INSTALLATION GUIDE

2

3

Prepare site and plan for installation

Prior to installation, read the entire manual to familiarize yourself with the system, and determine  
the best location for installation. Ensure you check and comply with all local plumbing codes.

STEP 2 - Connect the feed water valve

STEP 3 - Install the tank

TO CONNECT:

1  

 This system comes with installation tubing. To 
assemble the tubing, measure the required length 
and cut.

2  

 With a utility knife, create a clean, square edge for 
each tubing. Measure 3/4" from the end and mark 
with a permanent marker.

3  

 Remove the lock clip and insert the tubing into  
the lock sleeve, until the mark almost disappears. 
Re-install lock clip.

TO DISCONNECT:

1  

 Remove the lock clip.

2  

 Gently push the lock sleeve down against 
the fitting body.

3  

 Keep the lock sleeve pushed down and 
pull on the tubing to remove.

This system features quick-connect fittings.

STEP 1 -  Position the system and tank

Turn off the cold water supply to the sink.

2

  Turn on the kitchen cold water faucet to release 

pressure and allow water to drain from the line.

Apply plumber’s tape 4 or 5 times clockwise 
around the nipple on top of tank in the same 
direction as threads.

Screw the tank shut-off valve onto the threads 
by hand. Do not over-tighten.

Place the tank on its stand and position it in the 
desired location.

3

  Disconnect the faucet connector pipe from the 

cold water supply. Place a towel underneath to 
catch any drips. 

4

  Configure the feed water valve to match the 

connection on the cold water supply.

5

  Attach the feed water valve to the cold water 

supply. Reconnect the faucet connector pipe to 
the feed water supply valve.

Note: Do not over-tighten.

TIP  

Temporarily place System Manifold, Remineralizer, 

and Tank into the under sink cabinet or desired location to 

ensure adequate space and proper positioning.

1   

This system is designed to be installed under the 
sink, but wherever installed, the system requires 
access to a cold water supply, a drain line, and 
120-volt AC power. Ensure the power supply is 
properly grounded and meets all electrical code 
requirements. A remote installation should be 
close enough so no more than 15' of tubing are 
required to run from the RO System and faucet. 
The RO System should not be located more 
than 10' below the faucet. Excessive distance or 
height difference will reduce the flow rate of 
the treated water. Depending on the distance 
between the system and the faucet, more 
tubing may be required to install the system. If 
required, use drinking-water rated polyethylene 
tubing with a 1/4" outside diameter.

2   

Select a location for the RO System Manifold, 
the Remineralizer and the Storage Tank. 
Temporarily place the components in the 
desired location to ensure adequate space 
and proper positioning. Allow at least 3" of 
clearance between the floor and the bottom 
of the filter housings to allow ample space for 
filter changes. To help gauge the right location 
for the System Manifold, temporarily assemble 
the filter housings into the Manifold for 
reference.

3   

The back plate of the System Manifold includes 
two keyhole slots used for hanging the unit on 
a wall with (2) #10 mounting screws. The screws 
should be threaded into a surface capable 

of supporting the weight of the system. 
The instructions below assume that you are 
mounting the unit to a cabinet wall. If you are 
mounting to drywall or a similar surface, use 
the appropriate anchors.

4   

Mark wall placement for mounting screws using 
the diagram below. Ensure that the holes are as 
level as possible. 

5   

Drill two pilot holes for the mounting screws 
using a 1/8" drill bit.

6   

Insert two #10 screws into the mounting holes, 
leaving approximately 3/8" of each screw 
exposed.

7   

Hang the System Manifold on the mounting 
screws. During installation, you can temporarily 
remove the unit from the wall to improve 
access to various components.
