points before requesting service. If it still does not work properly,
contact your dealer or service center.

OPERATING RANGE

The air conditioner is operable within the temperature ranges as
listed below:

WIRED REMOTE CONTROLLER

A separately sold wired remote controller (STK-RCS-
7TWSUA) used with this air conditioner is also available. If
you wish to use the wired remote control function, you will
need to purchase both the optional wired remote controller
and its connection kit (STK-KCW2).

Trouble Possible

5. Thermostat is set

too high for
cooling.

5. Set the

Clicking sound is
heard from the air
conditioner.

In cooling operation,
any plastic parts may

change. In this event,
a clicking sound may
occur.

This is normal, and
the sound will soon
