19. Testing the refrigerant lines for leaks

Checking the refrigerant 

circuit for leaks

R 410A is an air-displacing, non-toxic gas. Uncontrolled release of refrigerant may 

result in breathing difficulties and asphyxiation.

Check the connections for refrigerant leaks:

-  All flared connections on the refrigerant lines between the indoor and outdoor unit.

-  All soldered joints and screw connections on the refrigerant lines in the indoor and 

outdoor unit.
