A. General Description
Midmark delivery systems are intended to provide dental professionals with air & water to operate dental
handpieces, syringes, and Midmark authorized accessories during dental examinations and
procedures.
© Midmark Corporation 2000 SF-1621 Rev. 1/13
With the air manual shut-off valve open, unregulated air
is supplied to the Master ON/OFF switch on the delivery
unit [thru 1/8 in. purple tubing]. When the Master ON/
OFF switch is turned ON, air passes thru the ON/OFF
switch valve to the pilot air manifold [thru 1/8 in. red tubing]. The pilot air manifold directs the flow of air to the
handpiece holder valves, flex arm unlock buttons, and
back to the air and water master pilot shut-off valves in
the junction box [thru 1/8 in. red tubing].
Master Pilot Shut-Off Valves
The air from the Master ON/OFF switch opens the air
and water master pilot shut-off valves allowing air/water
to pass thru the master pilot shut-off valves to the air/
water regulators.
The air regulator w/gauge provides air to the foot control throttle valve [thru 1/4 in. grey ribbed tubing] and air
to the syringe and cuspidor [thru 1/8 in. yellow tubing].
This regulator should be set at 80 PSI to optimize performance.
The air regulator w/o gauge provides 30 PSI to
pressurize the water bottle [thru 1/8 in. brown tubing].
This regulator is preset at the factory and should not be
adjusted.
An updated in-line regulator currently provides 30 PSI
to the water bottle replacing above mentioned regulator.
Description and Theory of Operation
Systems are available in various styles and configurations [Procenter-style (console, L/R, & 12:00 casework
mounted), & Whip-style (console & L/R mounted)].

SECTION I
GENERAL INFORMATION
C. Basic Theory of Operation
Whip-style Delivery Units (Figure 1-1)
With the selector valve toggle switch in City or Bottle
position, [city water or distilled water] flows thru the
selector valve to the water supply manifold [thru 1/8 in.
blue tubing]. The water supply manifold directs the flow
of water to the syringe adjustment valve and the handpiece adjustment valves [thru 1/8 in. blue tubing].
NOTE: The outgoing water line from the selector valve
is used for both City and Bottle water.
Master ON/OFF Switch (1, Figure 1-1)
Foot Control Assembly
Pilot Valve Block
When the foot control pedal is depressed, the throttle
valve [in foot control] opens, and supplies drive air and
coolant air for the handpieces.
The pilot valve block directs the flow of air, city water,
and self contained water throughout the system
Drive air is supplied to the handpiece supply drive air
manifold [thru 1/4 in. clear tubing]. The handpiece supply drive air manifold directs the flow of air to the handpiece drive air adjustment valves [thru 1/4 in. clear
tubing]. The drive air is regulated by the adjustment
valves then directed to the kink valves [thru 1/4 in. clear
tubing]. Coolant air is supplied to the handpiece coolant
air adjustment valve [thru 1/8 in. green tubing]. The
coolant air is regulated by the adjustment valve then
directed to the kink valves [thru 1/8 in. green tubing].
When the Wet / Dry toggle valve [on foot control] is
switched to the Wet position, pilot air for coolant water is
supplied to the kink valve manifolds [thru
1/8 in. orange tubing]. The kink valve manifolds direct
the pilot air to the coolant water adjustment valves [thru
1/8 in. white tubing]. The pilot air opens the coolant
water adjustment valves, allowing water to flow to the
kink valves [thru 1/8 in. blue tubing].
Kink Valve Assembly
When a handpiece is removed from holder, the activation lever is released. This causes the (normally closed)
handpiece holder valve to stop the airflow to the kink
valve manifold [thru 1/8 in. purple tubing] and allows the
kink valve to open. When the kink valve opens, coolant
air, drive air, and coolant water flow thru the kink valve
to the handpiece.
Adjustment Knobs (See Figure 1-1 for location)
Allow user to adjust air & water flow to instruments.
[Refer to Section V for diagrams]
When the Master ON/OFF switch is turned ON, air
passes through the ON/OFF switch valve to the pilot
valve block.
Water Selector Valve (2, Figure 1-1)
Distilled water is supplied to the selector valve from the
water bottle [thru 1/8 in. blue tubing]. City water is supplied to the selector valve from the water regulator [thru
1/8 in. blue tubing].
With the selector valve toggle switch in City or Bottle
position, [city water or distilled water] flows thru the
selector valve to the water supply manifold [thru 1/8 in.
blue tubing]. The water supply manifold directs the flow
of water to the syringe adjustment valve and the handpiece adjustment valves [thru 1/8 in. blue tubing].
NOTE: The outgoing water line from the selector valve
is used for both City and Bottle water.
Foot Control Assembly
The foot control supplies drive air and coolant water to
handpieces. When the water ON/OFF switch is turned
ON, the coolant water valve opens allowing
coolant water to flow to handpieces.
Handpiece Operation
When a handpiece is lifted, the whip assembly pivots
causing a pilot valve to close. This action shuts off the
pilot air to the kink valve causing the valve to relax the
tubing, allowing air flow thru the kink valve tubing.
Kink Valve Assembly
When the pilot valve opens, pilot air flow shuts off to the
kink valve allowing it to relax. This allows coolant air,
drive air, and coolant water to flow through the kink
valve tubing to the handpiece.
Adjustment Knobs (See Figure 1-1 for location)
Allow user to adjust air & water flow to instruments.

