INDICATION FOR USE
The MediLectric System is intended to convert pneumatic output from a dental treatment
center into electrical energy in order to drive an electric micromotor that operates electrical-
ly-driven dental handpieces. This system is designed for use by a trained professional in the field
of general dentistry.
ELECTRICAL SAFETY INFORMATION
• Do not handle the power cord with wet hands to prevent an electric shock.
• Do not expose the device to water to prevent an electric shock.
• Do not use the device in a place where flammable materials are found due to risk of explosion.
• No part of the control unit shall be repaired by the user. Do not disassemble the device.
• Place the device on a stable location. Do not drop the device or exert an external force that
may damage the device.
• Do not use a mobile phone or wireless RF communication device close by as such adjacent
use may adversely influence this electrical device.
• This product shall be used only under the rated power specified. Power outside the rate
indicated may damage unit
• Do not use device with a handpiece that does not meet the standard requirements.
• If motor begins to run rough, discontinue use and send in for request to the supplier.
• Check if the speed is set within the acceptable speed range prior to using the speed
control button on the control panel.
• Use only the adapter that is provided by the manufacturer for this device.
• Do not disassemble or tamper with micromotor or control unit as it may damage the device.
• Micromotor generated greater power and torque than traditional air turbines of air motors.
Therefore, handpiece that equipped with micromotor with poorly serviced, damaged or
used improperly can overheat which can cause serious burn injuries to the patients.
• The following guide lines should be followed to ensure the safe operation of electric
handpieces:
• Follow maintenance instruction of handpiece manufacturer.
• Examine the handpiece for damage before each use
• Never apply pressure on the chuck button while handpiece is in operation or use handpiece
as a cheek or tongue re-tractor.

CLEANING & MAINTENANCE
Manual cleaning
NOTE:
• The Micromotor is provided Non-Sterile
• Clean and disinfect the micromotor and tubing before first use and after each patient
• Sterilize the motor after manual cleaning and disinfection.
• Routinely monitor dental unit water quality to ensure microbial counts are below the
levels for drinking water recommended by your local agency. The U.S. Centers for Disease
Control and Prevention (CDC) recommends a level of <500 CFU/ml of heterotrophic water
bacteria.
• After each patient use, disinfect the tubing waterlines include the handpiece and micro-
motor waterlines by flushing with cleaning water to prevent cross-contamination according
to handpiece waterlines disinfection procedure of main dental unit.
Manual internal cleaning for micromotor and motor tubing:
1. Internal cleaning waterlines , the Medilectric System must be conducted through the
main dental unit by connecting to standard 4 hole handpiece connector and follow the
instruction for handpiece and hose waterlines disinfection of the main dental unit.
(using the same procedure to disinfect waterlines of high speed handpieces on main dental
unit)
+ It is recommend to use Waterline Maintenance Tablets for main dental unit, it is the simple
way to maintaining clean dental unit waterlines.
2. Do not remove attached handpiece and the micromotor from the connecting cable during
internal waterlines cleaning and disinfection procedure.
3. Hold the handpiece with micromotor over the cuspidor or over a watertight container on main
dental unit with sufficient capacity and press the purging key on the main dental unit. Setting
time to clean and disinfect the waterlines base on manual instruction of main dental unit.
(Fig.9)
Fig. 9

Manual external cleaning for micromotor and motor tubing:
Recommendation for external cleaning accessories:
• Clean cotton cloth
• Soft brush-Nylon Bristles
• Alcohol 70% Isopropyl
• Protective glove uses during cleaning procedure.
1. For control box, micro motor cable / tubing (non removable) can be disinfected by wiping off
using soft cotton cloth with isopropyl alcohol.
2. For the micromotor, Disconnect the motor from the motor cable / tubing by turning motor
back nut counter- clockwise and gently pull the motor out. (Fig.10)
Fig. 10
• Use air spray to purge the waterline & remove excessive moisture from the micromotor. (Fig. 11)
• Use soft brush with isopropyl alcohol to clean exterior surface then wipe off with soft cotton
cloth.
• Visual inspection the cleanness of the micromotor prior to sterilization cycle.
Fig. 11
Fig. 12
STERILIZATION:
• Micro motor must be sterilized before first use and between each patient use by moist heat
accordance with ISO 17665-1 in a steam sterilizer (Autoclave)
• After manual cleaning(internal & external cleaning), follow the instruction below to autoclave
the micromotor:
1. Autoclave using Air Removal Steam type Sterilizer (pre-vacuum)
• Insert the motor into sterilization bag and load into autoclave. (We recommended using steril-
ization bag with at least one paper side.) The motor should be processed in the autoclave set
for a minimum of 4 minutes at a sterilization temperature of 1320C / 2700F and a minimum
dry time of 30 minutes.
2. For sterilization of attachment handpieces:
• Follow sterilization instructions provided by the manufacture of the handpiece.
Note: Replace the O-ring if
• Water or air leaks occur,
• The handpiece vibrates abnormally,
• The supply of water or air cannot be stopped, or
• It is difficult to install or remove the handpiece.

• There is no specific replacement period.
Changing the O-ring
To replace the motor O-rings: (Fig.13)
Fig. 13
1. Squeeze the O-ring together between your thumb and forefinger to form a loop.
2. Pull the O-ring off the motor.
3. Repeat steps 1 and 2 for the other three O-rings.
4. Slide on the new O-rings
NOTE: Always replace all four O-rings to ensure a secure connection between the motor and
attachment.
To replace the two small O-ring at the motor connection
back end: (Fig. 14)
1. Lift up the O-ring with a pair of tweezers and remove
the O-ring.
2. Carefully replace the two O-ring with new ones.
Fig. 14
NOTE: The ISO 11498 standard stipulates a durability of at least 250 sterilization cycles. We
recommend that you have the Medilectric Micromotor serviced after 500 sterilization cycles
or one year, whichever comes first.
