SECTION SEVEN
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 gasket inspection/replacement. Quartz
Sleeve inspection/retaining nut gasket replacement must be carried out annually, at minimum.
Parts and Required Equipment
• Paper Towels
• Personal Safety Equipment
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 30. For
installation See Page 11.
2. Thread all sensors into their respective ports on the UV vessel.
3.
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.
4.
Inspect all piping connections to the UV Vessel and confirm that valves are in their correct position prior to start-up.
5. With satisfactory piping and valve inspection, operate the UV system. Allow water to flow through the UV Vessel for no
less then fifteen minutes.
6.
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 30-32.
7.
If no leaks were detected you are now ready to install the UV Lamp(s). See Page 17.
