• To indicate the direction of refrigerant flow

• To show the installation date

• To mark the brand of the filter dryer

• To indicate the pressure level

What is the primary function of a filter dryer in a refrigeration system?

• To increase the temperature of the refrigerant

• To change the color of the refrigerant

• To filter and dry the refrigerant

• To add refrigerant to the system

What material is used in the solid core of the filter dryer to capture and retain acids?

• Steel

• Copper

• Activated alumina

• Plastic

How does the spring inside the filter dryer function?

• It adds pressure to the system

• It heats the refrigerant

• It keeps the core in a fixed position

• It changes the color of the refrigerant

What is the purpose of the screen at the end of the solid core?

• To add color to the refrigerant

• To capture smaller dirt particles
