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.
Publication Number: 621360241LOEWSE
Defrost freeze cylinders, shut unit down, disconnect electrical power from Unit.
Perform the procedure in Table 41 to empty the barrels.
Remove the hex nuts and flat washers securing the faceplate to the freeze
barrel, then remove the faceplate from the barrel.
Carefully remove the large o-ring from the faceplate.
Unscrew the relief valve from the faceplate.
Disassemble the dispensing valve (see Figure 33).
Remove the two screws and hold-down plates securing the spring housing to
the dispensing valve body, then remove the housing.
Remove the torsion spring from the dispensing valve.
Remove the knob, spring, sleeve, and lever from the dispensing valve.
Remove spring fitting from dispensing valve.
Press the valve with the caged O-ring, down and out of the dispensing valve body.
Carefully remove the caged O-ring from the valve.
Wash all the parts in warm water. Remove all traces of syrup and lubricant, espe-
cially 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.
Submerge all the parts in a 4-percent solution of approved sanitizing agent for
the amount of time recommended by the sanitizer manufacturer.
Remove the parts from the sanitizing solution and place them on clean paper
towels.
Assemble the dispensing valve.
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.
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 hous-
ing assembly by reversing the 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 closed position after
release. Do not overtighten. Overtightening results in a high activation force
on the valve.
