Floor Boxes

Your Cascade, recessed, or stainless steel floor box
(see Figure 1) is mounted over the utilities on the
floor or wall of the operatory. Located in the floor
box are the air and water manual shutoff valves,
filters, and pressure pre-regulators. You will find
vacuum or gravity drains as well as electrical out­lets.

The stainless steel floor box covers lift off for
access to the utilities and optional power supplies
and/or water heater.

To remove the cover from your Cascade Floor
Box, slide the cover forward a little and lift.

The recessed floor box cover is held in place
by four screws. Removing the screws will allow
you to lift the cover.

NOTE

Do not use saline solution, mouth rinses, or any
chemical solutions not specified in this manual
in your municipal water supply. These may
damage the water system components and cause
the failure of your dental unit. If you need to use
such solutions, a water supply systemseparate
from your dental unit should be used. As a
general rule, water that is suitable for drinking is
suitable to use in your delivery system.

Shutoff Valves control the air and water to the
unit. To prevent leaks, these valves should remain
fully open (turned counterclockwise) except while
your unit is being serviced.

The Air-actuated Air and Water Shutoff Valves
automatically shut off air and water to the system
when the master on/off toggle is in the OFF position.
This safety feature prevents water damage in the
event the unit should develop a water leak while the
unit is unattended.

Filters prevent solids from entering the unit. The
procedures for checking and replacing the filters are
given on pages 10 and 11.

Pre-Regulators control the air and water
pressures in the unit. The procedure for adjusting
system pressure is given on page 8.

Your system may include A-dec’s 17 watt power
supply or 300 watt power supply. No cleaning
or maintenance is required to maintain the
power supply.

If a problem arises with the power supply or an
A-dec electrical accessory to the power supply,
call your authorized A-dec dealer.

The Gravity Drain (a “T” fitting) (see Figure 6) is

connected to the office waste drainage system and
provides for the disposal of water and debris from
the unit.

NOTE

The master on/off toggle switches the control
head, dental light, auxiliary cable, and the
indicator light on or off.

The Air Vent (the open end of the “T” fitting)
prevents air being trapped in the office waste
drainage system. If the vent becomes obstructed,
waste water and debris may backup into the unit.

If A-dec’s optional circulating warm water
syringe is included with your unit, a water drip
tube will be positioned over the drain air vent. The
drip tube is the outlet for warm water supplied to
your syringe by the water heater. For more
information about your syringe, refer to your

Autoclavable Syringe Owner’s Guide, A-dec
Publication No. 85.0680.00.

If A-dec’s optional Radius,Cascade, or Decade
Cuspidor is included with your unit, a flexible tube
from the cuspidor will be connected to the gravity
drain. For information about the gravity drain
cuspidor, refer to the Cascade 7284 and Radius

7285 Cuspidor Owner’s Guide, A-dec Publication
No. 85.2609.00 or Decade 7283 Owner’s Guide,
A-dec Publication No. 85.0685.00.

The office central vacuum system outlet is
located in the floor box. A flexible tube connects
your vacuum instruments and optional Cascade
or Decade vacuum cuspidor to the outlet.

For information about your assistant’s vacuum
instruments, refer to your Assistant’s

Instrumentation Owner’s Guide, A-dec
Publication No. 85.2610.00.

For information about the optional Cascade
vacuum drain cuspidor, refer to theCascade 7284

The air and water pre-regulators are located in
the floor box. Before making any adjustments,
verify that the air compressor is turned on, and
that it maintains 80–100 psi pressure in the
tank. If it doesn't, refer to the compressor
instructions.

System Air and Water Pressure
Adjustments

NOTE

When decreasing system air or water pressure,
you will not see the air or water pressure gauge
in the floor box 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.

1. Be sure that the manual shutoff valves are
fully open (counterclockwise). Turn the
system on and check the pressure gauges in
the floor box (see Figures 7 and 8). Air
pressure should be 70–80 psi while water
pressure should be 35–40 psi.

2. While watching the gauges, operate the
syringe. If the system air pressure drops by
any more than 15 psi, or water pressure by
more than 10 psi, check for clogged filters.

3. If adjustment of either the air or water
pressure is required, turn the appropriate
pre-regulator knob clockwise to increase
pressure, or counterclockwise to decrease.

Air and water pass through separate filters before
entering the regulators. A filter must be replaced
when it becomes sufficiently clogged causing
restricted flow to the regulator.

Checking for a Clogged Air Filter

To check for a clogged air filter, flip the master
on-off toggle to the ON position and remove the
floor box cover. While watching the air pressure
gauge in the floor box (see Figures 7 and 8), press
the syringe air button. If the air pressure indicated
by the gauge drops by more than 15 psi, the filter
element is clogged and must be replaced.

Checking for a Clogged Water Filter

To check for a clogged water filter, flip the master
on-off toggle on the control head to the ON
position, then remove the floor box cover. Watch
the water gauge, press the syringe water button. If
the water pressure drops by more than 10 psi, the
water filter is clogged and must be replaced.

Filter Maintenance

Inspecting the Filters

To inspect or replace a filter element, flip the
master on-off toggle to the OFF position, then close
the manual shutoff valves. Bleed the system of
air and water pressure by operating the syringe
buttons until air and water no longer flow. Using a
standard (flat-blade) screwdriver, remove the filter
housing from the air and/or water pre-regulators
assemblies (see Figure 9) and remove the filter.

If the filter is visibly clogged or discolored, you will
need to replace it.

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 9). The system will not work properly if the
filter is installed incorrectly.

The manual water shutoff valve in your floor
box (see Figure 10) is equipped with a screen to
prevent debris from entering the system. You
should periodically check and replace this screen
to ensure unrestricted water flow to your unit.

To remove or replace a screen, first move the
master on/off toggle to the OFF position and close
the manual water shutoff valve.

Now, using a 5⁄8" or adjustable wrench, loosen
the compression nut on the manual water shut­off valve and pull the water regulator out of the
shutoff valve (see Figure 10). Remove the screen
and install the replacement screen.

Reposition the water regulator in the manual
shutoff valve outlet and tighten the compression
nut. Open the manual water shutoff valve and flip
the master toggle to the ON position. Check the
fittings for leaks.
