YOUR MEMBRANES HAVE BEEN SHIPPED WITH AN ANTI-BACTERIAL PRESERVATIVE.
OPERATE THE SYSTEM FOR 1 HOUR AT DESIGN SETTINGS BEFORE BRINGING THE
SYSTEM ONLINE TO ASSURE MEMBRANE HAS BEEN COMPLETELY FLUSHED. DO
NOT USE WATER PRODUCED DURING THIS RUN-IN PERIOD.
A Note on Recovery Rates
Your Vectapure™ RSXII Lite is designed to operate at a recovery rate (percentage of product
water to total water used) at maximum of 50% for feed water of <1000 TDS and 33% for feed
water with TDS ranging from 1000 to 2000.
DO NOT ATTEMPT TO OPERATE THE SYSTEM AT
HIGHER RECOVERY RATES, AS THIS WILL CAUSE PREMATURE MEMBRANE FAILURE OR
INTERNAL SCALING AND EQUIPMENT FAILURE.
Section 5: System Maintenance
Changing Pre-filter Cartridges
The pre-filter cartridges should be changed, as a rule of thumb, every month, biweekly in heavy
use applications. It is critical that this be done to ensure that pre-treatment cartridges allow
necessary flow and that suspended particulate is removed from the feed water.
To change the cartridges, begin by closing the water supply to the unit. Repeat Step 7 (1) from the
installation instructions above. Thoroughly flush and clean the filter housings while they are
disassembled.
If a carbon block (CBC) cartridge is used for the pre-filter housing and is the only pre-filter for
chlorine, make sure that the cartridge is changed in accordance with the manufacturer’s
specification for chlorine capacity. Chronic exposure to chlorine will damage the membrane thin
film and degrade system performance.
