Apply a bead of Silicone 

around the base of the Top 

Housing above the counter 

to prevent spilled soap 

from going through the 

mounting hole.

5.  Thread the Stem Locking 

Nut onto the Stem. The 

ribs on the Nut are to 

be towards the top. 

Once it goes past the 

two red o-rings, the nut 

will automatically stop 

threading.

NOTE:

 Make sure the fiber 

optic cables and the plastic 

tubing are 

OUTSIDE

 of the 

stem locking nut.

6.  Attach the tubing to the top 

barb of the Foam Mixer 

Housing.

7.  The Bottle Cap can only 

be placed onto the Stem 

in one orientation. The 

flat section on the Stem is 

to be aligned with the flat 

section on the Bottle Cap.

8.  Rotate the Bottle back and 

forth to align the flat section 

of the Stem to the flat 

section on the Bottle.

9.  Push the Bottle Assembly  

up onto the Stem while 

also inserting the Foam 

Mixer Housing into the hole 

in the post on the Bottle 

Cap.

 

Fully insert the Bottle 

Assembly over the Stem 

until it stops. Both red 

o-rings must be inside the 

Bottle Cap.

10. While pushing upwards on 

the Bottle, Thread the Stem 

Locking Nut down onto the 

Bottle Cap threads

NOTE: 

After assembly, hold 

the Stem and lightly rotate the 

Bottle back and forth and tug 

down to be sure it is on tight. If 

it is loose, repeat Steps 7 and 

8.

NOTE: 

Tug Tubing on Foam 

Mixer Housing down from 

under the counter to straighten 

out the tubing.

11.  Connect the small diameter 

tube from the Foam Mixer 

Housing to the air tube 

adapter barb located on the 

Bottom Housing.

12. Slide the Fiber Optic 

Nut over the Fiber Optic 

Cables. 

13. Insert the Fiber Optic 

Connector Tip Assembly 

into the bottom housing. 

Keyed feature on the 

Connector Tip ensures 

Fiber Optic Cables are 

always located properly.  

Thread the Fiber Optic Nut 

onto the Connector Port 

and hand snug tighten.  

NOTE:

 DO NOT bend or kink 

Fiber Optic Cables.

14.  Align the Top Assembly 

above the counter to the 

desired position and tighten 

the Mounting Nut against 

the bottom of counter so 

the Top Assembly does not 

easily rotate. Make sure 

Fiber Optic Cables are not 

between the underside 

of the counter and top of 

Mounting Nut. See Steps 4 

and 5.

15. Mount Battery Pack on 

wall nearest dispenser.
