1. Introduction
1.1. System Overview
Lync WQ-AS is a complete, fully engineered multi-barrier, packaged system that optimizes your
system’s water quality by integrating scale prevention, sediment filtration and UV disinfection.
Lync WQ-AS is factory pre-assembled to minimize installation time and labor. Standard
components of this system are:
•Lync AquaSolve scale prevention system (LM8414TM-COM) includes mineral tank, scale
prevention media, internal distributor system, stainless steel head component. AquaSolve
provides protection from scale formation on internal plumbing surfaces. AquaSolve®
prevents scale by transforming the normal dissolved hardness minerals into undissolved
crystal microparticles. These crystals stay suspended in the water and have a greatly
reduced ability to react and attach to surfaces like dissolved hardness does.
The LM8414TM-COM is certified through WQA against NSF/ANSI/CAN Standard
61, CSAB483.1, and to NSF/ANSI 372 for Lead Free compliance.
•Lync cartridge filtration system includes filter housing (LCH-150) and a replaceable filter
cartridge (LBC-150-P5). Lync filter cartridge is a 5 micron filter with a housing that is
made of rugged, glass-reinforced polypropylene, so it will not chip, rust or dent. Because
all wetted surfaces are non-metallic, they are ideal when chemical compatibility is an
issue and for sea water applications.
LCH-150 is certified through NSF to NSF/ANSI/CAN 61.
•Lync UV Disinfection System (LD050AGAA) includes reactor chamber(s), UV lamp(s),
quartz sleeve(s), and system controller. Disinfection of water with Lync UV is a simple,
rapid physical process. When contaminated water is exposed to Lync UV 254 nanometer
UV light, the UV light penetrates the cell walls of microorganisms and disrupts their
genetic deoxyribonucleic acid (DNA) material. This quickly inactivates microorganisms by
destroying their ability to replicate and infect
Lync UV (LD050AGAA) is certified by the Water Quality Association (WQA) to
NSF/ANSI Standard 372 for lead free compliance.

WARNINGS!
•Not for use on closed loop systems.
•Do not let the system freeze. Damage to the tank may result.
•Place the WQAS skid on level surface. Because the system operates in an up-flow,
fluidized bed mode, having a level surface is more important than with a softener or
media filter.
•A bypass valve should be installed before and after the skid to facilitate installation and
service.
•Observe all local plumbing and building codes when installing the system.
•Do not apply any other anti-scalants before or after WQAS skid.

Lync WQ-AS

•The addition of soaps, chemicals, or cleaners, before or after AquaSolve treatment, may
reverse its anti-scale treatment effects and/or create water with a heavy residue or
spotting potential. Any adverse conditions caused by the addition of soaps, chemicals, or
cleaners are the sole responsibility of the end user.
•AquaSolve is not a water softener and does not soften the water. Water treatment
chemistry requires to be compatible with water quality requirements outlined in the
specifications table.
Spotting may occur on external plumbing surfaces. AquaSolve media systems perform best in
single pass potable water applications with NO additional chemical additives. Depending on
hardness, soft scale spotting may occur. Soft scale spots in most cases can be easily wiped
down with a damp cloth and will not form hard scale deposits. A Point of Use (POU) Water
Softener should be used on mandatory spot-free applications (e.g. glass stemware, dishware).
Water known to have heavy loads of dirt and debris may require pre-filtration prior to WQAS
skid. AquaSolve technology is effective at controlling lime-scale formation inside the plumbing
system at influent hardness levels up to 75 grains per gallon (1282 mg/l) of calcium carbonate.
Due to variances in water chemistry, 30 grains per gallon is a recommended hardness
maximum due to potential aesthetic issues related to soft scale residue formation outside of the
plumbing system. Testing should be performed to determine proper application where hardness
levels exceed 30 grains per gallon.
Just as with conventional water softening media, AquaSolve media needs to be protected from
excess levels of certain metals that can easily coat the active surface, reducing its effectiveness
over time. Public water supplies rarely, if ever, present a problem, but if the water supply is from
a private well, confirm that the levels of iron (Fe) and manganese (Mn) are less than 0.3 mg/L
and 0.05 mg/L, respectively.
Pursuant to the EPA drinking water standards, the copper concentration permitted is up to 1.3
ppm. Typically originating from new copper plumbing, high levels of copper can foul AquaSolve
media. For applications with copper concentration greater than 1.3 ppm, please consult Lync
Technical Service. To further minimize any problem with excess copper, avoid applying
excessive flux on the inner surfaces of the pipe and use a low-corrosivity water soluble flux
listed under the ASTM B813 standard.
AquaSolve media does not reduce silica scaling. While silica tends to have a less significant
effect on scale formation than other minerals, it can act as a binder that makes water spots and
scale residue outside the plumbing system difficult to remove. This 20 ppm limitation is for
aesthetic purposes. All other contaminants must meet the requirements of the USEPA Safe
Drinking Water Act. Specific Mineral and Metal MCL’s, identified in Lync published Feed Water
Chemistry Requirements, supersedes the USEPA SDWA.
Exceeding maximum flow can reduce effectiveness and void warranty. Pressure drop at peak
flow rate is less than 28 psi (pressure drop reading taken with inlet and outlet gauges installed
at a common elevation and 80 degree feed water).
