OUNTING
When choosing the installation place please ensure proper space for later calibrations, verification or maintenance service. (see placement on page 32. )
Make sure that the transmitter is protected against overheating that can be caused by direct sunshine.
Assemble the electrode with the instrument prior to the installation.
It is advised to check the operation of the instrument prior to the installation in the control room.
If factory settings need to be modified do it according to the
Programming Description
.
The process connection should be selected according to the type to be installed.
ATTENTION!
When mounting or dismounting the instrument, avoid exposing the electrodes, DO sensors and temperature sensors to mechanical impacts because
these can cause malfunctioning of the unit. The unit should not be loosened if the process is under pressure, in this case user should take care of
depressurization first!
5.1.1.
Installation of pH and ORP electrodes
Prior to mounting into the process the instrument should be put into operation-ready state. For this the user has to insert the electrode (packed separately) into
the instrument as described below:
During this operation be careful not to expose the fragile electrode to mechanical (bending, squeezing, tensile) forces!
The housing of the instrument can be disassembled as described in chapter 4.3.
Remove the plug in the electrode housing from the connector
of the electrode.
Open the box and screw the electrode off the container.
Insert the electrode to its place carefully, screw in with your hand and
using a socket-wrench (size 17) until it reaches the level of the
connector of the temperature sensor (
