After installation work has been completed, explain the “Safety Precautions,” use,
and maintenance of the unit to the customer according to the information in the
Operation Manual and perform the test run to ensure normal operation. Both the
Installation Manual and Operation Manual must be given to the user for keeping.
These manuals must be passed on to subsequent users.

tionislikelytocausedamage.
• When installing the unit ina hospital or communications office, be pre-
pared for noise and electronic interference. Inverters,home appliances,
high-frequencymedicalequipment,and radiocommunicationsequipment
can cause the airconditioner tomalfunction orbreakdown. The aircon
