Step 9:
You can now gently remove the quartz sleeve from its packaging being VERY careful not
to touch the length with your hands. The use of cotton gloves (not included) is recommended for
this procedure as oils from our hands can leave residue on the sleeve and lamp which can ultimately
block the UV light from getting to the water. In the package, you will find a lubricated o- ring. Place the o-
ring over the open-end of the sleeve as shown in Figure 4.

Step 10:
Carefully slide the sleeve into the reactor until you can feel it hit the opposite end of the
reactor. Slightly push the sleeve in to feel it lock into the spring inside the reactor. Ensure that the o-ring
is butted up against the reactor. Assemble the provided gland nut onto the threaded end of the reactor
and tighten. The gland nut has a positive stop to avoid over-tightening, hand tighten ONLY. Install the
provided stainless steel compression spring inside the quartz sleeve. This spring simply sits in the bottom
of the quartz sleeve and 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 11: (Applies only if you have a UV sensor¼ USWATER6.0)
The UV sensor for the system is
packaged in a separate plastic bag. Carefully remove the sensor from its packaging and insert the
sensor into the UV sensor port (remove the protective cap on the UV reactor first). The sensor can only go
in one way. Ensure that the flat portion of the UV sensor matches up with the half metal lip on the sensor
port (flat portion should face the lamp connection end) (see Figure 5.). Ensure that the sensor is fully
seated in the sensor port and then tighten (turning clockwise) the sensor nut.
PLEASE NOTE:
DO NOT over tighten the nut as this could damage the Teflon sensor body. Plug the
male connector into the IEP port located on the right side of the controller, Figure 6, (make sure the con-
troller is not plugged in as the sensor MUST be attached before power is applied to the controller.)
