LYNC UV-H
SECTION 5: OPERATING INSTRUCTIONS

Lync by Watts recommends sanitizing the household or facility plumbing by adding 50 ppm
chlorine from bleach for 12 hours and then flushing. This can be achieved by:
1. Shutdown and unplug the unit.
2. Shut off the water supply and relieve the water pressure by opening a tap.
3. Remove the filter from its housing and fill the housing with bleach
4. Re-mount the housing (but not the filter) and plug in the unit to turn it on.
5. Once unit is operating, turn on the water supply and have the water flow to all taps (hot and cold),
toilets, the washing machine and other water-using appliances
– the bleach must fill every inch of
plumbing. The Dose Alarm may arise due to low UVT after the introduction of bleach. If this occurs,
use the manual override on the optional solenoid valve to keep valve open during procedure. Return
override to auto position afterward.
6. When you detect the odor of chlorine at each spot, turn off the water and let the bleach remain in
the lines for at least 12 hours. Turn off UV unit during this time.
CAUTION! Do not allow corrosive chemicals to remain in the unit for more than 12 hours
– Do not operate unit
during this time period as heating the water will increase corrosive nature of chemicals.
7. After the waiting period is over, plug in the unit. Once stable, flush every line for at least five
minutes or until the odor of chlorine is gone. See local regulations for proper disposal of chlorine
residual, especially in the case of discharge into a septic system.
8. Now that the disinfection procedure is complete you will need to return the filter to its housing.
Shut off the water supply, relieve water pressure by opening a tap, and return the filter to the
housing. Allow a few days after a disinfection procedure before getting a sample since residual
chlorine may affect the results.
9. Have the water tested by a local recognized testing agency prior to any water consumption. Lync
partners with water testing organizations in select locations throughout North America. Contact
Lync for potential water testing partners: (800) 433-5654 (ext. 3). The testing should be performed
on a regular basis as required by local regulations.
5.7 Automatic Quartz Sleeve Cleaning Device
The self-cleaning feature of the UV-H system involves a wiper turning inside the quartz sleeve. The
wiper operates soon after power up of the lamps and then every 4 hours it will cycle for 5 minutes. The
wiper can be enabled anytime in the Advanced Settings menu, item 2.2.1.2. The LED will flash quickly
during a wiper cycle.
5.8 Built in Purge Valve
The UV-H contains a flushing or purge valve that cycles water through the unit during long periods of no
water usage. The unit monitors water usage by measuring the rise in water temperature within the
treatment chamber. During periods of no water flow, the purge valve on the small units can expel 1
gallon (4 liters) of water every 60-90 minutes; the largest unit can expel up to 4 gallons (15 liters). If the
largest unit fails to purge and the water temperature exceeds 113
°
F (45
°
C), the unit will shut down to
prevent overheating.
