Purenex Multipure Aqua RO System - Manual (Page 5)

NOTE: The Reverse Osmosis Models come with an air gap faucet. To install, you will need a 1/8”, 7/16”
and 1” drill bits. Minimum mounting hole size: 1.00”; Maximum mounting hole size: 1.25”.
Maximum torque on toggle bolt: 5lb.in.
Proceed as follows:
Step 6 Follow the instructions for drilling a hole in your
sink (Steps 1 through 5)
Step 7 Gather and identify the faucet components.
Step 8 Remove the faucet base (with tubing attached) and
faucet spout from their respective plastic bags. From
above the sink, feed the faucet tubing and toggle bolt
down through the 1.00” to 1.25” mounting hole in the
sink. Ensure that the soft rubber gasket is uniformly
positioned between the base and the top of the sink.
Step 9 Align the faucet base so that the handle is on the right
side and the base is sitting flush on the sink top. Turn
the handle down (towards you) to the ON position to
reveal the tightening screw (located where the spout will
be inserted). Using a phillips head screwdriver, turn the
screw clockwise until the toggle bolt secures the faucet
base snug onto the sink top. Do not over-torque toggle
bolt (5lb.in max).
Step 10 Once the faucet base is securely fastened to the sink top,
insert the faucet spout into the faucet base until it is fully
seated. Turn the handle up (away from you) to the OFF
position.
Step 11 TUBING CONNECTONS:
NOTE: Do not cut any tubing at this time. Proceed with
tubing installations when you get to the pages noted
below.
Blue Tube from the faucet should be connected to the MP750SI
Final Filter as shown on page 9.
Red Tube from the faucet should be connected to the waste
water output port on the RO system as shown on page 8.
Black Tube from the faucet should be connected to the drain
as shown on page 8.
