Installation Precautions
To reduce the risk of serious injury or death, the following installation
precautions 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 to
construct 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 can
cause dripping and water damage to wall and floors.
◦ 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 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 will be in close proximity to a heat source.
◦ where hot/cold air from the outdoors, or a draft from elsewhere (such as air vents, diffusers or
grilles) 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, damage,
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 directly
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 hot spring.
◦ Where dense, salt-laden mist 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 corrosive
gases may be present. If you do, toxic gases can seep into breathable air spaces and can cause
respiratory issues. If the condensate pipe is installed incorrectly, water leakage and damage to the
ceiling, 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 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.
● 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 started
suddenly.
● Remove gas inside the closing pipe when the brazing work is performed. If the brazing filler metal is
melted 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 or
fluorocarbon 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 use
and maintenance of the 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.
