Any presence of foreign substance such as air can cause
abnormal pressure rise or explosion.
CAUTION
Properly ground the unit.
Do not connect the grounding wire to a gas pipe, water pipe,
lightning rod, or grounding wire from a telephone pole. Im-
proper grounding may result in electric shock, smoke, fire,
and/or malfunction due to noise interference.
Do not put tension on the power supply wires.
If tension is put on the wires, they may break and result in
excessive heat, smoke, and/or fire.
Install an earth leakage breaker to avoid the risk of elec-
tric shock.
Failure to install an earth leakage breaker may result in
electric shock, smoke, and/or fire.
Use the kind of power supply wires that are specified in
the installation manual.
The use of wrong kind of power supply wires may result in
current leak, electric shock, and/or fire.
Use breakers and fuses (current breaker, remote switch
< Type-B fuse>, moulded case circuit breaker)
with the proper current capacity.
The use of wrong capacity fuses, steel wires, or copper
wires may result in malfunctions, smoke, and/or fire.
