2 Overview

Thank you for purchasing from Chemtrac, Inc.

The Automatic Cleaning Module is a chemical cleaning system for use with the

Chemtrac UVM5000 UV254 Organics Monitor, and the UV1 UV254 Organics

Sensor. The purpose of the system is to reduce and clean any deposition/fouling

in the analyzer flow cell.

The Auto Clean and the UV254 analyzer are plumbed so that process water flows through the cleaning module

to the analyzer. When a cleaning cycle starts, the Auto Clean temporarily stops the flow of process water, and

instead pumps cleaning solution from its cleaning fluid bottle to the analyzer flow cell. This can be done on an

automated periodic schedule, or on an immediate basis through manual intervention.

A portion of cleaning fluid is recaptured and directed back into the bottle after a cleaning cycle is completed.

Analyzer measurement resumes after the tubing is rinsed of residual cleaning fluid by the reestablished flow of

process water.

The cleaning system is controlled through the Operator Interface of the Chemtrac UV254 analyzer. From here,

the system is enabled, and a cleaning frequency is selected.

Cleaning of the flow cell is best achieved when cleaning frequency and cleaning fluid work in unison to prevent

the accumulation of fouling agents inside the flow cell.

On schedule,

from bottle by

pump.

5.2 Assembly

BThe cleaning fluid bottle holder must be mounted onto the Auto

Clean system from the underside of the enclosure as shown in

Figure 5.1. Fittings are supplied with the holder.

After mounting the enclosure, fill the 1L bottle with cleaning fluid.

Recommended fluids are outlined in Section 7 –Cleaning. Connect

the tubing from the system to the spout on the bottle.

5.3 Mounting

The system is enclosed in a wall-mountable cabinet.

The cabinet should be attached at all four of the

mounting holes provided (top left and right; bottom left

and right in Figure 5.2).

Use screws and washers that are sturdy enough to

support the cabinet weight of approximately 10 lbs.

Cabinet dimensions are to the nearest 1/8 inch. Refer

to Section 11, Cabinet Dimensions and Clearance for

drawings of dimensions and clearance.

The expanded view at right (Figure 5.3) shows

an example of a ¼” bolt and washer inserted in

the front side of the cabinet.

The system should be mounted in a convenient

location near the UV254 analyzer to be cleaned

(less than 2 ft.).

5.4 Plumbing

Process water from a pressurized source flows through the Auto Clean system and into the connected

instrument for measurement.

Piping is required to be ¼” OD flex tubing of whatever pressure rating is needed for the particular site. Figure

5.4 displays the two push-to-connect inlet and outlet ports on the side of the Auto Clean system.

The Auto Clean system is connected in series with the instrument to be cleaned. It is preferred to keep the

tubing between the Auto Clean and instrument less than 2 feet. Configurations for the UV254 analyzer are

outlined in Figure 5.6.

Note: If installing with a Dual Feed system, the Auto Clean will be installed prior to the Dual feed on the Stream

1 port (See Figure 5.5). Refer also to the Dual Feed manual for further instructions.

5.4.1 Connecting a UV254 Analyzer

1. Connect ¼” OD flex tubing from a pressurized source to

the IN port on the Auto Clean system.

2. Connect ¼” tubing from the OUT port on the Auto Clean

to the IN port on the side of the analyzer.

3. Connect ¼” tubing to the OUT port on the analyzer and

divert to drain.

IMPORTANT: The test water must be allowed to flow unrestricted to

drain so that no significant pressure will occur inside the flow cell.

IMPORTANT: If system was supplied with Dual Feed Option, be sure

to review the Dual Feed manual for additional plumbing information.

5.5 Electrical and Communication

The power and communication line from the UV254

analyzer feeds into the Auto Clean system via an

electrical conduit fitting at the bottom of the cabinet. The

system is powered and controlled through the

connected UV254 analyzer.

Connections at the analyzer are shown in Figure 5.7.

•White and green wires to terminal 7 and 8 (Clean

Out). Polarity is not important.

•Black wire to terminal 9 (24 VDC Out -).

•Red wire to terminal 10 (24 VCD Out +).

The terminal block connections at the Auto Clean

system control board are shown in Figure 5.8.

1. Connect the white and green wires leading from

the UV254 analyzer to the right terminal block.

Polarity is not important.

2. Connect the power wires leading from the

analyzer to the left terminal block. The black

power wire connected to the left (-) terminal and

red wire to the right (+) terminal.
