ESSENCE RO SYSTEM MAINTENANCE SCHEDULE
The system requires very little maintenance. Just change the filter cartridges regularly as suggested below.
Keep the system indoors away from extreme hot or cold temperatures, and run the system within its reason-
able output capacity (i.e. allow the system to rest at least a few hours a day).
To ensure the longevity and integrity of your drinking water system,
please use genuine APEC Water replacement filter at
www.freedrinkingwater.com/parts.htm
Stages 1, 2, 3 Pre-Filters: Replace every 6-12 months.
(FILTER-SET-ES)
(Private well water source: may need to replace pre-filters sooner than
12 months due to heavy sediments and other particles.)
Filter Housing O-rings: We recommend replacing the filter housing O-ring every year or when
replacing the 3 pre-filters.
Stage-4 Membrane: City Water: Replace every 2-3 years depending on input
(MEM-ES-75) water quality, water usage, and pre-filter change maintenance
Private Well Water: Replace every 2 years depending on well water
quality, and pre-filter change maintenance.
Stage-5 UV Light: Replace UV light bulb every 12 months.
(UV-BULB 4 Pin)
Stage-6 Carbon Filter: Replace every 2-3 years.
(FI-ES-TCR-QC) It’s best to replace this filter when replacing the stage-4 membrane.
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-deplet-
ed, 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 quality filters may clog up
the RO system and damage the membrane.
We recommend that the plastic housings to be replaced periodically: Every 5 years for the opaqu
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 ball-valve. Lift up RO faucet lever briefly to
relief 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 #1 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 tap on the wrench handle to
help turn the wrench (See Fig.14 on page 19).
