1. INTRODUCTION
1.1. System Overview
Lync WQ-UV is a complete, fully engineered water quality optimization solution that features
sediment filtration and UV disinfection. Lync WQ-UV is factory pre-assembled to minimize
installation time and labor. Standard components of this system are:
•Lync Cartridge Filtration System includes filter housing (LCH-150) and a replaceable filter
cartridge. Lync Cartridge Filter (LCB-150-P5) 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.
•Lync UV Disinfection System (LD050AGAA) includes reactor chamber(s), UV lamp(s),
quartz sleeve(s), UV sensor, 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.
NOTES:
Lync UV complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
Lync UV complies with Industry Canada license-exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this device may not cause interference, and (2)
this device must accept any interference, including interference that may cause undesired
operation of the device.
Any changes or modifications of this product not approved by the manufacturer could void
the user’s authority to operate the equipment.
Lync UV complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
LCH-150 is certified by NSF to NSF/ANSI/CAN-61
Lync UV (LD050AGAA) is certified by the Water Quality
Association (WQA) to NSF/ANSI Standard 372 for lead free.

Under Industry Canada regulations, this radio transmitter may only operate using an antenna
of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To
reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotopically radiated power (e.i.r.p.) is not more than that
necessary for successful communication.
Lync UV controller is certified by the Federal Communications Commission (FCC) listed
under identification number
FCC ID: 2AFJT-SMARTSTREAM and Industry Canada (IC) listed under IC: 20623-
SMARTSTREAM.
WARNING!
Lync WQ-UV contains a UV-C emitter (UV lamp). Unintended use of the appliance or
damage to the housing may result in the escape of dangerous UV-C radiation. UV-C
radiation may, even in little doses, cause harm to the eyes and skin. Appliances that are
obviously damaged must not be operated. Do not operate the UV-C emitter when it is
removed from the appliance enclosure. The appliance must be disconnected from the power
supply before replacing the UV-C emitter. DO NOT look directly at the UV-C emitter while it is
ON. Permanent serious eye injury could occur.
WARNING!
This appliance can be used by people aged from 18 years and above and persons with
reduced physical, sensory or mental capabilities or lack of experience and knowledge if they
have been given supervision or instruction concerning use of the appliance in a safe way and
understand the hazards involved. Children shall not play with the appliance. Cleaning and
user maintenance shall not be made by children.
Lync UV systems are engineered with the highest quality components. If at any time a
component needs to be replaced, use only parts recommended and supplied by Lync.
DO NOT add components to or remove components from this system. The UV lamp is rated for
9000 hours under normal operating conditions and should be replaced annually to keep the UV
intensity at the highest possible output. Quartz sleeves should be cleaned as needed or
replaced as needed to guarantee the highest possible UV transmittance into the water. Use only
Lync supplied UV lamps and quartz sleeves. Failure to do so may result in system failure and
will void all warranty.
DO NOT use this system in a manner that it is not intended for. This purifier is only for use in
water applications where the feed water, installation environment and installation method meets
the requirements within this manual. The system must be properly sized.
DO NOT exceed the rated flow rate capacity of the system. Flow controllers are available from
Lync to ensure system's rated flow is not exceeded. Follow all product safety labeling. DO NOT
let the system freeze. System damage may result. Install the system on a flat, and level surface.

•Additional pretreatment may be necessary so that the feedwater conforms to the Feed
Water Specifications.
•The skid can be bolted down to the floor, if required.
3.3. Plumbing and UV Connections
It is the responsibility of the end user to ensure that the installation is done according to local
codes and regulations. 2” slip-on PVC flanges in inlet and outlet provides the options for both
flange and slip connections.
1. Turn off water heater(s).
2. Turn off the main water supply valve to the pipe the system will be installed in.
3. Relieve pressure within plumbing system by opening then closing both the hot and cold
sides of a faucet until water ceases to dispense from faucet.
4. If equipped with isolation valves, isolate the water heater(s) by closing its inlet and outlet
valves.
5. Connect the feed water line to the inlet side of the skid. If no isolation valve exists, it is
recommended to install an isolation valve located within 10 feet of the system.
6. Connect the outlet of the skid to treated water line plumbing. If no isolation valve exists, it
is recommended to install an isolation valve within 10 feet of the system.
