Caution
Removing electrical components
Remove the cover screws before removing an electrical component.
Not doing so may damage the refrigerant pipe.
Replace the grease on the heat sink with new grease.
Not doing so may cause the PCB to fail due to insufficient cooling.
Removal
Caution
Do not touch the hatched area.
Always replace the grease after removing an electrical component.
Mounting
Caution
Do not touch the hatched area when mounting the refrigerant pipe.
Service port
When using the service port, do not let the electrical components come into contact with
refrigerant or oil.
Electrical work
Install an earth leakage breaker resistant to high-frequency electrical noise.
(Since this product contains an inverter device, this is necessary in order to prevent a
malfunction of the breaker itself.)
Make sure to establish an earth connection.
