixed
to portable use without tools.
It is imperative for antiseptic reasons to fill the DE-4 tank only with clean,
drinkable, cold water. See page 1. Distilled water is desirable because it has the
additional advantage of being mineral free.
Anti-microbial agents per se added into the water do not harm the DE-4 tank or the 2000 Plus
water system. However, over time and with continual use, deposits will form in the tubing and in
the water system. Depending on concentration, deposits in the 2000 Plus water system could
eventually become severe enough to restrict water flow to the point where the unit will have to
be returned to Delmarva 2000TM for service. The same is true for hard water.
USING THE DE-4
Remove the top of the DE-4 by turning counter-clockwise. Each day fill
with clean, drinkable, COLD water. Do not use hot water. Replace the
top by turning clockwise. Using the handle, pump up the pressure until
the yellow ring is visible. Connect the water line from the 2000 Plus
unit via the quick disconnect. See page 6 for purging the system. NOTE:
Under typical conditions, it is expected that the water in the DE-4 will
eventually reach room temperature. This is normal and the 2000 Plus
should operate as intended.
At the end of each day’s use, release pressure from the tank by pulling out the button on the side
of the DE-4 tank. Uncouple the quick disconnect. Note that the button may be rotated ¼ turn
counterclockwise and will stay open until turned back clockwise.
To insure cleanliness of the DE-4, it is advisable to periodically rinse it out with a suitable anti-
microbial solution. Be sure to drain and rinse thoroughly before use with the 2000 Plus unit.
Drain and refill regularly. Do not allow water to become stale. Be sure to drain the DE-4
completely if storing or transporting in freezing conditions.
