Coolant Water Flow Controls
The handpiece tubing flush system
flushes more water through the tubings
in less time than is normally possible
when operating the foot control only.
The handpieces should not be connected
when flushing the tubings.
How Often Should the Handpiece Tubings be Flushed?
After Each Patient:
Flush the tubings for about 20–30 seconds.
At the Beginning of Each Day:
Flush the tubings for 2–3 minutes.
Flushing the Handpiece Tubings
Gather up all the handpiece tubings that use
coolant water and hold them over a sink, cuspidor
bowl or basin. Be sure you hold the tubings so that
the water will be directed away from you and into
the receptacle (see Figure 7).
Insert an adjustment key or 1⁄8" hex key into the
handpiece tubing flush control on the side of the
control head (see Figure 7). Push in and hold the key
for the appropriate time required, either for flushing
between patients or flushing at the beginning of
each day, depending on the situation. Remove the
key and replace the tubings in their holders. Be
careful to replace each in the proper holder.

Your Cascade handpiece control system has one to
four handpiece control blocks with coolant water to
the handpiece. In some cases a control block without
coolant water, a dry block, is required. If you require a
dry block (offering no water to the handpiece) on
your handpiece control system, a dry block
conversion kit has been included with your system.
Installing the Dry Block Conversion Kit

position. Bleed the system water by operating
the syringe and flushing the handpiece
tubings.
2. Locate the handpiece control block position
