When you begin to install your 

Wunder- Bar

® Mechanical Flex Hose bar 

dispenser, you will notice that all necessary mounting hardware, a hose 
hanger, a drip cup, a drain tube, and the appropriate number of stainless 
steel input fittings are included with each dispenser (

Fig.1

). 

The input fittings are installed in the product manifold of the dispenser. 
These input fittings are held in place by kwik klips. To remove input fittings, 
pull up on kwik klip just far enough to allow removal of the fittings (

Fig.2

). (It 

is not necessary to remove the kwik klip entirely).  

1/4” straight Input Fittings are included 
with all new 

Wunder-Bar® 

Post-Mix 

Beverage and Juice Dispensers unless 
custom “Fitting Sets” are ordered.  In-
put fittings are available in straight, 90 
degree, and 45 degree configurations 
with either 1/4”, 5/16”, 3/8", or 1/2" 
barbed ends.  3/8” and 1/2” Input Fit-
tings are available in two lengths: 
“short” and “long” (

Fig.3

) to allow the 

two lengths to be installed “staggered” 
to accommodate braided tubing.   

To make a tubing connection; remove the input fitting, secure the tubing to 
the fitting with a ferrule or Oetiker clamp, re-install fitting into correct posi-
tion on the manifold, push the kwik klip down fully to lock the input fitting 
into position. The letters and numbers on the manifold label correspond to 
the button positions on the dispensing handle. 

Use the two, 2" stainless steel wood screws, provided as part of the mount-
ing hardware package, to secure the tube collector/manifold assembly to 
the underside of the bar. (A Kwik Mount kit is also available as an optional 
item). It is recommended that a screw be placed in both the tube collector 
and the brix manifold to prevent unwanted flexing.
