CLEANING PROCEDURE
CAUTION:
Clean all parts (except filters and electronic
parts) with the specified cleaning solution and rinse them
with RO product, distilled, or de-ionized water.
NOTE:
Refer to individual System Assembly and
Activation Procedures to identify specific components
matching the descriptions shown in this procedure.
1. Disconnect system from electrical outlet.
2. Mix a mild cleaning solution of dish soap and clean
potable water in the plastic bucket.
3. Close feed water supply valve and open outlet valve
to relieve system pressure.

CAUTION:
Do not attempt to remove sumps until
water
flow stops. This reduces pressure inside the
system so sumps may be safely removed.
Remove each sump. Use sump wrench to remove
stubborn sumps. Remove each filter as its sump is
removed. Discard the filters.
5.
CAUTION:
Use sanitary rubber gloves for this
procedure to avoid contaminating cleaning solution
or filters. Wear gloves whenever cleaning
components or handling new filters.
CAUTION:
If quartz sleeve is removed or twisted,
replace “O” rings.

remove calcium carbonate deposits. Do not use
abrasive materials. Rinse sleeve thoroughly.
Replace any sleeve that is damaged or will not come
completely
clean.
