FIELD REPAIRS
Field calibrang or repairs to the ETC control must not be aempted.
Sensors and replacement controls are available through Ranco
wholesalers.
SENSOR MOUNTING
For space sensing, mount the sensor where it will be unaected by
heat/cool discharge or radiated heat sources. Spot sensing requires the
sensor to be in good contact with the surface being sensed. The sensor
can be inserted in a bulb well for immersion sensing.
