Before one should discuss how to install the commercial RO plant, one must be familiar with the parts or components of the commercial RO plant. For that matter, the list has been provided below.

• RO Module: It is the main component and holds the pre-filters, membrane, and post-filter.
• Angle Stop Valve: The angle stop valve connects to the cold water line to supply water to the RO system.
• Pre-Filter 1: Melt Blown Polypropylene filter removes larger particles such as dirt, rust & sediment.
• Pre-Filter 2 (and 3 if applicable): 10 Micron carbon block removes chlorine and chemical contaminants in the feed water and protects the RO membrane.
• Shut-Off Valve: Automatic shut-off valve closes when the storage tank is full and shuts off the water supply to conserve water.
• Membrane: Reverse Osmosis Membrane thin film composite membranes reduces dissolved minerals, metals, and salts
• Post-Filter: A coconut shell activated carbon post filter is provided for a final "polish" and to remove tastes, odours and to provide great tasting water.
• Bladder Tank: Bladder tank holds RO purified water, ready to use.
• Drinking Water Faucet: The RO Faucet is used to dispense purified water when you want it.
• Drain Clamp:A wastewater saddle valve connects to the drain to remove reject water from the RO system.
• Tubing:Tubing connects all RO components.
• Quick-Connect Fittings:Quick-Connect fittings are used for necessary tubing connections. 

Step by step guidelines to install the RO water plant is as follows

• Faucet: If the sink has a sprayer, it may be disconnected for faucet installation. A pipe cap or plug will be necessary to seal the sprayer connection or sprayer can be left connected under the sink.

• Mounting the Faucet: With the help of a drilling machine, the holes must be driven in order to mount the faucet in the position.
• Angle Stop Valve and Tubing Installation:The John Guest Angle Stop Valve provides a simple, easy connection between the angle stop (cold water shut-off) and the bottom of the riser tube.

• Drain Saddle Valve Installation:A Drain Saddle is used to make a wastewater connection with the drain under the sink, which is designed to fit around a standard 1-1/2" OD drainpipe.

• Initial Tubing Connections:For convenience on under sink installations, it may be advisable to complete under sink tubing connections at this time.

RO Component Installation

• Cartridge Installation Required:The sediment cartridge, carbon block cartridge(s), and reverse osmosis membrane must all be installed in the RO unit.

• RO Unit Installation:The RO unit is normally mounted to the right or left sink cabinet sidewall, depending on where supply tank is to be located. Generally the unit is installed at the front of the cabinet and the tank at the rear.

• Pre-Fill and Supply Tank Placement:Pre-filling the storage tank is recommended so there is sufficient pressure to check for leaks and water to flush the carbon post filter.

• Final Tubing Connections
