INSTALLATION REQUIREMENTS
Review the following information before installing the unit:
•
Do not
install the indoor units near a direct source of heat such as
direct sunlight or a heating appliance.
• Allow sufficient space for airflow and unit servicing. See Fig. 5 — on
page 6 for the minimum required distances between the unit and the
walls or ceilings.
• Communication wiring must be at least 3 ft. (1m) away from all
electromagnetic interference (televisions, radios, etc.) sources.
Interference is still possible even if this distance is maintained.
• Ensure any hanger used is strong enough to withstand the unit’s
weight.
• If the indoor unit is installed in an unconditioned space, running for
long periods of time when the temperatures are outside the
recommended indoor unit operation ranges, it is recommended that the
installer seal all corners of the indoor unit to prevent any leaks and add
insulation material (13/32 to 13/16 in (10-20 mm)) to the entire surface
of the indoor unit to avoid condensation or heat transfer.
NOTE: Nuisance sweating may occur if the unit is installed in a high
humidity environment with low airflow.
