Introduction
This manual gives you the information necessary to successfully unpack, install,
operate, and maintain the Ultra DI 50 liquid optical particle counter.
The Ultra DI 50 particle counter samples deionized water to monitor the presence of
particles. Laser illumination with a high-resolution optical system, collects particle-
scattered light. Determination of particle size is accomplished with pulse height
analysis (PHA) of the scattered light. The Ultra DI 50 particle counter detects particles
0.05 µm and larger. See Specifications on page 1-4 for more details.
Water passes through the instrument's sample cell at a flow rate set by an attached
flow controller. The particle counter is designed for a flow rate of 1000 ml/minute and
a sample rate of 3.75 ml/minute.
Sample data is transferred to a user interface for analysis and accumulation. The user
interface most frequently used is Facility Net software and a PC display. Facility Net is
a Particle Measuring Systems software application that controls the Ultra DI 50 particle
counter and other Particle Measuring Systems instruments, collects the sample data
of interest to the user, manages alarm settings, and displays the data in a manner set
by the user.
The Ultra DI 50 particle counter also generates 4-20 mA output for input to other
control systems.

Outlet
A Flaretek®fitting that connects the particle counter to a flow controller.
When the particle counter is idle, cap this fitting to retain water within the sample cell.
Inlet
A Flaretek fitting that connects the DI water source to the particle counter.
When the particle counter is idle, cap this fitting to retain water within the sample cell.
Status LED
Displays red or green to indicate the instrument’s operational status.
When the particle counter receives power, its status light illuminates red while laser
diagnostics are performed. After 5–10 minutes, the laser will stabilize, and the status
light will turn green. If the status light flashes red, the sensor has failed to initialize
correctly.
Facility Net’s alarm settings control this light. The status light will turn red if the laser
is not operating correctly.
For more information about the status LED, see Chapter 7, Troubleshooting.

If all of the materials are included and undamaged, store the packing materials. It is
important to keep these materials because warranties may not apply if return
shipping containers are inadequate.
CAUTION
The Ultra DI 50 particle counter is filled with filtered propylene glycol before shipping.
The propylene glycol must be removed immediately and replaced with deionized water.
Failure to remove the shipping fluid can result in contamination of the sample cell.
If the particle counter is not in use, ensure that it is always filled with deionized water.
Never allow it to go dry.
NOTE: The provided handles are to be used only for lifting and moving the
instrument by one or two persons.

Installation
Selecting a Location
>> To choose an effective location for the particle counter, consider the following
issues:
Accessibility
The particle counter should be readily accessible for connecting and
disconnecting cables, etc.
Visibility
The front panel should be visible from a reasonable position.
Plumbing
The particle counter should be located near the deionized water source so that
the tubing has no sagging or dead spots where particles might accumulate.
Cables
The unit should be located near a source of grounded electrical power, whatever
communication ports you wish to use, and any other devices with which it must
communicate. Cables should not be strained or constricted.
Chassis clearance
The external air filter and the cooling air discharge (on the sides of the chassis)
should not be obstructed.
Drainage
When completely installed, the particle counter will have a flow controller
connected to the DI water outlet tube. Water passing through the flow controller,
will drain to waste. The drainage site should be close enough that displacement
of the tubing and subsequent spillage does not occur.

Completing Installation
>> To complete the installation of the particle counter, the following operations
must be performed:
• Ensure that you have all the additional components (other than those shipped) to
install, initialize, and operate the monitor.
See Minimum Required Components, below and Other Components on page 2-4.
• Connect the tubing.
See Connecting the Tubing and Flow Controller on page 2-5.
• Connect the cabling required for your installation.
See Chapter 4 4-20 mA Output and Configuration
• Connect your cabling to the device that will receive the data output, usually an
Ethernet hub.
See Chapter 3 TCP/IP Set Up (Configuration)
• Ensure that the external air filter is still positioned correctly — in its channels and
pushed fully in.

Connecting the Tubing and Flow Controller
You will need three segments of Teflon tubing at lengths suitable for your operation.
You will be connecting between the following items:
•from the DI water source to the particle counter inlet
•from the particle counter outlet to the flow controller inlet
•from the flow controller outlet to drain
Prepare Tubing
Your tubing must have 1/4-inch Flaretek fittings where it connects to the inlets and
outlets of the particle counter and the flow controller.
>> To install Flaretek fittings using the flaring tool:
1. Cut three pieces of tubing for the three connections listed above, making the pieces
a little longer than you think they must be. It is easier to adjust the finished tubing
by cutting a little off rather than having to cut an entirely new piece of tubing.
2. Place the flaring tool on a solid surface.
3. Select the piece of tubing that will connect from your DI water source to the particle
counter inlet fitting.
4. Place a Flaretek screw-down cap over the end of the tubing you will be flaring. The
threaded part of the cap should face the end you will be flaring.
5. Heat the tubing end with a heating gun until the tube is transparent but still holding
its shape.
6. Push the tubing over the flare molding part of the flaring tool.
7. Allow the tube to cool. The flared end will lose its transparent look.
8. Repeat steps 4through 7for the other two pieces of tubing.
NOTE: Only one end of the flow controller’s discharge tube may require
flaring.
9. Now you are ready to connect the tubing (see Connect Tubing on page 2-6).
NOTE: If the flow controller is not the FC-100, ensure that it can be set to a
flow rate of 1000 ml/minute.
