Cautions for Safety
Always use a dedicated circuit and install a ground
fault interrupter.
Incorrect electrical work may lead to
current leak and fire or electrical shock.
Wiring work should conform to the
installation instructions.
Electrical wiring should use the specified cable
and to be properly secured.
When the specified cable is not used, or
connection or securing is incomplete,
electrical resistance becomes larger and
may cause abnormal heating or fire.
Use the specified cable and properly
secure it on an appropriate location.
Do not change the set values of the safety device.
Using the refrigeration unit with changed
values may cause failure of the safety stop
function and lead to a burst or fire.
Do not change the set values of the
safety device. If they are changed
unintentionally, shut off the power switch
and ground fault interrupter and consult
with the distributor.
When the ground fault interrupter activates, report
to the specialty company.
Forced recovery of power may cause
current leak, leading to fire or electrical
shock.
For the purpose of controlling concentration of
refrigerant gas, install a leak detector and
mechanical ventilation equipment in the
refrigerant-handling facility (inside the room).
Refrigerant gas leak may cause suffocation.
Electrical Work
Grounding Work
Securely place the cover on the electrical box and
enclosure panel.
Cautions for Use
Do not insert a finger, stick or foreign object into
the ventilation opening and fan guard of the
enclosure panel.
When water or other material gets into the
electrical box, turn off the power switch and shut
off the ground fault interrupter.
Be sure to comply with the following
Lack of grounding work may lead to
electrical shock caused by current leak.
Securely carry out grounding work by
qualified technicians.
Incomplete attachment may lead to
penetration of water and living creatures,
thereby causing current leak and
fire/electrical shock.
Confirm that covers are securely
installed.
Such object may hit the fast rotating fan
and result in injury.
Continued use may cause short-circuit,
leading to fire or electrical shock.
Do not splash water on electrical
components or wash them with water.
