B. Changing Modules 

THIS RO SYSTEM CONTAINS MODULES WHICH MUST BE REPLACED AT REGULAR INTERVALS TO MAINTAIN PROPER 

PERFORMANCE. USE ONLY FACTORY APPROVED MODULES.

For replacement modules contact the local dealer who installed your system or contact the distributor to find the nearest 

dealer.

All individuals should take adequate precautions when changing the filters, including wearing protective gloves, to maintain 

a sanitary environment handling and changing modules.

The recommended interval for changing the Pre and Post Filter modules is every 6 to 12 months depending on the raw water 

quality (not the RO Membrane). Typical TFC Membrane life expectancy is three years average. Local conditions may dictate 

more frequent changes.

NOTE: If the RO Membrane is to be replaced, see Sec. IV, F.1- 2 for the proper procedure. When 

changing membrane treat as if it is a new install, membranes have a preservative in them.

Use a drip pan to catch any water that may spill when the Filter Modules are removed. Refer to installation views on page 5 

for proper locations.
