SERIES 5 SIDE DELIVERY SYSTEM

Instructions For Use

The dental unit is equipped with a handpiece flush system that allows you to periodically flush fresh water through the 
handpiece tubings. The need for this is caused by the low flow of water through the tubings during normal use, which 
can lead to stagnation and the potential growth of “biofilm” contamination.

It is recommended that you flush the tubings at the beginning and end of each day. This may be done with or without 
the handpieces installed, but having the handpieces on the tubings will restrict flow, so a longer flush time will be 
required.  All of the tubings are flushed simultaneously. Hold them together and direct them into a basin, sink or 
cuspidor to catch the water. Flip and hold the flush 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 flushing and the use of antibacterial solutions in the 

self-contained water system.

MAINTENANCE

Equipment 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.

GENERAL CLEANING

CAUTION: 

Do not use powdered cleansers, scouring pads or abrasive scrubbers on any of the 

painted, plastic or metal surfaces of this dental unit. To remove dried-on material, use a soft bristled 
brush and a solution of mild detergent.

HANDPIECE FLUSH - DAILY MAINTENANCE

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.
