Before the calibration, make sure that there is no water pressure in the

5.4.1 Calibration steps
The calibration process involves a few simple steps; the controller will describe the
steps that you need to carry out.
Make sure that you have a bucket of clean tap water to hand.
Navigate the path for the sensor that you want to calibrate.
Calibrate EC sensor: .
Before taking each measurement, rinse the sensor with the clean tap water and dry it
off gently. Blow away any residual moisture.
Make sure to keep stirring the sensor during the wait time. This ensures that the
solution will remain homogeneous.
The measured values are not displayed during the calibration process,
because the values are still fluctuating. A readout will, however, appear in the
step between the two calibration solutions. This readout may differ slightly
from the final value, because the calibration process is not yet complete.
5.5 Pressurizing the NoNa
+
.
To pressurize the NoNa
+
, complete the following steps:
1. Set the pumps to manual mode (see the section "Operating the pumps" on
page 50).
2. Remedy any leaky couplings or other leaks.
The bolts of the CED stack may have come loose during transport. Set a
torque wrench to 9 Nm and use it to check the bolts. Tighten the bolts in the
sequence shown in Figure 5-8.
