Final Tubing Connections
With all components in place, complete final tubing connections using these guidelines
Tubing should follow the contour of the cabinets.
Cut tubing to desired length using square cuts or a proper cutting device.
Ensure there are no sharp bends
Proceed with final tubing connections using the provided flow diagrams and the following procedures.
1
Connect the blue tubing from the faucet to the RO units post carbon filter outlet elbow fitting
2
Be sure the storage tank shutoff valve is in the closed position
Use the supplied syringe and add 5ml of the supplied sanitizing solution to the green tank tubing attached to the storage tank. Connect the open end of the green tubing from the tank to the RO units post carbon filter inlet tee fitting. Leave the tank valve closed.
3
Connect the orange tubing from the angle stop supply valve to the RO unit at the sediment filter inlet fitting
When facing the unit, this is the far right sump.
Permeate Pump Installation - If the system is equipped with a permeate pump, clip the pump to the membrane housing using the supplied mounting bracket and make the connections to the pump using the label on the pump and the flow diagrams provided. The BRINE OUT connection will be made in the following step.
4
Connect the 1/4" black tubing from the RO unit to the drain saddle
If the system is equipped with a permeate pump, run a length of tubing from the "Brine Out" port on the permeate pump to the drain saddle connection.

Ice Maker Hookup (Optional)
The RO drinking water system can be connected to any standard refrigerator ice maker or ice maker / water dispenser. 3/8" tubing must be used for ice maker connections. If your system is using 1/4" tubing for the tank and faucet, it will need to be changed to 3/8" tubing. (Do not connect to a commercial type bar ice maker.)
To complete this operation, connect a tee with shutoff valve into the faucet tubing (Blue Line) and route tubing to the refrigerator.
NOTE: Hooking up to an existing copper line is not recommended as RO water can cause the copper to leach into the water stream
Shut off the ice maker prior to turning off the existing tap water supply line to the refrigera- tor. Connect the RO system tubing to the ice maker inlet. Turn on the ice maker after the RO system has been flushed several times and the tank has a full supply of water. There are detailed instructions and a layout drawing on page 23.
NOTE: Before any service is performed on the RO system, turn off the ice maker valve and ice maker unit. Turn back on only after the RO tank has been flushed and is full of water.
