8.14 Inspection
• In most cases, the probable cause for insufficient cooling is a clogged system, leakage or an
incorrect amount of refrigerant. In such cases, inspect the system according to the following
procedure.
(1) Inspection of clogged system
• Check the component parts of the refrigerant system, including piping, that could be clogged
with refrigerant. If clogged with refrigerant, only the clogged part is frosted partially. In such a
case, change the part in question.
(2) Inspection of refrigerant leak
• Carefully check all connections, and each component for leaks whenever the refrigerant system
is installed or repaired. Use an electronic gas leak tester to inspect the system.
(3) Insufficient refrigerant
• In case the unit is judged to be deficient in cooling capacity, make sure to perform the inspections
in 64. 9.1 (1) and 64. 9.1 (2) to confirm the cause of trouble. Then, charge the system with
refrigerant to the specified amount.
