For cleaning, use noninflammable and nontoxic cleaning liquid. Use
of inflammable agent may cause explosion or fire.
Ensure an appropriate ventilation, since working in an enclosed
space may increase the risk of deflagration and/or deficiency of
oxygen. Toxic gas may be produced when cleaning agent is heated
to high temperature by, e.g., being exposed to fire.
Cleaning liquid shall be collected after cleaning.
Pay attention not to clamp cables when attaching the service cover to
avoid electric shock or fire.
Keep clearance between the units of more than 50mm, and avoid
obstacles that may hamper air intake, when installing more than one
units together.
Install the outdoor unit in the shade or not exposed to direct sunshine
or direct radiation from high temperature heat source.
Do not install the outdoor unit in a space where a seasonal wind
directly blows to the outdoor fan.
Check to ensure that the foundation is flat, level and sufficiently
strong.
Install the unit in a restricted area not accessible by the general public.
Aluminium fins have very sharp edges. Pay attention to the fins to
avoid injury.
