Johnson Controls (H,Y,C)IDM012B21S Installation And Maintenance Manual page 7

▫ Damp or uneven areas: Use a raised concrete pad or concrete blocks to provide a solid, level
foundation for the unit to prevent water damage and abnormal vibration.
▫ An area with high winds: Securely anchor the outdoor unit down with bolts and a metal frame.
Provide a suitable air baffle.
▫ A snowy area: Install the outdoor unit on a raised platform that is higher than drifting snow. Provide
snow vents.
● Do not install the unit in the following places. Doing so can result in an explosion, fire, deformation,
corrosion, or product failure.
▫ Explosive or flammable atmosphere
▫ Where a fire, oil, steam or powder can directly enter the unit, such as nearby or above a kitchen
stove.
▫ Where oil (including machinery oil) may be present.
▫ Where corrosive gases such as chlorine, bromine, or sulfide can accumulate, such as near a hot
tub or a hot spring.
▫ Where dense, salt-laden airflow is heavy, such as in coastal regions.
▫ Where the air quality is of high acidity.
▫ Where harmful gases can be generated from decomposition.
● Do not position the drain pipe for the indoor unit near any sanitary sewers where corrosive gases
may be present. If you do, toxic gases can seep into breathable air spaces and can cause respiratory
injuries. If the drain pipe is installed incorrectly, water leakage and damage to the ceiling, floor,
furniture, or other possessions may result. If the drain pipe becomes clogged, water may drip from the
indoor unit. Do not install the indoor unit where such dripping can cause moisture damage or uneven
locations: Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the unit
to prevent water damage and abnormal vibration.
● Before performing any brazing work, be sure that there are no flammable materials or open flames
nearby.
● Perform a test run to ensure normal operation. Safety guards, shields, barriers, covers, and protective
devices must be in place while the compressor/unit is operating. During the test run, keep fingers and
clothing away from any moving parts.
● Clean up the site when finished, remembering to check that no metal scraps or bits of wiring have
been left inside the unit being installed.
After installation work for the system has been completed, explain the "Safety Precautions," the proper use
and maintenance of this unit to the customer according to the information in all manuals that came with the
system. All manuals and warranty information must be given to the user or left near the Indoor Unit.
