1.3 Warnings
The SPI-C170 is designed and produced with the greatest care. However, you should take into
account that:
- The SPI-C170 makes use of dangerous and harmful chemicals.
- No higher supply voltage than 12VDC is used.
1.4 Background information
After years of collaboration with a team of specialists in the field of water treatment, the SPI
measure and control system was introduced. The SPI-C170 is the fourth generation of its kind. The
SPI-C170 is a water control system based on the colorimetric measuring method that utilizes
reagents colour discoloration. The intensity of the discoloration after a measurement with the
reagent is a measurement of the quantity of Chlorine in the water. The greatest advantage of
colorimetric measuring is that it is not affected by external factors like pH and flow.
1.5 Conditions of use
 Surroundings free of aggressive vapours
 Temperature of the room housing the SPI-C170 is between 5C - 40C
 Relative humidity not > 80%
 No condensation

2. Description and operation
2.1 Description of the SPI-C170
The SPI-C170 is supplied and preassembled on one assembly plate provided with:
 1 Control-unit
 1 Analysis-unit
Dimensions (L x W x H) = 480 x 480 x 100 mm
All parts are installed either water technical or electro technical. See figure 2.1.1.
2.2 Operation of the SPI-C170
The sample water is fed into the buffer jar. The buffer serves, as the name implies, as a buffer from
where the water can flow to the measuring cell. The surplus water will flow back to the pool’s buffer
system. The SPI-C170 will run the measurements of the water within a freely adjustable time. See
figure 2.2.1.
The measuring cycle of the SPI-C170 is as following:
 Empty cell of previous measurement
 Fill cell with the sample water and empty once more (rinse)
 Fill cell with to be measured water and start measuring the zero value and empty again
 Provide a shot of reagent, and fill the cell with a limited supply of water, measure the
discoloration
 Fill the cell with some extra water and measure the discoloration again (2nd measurement to
check the saturation of the reagent, and to adapt the reagent valve time to save reagent), then
empty cell
 Fill cell with the to be measured water and empty once more (rinse)
 Fill cell fully with water
The drain valve empties the cell after every step. That water exiting the cell is led to the sewer.
2.3 Software structure of the SPI-C170
The SPI-C170 makes use of simple operating software. The complete operation is executed using the
buttons on the unit. The display shows measured values and settings. The hardware features an
internal memory wherein data, reports, and calibration settings are stored. This data is available on
demand and provided with a date and time of occurrence. When you have the optional SPI-REMOTE
software, it is possible control and see the information of the SPI using the network or internet. With
the optional SPI-GRAPHS software, you can use the data downloaded with the remote software, and
use this for data acquisition.

3. Safety
3.1 Safety regulations
The SPI-C170 is as careful as possible designed with the eye on safety. We tried to reduce the safety
risks to a minimum.
 The SPI-unit is supplied with a 12VDC adapter via a power outlet.
 While the SPI-unit and the analysis-unit are placed next to each other, the water is not
interfering with the electrical systems.
 Using the remote software (optional) you can use our services to provide assistance over
distance
3.2 Risks
We would like to appoint the remaining risks. You need to handle these carefully by fully instructed
and authorized staff:
 Refilling the reagent
 Cleaning spilled compound
 Store reagent in a cool, dark environment, provided with instructions.
 Keep the SPI-unit and the analysis-unit clean from any remaining reagent, because this will
create stains with time.
3.3 Personal protective equipment
 Wear while in direct contact with the reagent safety glasses, latex gloves and protective clothing.
3.4 R-S sentences
 Reagents colour R36/37/38
Harmful to the eyes, respiratory system and skin.
R25
Causes severe burns.
S2
Keep out of reach from children.
S20
Do not eat or drink.
S24/25
Avoid contact with the skin and eyes.
S45
In case of accidents, immediately seek professional help.

