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 replacing the filter housing O-ring every year or
when replacing the 3 pre-filters.
Important!
It is important to change the 3 pre-filters timely, at least every 6-12 months. The
pre-filters protect the stage-4 membrane. If they are not changed timely and
become over-depleted, the membrane life capacity may be reduced and affect
contaminant removal and pure water production rate.
It’s best to use APEC replacement filters. Using “non APEC”and lesser quality filters
may clog up the RO system and damage the membrane.
We recommend that stage 1-3 filter housings be replaced every 5 years.
FILTER CHANGE INSTRUCTIONS
How To Replace Stages 1, 2, 3 Pre-Filters:
1)
Turn OFF
cold water supply to RO system. Turn OFF tank ball-valve. Turn on the RO faucet lever to
relieve the built-up pressure inside the RO system. This will make opening the housings easier.
2)
Open housing:
Have the RO 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 RO down on
the floor to get a better leverage. If the housing is too tight, use a hammer and gently tap on the wrench
handle to help turn the wrench. See
