SECTION 7
CLEANING PROCEDURE
NOTE:
Cleaning procedure is only a suggestion. Customer is ultimately responsible for a sanitation procedure that
meets their requirements and standards.
CAUTION: De
-
pressurize the system before opening the pressure tank for any reason.
PROCEDURE:
1)
Turn the auto
-
refill switch on the main control panel to the
“
OFF
”
position (if applicable).
2)
Close the ball valve on the tank
’
s incoming air inlet port.
3)
De
-
pressurize the pressure tank by opening the regulator and pulling the ring on the tank
’
s safety valve for a fast-
er de
-
pressurization.
4)
Empty the contents of the pressure tank by using the 3
-
way valve at the bottom of the tank outlet.
5)
Return the 3
-
way outlet valve to its normal position and re
-
open the ball valve on the tank
’
s incoming air inlet
port to re
-
pressurize the tank.
6)
Use the control panel to spray the nozzles until all process fluid remaining in the hoses, manifolds and nozzles is
discharged.
7)
De
-
pressurize the tank, open and remove the agitator from the large port on top of the tank. Use this port for
putting your cleaning solution in the tank. Fill the tank with cleaning solution for auto
-
refill into main tank.
8)
Clean the auto
-
refill system (as applicable)
A)
Liquids for cleaning, rinsing, and sanitation can be fed through the auto
-
refill inlet port.
B)
Turn the auto
-
refill switch to the
“
ON
”
position (provide air to the auto
-
refill pump) to begin filling.
C)
When complete, turn the auto
-
refill switch to the
“
OFF
”
position to stop pumping.
D)
Repeat this process with appropriate fluids till the system is thoroughly flushed.
9)
Clean the pressure tank, delivery hose and nozzle assemblies.
A)
Liquids for cleaning, rinsing, and sanitation can be added through the largest port on top of the tank or fed
through the auto
-
refill system.
B)
Manually clean or wipe down the inside of the pressure tank/sensors/dip tubes.
CAUTION: The lining of the jacketed hose is easily damaged; brushes or other tools should never be
used to clean or remove solids from the hose.
C)
Close any ports on the top of the pressure tank and reopen the ball valve on the tank
’
s incoming air inlet port
to re
-
pressurize the tank.
D)
Use the control panel to spray and move cleaning/sanitizing fluids through the hoses, manifolds, and nozzles.
E)
Large volumes of cleaning/sanitizing fluid can be removed from the tank directly through the 3
-
way valve at
the bottom of the tank.
—This should never be done while the tank is under pressure.
—This valve will divert the tank
’
s outlet but isolate any fluid remaining in the hoses, manifolds, and nozzles.
This fluid needs to be flushed through the nozzles under pressure.
10)
The fluids, time to flush, repetitions, etc.
…
are to be determined by the end user to meet your required level of
cleaning and sanitation.
11)
After cleaning and sanitation, return all valves and port covers to their production ready state.
