The following steps will enable you to install the system quickly and orderly. Some variation may be necessary depending
on the installation. See page 4 for a check list of tools and materials.
typical installations follow this sequence:
1. Select Component Installation Locations
2. Faucet Installation
3. Install Adapter Valve on Water Supply
4. Connect System Drain
5. Install Reservoir Tank
6. Install Filter System Assembly
7. Start-Up
Step 1 – Select Component installation Locations
• Dispenser Faucet – The faucet is designed to be mounted on the rear lip of the sink. It may be installed in an existing
sprayer attachment hole or in a hole drilled at the time of installation. It may also be mounted to an adjacent counter
top. It should be positioned so that water is dispensed over the sink. A 7/8” diameter hole is required.
• important considerations:
• Access to the bottom (undersink) of the faucet is required for attachment of product water line.
• There should be no undersink obstructions which would prevent smooth tubing runs to the drain connection, or RO
module assembly.
• Filter System assembly – The filter system assembly is designed to be mounted on any rigid vertical surface such as a
cabinet sidewall, sheetrock in exposed stud. It should be positioned such that there is access to an inlet water source
and drain. The installation should also allow convenient access for servicing.
• inlet Water Supply Connection – Once a location is chosen for installation of the filter system assembly, select a nearby
cold water line to provide the water source for the system.
Note: Follow all local plumbing codes when connecting to service water.
• the Reservoir tank – Position the reservoir tank near the faucet for optimum convenience. The reservoir tank will weigh
about 28 pounds (13 kg) when full of water, so it must be positioned on a stand.
The reservoir operates best in the vertical position, but it will operate on its side.
• Drain Connection – The most convenient entry to the drain is directly above the P-trap of the kitchen sink. However,
the drain water from the system can be connected to adjacent sinks or a floor drain. Extra care should be taken when
entering drains near dishwashers or food waste disposals as back flow may occur through the air gap and cause
flooding.
Note: Follow all local plumbing codes when connecting to drain.
