SYSTEM MAINTENANCE
The system requires very little maintenance. Just change the filter cartridges regularly as suggested
below. Keep the system indoors away from extreme heat or cold temperatures, and run the system
within its reasonable output capacity (i.e. allow the system to rest at least a few hours a day).
Stages 1, 2, 3 Filters: Replace every 12 months.
(Private well water source: may need to replace filters sooner than 12 months due to heavy
sediments and other particles.)
Filter Housing O-rings: We recommend that the filter housings O-ring be replaced every 3-5 years
Important!: It’s best to use APEC replacement filters. Using “non APEC” and lesser quality filters
may clog up the system.
We recommend that the stage 1-3 filter housings be replaced every 5 years.

3) Discard 3 used filters, wash housings with mild soap, rinse off. Put 3 new filters into their respec-
tive housings: sediment filter in stage-1, carbon block filters in stages 2 & 3.
4) Close up the housings. Make sure each housing has a black O-ring in the thread groves. Use
wrench to tighten each housing, then use filter wrench to fully tighten each housing. Do not over-
tighten.
5) Remember: Turn ON the cold water supply after finished changing filters!
6) Check for leaks!

FILTER CHANGE INSTRUCTIONS
How To Replace Stages 1, 2, 3 Filters:
1) Turn OFF cold water supply to system. Turn the faucet handle to horizontal position to release
the built-up pressure inside the system. This will make opening the housings easier.
2) Open housing: Have the System standing upright. Slip the plastic wrench onto the 1st housing.
Looking down from a top view, you should open the housing turning clockwise. If necessary, lay
system down on the floor to get a better leverage. If the housing is too tight, use a hammer and
tap on the wrench handle to help turn the wrench. See Fig.10.
After taking the housing off,
take out the dirty filters and put
the 3 new filters in. Remember,
Stage 2 and Stage 3 are the
same carbon filters.
