VACUUM VALVE SERVICE & MAINTENANCE

PRIOR TO STERILIZATION
Minimize the potential accumulation of debris that could inter­fere with the operation of the instrument by flushing clean
water through it while working the valve lever open and
closed several times.

1. Using mild cleaner and water, wipe all surfaces of the
valve and dry with a clean, soft cloth.

OPERATOR’S GUIDE

BDS-2561 LEFT/RIGHT DUO DELIVERY SYSTEM

The Belmont BDS-2561 Left/Right cabinet mounted Duo Delivery System features an
automatic panel mount control for three handpieces, expandable to four with doctor ’s
3-way air/water syringe, master on/off with indicator, individual handpiece adjustment,
non-retraction water coolant with on/off, individual water coolant adjustment, 4-hole
Midwest oblate handpiece tubing, and a wet/dry type foot control.

2. Use a stiff HVE or SE cleaning brush of an appropriate
size to dislodge internal buildup.

NOTE

Do not ultrasonically clean, as instrument surface
finishes may be damaged.

PERIODIC MAINTENANCE
If the operation of the valve becomes sticky or stiff it may be
necessary to remove the valve spool for a thorough cleaning
and lubrication. Refer to the appropriate exploded view
shown in Figure 4.

1. Gently lift one end of the plastic on/off lever (V-1103/V-

1203) out from the indentation on the end of the spool.

2. Push the spool out of the valve toward that side and com­ pletely disengage the lever from the other end.

3. Clean the spool and inspect O-rings and replace those that
have nicks, cuts, flat spots or show signs of wear. Lubri­ cate O-rings with O-ring lube then reassemble the valve.

SURFACE DISINFECTION
Bleach or Sodium Hypochlorite solutions may permanently
damage the valve. Some surface disinfectants that will not
harm the valve are Birex SE, Sporicidin, Coldspor, Procide
Spray, Sterall Spray, Asepti-IDC, Biocide, Promedyne, Iodo­Five, Wescodyne, and Cavicide.

METHODS OF STERILIZATION
You may sterilize Belmont Autoclavable Valves by any of the
following methods: Chemical Vapor Method, Ethylene Oxide,
Steam Autoclave or Dry Heat.

OPERATING/CONTROL INSTRUCTIONS

All controls are located on the front panel. Figure 1 shows
the location and identifies the function of these controls.

MASTER ON/OFF

Turns on air and water for the complete system. Flip toggle
forward to activate system. Always turn the toggle OFF

when not in use.

MASTER ON/OFF INDICATOR

Provides visual proof that the system is pressurized when
the MASTER ON/OFF is in the ON position.

DRIVE AIR PRESSURE CONTROL

Allows handpiece to be adjusted to its manufacturer’s
recommended operating pressure. Turn the adjusting screw

counter clockwise to increase the pressure, clockwise to
decrease the pressure.

DRIVE AIR PRESSURE GAUGE

Indicates drive air pressure to the handpiece.

HANDPIECE FLUSH CONTROL

Activates handpiece high volume water flow through hand­piece water coolant lines. Flip the toggle up to activate the

system.

WATER COOLANT FLOW CONTROL

Allows adjustment to be made to the handpieces. Turn the
knob counter clockwise to increase the flow, clockwise to
decrease the flow.

Figure 2 shows automatic handpiece holder & syringe
holder assembly.

AUTOMATIC HANDPIECE HOLDER

Signals the automatic control system to supply drive air and
air/water coolants to handpiece as it is lifted from its holder.
When the handpiece is placed back into its holder, a signal
to the automatic control system stops the drive air and
air/water coolant supply.

CLEANING

BARRIER TECHNIQUE

The first choice in the protection of dental equipment should be the use of disposable barrier products. The repeated use of
disinfectants on equipment surfaces without the constant removal of the solution residue will eventually cause some damage
to equipment surfaces.

CHEMICAL DISINFECTION

The manufacturer of the disinfectant to be used should be contacted for them to state that the disinfectant will not damage
equipment surfaces including upholstery.

UNACCEPTABLE DISINFECTANTS

The following chemicals may damage equipment and upholstery:

* Alcohol based solutions
* Bleach
* Phenol/Alcohol combinations
* Foam spray products

USE WITH CAUTION

* Water based phenolic disinfectants following exactly the instructions for use.

BELMONT WARRANTY DOES NOT COVER DAMAGE TO EQUIPMENT AND UPOHOLSTERY CAUSED BY
DISINFECTANT SOLUTIONS.

TIP STERILIZATION

TROUBLE SHOOTING

1. To remove syringe tip, push in collar ring, then firmly grasp
tip and pull away from syringe head.

Solution: Replace the button assembly #3085. To
remove the button, hold buttons down,

2. After sterilization, replace the tip by pushing in collar ring
on syringe, then by inserting tip until it is firmly seated.

remove the retaining pin & gently lift under
the button. When re-installing the button, be
sure the spring is properly seated, with the

Release collar ring to lock tip securely to syringe.

smaller end facing upward. While holding
both buttons down, insert the retaining pin
through the syringe head.

NOTE

Be sure to rinse all cleaning agents from the tip prior to
sterilization. You may sterilize syringe tips by any of the
following methods; Chemical Vapor, Ethylene Oxide or
Steam Autoclave. Temperatures should never exceed

Alternatively, you may replace the O-rings on
the button assembly, using Syringe Repair Kit
#3066. After removing the button, slide the E­ ring from the stem, and pull the button from
the spool.

280 degrees Farenheit, (138 degrees Celsius).

Solution: Check first to ensure that the syringe tip is
undamaged and fully seated in the tip adapter

INSTALLATION

1. Turn off AIR and WATER supplies.

2. Unscrew syringe handle and determine which fitting leads
to the air button.

3. Slide syringe handle down over the syringe tubing. Select
the air side of the syringe tubing and connect to the air
fitting on the syringe.

4. Repeat with the water tubing to the water fitting. Ensure
that the unit end of the syringe tubing is properly connect­ ed to the air and water supply fittings on the dental unit.
Recommended operating pressures:
AIR 80 psi, WATER 40 psi.

assembly. If it is the O-ring (#2201) under the
tip adapter assembly it should be replaced.
Remove the tip, and use a 5/32 inch hex key
to unscrew the assembly from the syringe
head. Use a dental pick or a bent paper clip to
remove the small O-ring from the bottom of
the bore in the syringe body. Be careful not to
nick or scratch the sealing surfaces. The best
way to install the replacement O-ring is to slip
it onto the end of a syringe tip, apply silicone
lubricant, then insert it into the bore.

Before reinstalling the tip adapter assembly,
look down into the bore in the syringe body
and assure that the alignment pin is in place.
With the spring in place in the collar, align the
slot in the collar with the pin, then push the
collar into the syringe body. Tighten the
assembly firmly, holding the hex key by the
short end, with the long end inserted into the
tip adapter assembly. By holding the hex key
this way, you will have approximately the right
torque.
