When installing a new thermostat, what should be checked regarding the capillary tube?

The correct answer involves ensuring that the capillary tube is not routed near any electrical connections. This is essential because proximity to electrical connections can lead to issues such as electromagnetic interference, which may affect the accuracy and operation of the thermostat. Furthermore, being near electrical connections can pose risks of damage due to heat generated or accidental contact, leading to potential failures or safety hazards.

While it is also important to ensure that the capillary tube is free of kinks, checking for leaks, and verifying its size, these factors generally focus on the overall integrity and functionality of the capillary tube itself rather than its placement relative to other components. Routing the capillary tube away from electrical connections is a preventative measure that helps maintain the thermostat's accuracy and ensures safe operation. Thus, understanding the importance of proper placement helps ensure reliability and safety in the system.
