CLEANING, SANITIZING, AND CARTRIDGE REPLACEMENT PROCEDURE
1. Mix mild cleaning solution of dish soap and clean
potable water in plastic bowl.
2. Empty storage tank and relieve system pressure.
Verify tank valve is open. Close feed water supply
valve and open product water faucet.
Icemaker
: Transfer ice cubes from bin/tray to clean
freezer container for storage until procedure is done.
3. CAUTION: Use air hand pump to avoid damaging
tank. Verify product water valve is open before
proceeding.
Check product water storage tank air pre-charge using
a low-pressure gauge (e.g. 0 -15 or 0 – 30 psi). Air
valve is located on tank base. Pre-charge should be 55
kPa (8 psig) with tank empty and tank valve open.
4. CAUTION: Do not attempt to remove filter housings
until water flow stops. This reduces pressure inside
the system so housings may safely be removed.
CAUTION: Additional point-of-use devices (i.e.,
icemakers) may use filters along their supply line.
Remove any filter or treatment device installed
between module and device before proceeding.
Remove each filter/membrane housing by turning it
counter-clockwise. Remove each filter cartridge as its
housing is removed. Discard filters.
IF MEMBRANE IS PERFORMING SATISFACTORILY:
Proceed to Step 5.
IF MEMBRANE IS DEPLETED OR FOULED:
Discard it and go to Step 7.
5. 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.
6. Place membrane into clean plastic bag, close bag.
7. Remove filter/membrane housing "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.
8. CAUTION: Do not get Smartap
®
Water Quality
Monitor electronics, wiring, or connectors wet.
Clean filter housings and manifold ports, inside and
outside, with washcloth and cleaning solution. Do not
use abrasive materials.
9. Rinse manifold/housings with clean potable water.
10. Inspect manifold and filter housing "O" ring groove
area for damage (i.e., nicks or scratches). Replace
damaged components.
11. Place a small amount of "O" ring lubricant over
surface of filter/membrane housing "O" ring. Install
"O" ring into filter housing groove.
TO SANITIZE THE SYSTEM: Complete Steps 12-34.
TO INSTALL FILTERS: Complete Steps 19-34.
WARNING: WEAR SAFETY GLASSES WHILE
PERFORMING THIS PROCEDURE.
READ "WARNINGS" INFORMATION ON BLEACH
CONTAINER BEFORE USING CONTENTS.
HANDLE SANITIZING SOLUTION CAREFULLY. AVOID
CONTACT WITH UNPROTECTED AREAS.
12. 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 1.5 ml (1/3 teaspoon) of
household bleach and 3.8 L (1 gallon) of clean,
potable water in the bucket. Mix solution well.
13. CAUTION: Tighten filter housings by hand only. Do
not use tools as they will over-tighten and damage
housings. Take care not to cut or pinch o-rings.
Add 236 ml (one cup or 8 oz.) of sanitizing solution to
each filter housing and install them onto the manifold
(do not install filters or membrane at this time).
Tighten each filter housing by hand only.
14. Slowly open source water supply valve.
15. Open product water faucet. Close faucet as soon as
water begins to flow from spout.
16. Wait 5 minutes, then close source water supply valve.
17. Wait 25 minutes, then open product water faucet and
let water flow to drain.
18. CAUTION: Do not attempt to remove filter housings
until water flow stops. This reduces pressure inside
the system so housings may be removed safely.
Remove filter housings and dispose of water. Rinse
filter housings and manifold ports thoroughly with
clean potable water.
