Disinfection Procedure - Pentair UV MAX PUV-7 Owner's Manual

5. Install the UV lamp. Refer to
6. When all plumbing connections are complete, slowly turn on the water supply and check for leaks. The most likely
cause of leaks is from the O-ring seal. In case of a leak, shut water off, drain cell, remove the retaining nut, wipe the O-
ring and threads. Clean and re-install.
7. Once it is determined that there are no leaks, plug the system into the ground fault interrupter and check controller to
ensure the system is operating properly. The controller should illuminate without any alarms.
Note: DO NOT look directly at the glowing UV lamp.
8. Allow the water to run for a few minutes to clear any air or dust that may be in the chamber.
Note: When there is no flow, the water in the cell will become warm, as the UV lamp is always on. To remedy this, run a
cold water tap anywhere in the house for a minute to flush out the warm water.

3.2 Disinfection Procedure

UV disinfection is a physical disinfection process and does not add any potentially harmful chemicals to the water. As UV
does not provide a disinfection residual, it is imperative that the entire distribution system located after the UV be chemically
disinfected to ensure that the plumbing system is free from any bacteriological contaminants. The disinfection process must
be performed immediately after the UV unit is installed and repeated thereafter whenever the UV is shut down for service,
without power, or inoperative for any reason. The procedure for sanitizing the plumbing system is readily accomplished as
follows:
1
• Ensure the controller is
plugged in for entire
disinfection process.
