SECTION 4: MANDATORY WATER TEST
Mandatory Water Test
Purpose
The Mandatory Water Test identifies a potential quartz
sleeve assembly seal failure. During normal UV system
operation, a quartz sleeve assembly failure can result
in extensive damage to the UV lamp, quartz sleeve and
ballast.
Frequency
The Mandatory Water Test must be performed after
a quartz sleeve/retaining nut O-Ring inspection/
replacement. Quartz Sleeve inspection/retaining nut
O-Ring replacement must be carried out annually, at
minimum.
Parts and Required Equipment
• Paper Towels
• Personal Protective Equipment
WARNING: If a sleeve nut is removed when there
is dynamic water pressure inside the UV system, the
lamp sleeve will eject from the end plate with enough
force to cause personal injury.
General risk due
UV Lamps are fragile and potentially dangerous
if broken. Handle with care.
Procedure
IMPORTANT: Failure to perform a water test could
lead to unsafe conditions and may void your product's
warranties.
1. With the quartz sleeves installed inside the UV
vessel, before installation of the UV lamps, perform
a water test as explained below. For quartz sleeve
removal See Page 18. For installation See Page 10.
2. Place rolled-up paper towels into the Quartz Sleeve
Retaining Nuts. During the water test, the paper
towels may absorb moisture. The presence of any
moisture identifies that a quartz sleeve seal failure
(leak) has occurred.
3. Inspect all piping connections to the UV Vessel and
confirm that valves are in their correct position prior
to start-up.
4. With satisfactory piping and valve inspection,
operate the UV system. Allow water to flow through
the UV Vessel for no less then fifteen minutes.
5. After fifteen minutes of flowing water through the UV
vessel, remove the paper towel from each Quartz
Sleeve Retaining Nut and inspect closely for ANY
sign of moisture. If leaks are detected, shut the
system down and re-install any quartz sleeve with
an inadequate seal. For quartz sleeve removal/
installation See Page 18.
6. If no leaks were detected you are now ready to install
the UV Lamp(s). See Page 14.
