6 Month System Maintenance
For filters or replacement parts, contact Multipure at 800.622.9208 or at www.multipure.com
Items 1 Ten inch sediment filter (CBC110)
Needed 2 Ten inch carbon prefilters (CBC112)
1 Bucket to catch water from filter housings
1 Hand tool shipped with the system or wrench to loosen filter housings.
NOTE: Keep RO Module in an upright position while replacing housing bottom in order
to keep O-rings properly seated.
Step 1 Turn off incoming water supply to the RO at needle on adapta valve.
Step 2 Turn off the valve at the RO tank by turning 1/4 turn.
Step 3 For more leverage, leave RO module attached to wall of cabinet. If you
are unable to access the module, you may remove it to change filters.
Starting with the closest housing, remove the housing bottom, using the
hand tool to loosen, and empty water, then discard filters. Continue on
to the 2nd and 3rd housings.
Step 4 Clean all filter housings with a mild soap solution and rinse with water.
Check O-rings and lubricate with water soluble lubricant. Water based
lubricants can be used, but petroleum based lubricants (such as
Vaseline) must not be used.
Step 5 The sediment filter has a cloth-like appearance. It must be in the
FIRST housing on the left (where the water inlet connects).
Step 6 Carbon block prefilters have a mesh covering and a white rubber gasket
on each end. Insert the carbon prefilter with gasket facing up. Be
sure to seat the black O-ring properly in the housing bottom.
Step 7 Repeat this step for the third housing.
Step 8 Discard used filters in your normal refuse.
