Inlet Water Plumbing

Filtered water from a base filtration system 

should be connected to the inlet of the RO 

System.
Connect Beverage hose (not supplied) to 

the outlet of the base filtration system.

Before connecting to the RO System 

inlet, the plumbing from the base filtration 

system must be flushed clear of all debris. 

Hold a bucket at the inlet water line and 

slowly open the base filtration water valve. 

Allow the plumbing to flush until all debris 

is removed.

System Inlet Connection

The System Inlet has a 3/8” OD tube 

connection at the Inlet (Figure 9). 

Filtered Water Product Outlet 

Connection

The System Permeate has a 1/4” OD tube 

connection 

(Figure 9)

. Use 1/4” OD tubing, 

or larger (not supplied) to connect between 

the product outlet and the downstream 

equipment.

A Tee fitting should be installed in this line 

from the system to connect to a tank (not 

supplied)(Figure 10).
It is recommended that a shut-off valve be 

installed in the line to the tank.

Install Pre-filters and RO 

Membrane

If not already installed, install the Pre-filters 

and RO Membrane. 

The white sediment prefilter must be 

installed in the 

left

 prefilter housing, 

closest to the water inlet.

The carbon prefilter must be installed 

in the 

right

 prefilter housing, after the 

sediment prefilter.

The RO membrane 

must

 be installed with 

the brine seal on the right, nearest to the 

RO membrane housing inlet. It should only 

be inserted into the RO housing from the 

right side.

1. 

Pull out the tube which is inserted 

into the RO housing’s inlet (Figure 

11a)

2. 

Using the supplied wrench, 

unscrew the RO housing end cap 

and insert the RO membrane into 

the housing. The RO membrane 

must be installed with the brine 

seal on the right side, nearest to 

the RO membrane housing inlet. It 

should only be inserted into the RO 

housing from the right side.
