ESSENCE RO SYSTEM MAINTENANCE SCHEDULE
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
2-4 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
.
(UVBULB-SS 4 Pin)
Stage-6 Carbon Filter:
Replace every
2-4 years
.
(FI-ES-TCR-QC) It’s best to replace this filter when replacing the stage-4 membrane.
Stage-7 pH
Remineralizer Filter:
Replace every
6-12 months
.
(FI-PHPLUS-QC)
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 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 the plastic 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.
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).
