ATI Q46UV UV254/Turbidity Monitor
Part 1 – Introduction
General
This manual is a supplement to the manual for the UV-254/Turbidity Monitor.
It covers the installation and operation of the Q-Clean automatic sensor
cleaning system.
The Q-Clean is an automatic system that periodically cleans the UV sensor by
killing the sensor flowcell with a cleaning chemical. The chemical used is a
solution of “Red-B-Gone”, which is used to remove iron and manganese buildup.
Red-Boone is manufactured by Pro Products and an SDS on this chemical is
available at: https://proproducts.com/sds-sheets/.
Standard System
The Q46UV system with chemical cleaner is supplied as an integrated assembly
that includes the UV monitor, UV sensor and flowcell assembly, an automatic
chemical injection system, a sample flow control valve, and a chemical
reservoir. All components are mounted on a support panel and the system is
ready for operation once it is mounted and the sample is connected.
Cleaner Panel Assembly
As mentioned previously, the Q46UV system with chemical cleaning is
supplied already mounted on a ¼” thick HDPE plate. Figure 1 below shows the
assembled system with mounting plate dimensions. Mount the panel in a location
that allows easy access for calibration and maintenance.

Q-Clean Pump
The Q-Clean assembly uses a peristaltic pump mounted on the front of a
control enclosure. The pump operates for approximately 30 seconds during each
cleaning sequence. Pump operating time and the frequency of cleaning are
controlled by program settings in the Q46UV and can be adjusted to meet
specific application requirements. A typical cleaning cycle will consume
approximately 25 ml. of cleaning solution. A 500 ml. chemical bottle is
supplied and a bottle bracket is mounted to the panel assembly. Cleaning
frequency is normally somewhere between once a day and once a week, depending
on the severity of fouling. Only through experience can you determine the
required frequency.
Cycle Description
When the Q46 monitor calls for a cleaning cycle to begin, the cleaner
assembly will close the ball valve, stopping sample flow into the system.
Analog outputs and relays in the Q46 will be held at pre-cleaning values. Once
the flow has stopped, the peristaltic pump will activate, filling the flow
cell with cleaning fluid. After filling, the cleaning solution will remain in
the flow cell for the programmed time period (normally about 15 minutes) to
clean optical surfaces. At the end of the cleaning period, the ball valve will
reopen and flush out the cleaning solution. Analog and relay outputs will
remain in the “hold” state for the period of time defined in the Q46UV
program. Once that time period has expired, outputs will update as normal.
Cleaning Fluid Mixing
The Q-Clean system is supplied with a bottle assembly for holding 500 ml.
of cleaning solution. The solution must be mixed on-site. A bottle of
“Red-B-Gone” cleaner is supplied with the system. Disconnect the tube fitting
at the top of the cleaner bottle and remove the cap. Fill the bottle ¾ full of
tap water. Add two tablespoons of Red-B-Gone, close the container, and mix for
30 seconds. Fill the bottle the rest of the way to the neck of the bottle and
replace the cap. Place the bottle in the bottle holder and
reconnect the tube fitting. Note that the exact amount of chemical is not
critical. If using a disposable plastic spoon, simply add 3 or 4 spoonsful. A
little extra will do no harm and possibly help the cleaning process.
Electrical Wiring
The Q-Chem pump has two external items connected. A 3-conductor cable
connects the Q46UV monitor and a 2-conductor cable connects the sample inlet
control valve. In addition, AC power is connected to the Q46UV with a short
power cable. If desired, this can be removed and a separate AC power cord
used. Shown below are electrical terminal connections for the pump
system.

**Maintenance
**
General
The cleaner system requires very little maintenance. The only maintenance item
in the assembly is the peristaltic pump head. The tubing in the pump is a
replaceable part and will need to be changed periodically. The frequency will
depend on how often cleaning is done. The pump will normally run about 15
seconds during each cleaning cycle. Assuming one cleaning cycle per day, you
can probably go a year without problems. As a preventive procedure, replace
the peristaltic pump tubing once per year. The entire pump and pump motor
should last 2-3 years or more, again depending on cleaning frequency. The
pumps are inexpensive and replacements are available from ATI.
Tube Replacement
Tube replacement is a simple process. The peristaltic pump head is first
removed from the drive by pinching the tabs on either side inward and then
pulling the pump head off of the drive shaft.
Once you have removed the pump head, pinch in the tabs at the top and bottom
as shown in the picture on the right. The two halves of the plastic assembly
will separate as shown on the next page.
Inside the pump, you’ll find a roller assembly and the tube with retainer
clips. Take a new piece of tubing from the spares supplied. Place the retainer
clips on the new tube. They should be space exactly 1” from each end.
After clips are in place on the tube, wrap the tube around the roller assembly
taking care that the clips line up with the slots in the front plastic
housing. The opening in the clips faces outward when inserted into the pump
head. Press them into place and then replace the back piece. 
Once the pump tube is in place, put the pump head back onto the drive shaft and press in until the pinch points click into place so that the pump head is secure.
