2.5 VALVES (CONTINUED)
B. Volumetric Valve Cleaning and Sanitizing Procedures
NOTE:
The Volumetric Valve is an optional use valve with the Global tower. See Lancer
Maintenance Manual 28-0301/02 for complete information and adjustment procedures. This manual
is available on the Lancer web site (www.lancercorp.com).
1. Daily Nozzle/Diffuser Cleaning (See Figure 2)
Use the following procedures to clean the nozzle, and the
diffuser assembly, each day:
a. Remove nozzle by twisting it counter-clockwise

pulling
it
down.
b. Pull the diffuser assembly down to remove it from
the
valve.
c. Wash the nozzle and diffuser with warm water.
d. If needed, apply 111 lubricant to the o-ring on the
diffuser assembly. Then, carefully press it into the
diffuser mounting area on the underside of the
valve.
e. Make certain the nozzle o-ring, is in place around
the nozzle mounting area on the valve.
NOTE:
If necessary, slide a new nozzle o-ring onto the
nozzle

area.
f. Install the nozzle by inserting it into the bottom plate and twisting it clockwise to lock it
in
place.
2. Monthly Nozzle/Diffuser Sanitizing
Use the following procedures to sanitize the nozzle, and the diffuser assembly, once a
month.
a.
Cleaning
Solution

solution should be 2% sodium hydroxide.
b.
Sanitizing
