Servicing SPH Dispensing Valves
Sanitizing the System
The syrup systems should be sanitized every 360 days by a qualified service technician following the sanitizer manufac-
turer’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.
Suggested Sanitizers
KAY-5® Sanitizer/Cleaner (100 PPM)
Mix one packet of KAY-5® Sanitizer/Cleaner per 2.5 gallons of tap water [70°-100°F (24°-35°C)] according to manufacturer's
instructions to ensure 100 PPM of available chlorine.
Household Bleach (200 PPM)
For 6% Sodium Hypochlorite bleach, mix 2.5 fl oz (75mL) in 5 gallons of tap water [70°-100°F (24°-35°C)]. For 5.25% Sodium
Hypochlorite bleach, mix 2.2 fl oz (66mL) of bleach in 5 gallons of tap water [75°-95°F (24°-35°C)]. This will ensure a bleach
solution of 200 PPM of available chlorine.

Assemble the dispensing valve. Rinse them with warm water, and place them on clean paper towels.
18.
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.
19.
Carefully install the valve with the caged o-ring in the dispensing valve body.
20.
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.
21.
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.
