Feedwater Parameters

To reduce the risk associated with property damage due to water leakage:
• Read and follow Use Instructions before installation and use of this system.
• Installation and use MUST comply with all state and local plumbing codes.
• Before installation, shut-off main water supply and depressurize and drain pipes.
• Do not install systems in areas where ambient temperatures may go above 110° F (43.3° C).
• Do not install on hot water supply lines. The maximum operating water temperature of this filtration system is 100°F (37.8°C).
• Do not install if water pressure exceeds 100 psi (689 kPa). If your water pressure exceeds 80 psi (552 kPa), you must install a pressure
limiting valve. Contact a plumbing professional if you are uncertain how to check your water pressure.
• Do not install where water hammer conditions may occur. If water hammer conditions exist you must install a water hammer arrester.
Contact a plumbing professional if you are uncertain how to check for this condition.
IMPORTANT NOTE: Be sure to confirm that the feedwater falls within the limits shown below. If unsure of the feedwater quality, check
with your 3M distributor:

* May be operated up to 1400 ppm water, however outlet TDS may exceed steamer requirements if over 800 ppm. If TDS is over 1400 ppm and /or hardness over
10 grains (171 mg/L), a softener is recommended.

Equipment Set-up and Installation

Equipment Location

Prior to installing the TFS450 RO filtration system components, carefully plan the installation location for all system components.
Obtain additional hardware for plumbing connections (as needed).
1. Position the auxiliary storage tank in the desired location.
2. The TFS450 RO filtration system should be installed within 15 ft (4.6 m) of the tank.
3. The TFS450-BP water booster pump (if installed) should be installed within 10 ft (3.05 m) of the TFS450 RO filtration system.
4. Access to feed-water and drain line connections are required.
5. All components should be accessible and have at least 6" (15 cm) of clearance on all sides to facilitate servicing.
Mounting the TFS450-RO Filtration System
1. Locate the position of the assembly. The horizontal hole spacing is 16" (40.6 cm) center-to-center.
2. Draw a level line on the wall where bracket is to be mounted. Measure and mark locations for screws.
3. Install mounting screws (not included) into each of the hole locations. Be sure to leave ¼" (0.6 cm) space between the
bottom of the screw head and the wall so that the bracket can be hung.
To reduce the risk associated with property damage due to water leakage:
• Mount filter in such a position as to prevent it from being struck by other items used in the area of installation.
• Ensure that the location and fasteners will support the weight of the system when installed and full of water.
4. Hang the assembly from the mounting screws.
5. Once the bracket is hung, tighten the mounting screws so that the bracket is snug between the screw and the wall.

Plumbing Connections

1. If using the TFS450-BP water booster pump, please refer to the TFS450-BP water booster pump Owners Manual.
2. Inlet Side of TFS450 RO filtration system:
• Install the ½" inlet-water shut-off valve and nipple as supplied with the installation kit on the inlet (left) side of the pre-
filter head. Install ½" tubing from the inlet water source or from the TFS450-BP water booster pump to the inlet-water
shut-off valve on the TFS450 RO filtration system. The fitting to the inlet water shut-off valve is ½" NPT (female).
3. Outlet Side of TFS450 RO Filtration system and Sample Valve:
• Install a ½" nipple and ball valve to the tee outlet and to the leg of the tee. The valve on the leg of the tee is for pressure
release, flushing and sampling. Install ½" tubing from the opposite side of the tee to the downstream equipment.
4. Reject Connection:
• Run a / " tube from the reject to drain port on the TFS450 RO filtration system to the drain.

WARNING WARNING
To reduce the risk associated with the ingestion of contaminants:
• An approved air gap must exist between the RO System reject drain line and the drain opening to meet
plumbing codes.

Storage Tank Connections:

IMPORTANT NOTE: A pressure relief valve (not included) should always be installed on the storage tank plumbing line.
A pressurized external storage tank (purchased separately) is required to achieve the short-term demand volumes and flow
rates for downstream equipment. Choose the tank size to match the short-term volume requirement of all downstream
equipment. Part numbers and draw down volumes for three tanks are included below.

• Check the air precharge pressure in the tank using the Schrader
should read slightly less than 30 psi (207 kPa). Adjust the air pressure to about 30 psi (207 kPa) using procedure on
Page 11.
• Place the tank in an area where it will not be bumped or jarred.
• Using the ½" tubing from the installation kit connect one end to the product bulkhead fitting – outlet to tank on the TFS
450 RO filtration system. The tank and bulkhead fittings are each quick connect.
IMPORTANT NOTE: Do not connect the opposite end to the tank until after reading the following.
• It is recommended that the pressure regulator be checked and adjusted at this time and before startup. The automatic bypass
delivers (non-RO) water to maintain the demand flow rate. This occurs when the pressure in the tank falls below the regulator's
set point and is unable to deliver RO water. The downstream equipment will thus never be starved for product water even
during periods of high demand.
• Cut the tubing at a convenient point and install the tank sample valve kit from the installation kit (½" quick-connect
fittings). This valve may be used to drain the tank and to procure product water samples. Provisions to collect and/or to
drain the water taken from this valve must be considered.
• Connect the remaining tubing from the sample valve to the tank.
