2.2
: 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 shown in the “Mounting The Unit” diagram) that will hold
the
UV device with two #10 wood screws, and the filter clips (Item no.4) for the pre-filter with
the two remaining screws.
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 and cut the cold-
water line with PEX tube cutters. Insert the ½” cold
-
water lines to the ½” female en
ds 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), insert the tube into the
3/8” 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 3/8” OD –
¼” MNPT Adapters (Item no.3)
with Teflon tape and tighten these adapters firmly into the 2 female ends of the pre-filter
with plyers or a wrench, 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 Adapter and ¼”OD
-
3/8”MNPT Adapter (Item no.6 & 8
), and tighten these
adapters into the inlet and outlet of the UV device as shown in the installation diagram.
7.
Snap the Pre-Filter into its clips and mount the UV device to the din-rail as seen in the
“Mounting the Unit” figure.
8.
Cut a length of 3/8” PEX tu
bing that will connect the pre-filter to the UV device inlet
3/8”OD
-
3/8”MNPT Adapter by pushing the tube into the adapters as far as possible and
pulling slightly to ensure that their seals are secure.
9.a For the Eco
: Cut a length of 1/4” PEX tubing that
will connect the UV device and the faucet,
install the flow restrictor (Item no.10) at a point on the ¼” PEX tube that is convenient,
and proceed to the faucet installation.
9.b For the Arrow-2:
Use a short length of 3/8” PEX to connect the UV device to
the provided
3/8” to ¼” PEX Union (item not shown) instead of the flow restrictor, cut a length of ¼”
PEX that will connect the union to the Faucet, and proceed to the faucet installation.
