Run the other end of the tubing to the QuadPro SST reverse osmosis unit, approximately close to where its final position will be. Using a tube cutter, cut the tubing to a desired length. Use fitting installation elbows as needed.

8 INSERT FILTRATION CARTRIDGES

Remove the front faceplate of the unit by lifting up on the bottom of the magnetized faceplate connector and pulling upwards. Set aside the faceplate.

Insert the replacement cartridges into the unit in the order shown by pressing the cartridge until an audible “click” sound is heard. Ensure that the handle is in the “locked” position. Repeat with the remaining cartridges.

Top: Pre-Filter Cartridge
Middle: Post-Filter Cartridge
Bottom: RO Cartridge

NOTE: Filtration cartridges may come pre-installed in the unit. In this case, remove each cartridge and inspect for any packaging. Re-install each cartridge once it is confirmed that no packaging is present on the cartridge or in the cartridge port.

a) LIFT AND PULL UP

9 CONNECT TRANSFORMER AND TEST FOR LEAKS

Connect the power transformer to the connection on the QuadPro SST. Turn the cold water supply on by hand rotating the shutoff valve handle in the counterclockwise direction and ensure the John Guest valve will allow flow to the unit. Check for leaks around the raw water connections, including the John Guest valve and the raw water input on the unit.

a) John Guest Valve Handle should be in the “up” position

10 PLUG UNIT IN TO POWER SOURCE

Plug unit into the designated power supply. The pump will begin to run and will initiate its startup cycle. During startup, water will run to the drain. The startup cycle will last for approximately sixteen minutes. Once the pump stops making noise and water stops running to the drain, the startup cycle is complete.

Ensure that the indicator lights are white for each filter cartridge. For more information on the indicator lights, see page 11.

NOTE: Prior to plugging unit in, ensure that all water connections have been made and are secure. Plugging the unit in activates the pump and may result in significant water leakage if all connections are not made.

11 CLEAR WATER LINE

Turn the RO faucet on and let run for a full fifteen minutes. Ensure that no air pockets are observed following the fifteen minutes of run-time.

Once complete, shut off the RO faucet and do a final check for leaks, inspecting each of the connections. If no leaks are present, position the unit in its final location.

1 INSTALL FAUCET BASE ASSEMBLY

Using a 2.5mm Allen wrench, remove and set aside the hex bolt on the rear of the faucet base assembly.

If the sink does not have an existing 0.8-1.2 inch hole pre-drilled, such as for an existing spray attachment hole, the sink top will need to be drilled.

Note: If the sink has a pre-drilled hole of a larger diameter than instructed to drill herein (0.8-1.2 inch), it is necessary to purchase a suitable escutcheon or cover plate adequate for the pre-drilled hole. Such a part/kit is not included in the IAPMO certification of this system to CSA B483.1

Insert the faucet base assembly into the designated hole on the sink top. Orient the faucet base assembly so its rear (where the hex bolt was removed) is facing away from the sink.

Using a Phillip’s screwdriver, tighten the two screws visible on the top of the faucet base assembly.

Once the screws are tightened, the faucet base assembly should rest snugly, without any “give” or movement.

a) Tighten

2 INSTALL FAUCET ONTO BASE ASSEMBLY

Remove the rubber screw cap from the rear of the faucet and set aside. Insert the power cord connected to the faucet through the center of the faucet base assembly. Slide the faucet onto the base assembly in the orientation shown and push down until fully inserted.

Using a 2.5mm Allen wrench, insert and tighten the hex screw into the faucet base assembly. Replace the rubber screw cap.

3 CONNECT FAUCET AND POWER

Because the performance of a reverse osmosis membrane is highly dependent upon Pressure, Temperature, and Total Dissolved Solids (TDS), this data should be used for comparison only.
Lower temperatures are directly proportional to a slower flow rate. The reverse osmosis system should not be installed in a location susceptible to freezing. Incoming water temperature should not exceed 100° F (37.7° C).
The more TDS in the supplier water, the more filter time required. Incoming TDS should not exceed 1,000 ppm. Higher water pressure enables a higher flow rate. Pressure must be above 40 psi for proper system operation.
Flow rate and output are determined by three factors:
1. Incoming water temperature
2. Total Dissolved Solids (TDS) present in supply water
3. Incoming water pressure

ARSENIC FACT SHEET

INTRODUCTION:

This system has been tested for the treatment of water containing pentavalent arsenic (also known as As(V), As(+5), or arsenate) at concentrations of 0.05 mg/L or less. This system reduces pentavalent arsenic but may not remove other forms of arsenic. This system is to be used on water supplies containing a detectable free chlorine residual at the system inlet or on water supplies that have been demonstrated to contain only 50 ppb (0.050 mg/L) pentavalent arsenic. Treatment with chloramine (combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section below for further information.

ARSENIC FACTS:

Arsenic (As) is a naturally occurring contaminant found in many ground waters. Arsenic in water has no color, taste or odor. It is measured by a laboratory test. Public water utilities must have their water tested for arsenic. You can get the results from your water utility. If you have your own well, you can have the water tested. The local health department or the state environmental health agency can provide a list of certified labs. Information about arsenic in water can be found on the internet at the U.S. Environmental Protection Agency website (epa. gov/safewater/arsenic).

There are two forms of arsenic: pentavalent arsenic (As(V), As(+5), and arsenate) and trivalent arsenic (also called As(III), As(+3), and arsenite). Although both forms of arsenic are potentially harmful to human health, trivalent arsenic is considered more harmful than pentavalent arsenic. In water, arsenic may be pentavalent, trivalent, or a combination of both. Special sampling procedures are needed for a lab to determine what type and how much of each type of arsenic is in the water. Check with the labs in your area to see if they can provide this type of service.

If you get your water from a public water utility, contact the utility to find out if free chlorine or combined chlorine is used in the water system. The system is designed to reduce pentavalent arsenic only. It will not convert trivalent arsenic to pentavalent arsenic. This system was tested in a lab. Under testing conditions, the system reduced 0.050 mg/L (ppm) pentavalent arsenic to 0.010 mg/L (ppm) (the USEPA standard for drinking water) or less. The removal performance of pentavalent arsenic of the system may be limited due to water quality conditions (i.e. iron-containing water or other water quality conditions). Have your treated water tested for arsenic to check whether the system is working properly.

The QuadPro Membrane must be replaced every 48 months to ensure system will continue to remove pentavalent arsenic. The component identification is listed in the installation/operation manual.
