UFR (Unmeasured-Flow Reducer) – Instructions for
Installation.

General – The "UFR - Unmeasured-Flow Reducer" should be installed in line, either in a
horizontal or vertical position, before or after the water meter. It is very important that the UFR
is installed so that the arrow on the UFR is in the direction of water flow.
The UFR - Unmeasured-Flow Reducer, does not require regular maintenance.

Options for installation (by model):

1. UFRs with a union nut connection can be connected directly to the water mete r and
the threaded male or female connection on the other side of the UFR, directly to the
piping.

2. UFRs, with threaded male or female connections on either side of the UFR, can be
installed directly to the piping.

Installation instructions:

1. Installation of the UFR with a union nut connection directly to the water meter:

A. Close the shut off valves upstream and downstream of the region that the

UFR is to be installed.

B. Match the direction of the arrow on the UFR with the normal direction of

water flow in the piping.

C. Connect the UFR’s male or female threaded connections to the piping, seal

using a sealant that is generally used for potable water systems.

D. Insert the attached seal (fiber, rubber or plastic) into the union nut of the

UFR, connect the union nut to the water meter, and tighten the union nut to
the water meter.

E. Open the shut off valves upstream and downstream and check for seal

tightness.

2. Installation of the UFR with threaded male or female connections directly into the
piping:

A. Close the shut off valves upstream and downstream of the region that the

UFR is to be installed.

B. Match the direction of the arrow on the UFR with the normal direction of

water flow in the piping.

C. Connect the UFR with threaded male or female connections, or to the piping

or shut off valve or water meter coupling. Use sealants that are generally
used in potable water systems.

D. Open the shut off valves upstream and downstream and check for seal

tightness.

water meter directly to the shut off valve and water meter coupling.

Prevention of malfunctions in the product during installation:

1. Rinse the pipe that you intend to attach the UFR to, in order to prevent large bodies
from entering the UFR.

2. Make sure not to let any sealant enter the UFR, especially the sealing region inside
the UFR.

3. Make sure to tighten the UFR using an appropriate wrench on the hexagon flats only.
