LYNC UV-H
SECTION 5: OPERATING INSTRUCTIONS

4. When the UV Lamps have started, (lamp ignition for amalgam lamps may take up to 30 seconds) the
unit will wait at 10 - 15 minutes depending on the model to allow the lamps to stabilize before
transitioning into Treating mode. This will occur every time the UV lamps are powered up. During
this warm up, the green LED will flash, the unit will display the countdown to startup, and the
optional shutoff valve will remain closed.
New LPHO lamps may take from a few moments to
several hours to reach full power. Continue to operate the unit until the lamps reach full power
–
this may last 24 hours. It is recommended for new LPHO lamps to be operated initially 3-4 hours
as a burn-in to achieve lamp stability.
When the warm up process is complete, a solid green light
appears and the message
“Unit Treating” will be displayed. The optional solenoid valve will be
allowed to open only if treatment levels are adequate, otherwise it will remain closed. This is the
normal operating mode of the unit.
5. If a power outage occurs, upon return of the power, the unit will start up automatically and perform
a diagnostic check. After a 10-15 minute stabilization period, the unit will begin treating if treatment
levels are adequate, otherwise an alarm will be issued if the unit is not treating.
6. Test wiper motor and purge valve -
see Advanced Settings menu, items 2.7.1.2 and 2.7.1.3.
7. Operator should adjust maximum flow setting if required.
5.4 Flushing Instructions
Flushing the system is required after installation or after any disassembly and cleaning. Flushing may
also be required to remove colored or contaminated water from the unit. Most filters (if installed) also
require flushing prior to use
– follow the manufacturer’s recommendations.
The system may be flushed manually by disassembling the unit and filling and draining the unit by hand
(see In-place Cleaning section). Flushing may also be done while the unit is operating. Plug in the unit
and open a tap closest to the unit and have the water flow for at least 15 minutes.
5.5 Shutting Down of Unit and Seasonal Use
To shut the unit down, initiate the Power Down procedure located as the second item in the Settings
Menu. When this procedure is complete, simply unplug the unit.
The UV-H can operate for extended periods of time without water usage as long as pressurized water is
present to allow for purging. The unit may be shut down in the case of seasonal residences or during a
vacation. If the possibility of freezing exists, the unit and any valves and filters must be drained. (See
Draining the Unit section.)
5.6 Disinfecting the Plumbing
Disinfection of the household or facility plumbing should be performed after the UV-H has been installed
and is operating. This procedure should also be done if the unit is not functioning normally; if a bypass
has been used; or if there has been a high background bacteria count in a water sample. Lync by Watts
has found that disinfecting the plumbing is the best way to treat any potential bacteria or contaminants
in the distribution system prior to system use.
Please note that this procedure is ineffective against protozoa that can be found in surface water
or shallow wells under the influence of surface water. Under these circumstances, it is important
to perform the disinfecting procedure and then operate the UV-H. Lync by Watts has found that this
procedure does not work with sediments or heavy biofilm and encrustations, which must be removed
mechanically.
