Master On/Off Toggle
The master on/off toggle
(see Figure 3) turns air, water, and
electricity on or off to the system.
CAUTION
The MASTER ON/OFF TOGGLE should be
in the OFF (0) position whenever the unit
is not in use.
This will prevent the possibility of water
damage should a leak occur while the unit is
unattended.
Making sure the unit is off will also
prevent the possibility of self-activation
and the resulting burn-out of your
electrical accessories.

Cascade 3181 & A-dec 4631 Duo Delivery Systems
Drive Air Pressure Controls
The drive air pressure controls (see Figure
3 on page 3) are used to adjust the drive
air pressure to each handpiece.
Adjust the drive air pressure to meet the handpiece
manufacturer’s dynamic drive air pressure
specification. Refer to the documentation that
came with your handpiece for the dynamic drive
air pressure specification.
Use a 3⁄32" hex key to complete this adjustment.
1. Install a bur in the handpiece.
2. Locate the drive air gauge on the front of the
control head (see Figure 2 on page 2).
3. Move the wet/dry toggle on the foot control
(see Figure 6 on page 9) to the OFF position,
away from the blue dot).
4. Turn the drive air control clockwise until the
valve seats.
5. Fully depress the foot control disc.
6. While running the handpiece, watch the
drive air gauge and adjust the handpiece
dynamic drive air pressure to meet
manufacturer’s specifications.
• Turn the drive air control counterclockwise to
increase drive air pressure flow.
• Turn the control clockwise to decrease flow.
NOTE
Do not turn the control counterclockwise
beyond the point where the drive air
pressure no longer increases. The control
adjustment screw may come completely out
of the unit.
7. Repeat steps 1 through 6 for each handpiece.
5
Cascade 3181 & A-dec 4631 Duo Delivery Systems
Coolant Air Flow Control
The coolant air flow control (see Figure 3
on page 3) is used to adjust the coolant
air flow to all handpieces.
Use an adjustment key (see Figure 4 on page 3) or a
1⁄8" hex key to complete this adjustment.
1. Install a bur in the handpiece.
2. Locate the coolant air control
(see Figure 3 on page 3).
3. Move the wet/dry toggle on the foot control
(see Figure 6 on page 9) to the OFF position,
away from the blue dot.
4. Insert an adjustment key, or a 1⁄8" hex key,
into the coolant air flow control.
5. Fully depress the foot control disc to activate
the handpiece.
6. Adjust the coolant air flow to fit your needs.
A strong flow of air is recommended.
• Turn the control clockwise to decrease the flow.
• Turn counterclockwise to increase the flow.
7. The coolant air has been set for all handpieces.
6
Cascade 3181 & A-dec 4631 Duo Delivery Systems
Coolant Water Flow Controls
The coolant water flow controls are used
to adjust the flow of coolant water to
each handpiece (see Figure 3 on page 3).
Use an adjustment key (see Figure 4 on page 3) or a
1⁄8" hex key to complete this adjustment.
1. Install a bur in the handpiece.
2. Locate the coolant water flow controls
(see Figure 3 on page 3).
3. Move the wet/dry toggle on the foot control
(see Figure 6 on page 9) to the ON position,
toward the blue dot.
4. Insert an adjustment key, or a 1⁄8" hex key,
into the coolant water flow control for the
handpiece being adjusted.
5. Hold the handpiece over a receptacle. Hold the
handpiece so that the water will be directed
away from you and into the receptacle.
Then fully depress the foot control disc to
activate the handpiece.
6. Adjust the coolant water flow to fit your needs.
• Turn the control clockwise to decrease the flow.
• Turn counterclockwise to increase the flow.
7. Adjust the coolant water for each handpiece.

