Issue:
What is the sensor depth?
Resolution:
If sensors need to be replaced and new sensors are available: the new sensor can be taped/strapped on to the existing refrigerant lines and connected to the chiller controls. Pumpdown then may be initiated using the external sensors for control. This is only for help in speeding up the refrigerant handling process and is not recommended for permanent installation.
Once the chiller has been pumped down, perform standard refrigeration recovery practices. Remove and replace the sensors, set to the correct sensor depth.

Sensors are direct immersion type...in the refrigerant/oil.
