Precaution for Safety

The manufacturer shall not assume any liability for the damage caused by not observing the description of this
manual.
DANGER
Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit
breaker to the OFF position. Otherwise, electric shocks may result.
Before opening the intake grille of the indoor unit or service panel or valve cover of the outdoor unit,
set the circuit breaker to the OFF position.
Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with
the interior parts.
Only a qualified installer ( 1) or qualified service person ( 1) is allowed to remove the intake grille of
the indoor unit or service panel of the outdoor unit and do the work required.
Before starting to repair the outdoor unit fan or fan guard, be absolutely sure to set the circuit breaker

the work.
When cleaning the filter or other parts of the indoor unit, set the circuit breaker to OFF without fail, and
place a "Work in progress" sign near the circuit breaker before proceeding with the work.
When you access inside of the service panel to repair electric parts, wait for about five minutes after
turning off the breaker. Do not start repairing immediately. Otherwise you may get electric shock by
touching terminals of high-voltage capacitors. Natural discharge of the capacitor takes about five minutes.

without first conducting these checks.
Even if the circuit breaker has been set to the OFF position before the service panel is removed and
the electrical parts are repaired, you will still risk receiving an electric shock.
For this reason, short-circuit the high-voltage capacitor terminals to discharge the voltage before
proceeding with the repair work.
