NOTE: Use Dow-Corning DC-111 (P/N 321471000) light grade silicone lubricant to lubricate the O-rings.
Sanitizing the System
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.
Emptying a Barrel
To empty the barrel, perform the procedure in Table 38.
NOTE: The unit should be sanitized every 180 days by a qualified service technician following the sani-
tizer manufacturer’s recommendations.
Flushing the System of Syrup
After emptying the barrel, the barrel should be flushed of product before proceeding with the sanitizing procedure.
Perform the procedure in Table 39.
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 housing 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.
