INSTALLATION REMINDER

1. Make sure the voltage and phase of the system you order. never use wrong setting.
   2. Check the pure/concentration water are piped correctly.
   3. The power line core should be large enough (not less than 3.5 mm)
   4. Be aware not to let brine flow through the system while the system is backwashing.
   5. Make sure the system’s Inlet/Outlet is connected correctly.
   6. Measure feed water pressure with a water pressure gauge. Feed water pressure is
   preferably to be 35 psi and the minimum is 26 psi. If lower than 26 psi, it should install a
   booster pump at the feed water location.
   7. Check prefilters every week to make sure the water supply

REPLACEMENT OF CARTRIDGES & MAINTENANCE

The replacement of filter cartridges depends greatly on the quality and condition of the water
in the local area where the reverse osmosis system is placed. Please follow the instructions below
to ensure good performance of the system.
1. Sediment filters: It is most recommended to replace the filter cartridges every three
months.
2. Carbon prefilter: Replacement depends on the water usage and chlorine concentration in
your area. As a general rule, if the chlorine concentration is less than 0.22 ppm, use the
the following equation to calculate the replacement frequency (RF):
6000 (gallons) x0.15
usage per person per day (gallons/day)x =RF
number of people in the household
3. In-line carbon post filter cartridge: Replace every 2,500 gallons.
4. Membrane element: Replace when a persistent high TDS value exists. Membrane fouled,
hydrolyzed, ruptured, or attached by bacteria.
5. Feed water tubing: Replace once every year to maintain a clean water supply
