9.13 Inspection of Wiring Connection
• Refer to the wiring diagram on page 33 and check the connection of each wire.
CAUTION
Secure the wires using clamps to prevent contact with the edges of the structure, etc. Secure the
wires in the same position as prior to removal.
9.14 Inspection of Refrigeration System
• In most cases, the probable cause for insufficient cooling or heating is a clog in the system, a
leakage or an incorrect amount of refrigerant. In such cases, inspect the system according to
the following procedure.
(1) Clogged refrigeration system
• Check the component parts of the refrigeration system, including piping, that could be clogged
with refrigerant. If clogged with refrigerant, only the clogged part is partially frosted. If this occurs,
change the part in question.
(2) Refrigerant leak
• Carefully check all connections, and each component for leaks whenever the refrigeration
system is installed or repaired. Use an electronic gas leak tester to inspect the system. (See "10.
REFRIGERATION SYSTEM REPAIR" section.)
(3) Insufficient refrigerant
• When the unit is not producing sufficient cooling or heating, follow the troubleshooting chart on
page 60 to page 61 to confirm the cause of the problem. Then, charge the system with
refrigerant to the specified amount as indicated on page 95.
