2 Overview
Thank you for purchasing from Real Tech Inc.
The Real Clean System I is an automatic chemical cleaning system for use with
any Real Tech Inc. M2000 or M3000 series analyzers. The purpose of the
system is to reduce fouling of the flow cell within the analyzer.
The Real Clean and M series Analyzer are plumbed so that process water goes through the Real Clean to the
Analyzer. When a cleaning cycle starts, the Real Clean system halts input of process water and pumps
cleaning solution from its wash bottle to the flow cell of the M series analyzer on a timed schedule, or when
needed, immediately through manual intervention.
A portion of cleaning fluid is recaptured and directed back into the wash bottle after a cleaning cycle is
completed. Analyzer measurement resumes after the tubing is cleared of residual cleaning fluid by influx of
process water.
The cleaning system is controlled through the Operator Interface of the Real Tech M series 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.

5.4 Plumbing
Process water from a pressurized source flows through the Real 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 Real Clean system.
The Real Clean system is connected in series with the instrument to be cleaned. It is preferred to keep the
tubing between the Real Clean and instrument less than 2 feet. Configurations for the M series instruments are
outlined in Figure 5.6.
Note: If installing with a Dual Feed system, the Real 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.

6 Start Up and Operation
6.1 Start Up
Once plumbing and electrical connections have been made, you need to enable the cleaning system and enter
settings for cleaning configuration. This is accomplished through the M Series Analyzer’s Operator Interface.
Section 8 gives more detail on menu selections.
From the main menu, press the down arrow button to scroll to the +Cleaning system menu. Access the Main
Menu page by pressing the Menu button. You may need to press the button more than once to have the screen
displayed.
1. To enable the cleaning system, scroll down to ‘Enable Clean’ and press Enter to enable the cleaning
system. The 0 turns to 1, which signifies the item has been selected and therefore, enabled.
Scroll down by
pressing the down
arrow repeatedly.
Press Enter to
expand the
+Cleaning System
menu.

Real Clean System I v 2.1
Real Tech Inc. 12
2. Scroll down from the last entry until the +Clean Frequency menu is displayed. Expand the menu by
pressing the Enter button. Seven selections are available. The default is 4: 3 days. De-select a
frequency by scrolling to it, and then pressing Enter to remove the checkmark. Conversely, select an
option by scrolling the arrow to it, and then press Enter to place a checkmark beside it.
Implementing these two settings is the minimum you need for set up. The system is ready for use. For all other
functions, refer to Section 8, Cleaning Configuration. If the system encounters any problems, associated alarms
or warnings are displayed on the Operator Interface of the M Series Analyzer.
To turn the Real Clean System off, disable the device by removing the checkbox opposite Enable Clean
(reverse of step 1).
6.2 Operation
The system consists of a 3-way stainless solenoid valve, a peristaltic pump, and a 1L chemical cleaner storage
container. The cleaning process is initiated automatically on a preselected time interval or can be manually
triggered.
The cleaning process consists of the following steps:
1. Solenoid shuts off the process water flow to the analyzer flow cell (LED turns on).
2. Solenoid opens flow from peristaltic pump to the analyzer flow cell.
3. Peristaltic pump turns on and pumps cleaning solution into the analyzer flow cell.
4. The pump turns off and the system waits to allow the chemical cleaning solution to remove fouling and
staining present on the walls of the quartz flow cell.
5. The pump turns on in the opposite direction to re-capture the cleaning chemical.
6. Solenoid valve opens the water flow from the process to purge out the cleaning solution (LED turns off).
The process is now complete.
During the cleaning cycle, the measured UVA/UVT value shown on the M series instrument is held to the last
value measured before the cycle started and released after the purge time is complete.

7 Cleaning
The Real Clean system comes with a 1L chemical storage bottle. After
a cleaning cycle, approximately 85% of the used cleaning fluid is
pumped back into the bottle reducing the need to replenish the fluid
on a regular basis.
Two important factors that affect the sensor performance are the
cleaning fluid used to clean the flow cell, and how often the flow cell
is cleaned (cleaning frequency).
Cleaning Frequency
The optimum frequency of cleaning is quite variable depending on
the amount and type of fouling agents in the water. This will be
dependent on the application and installation point.
For wastewater, a higher frequency will be required (ex. 1-24hrs)
whereas high purity water will require a lower frequency (ex. once a
month). Each installation will be different and require configuration
onsite.
Once in operation, observe the flow cell for signs of fouling prior to
the first cleaning cycle. If fouling is present, increase the cleaning
frequency accordingly. The measured data can also be observed for
signs of a saw tooth effect as shown in Figure 7.1. If the saw tooth
shows an upward trend, as shown in Figure 7.2, the sensor is drifting
and cleaning frequency must be increased.
Cleaning Fluid
Selecting an effective cleaning solution is essential for optimal
performance. The following commercial cleaning solutions and acids
are readily available to remove common fouling agents.

cleaning fluid to the sensor. The pumping time should be configured to ensure the cleaning
fluid reaches and fills the quartz flow cell prior to the 10-minute holding period. Longer
distances between the cleaning system and sensor will require a longer pumping time. Default
setting is 120 seconds, suitable for a tube length of 24-36 inches.
-Clean Frequency
Clean Frequency allows the frequency of cleaning to be configured i.e. hour, day, week, or
month. Default is 3 days.
