(5) Air Cleaner Element Replacement
Safety Precautions
Stopping only the indoor unit is extremely dangerous because the engine
may suddenly start if the customer operates the remote controller on the
indoor unit side. Before carrying out work on the inside of the outdoor unit,
make sure you turn off the power supply circuit breaker of the outdoor unit.
(However, if a system controller or other centralized control device is being
used, an abnormal communications error may be generated.) Alternatively,
perform the STOP operation for the outdoor unit.

Prework check items
1) A dry-type air cleaner element is used. The intake port cover
removes coarse particles. As the intake air is guided into the
body of the air filter, a vortex is created by a cyclone device. The
currents within the vortex cause particles in the air to collect in
a dust cup, while finer particles are filtered out by folded paper
filter elements.
2) If the air cleaner element becomes clogged, the quantity of air
will be reduced, causing the engine to stall.
● Make sure to replace the element periodically.
● Replace the element more frequently in dusty or oily environ