Cuspidor (Figure 1-2)
[Refer to Section V for diagrams]
Supply Water
With the water manual shut-off valve [in junction box]
open and the Master ON/OFF switch [on delivery unit]
ON, the master pilot shut-off valve supplies regulated
water to the cup fill flow control valve and the bowl flush
control pinch valve in the cuspidor [thru 1/4 in. blue tubing]. The cup fill flow control valve regulates the supply
water, then directs the water to the cup fill water valve
[thru 1/4 in. blue tubing]. The bowl flush control pinch
valve regulates the supply water, then directs the water
to the bowl flush water valve [thru 1/4 in. blue tubing].
Supply Air
With the air manual shut-off valve [in junction box] open
and the Master ON/OFF switch [on delivery unit] ON,
the air regulator w/gauge supplies 80 PSI to the two
manually operated cup filler valves, cup filler primary air
valve, bowl flush solenoid, and the manually operated
bowl flush valve.
Figure 1-2. Cup Fill / Bowl Flush Buttons
Cup Fill (Current Versions)
Cup Fill (Earlier Versions)
When one of the manual cup fill valve buttons (1,
Figure 1-2) is depressed, air is supplied to the (normally
open) cup fill pilot air valve [thru 1/8 in. white tubing]. Air
passes thru this valve to the cup fill timing adjustment
valve and to the (normally closed) cup fill primary air
valve [thru 1/4 in. yellow tubing]. The air opens the normally closed valve and supplies pilot air to the cup fill
water valve and back to the (normally open) cup fill pilot
air valve [thru 1/8 in. red tubing]. The pilot air to the cup
fill water valve opens the valve and allows water to flow
to the cup fill faucet. The pilot air to the (normally open)
cup fill pilot air valve closes the valve, trapping air in the
1/4 in. yellow tubing between the pilot and primary air
valves. This allows the cup fill faucet to run until air
pressure in the 1/4 in yellow tubing is “bled off” thru the
cup fill timing adjustment valve.
NOTE: The cup fill timing adjustment valve may be
adjusted to shorten/lengthen the amount of time it takes
to bleed off air pressure.
© Midmark Corporation 2000 SF-1621 Rev. 4/13/13
when the manual cup fill valve button is depressed, pilot
air is supplied to the shuttle valve. The shuttle valve
blocks off the air line going to the opposite cup fill valve,
and supplies pilot air to the cup fill water valve as well
as the cup fill timing adjustment valve [thru 1/8” red tubing]. The pilot air opens the cup fill water valve allowing
water to flow to the cup fill faucet.
The cup fill timing adjustment valve gradually bleeds off
air pressure from the cup fill water valve. When air pressure is removed from the cup fill water valve, the valve
closes and water flow to the cup fill faucet is stopped.
NOTE: The cup fill timing adjustment valve may be
adjusted to shorten/lengthen the amount of time it takes
to bleed off air pressure.

Bowl Flush
For Procenter Cuspidor Mounted on Elevance Chair
ONLY
Manual Push Button Operation
When the manual bowl flush valve button (2, Figure 1-2)
is depressed, pilot air is supplied to the bowl flush water
valve as well as the bowl flush timing adjustment valve
[thru 1/8 in. red tubing]. The pilot air opens the bowl
flush water valve allowing water to flow to the bowl flush
faucet. The bowl flush timing adjustment valve gradually
bleeds off air pressure from the bowl flush water valve.
When air pressure is removed from the bowl flush water
valve, the valve closes and water flow to the bowl flush
faucet is stopped.
NOTE: The bowl flush timing adjustment valve may be
adjusted to shorten/lengthen the amount of time it takes
to bleed off air pressure.
Cupidor Position Mode Setting
Press button 4 to raise chair (patient) to the cuspidor
position, a position convenient for cuspidor use. The
cuspidor solenoid output also activates on the PC
board. The cuspidor solenoid ouput (J5) can be connected to an optional automatic bowl flush solenoid,
initiating an automatic bowl flush function as the chair
raises to the cuspidor position. Press button 4 again to
return chair to last position used before the cuspodor
positon.
1.) Positon (1) on dipswitch - Position (4) on remote
2.) Chairboard sends signal to cuspidor board
Automatic Bowl Flush Function
When using the cuspidor with a Midmark dental chair,
the operator may program a “Patient Cuspidor Position”
on program button 4. This moves the chair to a desired
position, and electrically activates the cuspidor bowl
flush solenoid.
With the chair PC board in Cuspidor Position Return
Mode, pressing program button 4 begins to move the
chair to the programmed position and the PC board
supplies voltage to the bowl flush solenoid (until chair
reaches the programmed position). This voltage causes
the solenoid to open, allowing pilot air to flow to the bowl
flush water valve as well as the bowl flush timing adjustment valve [thru 1/8 in. red tubing]. The pilot air opens
the bowl flush water valve allowing water to flow to the
bowl flush faucet. The bowl flush timing adjustment
valve gradually bleeds off air pressure from the bowl
flush water valve. When air pressure is removed from
the bowl flush water valve, the valve closes and water
flow to the bowl flush faucet is stopped.
NOTE: The bowl flush timing adjustment valve may be
adjusted to shorten/lengthen the amount of time it takes
to bleed off air pressure.
