Selection of installation place
Avoid installation in the following kinds of locations.
• Dx-coil interface is recommended to be installed indoors. Install it in a location where there is
no rain, wind, and direct sunlight.
• Do not install in locations where there is a machine generating high frequency. Failure to do
so may cause a wrong operation or an abnormality.
• Do not install in locations with atmospheres with mist of oil (including machine oil) or dense
vapor, or locations containing salt such as the coast area, or locations with acidic or alkaline
atmospheres, or locations where sulfurizing gas are generated such as areas with hot
springs. Use in inappropriate locations result in malfunctions.
• Do not put any vessel contains the water in the vicinity of the indoor unit (including Dx-coil
controller, Dx-valve kit).
If the water spills and enters into the inside of the unit, the electric insulation deteriorates and
may result in an electric shock.
• Make sure that the air filter is attached on the indoor unit. If it is not, the dust clogs in the
heat exchanger etc. in the air conditioner and may result in water leakage or defrosting.
• Separate the television or radio from the air conditioner or remote controller at least 3'3 "(1m)
Failure to do so may cause the disturbance of the image, or the noise.
• Do not use for special-purpose (Foods, animals and plants, precision machine, storage of
the artwork etc.).
• Do not use in locations where there is anything that would be compromised by wetness.
The mist or water dew drop may result in damage.
• Do not install in locations where organic solvents are being used.
• Do not install in locations near doors or windows where the air conditioner may come into
contact with high humidity outside air. Condensation may occur as a result.
• Do not install in locations where special sprays are used frequently. The location has an
impact on the insulation of the equipment and may cause the ignition.
• Do not install in locations with high-humidity atmosphere. Doing so may cause condensation
of the equipment, splashing of water from the air outlet side of indoor unit.
Ex. 1) Installation to inside of the ceiling where is high humidity.
2) Installation to inside of the ceiling used for the path of the fresh air intake.
3) Installation to a kitchen.
• In the above cases, additionally attach the heat insulator (grass wool etc.) to all positions of
the air conditioner, which come to contact with the high-humidity atmosphere.
* The guideline of the high-humidity condition is "dew-point temperature: 73°F (23°C) or
higher", however, the decision should be made according to the trial operation conducted
in each installation location.
• Install in locations that ensure the sufficient space needed for the service so that the
equipment does not come to contact with the surface of the wall or the ceiling.
• Fix the Dx-coil controller, Dx-valve kit to the stable surface. Failure to do so may cause the
vibration or the noise.
• Do not install the Dx-coil controller, Dx-valve kit to the locations where there is a temperature
difference with the ambient temperature. Failure to do so may result in condensation, rust, or
malfunction. Ex. The sheet metal side surface of the AHU outlet.
• Install the Dx-valve kit to where the noise is no problem due to the Dx-valve kit makes
the refrigerant noise. Also, it may make the refrigerant noise when other indoor units are
operating even if the AHU is stopping like defrosting.
• Do not install in locations with the high temperature or the high-humidity atmosphere of
126°F (52°C) or more / RH 80% or more. Also, do not install it in a place where dew
condensation occurs inside the Dx-coil controller.
• When installing the Dx-valve kit and the Dx-coil controller into the Air handling unit, do not
install it where it is exposed to the cooled air of the secondary side of the heat exchanger.
• Do not install in locations where iron or other metal dust is present. If iron or other metal
dust adheres to or collects on the interior of the Dx-coil controller, it may spontaneously
combusted and start a fire.
