Sanitization Steps
STEP 1: TURN OFF WATER SUPPLY - CLOSE INLET SUPPLY ALL THE
WAY
STEP 2: DEPRESSURIZE SYSTEM - OPEN FAUCET SUPPLY UNTIL ALL
WATER IS EMPTIED
Use a clean drip pan or basin to continue to catch any spilled water remaining
in the housings as you remove the membrane and cartridges.
STEP 3: (Refer to Figures 12, 13 and 14) DISCONNECT THE FEED
TUBE FROM THE MEMBRANE HOUSING MODULE. UNSCREW
THE MEMBRANE HOUSING MODULE END CAP AND REMOVE THE
MEMBRANE ELEMENT. PUT THE MEMBRANE ELEMENT ASIDE ON A
CLEAN DISINFECTED SURFACE.
(Unless the membrane element is being replaced at this time, then discard
the old membrane.)
STEP 4: OPEN THE FILTER SUMPS WITH THE SUMP WRENCH
SUPPLIED AND REMOVE THE CARTRIDGES.
STEP 5: CLEAN THE FILTER SUMPS WITH SOAP AND CLEAN WATER.
USE A CLOTH OR SOFT BRUSH AS REQUIRED. CLEAN THE INSIDE OF
THE MEMBRANE HOUSING AS WELL.
(You may need to pay close attention to the O-Ring seals and re-grease them
afterwards with silicone lubricant)
STEP 6: REINSTALL THE FILTER SUMPS (EXCEPT THE 1ST PRE-
FILTER SUMP) AND THE MEMBRANE CAP AND RECONNECT THE
INLET TUBING TO THE MEMBRANE HOUSING CAP.
STEP 7: MIX UP A DISINFECTANT SOLUTION OF 1 TEASPOON OF
5.25% BLEACH IN 1 GALLON OF WATER.
