MAINTENANCE

CAUTION
• Before maintenance, be sure to turn off the circuit
breaker.
• Do not clean the filter with all the hooks of the
center panel disengaged and with only one or two
wires still attached to the center panel. Doing so
may cause the center panel to fall down, possibly
causing injury to any individuals below.
Cleaning of air filter
• If is displayed on the remote controller, maintain the
air filter.
• Clogging of the air filter reduce cooling/heating
performance.
Cleaning of panel and air filter
1. Turn off the air conditioner
• Set the circuit breaker to OFF.
2. Open the center panel
• Loosen the screws on the center panel holders
fixed to the frame covers by turning them about
three times. There is a frame cover on each long
side of the panel.
While removing the center panel, as the panel
moves, the panel pushes the center panel holders
and makes the holders slide.

the center panel upward (1), pull the panel
toward the opening side (2).

both ends, and disengage the opening side hooks
one at a time.
If the center panel holders refuse to slide, loosen
the screws a little more using the screwdriver.
