Lavatory-Mounted Soap Dispensers with Under-the-Counter Soap Reservoir

Bobrick Models B-922 and B-9226

Piston, Spout &

Cover Assembly

HOW TO MOUNT THE SOAP DISPENSER:

1. Unscrew the retaining nut from shank. Remove the spring washer.

2. Make sure the lavatory or countertop surface around the 1'' (25mm) diameter mounting
hole is clean and free of soap residue. Place supply tube and shank of soap dispenser
through mounting hole.

Make sure the plastic and rubber washers are in place between the

escutcheon and lavatory or countertop.

3. Position spout over lavatory. Make sure the spout is aligned with rectangular hole in
escutcheon (spout snaps into this position).

4. Place spring washer and retaining nut onto shank under the lavatory or countertop. Thread
the retaining nut up

only until finger-tight

against the underside of lavatory or countertop.

HOW TO INSTALL THE SOAP RESERVOIR SYSTEM:

CAUTION: The following instructions are a general guide only. Variations in design and
construction of installations, such as location of plumbing, will affect the exact location of
different elements of the system. This system has been designed for great adaptability by
allowing on-site measuring and cutting of the black flexible hoses, clear elbows, and pipe
connections as required.

The wall surface on which the soap reservoir is to be mounted determines the specific
type of mounting required for best installation:

For plaster or dry wall on studs, provide concealed backing and 1/4'' (6mm) screws to
secure system to wall. Backing must comply with local building codes.

For brick, concrete, or solid tile walls, provide fiber plugs or expansion shields for use
with 1/4'' (6mm) mounting screws.

1. Mount one coupling tee for each soap dispenser. The centerline of the coupling tee
should be within 6'' (150mm) of the soap dispenser centerline.

hose and supply tube compensate for any offset alignment.

Note: The black flexible

Use one coupling tee as a
template to mark the mounting hole locations on the wall for 1/4'' (6mm) mounting
screws.

2. Layout and cut the pipe connections as required to connect all coupling tees and end­caps. Pipe connections are to 3'' (75mm) ABS or PVC schedule 40 with 3-1/2'' (90mm)
outside diameter (88–90mm ABS or PVC Nominal pipe sizes).

3. Provide ABS/PVC or other multipurpose primer and pipe cement. Prime and glue pipe
connections to the coupling tees and end-caps to create a continuous line of piping.

4. Mount the piping

plumb and level

to insure a consistent soap depth throughout the

reservoir system.

5. Thread the plugs and o-rings into the drain holes on the underside of clear
elbows.

CAUTION: Do not overtighten the pipe plugs as this may cause the clear
elbows to crack.

6. Reduce the length of each clear elbow, if required, by cutting
from the large open end.

7. Use ABS/PVC primer and pipe cement to connect
each clear elbow to the appropriate coupling tee
with the small opening on top pointing up
toward the soap dispenser.

8. Place either end of the black flexible hose onto
the small opening on top of the clear elbow. Then
take the remaining length of hose and hold it up to the
shank of the appropriate soap dispenser to determine
where to cut the hose. The hose must overlap the shank 2''
(50mm) minimum.

9. Use ABS/PVC pipe cement to connect the bottom end of each black
flexible hose to the small opening of the clear elbow. Then slide the top end of
the black flexible hose up over the threaded shank of the soap dispenser. The
hose should overlap the shank 2'' (50mm) minimum.

CAUTION: Do not seal the top

end of hose — it must be left unsealed to allow for venting of soap reservoir.

10. Cut at an angle each soap dispenser's supply tube so the end reaches the bottom of
the clear elbow.

CAUTION: Do not stretch the supply tube tightly while cutting as this

may result in the supply tube being too short.

11. Insert supply tube through black flexible hose, making sure the angled end reaches
the bottom of the clear elbow and that the tube is not kinked.

12. After pipe cement has set, run water through the soap reservoir to test for leaks. Drain
the reservoir by removing the pipe plugs from the clear elbows.

HOW TO REFILL THE SOAP RESERVOIR:

1. On any one of the soap dispensers, turn the escutcheon clockwise slightly until it stops.

2. Insert the longest projection at end of BobKey into the rectangular hole of escutcheon; push straight in.
While holding BobKey in, turn cover counterclockwise about 1/8 turn.

3. Lift out the soap pump assembly enough to allow access to the entire shank opening for top filling. Lay the
soap pump assembly conveniently aside on the lavatory or countertop while filling system; the supply tube
can be left inserted in the shank.

4. Fill soap reservoir with soap. Watch the soap level in one of the clear elbows while filling. Do not over fill.
Use commercially marketed all purpose hand soaps.

Designer's Note:

and lotion soaps, synthetic detergents, and antibacterial soaps containing PCMX and or Triclosan. Bobrick soap dispensers are NOT
designed to dispense alcohol-based hand sanitizers or iodine-based surgical soaps.

Bobrick liquid soap dispensers are designed to dispense commercially marketed all purpose hand soaps including liquid

Note: An average system with three soap dispensers 30" (760mm) apart and a total pipe length of 7½ ft. (229cm) will have a capacity of

approximately 3.0 gal. (11.4 L).

5. Replace soap pump assembly. Secure the escutcheon by turning it clockwise until lock snaps into position.

MAINTENANCE:

1. Never use abrasive cleaners on the soap dispensers.

2. The soap pump assembly should be removed from system and flushed by pumping warm water through it every six months.

3. At least once a year, flush the soap reservoir with warm water. Drain the system by removing the threaded plugs from the clear elbows.

CAUTION: Do not use solvents that could damage the ABS pipes.
