Sper Scientific 100005 Ultrasonic Cleaner - Mini - Manual (Page 2)

Operating Procedures
1. Plug the unit into a grounded 100~120V outlet,
preferably with a ground fault interrupt (GFI) to prevent
fire, injury or electrocution.
2. Open the cover to wipe the tank with a clean cloth.
3. Dropping objects into the tank can damage the circuity,
so gently place the object to be cleaned into the tank.
Note: If a sharp tool touches another metal object
during the cleaning cycle, the ultrasonic action can
dull the edge. Use plastic baskets so that such tools
don't touch the metal.
4. Fill the tank with enough water to cover the item but
not exceed the MAX line. The unit can be damaged if it
is operated without sufficient water. If desired, a few
drops of mild phosphate-free detergent may be added
to the water. The use of disenfectants is not
recommended as they may produce harmful vapors. If
you use a dipping basket, the unit's stainless steel tub
must also be filled with water.
5. Press the "ON" button to start the cleaning cycle. The
unit will automatically shut off after 3 minutes. Never
leave the unit unattended during operation. In some
cases, pre-soaking or repeated cleaning cycles may be
required. After extended operation, if the water
becomes too hot (over 158°F / 70°C) replace with cool
water before continuing.
6. To stop the unit during a cleaning cycle, press the
"OFF” button.
7. When you are finished, unplug the unit and clean the
exterior, buttons and electrical cord with a damp cloth.
