A CLEAN WORK AREA AND EQUIPMENT ARE ESSENTIAL TO PROPERLY CLEAN AND/OR DISINFECT THE SYSTEM
(i.e., CLEAN HANDS, TOOLS, WORK SURFACE, AND CONTAINERS)

Rubber Gloves, Sanitary
Wash Cloth, Clean and Lint-Free
Liquid Dish Soap

1. Mix mild cleaning solution of dish soap and clean
potable water in plastic bowl.
2. Close inlet and outlet water supply valves and
relieve system pressure.
3.
CAUTION:
Do not attempt to remove sumps until
water flow stops. This reduces pressure inside
the system so sumps may safely be removed.
Remove each sump by turning it counter-clockwise.
Remove each filter cartridge as its sump is removed.
Discard filters.
IF MEMBRANE IS PERFORMING SATISFACTORILY:
Go to Step 4.
IF MEMBRANE IS DEPLETED OR FOULED:
Discard it and go to Step 11.
4.
CAUTION:
Use sanitary rubber gloves for this
procedure to avoid contaminating sanitizing solution,
filters, or membrane. Wear gloves whenever
cleaning/ sanitizing system components or handling
new filter/membrane cartridges.
Clean membrane outer wrap with washcloth and
cleaning solution. Do not immerse membrane in
solution. Do not scrub membrane wrap with
abrasive cleaners. Rinse membrane well with clean
potable water.
5. Place membrane into clean plastic bag, close bag.
6. Remove sump "O" rings and wash them with
cleaning solution. Rinse them well with clean
potable water. Inspect them for damage
(i.e., nicks, scratches). Replace damaged "O" rings.
7. Clean filter sumps and manifold ports, inside and
outside, with washcloth and cleaning solution. Do
not use abrasive materials.
8. Rinse manifold and sumps with clean potable water.
9. Inspect manifold and sump "O" ring groove area for
damage (i.e., nicks or scratches). Replace damaged
components.
WARNING: USE FDA APPROVED SILICONE
LUBRICANT ON “O” RINGS. DO NOT USE
PETROLEUM-BASED LUBRICANTS.
10. Place a small amount of "O" ring lubricant over
surface of sump "O" ring. Install "O" ring into sump
groove.
TO SANITIZE THE SYSTEM: Complete Steps 11-26.
TO INSTALL FILTERS: Complete Steps 18-26.
WARNING:
WEAR SAFETY GLASSES WHILE
PERFORMING THIS PROCEDURE.
WARNING: READ "WARNINGS" INFORMATION ON
BLEACH CONTAINER BEFORE USING CONTENTS.
HANDLE SANITIZING SOLUTION CAREFULLY.
AVOID CONTACT WITH UNPROTECTED AREAS.
11.
CAUTION:
Excessive concentrations of bleach will
damage plastic and rubber components. Rinse all
parts that contact bleach thoroughly with clean
potable
water.
Mix sanitizing solution of 1/3 teaspoon (1.5 ml) of
household bleach and 1 gallon (3.8 L) of clean,
potable water in the bucket. Mix solution well.
12.
CAUTION:
Tighten sumps by hand only. Do not
use tools as they will over-tighten and damage
sumps. Take care not to cut or pinch “O” rings.
Add 8 oz. (236 ml) of sanitizing solution to each
sump and install them onto the manifold (do not
install filters or membrane at this time). Tighten
each sump by hand only.
