2. Disassemble the control box.
3. Disconnect with the wire (AC1, AC2, AC3, +, - ) to the diode module. (See Fig. 1)
4. Remove the diode module after removing the screw for diode module.
5. Attach the diode module after applying uniformly silicone grease to the back surface of the diode module.

Precautions for Safety
・
Since the following precaution is the important contents for safety, be sure to observe them.
WARNING and CAUTION are described as follows:
WARNING
Indicates an imminently hazardous situation which will result in death or serious injury if proper safety
procedures and instructions are not adhered to.
!
CAUTION
Indicates a potentially hazardous situation which may result in minor or moderate injury if proper safety
procedures and instructions are not adhered to.
!
WARNING
・
Securely exchange the diode module according to this procedure.
If the diode module is incorrectly exchanged, it will cause an electric shock or fire.
・
Be sure to check that the power source for the outdoor unit is turned OFF before exchanging the diode module. The
diode module exchange under current-carrying will cause an electric shock.
・
After finishing the diode module exchange, check that wiring is correctly connected with the diode module before
power distribution. If the diode module is incorrectly exchanged, it will cause an electric shock or fire.
!
CAUTION
・
Band the wiring so as not to tense because it will cause an electric shock.
