6  BEFORE INSTALLATION 
6.1  General Warnings 
1.  Do  not  separate  the  Hydran  201Ti  Intelligent  Transmitters  from  their  respective 
Hydran 201 sensor.  The H201Ti is set at the factory for a specific H201 sensor.  To 
verify  whether  the  two  components  are  paired  correctly,  consult  the  serial 
numbers  indicated  on  the  shipping  box  and/or  the  Test  Certificate  and  Data 
Sheet.  The sensor’s serial number is located below the connector (see Figure 3-3); 
while the H201Ti’s serial number is located at the back of the heating plate (see 
Figure 6-1 below).

2.  Do  not  remove  the  protective  plastic  caps  from  the  sensor  and/or  the  brass 
adaptor’s  threaded  extremity  until  ready  to  install  on  the  transformer  valve.  
These  caps  protect  the  adaptor  threads  (see  Figure  6-1  above)  and  the  sensor 
membrane  from  debris  and  sharp  objects.    If  the  sensor  is  dismounted,  place 
immediately the supplied cap onto the sensor’s threads.
