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.
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.
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.
