The syrup systems should be sanitized every 180 days by a qualified service 
technician following the sanitizer manufacturer’s recommendations or when 
changing syrup types. 
The sanitizing process consists of emptying the barrel, washing the lines and 
barrel, cleaning the BIB connectors, rinsing and refilling the system.

To empty the barrel, perform the procedure in Table 38.

9. 

Remove the knob, spring, sleeve, and lever from the dispensing valve.

10. 

Remove spring fitting from dispensing valve.

11. 

Press the valve with the caged O-ring, down and out of the dispensing valve 

body.

12. 

Carefully remove the caged O-ring from the valve.

13. 

Wash all the parts in warm water. Remove all traces of syrup and lubricant, 

especially from the faceplate, o-rings, and dispensing valve. If parts are 

excessively coated, wipe clean with a paper towel to remove excess syrup 

and lubricant, especially from caged o-ring and dispensing valve. Use a brush 

(provided with the unit) to clean the faceplate relief valve passages and the 

inside of the knob.

14. 

Submerge all the parts in a 4-percent solution of approved sanitizing agent for 

the amount of time recommended by the sanitizer manufacturer.

15. 

Remove the parts from the sanitizing solution and place them on clean paper 

towels.

16. 

Assemble the dispensing valve.

17. 

Lubricate the caged o-ring. Carefully install the caged o-ring onto the valve 

from the straight end (opposite tapered end). Lubricate the grooves that the o-

ring rides to fill in all void areas around the o-ring.

18. 

Carefully install the valve with the caged o-ring in the dispensing valve body.

19. 

Install the spring fitting, knob and lever parts, torsion spring and spring hous-

ing assembly by reversing the removal procedure. 

Do not tighten down the 

hold-down plates securing the spring housing at this time.

20. 

After re-installing the faceplate, turn the dispensing valve spring housing to the 

left (counterclockwise) to put tension on the tension spring. Apply just enough 

tension so that the dispense valve shaft returns to the closed position after 

release. 

Do not overtighten. Overtightening results in a high activation force 

on the valve.

1. 

From the Barrel Status menu, press the DFRST button.

2. 

When the barrel is defrosted, go to the Maintenance menu. If the security fea-

ture is active, access the Maintenance menu by by pressing and holding the 

far left and right buttons simultaneously for approximately five seconds.
