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).
To properly maintain your APEC drinking water system,
please use only genuine APEC Water replacement filters at
www.freedrinkingwater.com/filters
Stages 1, 2, 3 Pre-Filters: Replace every 12 months.
(FILTER-SET) (Private well water source: may need to replace pre-filters sooner than
12 months due to heavy sediments and other particles.)
Stage-4 Membrane: City Water: Replace every 3-5 years depending on input
(MEM-90)
use MEM-45 for pump models water quality, water usage, and prefilter change maintenance
Private Well Water: Replace every 2-3 years depending on
well water quality, and prefilter change maintenance.
Stage-5 Carbon Filter: Replace every 3-5 years:
It’s best to replace this filter when
(5-TCR-QC) replacing the stage-4 membrane.
Filter Housing O-rings: We recommend that the filter housings O ring be replaced
every 3-5 years.
Important! It is important to change the 3 pre-filters timely, at least every 12 months.
The pre-filters protect the stage-4 membrane. If they are not changed
timely and become over-depleted, the membrane will be damaged and the
RO system will be contaminated.
It’s best to use APEC replacement filters. Using “non APEC” and lesser qual-
ity filters may clog up the RO system and damage the membrane.
We recommend that the plastic filter housings be replaced periodically: every
5 years for the clear housing and opaque housing.
FILTER CHANGE INSTRUCTIONS
How To Replace Stages 1, 2, 3 Pre-Filters:
1) Turn OFF cold water supply to RO system. Turn OFF tank’s ball-valve. Turn ON the RO faucet
briefly to relief the built-up pressure inside the RO system. This will make opening the housings
easier.
