Ultraviolet System Installation
I. Thimble (Quartz Tube) Installation
Due to the fragile nature of the thimble, care must be taken when handling and installing the thimble and lamp. The
below steps are for horizontal installations.
1.
Remove the knurled nuts from either end of the UV chamber (shown below).
2.
Wearing clean gloves or handling with a micro-fibre cloth, remove the thimble from the
packaging and check for any marks or blemishes. Insert the glass thimble into the
chamber from the top (see picture right). DO NOT DROP THE THIMBLE INSIDE THE
CHAMBER AS IT WILL SHATTER.
3.
Allow equal parts of the thimble to be exposed from each end of the chamber and slide
the O-Rings over each end of the glass (shown below). Be careful not to drop the glass
at this point. Once the O-rings are seated, this will assist in holding the glass in place. It
is recommended to put something soft underneath the system just in case the glass
does slip through, as this it may help prevent the glass from breaking if dropped.
