4. When installing a refrigerator with an automatic ice maker, less work is usually required to connect a(n) _____ valve mounted on the water line.

A. automatic expansion
B. saddle
C. T-fitting and shut-off
D. three-way solenoid



Answer :

Final answer:

When installing a refrigerator with an automatic ice maker, a T-fitting and shut-off valve make the process easier and more efficient. Utilizing a pneumatic actuator can enhance reliability and maintenance of the valve. Proper hose connection for uphill water flow improves cooling efficiency in refrigeration systems.


Explanation:

When installing a refrigerator with an automatic ice maker, less work is usually required to connect a T-fitting and shut-off valve mounted on the water line. This setup simplifies the process and reduces the effort needed compared to other options.

Using a pneumatic actuator can be beneficial due to its failsafe action in case of system failure, low maintenance requirements, and high reliability, making it an ideal choice for the valve.

Proper connection of hoses, ensuring water flow uphill from the lower to upper arm of the condenser, is crucial for efficient cooling and system performance in refrigeration setups.
