Step 6: Once the system has been plumbed in, gently remove the
quartz sleeve from its packaging being careful not to touch the length
with your hands. The use of cotton gloves is recommended for this
procedure as oils from the hands can leave residue on the sleeve and
lamp which can ultimately block the UV light from getting to the wa-
ter.
Carefully slide the sleeve into the reactor until you can feel it hit the
opposite end of the reactor. Align the sleeve so it centered along the
length of the reactor, then gently push it in to lock it into the inter-
nal centering springs in the far side of the reactor. CAUTION: Pushing
too hard when the sleeve is not aligned can damage the centering
springs. Slide the o-ring onto the sleeve until it is butted up against
the reactor.

Sleeve Installation
Step 7: Hand tighten the provided gland nut over the quartz sleeve onto the threaded end of
the reactor. It has a positive stop to prevent over-tightening. A firm force may be required to fully
tighten the gland nut, but DO NOT USE TOOLS for this step. Insert the provided stainless steel
compression spring into the quartz sleeve. The spring works with the lamp and lamp connector
to create the proper lamp alignment. PLEASE NOTE: DO NOT install a UV lamp inside the quartz
sleeve without the sleeve spring in place.
Step 8: Install the UV sensor (UVDM systems only). Align the flat portion so it faces the gland
nut end and matches up with the half metal lip on the sensor port (see Figure 5). Insert the sen-
sor so it is fully seated and hand tighten the sensor nut.

Step 9: The reactor is now ready for water flow. When all plumbing connections have been
completed, slowly turn on the water supply and check for leaks. Make sure the by-pass valves are
functioning properly and that the water is flowing through the reactor. The most common leak
is from the o-ring not making a proper seal on the reactor. For new installations, review steps 6
and 7. For older systems drain the reactor, remove the o-ring, dry it and reapply silicon grease.
Reinstall the o-ring ensuring that it is properly sealed against the reactor and check again for
leaks.
Step 10: Mount the controller to the wall so it is above or beside the reactor to ensure that no
moisture can deposit on any of the connections (see Figure 1). Always mount the controller verti-
cally. For monitored systems, insert the sensor connector into the IEP port located on the right
side of the controller (Figure 6). For the sensor to be recognized by the controller, the controller
power must be plugged in last. Do not plug the controller power cord in before the last step.
