6 - Maxima Advanced Ultrasonic Cleaner MA210
3. Place the removable cleaning chamber across the top of the tank. The bottom of the chamber
should be in contact with water for about 1/2” or 10 mm in depth. Ultrasound will penetrate the
removable chamber to clean the items inside.
4. Close the lid. Turn on the power switch. Turn the timer dial to select the cleaning time. Choose 5
to 10 minutes and push in the dial to start ultrasound.”
MACHINE CLEANING AND MAINTENANCE
• Do not run the unit for extended time or continuously. The unit is designed with overheat protec-
tion. If the unit has been running for 30 minutes, it is recommended to stop the unit for about 10
minutes to prolong the life of the unit.
• Do not keep water in the cleaning tank for a long time. After cleaning is completed, open the
drainage valve to drain the dirty water. Clean and wipe the tank dry.
• Keep a strainer over the drain inlet to prevent small instruments such as burs and files or large
debris from clogging the drain valve.
• If condensation water forms on the lid, shake it off or wipe it before placing the lid on the lid hold-
er to avoid water dripping down from the lid.
• Do not spread disinfectant over the housing or the tank. Use clean water to wipe the housing.
Use a paper towel to dry up the tank and the housing. Use a disinfectant wipe that doesn’t dam-
age aluminum and ABS plastic to wipe the tank and the housing if needed. Many disinfectants
and bleach products contain sodium hypochlorite with strong oxidation. They will darken the
aluminum housing.
• Do not use corrosive solutions such as liquid bleaches in the stainless steel tank.
• Do not use corrosive solutions such as paint thinner or acetone as it will corrode plastic housing.
Do not use flammable solutions.
• Do not use osmosis water or highly purified water as they may corrode metals aggressively. Avoid
spilling water over the control panel or inside the housing.
• Keep the unit in a dry, cool and ventilated area.
• Do not expose the unit under direct sunshine for a long time.
• Keep the original packing material in case of sending it for repair service. If it is no longer avail-
able, use enough cushioning equivalent to minimum 2” of Styrofoam all around the unit inside
the shipping carton to avoid damages to fragile transducers.
Foil Test
Ultrasonic cleaners should be tested periodically or as needed for cleaning performance and to verify
that the transducers are working properly. The test results should be documented.
Procedure:
Remove the lid, basket, containers, and anything else in the tank.
1. Clean the tank thoroughly.
2. Fill the tank with water to halfway between the MIN and the MAX lines.
3. Take 2 pieces of autoclave tape and run them from left to right over the top rim of the tank. One
tape goes over the centers of 2 round cycles on the bottom of the tank. One tape goes over the
third cycle on the bottom of the tank. The transducers that generate ultrasound are mounted
underneath each circle.
4. Obtain a piece of standard household aluminum foil and cut 3 pieces 2cm (3/4”) wide and 13 cm
(5”) long. Fold each piece to L shape along the length. Do not use heavy duty foil.
5. Stick one foil above the center of each circle, sticking the end to the underside of the tape. Keep
the foils vertically into the water with the bottom edge approximately 2-3 cm (1”) above the bot-
tom of the tank.
6. Turn on the ultrasound under the normal cleaning mode and run for 1 minute. Stop it once the
time has been reached.
7. Remove the foils and inspect. The foils should be perforated or knocked off along the 3 edges.
8. If any one of the foils has no obvious perforations, the transducer near that foil may not be working
properly. Call Henry Schein® Handpiece & Small Equipment Solutions if this happens.
9. Flush out the loose foil particles from the tank and clean it thoroughly.
