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 con-
tainer 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 re-
moved. 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 dam-
aged “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 compo-
nents.
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 plas-
tic 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.
