FILTER REPLACEMENT
Periodic replacement of the sediment pre-filter and carbon block filter should be accomplished in
accordance with the manufacturer's instructions. Replacement of pre-filter and carbon block
cartridges should be scheduled as necessary with regard to filter size, feed water quality, and water
volume usage. Regular scheduled maintenance of the pre-filter is required to prevent premature
failure of Pure Link system components.
3.2
WATER QUALITY
Periodic water quality testing of the Product Water is recommended every six (6) months at a
minimum. When TDS reduction of system is less than 80% compared to untreated feed water,
Lancer recommends replacement of the Membrane Module(s). Sanitizing procedures should be
followed when necessary to reduce bacteria growth. See Section 1.12 of this Manual.