4. Transport and storage
4.1 Disassembly
To disassemble the SPI-C170, follow the following procedure:
1. Remove the adapter from the power outlet so that the unit is powerless.
2. Remove the reagent vial from the holder (watch out for spilling reagent from the tube).
3. Empty the reagent vial, and seal it with the cap.
4. Empty the buffer jar using the drain tap.
5. Remove possible pH electrodes and store these for later use (don’t forget the protective cap with
KCl-solution).
6. Flush the valves with clean water or when possible, distilled water. Do this by filling the buffer jar
with this. Especially the reagent valve needs extensive cleaning. The reagent will cristalize when
it dries. Do this by replacing the reagent vial with a container of clean water. Now control the
valves a few times. See chapter 10.1.4.3 Times & test, and for the reagent valve chapter 10.1.4.2.
7. Flush the analysis-unit well with clean water, then make sure the unit is empty and dry.
8. Clean all tubes with clean water and dry.
9. Remove all inserted cables from the SPI-unit.
10. Before the taking the assembly plate off the wall we point out once more that all parts should be
dry.
11. Take the SPI-unit off the wall.
4.2 Transport
1. After disassembly, make sure the SPI-unit is placed in a firm box, with the components facing
upwards. This may also be standing upward.
2. Protect the corners well from impacts.
3. Cover the upward facing components with filling or air foil.
4. Close the box with tape.
5. Make sure the box remains free from damage.
4.3 Storage
While storing make sure the environment meets the following requirements:
 Moisture free
 Free of corrosive vapours
 Temperature between 5C - 40C

10.Calibration
All measurements connected to the SPI-C170 must be regularly checked and, if necessary, be
calibrated. This ensures the quality of the measurements made. You can enter this menu by selecting
Calibration from the main menu.
Calibrating the measurements is done by using calibrated third party equipment. The following
measurements can be calibrated on the SPI-C170 Chlorine:
 Chlorine
 pH
See figure 10.1.
Figure 10.1.
10.1 Chlorine
At the procedure of calibrating Chlorine you are able to choose between 2 different methods of
calibration:
 With handmeter (a relatively fast method to calibrate Chlorine measurement using a
handmeter)
 With fluids ( a method to calibrate the Chlorine measurement using professional calibration
fluids)
Next to calibrating you can also choose for:
 Restore calibration (restores the calibration settings to the factory settings)
 Settings (various settings for controlling the valve times, checking the current cell values and
refilling the reagent vial)
See figure 10.1.1.

10.1.1 Calibrating with handmeter
When you select Calibrating with handmeter the menu as in figure 10.1.1.1 will appear. Here you can
perform a calibration using a third party handmeter. Now perform the following instructions:
1 Take a sample from the drain tap under the buffer jar and measure this with the handmeter.
Refer to the handmeter’s instructions here.
2 Compare the value of Current with the measurement of the handmeter.
If there is a big difference between the current and metered values, press enter ( ).
3 You now get to see the Adjust Value screen where you must enter the correct metered value
at Set
4 Press the tick () now.
5 The measurement has been calibrated.
Start calibrating the measurement only after at least one measurement has been
performed. Otherwise this could cause a wrong calibration.

10.1.2 Calibrating with fluids
Calibrating using fluids guarantees a more dependable calibration then when using a handmeter. The
system lets you first perform a zero point measurement, and after that a measurement using a
control fluid of your choice. The measurement will then be calibrated at 2 points.
To calibrate with fluids, select
calibrating with fluids, the menu as in figure 10.1.2.1 will appear.
Figure 10.1.2.1
Follow the following steps to calibrate with fluids:
1 Make sure you have the correct control fluids and tools within reach. Here we will use a
control fluid of 0.52 mg/l.
Select the line Cal at … mg/l and press enter ( ). Fill in the value of your control fluid in mg/l, and
confirm with the tick ().
Now select Begin 0 mg/l calibration and press enter ( ). The menu of figure 10.1.2.2 now appears.
Figure 10.1.2.2.
When you scroll down you have free use of the valves. Just select and press enter ( ). Use the
supply valve to fill the cell with water.
Now select Remeasure and press enter ( ). The actual value now needs to show between 980
and 1015 millivolt (mV).
