Appendix: Installation Instructions
UV-LED Device Installation
1. Find an under-counter position for the UV-LED device and pre-filter to
be mounted, allowing space for the PEX tubing to be connected without
needing to bend the tube to the point of pinching or folding.
2. Mount the Din-Rail (Item shown in the “Mounting The Unit” diagram) that
will hold the UV device with two #10 wood screws, and the filter clips
(Item no.3) for the pre-filter with the two remaining screws.
3. To install the ½” PEX-1/4” OD Tee & shutoff valve (Item no.1) to the cold-
water line, assure that the cold-water line is not under pressure, that the
water pump is not powered or that water flow is cut off by an upstream
shutoff valve. Expect some water to drain from the cold-water line and
cut the cold-water line with PEX tube cutters. Insert the ½” cold-water
lines to the ½” female ends of the Tee, push the tubes into the Tee as far
as possible and pull slightly to assure that the seal is secure.
4. Attach a length of the provided 1/4” PEX tubing (Item no.2) that will
connect the Tee to the Pre-Filter (Item no.4), insert the tube into the 1/4”
OD female end of the Tee, and push the tube into the Tee as far as
possible and pull slightly to assure that the seal is secure.
5. To install the Pre-Filter, wrap the threads of the 1/4” OD – ¼” MNPT
Adapters) with Teflon tape and tighten these adapters firmly into the 2
female ends of the pre-filter with plyers or a wrench, connect the 1/4” PEX
tube from the Tee into the inlet side of the pre-filter while making sure
that water will flow in the proper direction as indicated on the filter. Push
the tube into the adapter as far as possible and pull slightly to assure
that the adapter is properly sealed. Install the provided filter clips with #10
screws and snap the Pre-Filter into its clips.
6. To install the UV device (Item no.5), mount the UV device to the din-rail as
seen in the “Mounting the Unit” figure.
7. Cut a length of 1/4” PEX tubing that will connect the pre-filter to the UV
device inlet tube and secure the ¼” itube into the UV device inlet push-
connect fitting as far as possible and pulling slightly to ensure that their
seal is secure.
8. Cut a length of 1/4” PEX tubing that will connect the UV device and the
faucet, install the flow restrictor (Item no.6) at a point on the ¼” PEX tube
that is convenient, and connect the tubing to the desired water faucet or
appliance.