Cascade 3181 & A-dec 4631 Duo Delivery Systems
Handpiece Tubing Flush
The handpiece tubing flush system
flushes more water through the tubings
in less time than is normally possible
when operating only the foot control.
Disconnect the handpieces before
flushing the tubings.
After each patient, the handpiece tubing should
be flushed for about 20–30 seconds.
At the beginning of each day, the handpiece
tubing should be flushed for about 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 5).
Insert an adjustment key or 1⁄8" hex key into the
handpiece tubing flush control on the side of the
control head. 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.

Foot Control
The foot control modulates drive air to the active
handpiece and provides an air signal that
activates the coolant air and coolant water flow.
The foot control is operated by light foot pressure
applied to any part of the foot control disc.
The foot control is equipped with a wet/dry toggle
and can be equipped with an optional chip blower
button (see Figure 6).
Wet/Dry Toggle. Allows you to shut off the
coolant water to the handpiece without moving
your hands from the oral cavity. Using your foot,
move the toggle away from the blue dot to turn
the coolant water OFF. Move the toggle toward the

Handpiece Dry Block Conversion
The handpiece control system has one to four
handpiece control blocks with coolant water to the
handpiece. 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
1. Move the master on/off toggle to the OFF position. Bleed the system water by operating the
syringe and flushing the handpiece tubings.
2. Locate the handpiece control block position
that will be the dry block. Access the control
blocks underneath the control head.
3. Use a 3/32" hex key to remove the large red
cartridge from the control block. Install the
large black cartridge from the dry block conversion kit into the control block (see Figure 13).
4. Use a 3/32" hex key to remove the small blue
cartridge from the same control block. Install the
small black cartridge from the dry block conversion kit into the control block (see Figure 13).
5. Turn your handpiece control system on, then
check the function of the dry block handpiece
conversion. A small amount of residual water
may be discharged from the handpiece tubing
but should dry after a few seconds.

Cascade 3181 & A-dec 4631 Duo Delivery Systems
System Air Pressure Adjustments
The air pre-regulator is located in the utility
area inside the cabinet base. Before making
any adjustments, verify that the air compressor is turned on and that it maintains 80–100
psi (552–690 kPa) pressure in the tank. If it
doesn’t, refer to the compressor instructions.
1. Be sure that the manual shutoff valve is fully
open (counterclockwise). Turn the system ON,
and check the pressure gauge in the utility
area (see Figure 19). Air pressure should be
70–80 psi
(483–552 kPa)
2. While watching the gauge, operate the
syringe. If the system air pressure drops by
any more than 15 psi (103

NOTE
When decreasing system air pressure, you
will not see the air gauge in the utility center
change until you relieve pressure from the
system. Activate the syringe for a few
seconds, then check the gauge. Repeat this
process each time you make an adjustment
to decrease pressure.
4. Test the unit by operating the syringe and
handpieces for several seconds. Make sure
the air pressure is maintained.

Filter Maintenance
Air Filter Element
Air passes through a filter before entering the
regulator. A clogged filter can restrict flow to the
regulator and should be replaced immediately.
Checking for a Clogged Air Filter
To check for a clogged air filter, move the master
on/off toggle to the ON position, then remove the
utility area cover under the control head. While
watching the air pressure gauge in the utility area
(see Figure 20), press the syringe air button. If the
air pressure indicated by the gauge drops by more
than 15 psi (103 kPa), the filter element is clogged
and must be replaced.

Inspecting the Filter
To inspect or replace a filter element, move the
master on/off toggle to the OFF position, then close
the manual shutoff valve. Bleed the system of air
pressure by operating the syringe buttons. Using a
flat-blade screwdriver, remove the filter housing
from the air pre-regulator assembly (see Figure 20)
and remove the filter.
If the filter is visibly clogged or discolored,
replace it. Order A-dec Part No. 24.0234.00, or
24.0234.01 for a package of six.
When installing a new filter, notice that one end of
the filter has a beveled edge. Install the filter with
the beveled edge facing the manifold (see Figure
20). The system will not work properly if the filter is
installed incorrectly.
