CLEANING, SANITIZING, AND CARTRIDGE REPLACEMENT PROCEDURE
1. Mix a mild cleaning solution of dish soap and clean
potable water in the plastic bowl.
2. Shut feed water supply valve and open product water
faucet to relieve system pressure.
NOTE:
Do not attempt to remove filter housings until water
flow stops. This reduces pressure inside the
system so housings may be safely removed.
3. Remove each filter housing by turning it counter-
clockwise. Remove each filter cartridge as its housing
is removed. Discard filters.
Icemaker:
Transfer ice cubes from bin/tray to clean
freezer container for storage until procedure is done.
NOTE:
Use sanitary rubber gloves for this procedure to
avoid contaminating sanitizing solution or filters.
Wear gloves whenever cleaning/ sanitizing system
components or handling new filter cartridges.
4. Remove filter housing "O" rings and wash them with
cleaning solution. Rinse them well with clean potable
water. Inspect the "O" rings for damage (i.e., nicks or
scratches). Replace damaged "O" rings.
NOTE:
Use caution when cleaning module. Do not get the
Smartap
®
Flow Monitor electronics, wiring, or
connectors wet.
5. Clean filter housings and manifold ports, inside and
outside with washcloth and cleaning solution. Do not
use abrasive materials.
6. Rinse housings/manifold with clean potable water.
7. Inspect manifold and filter housing "O" ring groove
area for damage (i.e., nicks or scratches). Replace
damaged components.
8. Place a small amount of "O" ring lubricant over the
surface of the filter housing "O" ring. Install the "O" ring
into the filter housing groove.
TO SANITIZE SYSTEM:
Complete Steps 9-29.
TO INSTALL FILTERS:
Complete Steps 17-29.
CAUTION:
WEAR SAFETY GLASSES WHILE
PERFORMING THIS PROCEDURE.
CAUTION:
EXCESSIVE CONCENTRATIONS OF
BLEACH WILL DAMAGE PLASTIC AND
RUBBER COMPONENTS. Rinse all parts
that contact bleach thoroughly with clean
potable
water.
CAUTION:
Read the "WARNINGS" on the bleach
container before using.
CAUTION:
Handle sanitizing solution carefully. Avoid
contact with unprotected areas.
9. 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 the solution well.
10. Add 236 ml (one cup or 8 oz.) of sanitizing solution to
each of the filter housings and install them onto the
manifold (do not install filters at this time). Tighten
each filter housing by hand only.
NOTE:
TIGHTEN FILTER HOUSINGS BY HAND
ONLY. Do not use tools as they will over-
tighten and damage housings.
11. Slowly open the feed water supply valve.
12. Open product water faucet. Keep open for 5 seconds
after water starts coming out.
13. Close the product water faucet.
14. Wait 30 minutes, open product water faucet and let
water flow 5 minutes.
15. After 5 minutes, close feed water supply valve and
allow water to flow until system pressure is relieved.
NOTE:
Do not attempt to remove filter housings until water
flow stops. This reduces pressure inside the
system so housings may be safely removed.
16. Remove the filter housings and dispose of the water.
Rinse housings and manifold ports thoroughly with
clean potable water.
NOTE:
Do not remove protective plastic bag from filters.
Open the top of the bag only enough to expose the
top cap and "O" rings. Place a small amount of
“O” ring lubricant on surface of each “O” ring.
17. Install the filter cartridges. Hold cartridge by its
protective plastic bag and insert the cartridge into the
manifold turning it 1/2 turn as it enters the port (See
Page II, Figure 1 for location of each cartridge).
Slide bag from cartridge and discard. Replace each
filter housing as each cartridge is installed.
NOTE:
TIGHTEN FILTER HOUSINGS BY HAND
ONLY. Do not use tools as they will over-
tighten and damage housings.
