SM-16005-rev.2 vInstallation PrecautionsTo reduce the risk of serious injury or death, the following installationprecautions must be followed.● When installing the unit into…◦ A wall: Make sure the wall is strong enough to hold the unit’s weight. It may be necessary toconstruct a strong wood or metal frame to provide added support.◦ A room: Properly insulate any refrigerant tubing run inside a room to prevent “sweating” that cancause dripping and water damage to wall and floors.◦ Damp or uneven areas: Use a raised concrete pad or concrete blocks to provide a solid, levelfoundation 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 wind baffle.◦ A snowy area: Install the outdoor unit on a raised platform that is higher than drifting snow.Provide snow protection hood.● If the remote sensors are not used with this controller, then do not install this controller…◦ in a room where there is no thermostat.◦ where the unit is exposed to direct sunshine or direct light.◦ where the unit is in close proximity to a heat source.◦ where hot/cold air from the outdoors, or a draft from elsewhere (such as air vents, diffusers orgrilles) can affect air circulation.◦ in areas with poor air circulation and ventilation.● 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 fire, oil, steam, or powder can directly enter the unit, such as in close proximity or directlyabove 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 hottub or 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 condensate pipe for the indoor unit near any sanitary sewers where corrosivegases may be present. If you do, toxic gases can seep into breathable air spaces and can causerespiratory injuries. If the condensate pipe is installed incorrectly, water leakage and damage to theceiling, floor, furniture, or other possessions may result. If condensate piping becomes clogged,moisture can back up and can drip from the indoor unit. Do not install the indoor unit where suchdripping can cause moisture damage or uneven locations: Use a raised concrete pad or concreteblocks to provide a solid, level foundation for the unit to prevent water damage and abnormalvibration.● Before performing any brazing work, be sure that there are no flammable materials or open flamesnearby.● Perform a test run to ensure normal operation. Safety guards, shields, barriers, covers, and protectivedevices must be in place while the compressor/unit is operating. During the test run, keep fingers andclothing away from any moving parts.● Clean up the site when finished, remembering to check that no metal scraps or bits of wiring havebeen left inside the unit being installed.● During transportation, do not allow the backrest of the forklift make contact with the unit, otherwise,it may cause damage to the heat exchanger and also may cause injury when stopped or startedsuddenly.● Remove gas inside the closing pipe when the brazing work is performed. If the brazing filler metal ismelted with remaining gas inside, the pipes will be blown off and it may cause injury.● Be sure to use nitrogen gas for an airtight test. If other gases such as oxygen gas, acetylene gas orfluorocarbon gas are accidentally used, it may cause explosion or gas intoxication.After installation work for the system has been completed, explain the “Safety Precautions,” the proper useand maintenance of the unit to the customer according to the information in all manuals that came with thesystem. All manuals and warranty information must be given to the user or left near the Indoor Unit.
