Sanitizing The System; Emptying A Barrel; Flushing The System Of Syrup - Cornelius Viper E 2 Flavor Service Manual

Step
Lubricate the caged o-ring. Carefully install the caged o-ring onto the valve from the straight end (opposite
17.
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.
Install the spring fitting, knob and lever parts, torsion spring and spring housing assembly by reversing the
19.
removal procedure. Do not tighten down the hold-down plates securing the spring housing at this time.
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
20.
closed position after release. Do not overtighten. Overtightening results in a high activation force on the
valve.
NOTE: Use Dow-Corning DC-111 (P/N 321471000) light grade silicone lubricant to lubricate the O-rings.
