1.1 : Installation instructions for the Acuva Water Purification Systems:
1. Find an under-counter position for the UV device and the pre-filter to be mounted that
will allow space for the PEX tubing to be connected without needing to bend the tube to
the point where they risk pinching or folding.
2. Mount the Din-Rail (Item not shown in Fig.4) that will hold the UV device with two #10
wood screws and the mounting clips (Item no.3) for the pre-filter into position.
3. To install the ½" PEX-3/8" 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 when cut, and cut the cold-water line with PEX tube cutters to insert
the ½" cold-water line 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 3/8" PEX tubing (Item no.2) that will connect the Tee to
the Pre-Filter (Item no.4), and insert the tube into the 3/8" OD female end of the Tee,
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 3/8" OD – ¼" MNPT Adapters (Item no.5)
with Teflon Tape and screw these adapters into the 2 female ends of the pre-filter,
connect the 3/8" 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.
6. To install the UV device (Item no.7), wrap Teflon Tape onto the threads of the 3/8"OD-
3/8"MNPT Adapters (Item no.6) and fasten these adapters into the inlet and outlet female
ends of the UV device.
7. Snap the Pre-Filter to its Clips and mount the UV device to the Din-Rail as seen in Figure
5.
8. Cut a length of 3/8" PEX tubing that will connect the Pre-Filter to the UV device inlet
female adapter with the tubing by pushing the tube into the adapters as far as possible
and pulling slightly to ensure that their seals are secure.
9. Cut a short length of 3/8" tubing and connect to UV device female outlet adapter and
attach the 3/8"OD-¼" Union (Item no.9) to the end of the 3/8" tube.
10. Cut a length of ¼" PEX tubing (Item no.10) that is long enough to connect the 3/8"OD-¼"
Union to the faucet and proceed to the faucet installation.
11. For the Acuva Eco only, install the provided flow restrictor (Item no.11) inline with the ¼"
PEX tubing.
