2.3 I Installing the sensors
(pH & pH/ORP, depending on model)
•
Never wipe the sensor using a cloth or paper tissue, as this may damage it.
•
A badly-installed sensor may give false readings and cause inappropriate operation of the appliance.
Neither the manufacturer nor the appliance shall be liable in this event.
•
Carefully unscrew the protection tube from the sensor (
). Keep the protection tube for storing the sensor over
winter.
•
Rinse the end of the sensor with tap water and shake off excess water (
).
•
Loosen the nut fixed to the sensor holder (
)
.
•
Install the pH sensor and/or the ORP sensor (supplied) in the sensor holder so
that the sensor located at the end
of the holder is always submerged in the water flowing through the piping
(
). Ensure that the cable is not
tangled.
•
To avoid damage, sensor end must be located in the center of the pipe, not further.
•
The sensor must always be installed vertically, or where necessary, at a maximum angle of 40°
(
)
.
•
Once the sensor is installed it can be connected to the BNC socket on the control box,
see § “2.5.2. Connecting the
control box” ).
• The sensor must then be calibrated,
see
§ “4.4 I Calibrating the sensors (pH or pH/ORP models)”.
