6. After the lamp has been rotated correctly, allow the 4 pins of the lamp to engage into the socket,
push firmly down on the top of the lamp while holding socket. Do not twist the lamps when they are
inserted. Observe the base of the lamp to confirm the pins are fully seated into the socket. Repeat
for other lamp.
7. Close the UV Chamber and secure door.
8. Record the date of the lamp replacement in your Service Record Sheet.
9.
Plug in the unit. The lamp lifetime counter can be reset in the Settings
menu, item 2.5 (375 days
for LPHO lamps, 500 days for amalgam lamps).
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.
The UV intensity value can be observed to confirm output levels. It
is recommended for new LPHO lamps to be operated initially 3-4 hours as a burn-in to
achieve lamp stability.
7.3 Draining the Unit
Draining is not normally required for routine operation or lamp replacement, but it is necessary to
disassemble the system, to protect against freezing, or to remove poor-quality water.
Tools Needed:
Pipe wrench
1. Shut off the water supply and relieve the pressure.
2. Shutdown and unplug the unit.
3. Place a bucket under the unit to collect the water.
4. Open a tap downstream of the unit to vent.
5. Open the optional drain valve, if installed, and disconnect the flexible hose or piping at the bottom
port to allow the system to drain for a few minutes. Note that the water will not flow backwards
through the optional automatic valve.
6. When draining is complete, close drain valve or reconnect flexible hose or pipe connections.
7. Close any taps that were previously opened.
7.4 Cleaning the Unit
Lync UV-H has an automatic quartz sleeve cleaning device within the systems to virtually eliminate the
disassembly and cleaning of the quartz sleeve - the quartz sleeve will remain clear and transparent as
glass. If a component of the cleaning device fails, such as the wiper motor, or in extreme water cases
with unique water chemistry, the quartz sleeve may become fouled and require manual cleaning. In this
situation the Dose Alarm will arise and alert you to the unsatisfactory conditions. Follow the steps below
to inspect the quartz sleeve and disassemble the unit for cleaning.
7.5 Determining the Need for Cleaning
1. Shutdown and unplug the unit.
2. Open the UV chamber as described in Accessing UV Chamber section.
3. Examine the quartz sleeve both inside and out
– See Figure 7.2. If it is clean, no disassembly is
required and the unit can be closed. Restart the unit by plugging it in.
4.
If the quartz sleeve is dirty on the outside, clean with a clean lint-free cloth and rubbing alcohol.
