The control system is equipped with a handpiece ush
system that allows you to periodically ush fresh water
through the handpiece tubings. The need for this is caused
by the low ow of water through the tubings during normal
use, which can lead to stagnation and the potential growth
of “biolm” contamination.
We recommend that you ush the tubings at the beginning
and end of each day. This may be done with or without
handpieces installed, but having handpieces on the
tubings will restrict ow, so a longer ush time will be
required.
MAINTENANCE
Care of the Unit
Asepsis Automatic Control
Control Head and Arm
The control head and post can be cleaned with a solution
of mild detergent and warm water. A variety of surface
disinfectants are available for use in dental treatment
rooms. Some of these can cause discoloration of painted,
plated or anodized surfaces with repeated use. This can
be minimized by careful adherence to the disinfectant
manufacturer’s instructions and by frequent washing with
soap and water.
IMPORTANT: Do not use powdered cleansers,
scouring pads or abrasive scrubbers on any of
the painted, plastic or metal surfaces of this den-
tal unit. To remove dried-on material, use a soft-
bristled brush and a solution of mild detergent.
Handpiece Flush — Daily Maintenance
The weekly cleaning procedure should be performed at
least once a week, preferably at the start of the week
before treating patients. If the unit is to be stored for any
length of time, perform the weekly maintenance routine
immediately before and after storage.
1. Purge the unit with air.
2. Flush the system with disinfectant solution:
a. Turn the unit off. Empty the water bottle, replacing
the water with cleaning solution (see Disinfectant
Solution, next page).
b. Hold the handpiece tubings and syringe over the
cuspidor or other suitable container. Turn the unit
on, wait a few moments, then operate the ush
toggle, syringe and foot control until a continuous
stream of solution is running through the system.
3. Allow the disinfectant to remain in the unit for 10 to 20
minutes, then ush the system again until all the
solution is used up.
WARNING: In order to mitigate the risk of cross-
contamination between patients,
disinfection and sterilization of handpieces
must occur after each dental procedure.
Refer to the handpiece manufacturer’s
instructions and recommendations for
sterilization or disinfection procedure.
All of the tubings are ushed simultaneously. Hold them together and direct them into a basin, sink or cuspidor to catch
the water. Flip and hold the ush toggle.
Allow adequate time for fresh water to make its way through the entire system and displace all standing water. The
American Dental Association and the Centers for Disease Control can provide additional recommendations regarding this
procedure, including information on frequency and duration of ushing and the use of antibacterial solutions in the self-
contained water system.
4. Purge the unit with air:
a. Hold the handpiece tubings and syringe over a
container. Turn the unit on, wait a few moments, then
operate the ush toggle, syringe and foot control until all
solution is purged from the system.
b. Turn the unit off. (If the unit will be stored, stop here.)
5. Fill with clean water:
a. With the unit turned off, remove the empty disinfectant
bottle. Replace with clean bottle and water.
b. Hold the handpiece tubings over a suitable container.
Turn the unit on, wait a few moments, then operate the
ush toggle until a continuous stream of water is owing
through the system. Replace handpieces and do the
same with the syringe. The unit is now ready for use.
Weekly Maintenance
Handpiece Oil Collector:
Replace the 2 x 2 gauze with a clean gauze in the
handpiece oil collector every 90 days or more often if
handpieces are oiled frequently.
