Maintenance
Obtaining Water Samples
Vast majority of unsatisfactory Post-UV Test results
are directly related to the improper sample-taking
techniques. Although several commercial sample
collection apparatuses are available, the proper
manufacturer’s sample procedures must be followed.
NOTE ! Sea Recovery recommends a
valve with a discharge orifice not to
exceed ¼” (6mm).
Sampling Procedure
Use sterile sample bottles obtained from reliable
laboratory that has been autoclaved and kept in plastic
bag for this procedure.
1.
Use temporary tube to direct water from UV unit to
container or drainage.
2. Pressurize the UV unit and flush unit with sample
valve fully opened for 3.5 minutes. After flushing
for 3.5 minutes, reduce valve opening to 50% and
flush for 3 minutes.
3. Open the sample bottle and keep the inside of the
cap facing down.
4. Fill the sample bottle and avoid breathing directly
into the bottle or touching the inside of the bottle,
cap, or neck.
5. Immediately cover and secure the cap after filling
the sample bottle.
6. Label the sample bottle and place in a clean
plastic bag.
7. Take sample bottle to the laboratory for plating as
soon as possible.
NOTE
! Sample processing must
begin within 3 hours after sample
collection and must comply with
accepted standard methods.
8. Wash the Quartz Sleeve with mild soapy water and
rinse in clean hot water.
If dirt remains after rinsing, the quartz sleeve should be
replaced. Contact your local CSR to order a replacement.
NOTE ! Failure to perform quartz sleeve
maintenance may reduce the efficiency of
the UV light to adequately treat water in
the treatment chamber.
Checking for Leaks
Visual inspect the UV unit exterior for signs of leakage.
The cause of any leakage must be located and repaired.
If a leakage is detected, perform the following.
1.
Shut off all electrical power. Shut off the source
of power at the main panel breaker and use
appropriate tag-out procedures to prevent
accidental power-up.
2. Depressurize the UV unit.
3. Remove ballast box cover and remove the
rubber boot.
4. Locate which end of the quartz sleeve is leaking.
Repairing Leaks
If both ends of the quartz sleeve are leaking, perform the
following on both ends.
1.
Use a channel lock to loosen and remove the
compression nut.
2. Remove the quartz sleeve O-ring without pulling
the quartz sleeve out.
3. Lubricate the quartz sleeve tip with clean water
and place new O-ring. Ensure the O-ring has all-
round contact with the cylinder pass-thru.
4. Replace and tighten the compression nut.
5. Refill the treatment chamber and verify a leak-
free condition.
Measuring Performance
Every UV unit must be tested periodically to verify its
efficiency. Regardless of the intended application or any
optional equipment provided with the UV unit, the most
accurate procedure is the Post-UV Analysis. The Post-UV
Test must be performed in accordance with standard
testing methods.
Verifying Lamp Operation
The UV lamp is “ON” when the blue light is emitting thru
the viewport.
