DEPOLOX®3 PLUS RESIDUAL ANALYZER
INTRODUCTION
The Depolox 3 plus Residual Analyzer is a low, cost economical analyzer
for potable water that continuously measures either free or total chlorine,
chlorine dioxide or ozone residuals using proven amperometric measure-
ment technology. There is also an arrangement available for measuring
pH or flouride.
The Depolox 3 plus analyzer consists of two separate components: a “wet
side” package containing the sensor/cell and an electronic control pack-
age.
The electronic package is available for either 115 or 230 volt operation.
A single input arrangement is used when only a disinfectant measurement
(free or total chlorine, chlorine dioxide, ozone) is required. A dual input
arrangement is available when either pH or fluoride measurement is re-
quired in addition to a disinfectant measurement. Note that for pH- or
fluoride-only measurement, the dual input electronic package is required
and the dual input cannot be used for two disinfectant measurements. The
electronic package provides for operator input via plain-text-assisted,
self-explanatory menus and a sealed keypad. The large, two-line (16
characters each) display of disinfectant residual alternates every five
seconds with the pH or fluoride values when the analyzer is set up for two
measurements.
There are two wetside configurations available: Membrane and Bare
Electrode. Both consist of a flow-through cell with a transparent plexiglass
body that houses one or two measuring sensors. The cell’s transparency
permits visual checks on the flow of sample water and measuring condi-
tions. The Membrane wetside can be fitted with any one of four mem-
brane-type sensors (free chlorine, total chlorine, chlorine dioxide or ozone)
for disinfectant measurement. A second sensor can be added for pH or
fluoride measurement. The bare electrode wetside is available for free
chlorine measurement only. This arrangement can be used where a quick
response time is required or if there is a high hardness in the sample water
that could foul a membrane sensor. A second sensor can be added for pH
or fluoride measurement. Note that free chlorine measurement by this
wetside is affected by changes in pH. An optional CO2 gas reagent kit is
available for economical pH adjustment. It is also possible to compensate
for pH changes by using a dual input arrangement with the pH sensor
option for automatically calculating the residual value.
Refer to Table A for part numbers for the various analyzer combinations.

1.3 pH Sensor Kit (AAB5386)
NOTE: When used for pH compensated Free chlorine measurement,
the pH range must be between 6 and 9.
NOTE: Where the standard 1.5-meter sensor cable is not long enough
(for special installations up to 50-meter cable length), an impedance
transformer is used to convert the very high-resistance electrode sig-
nal of the pH to a low-resistance signal. The impedance transformer
(Part No. U95607) is screwed onto the pH sensor cable. The imped-
ance transformer is powered by an integral battery. Battery lifetime
is approximately five years.

system has been properly installed and is in operation.
2.1.2 Check Voltages
The line voltage of the DEPOLOX 3 plus is set at the factory in accordance
with the instructions given at the time of the order (230 V or 115 V).
Check this setting from the rating plate immediately after unpacking the
device, and in any case before it is installed.
If the line voltage setting does not match your supply, the setting will have
to be altered (refer to paragraph 2.1.3, Adjust Line Voltage/Change the
Fuse).
2.1.3 Adjust Line Voltage/Change Fuse
The rating plate on the top of the device shows the line voltage which was
set at the factory. If this does not match the voltage at the site of installa-
tion, the device will have to be adjusted.
NOTE: Operating the device with the wrong voltage can lead to the
device fuse blowing or other damage or malfunction. Adjustment of
the line voltage must take place before installation and before the

connection of cables. The device may be opened and adjusted by an
electrician only.
For connection to power with two hot wires (L1, L2), replace the metal
pin on the F2 socket by a fuse corresponding to the voltage (see Figure
2.1).
The switch to adjust the voltage is inside the housing. To open up the
housing push out the two lateral lugs with a screwdriver or similar tool.
Unscrew the two screws on each side of the cover and lift off the cover of
the housing. Should the ribbon cable be pulled off when doing this, it must
be put back when putting back together. The cables must not be twisted
(if the display is not illuminated the two-core ribbon cable has been in-
serted the wrong way round).
Figure 2.1 - Rating Plate
The change in voltage setting must be marked clearly and permanently on
the rating plate as follows (example):
Line voltage changed to 230 V!
Date .... Name/firm/department
If the device fuse blows repeatedly due to a fault, the device must be
repaired or replaced. Contact USF/W&T Technical Service.
The slide switch to adjust the
voltage allows a choice be-
tween 230 V and 115 V.
When setting to 230 V or 115 V, the fuse must
be changed (fine-wire fuse 5 x 20 mm):
for 230 V: T160mA part no. UXF-92568
for 115 V: T315mA part no. UXJ-92568
