Selection of installation place
WARNING
• Install the air conditioner securely in a location where the base can sustain the weight adequately.
If the strength is not enough, the unit may fall down resulting in injury.
• Install the air conditioner at a height 8.2' (2.5 m) or more from the floor.
If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous because you
may contact with revolving fan or active electricity.
CAUTION
CAUTION
• Do not install in a location where flammable gas may leaks are possible.
If the gas leak and accumulate around the unit, it may ignite and cause a fire.
Upon approval of the customer, install the air conditioner in a place that satisfies the following
conditions.
• Place where the unit can be installed horizontally.
• Place where a sufficient servicing space can be ensured for safety maintenance and check.
• Place where drained water will not cause any problem.
Avoid installing in the following places.
• Place exposed to air with high salt content (seaside area), or place exposed to large quantities of sulfide gas (hot
spring).
(The unit should be used in these places, special protective measures are needed.)
• A kitchen in restaurant or places around machines and equipment in a factory, where a lot of oils are used.
(Oil adhering to the heat exchanger and the resin parts in the indoor unit may lower the unit performance, splash
water drops, or produce mist and may cause the resin parts to be deformed or damaged.)
• Places where iron or other metal dust is present. If iron or other metal dust adheres to or collects on the interior
of the air conditioner, it may spontaneously combust and start a fire.
• Place where organic solvent is used nearby.
• Place close to a machine generating high frequency.
• Place where the discharged air blows directly into the window of the neighbour house. (Outdoor unit)
• Place where noise of the outdoor unit is easily transmitted.
(When the outdoor unit is installed on the boundary with the neighbour, pay due attention to the level of noise.)
• Place with poor ventilation. (Before air duct work, check whether value of fan speed, static pressure and duct
resistance are correct.)
• Do not use the air conditioner for special purposes such as preserving food, precision instruments, or art objects,
or where breeding animals or growing plants are kept. (This may degrade the quality of preserved materials.)
• Place where any of high-frequency appliances (including inverter devices, private power generators, medical
equipment, and communication equipment) and inverter-type fluorescent light is installed.
(A malfunction of the air conditioner, abnormal control, or problems due to noise to such appliances / equipment
may occur.)
• When the wireless remote control is used in a room equipped with an inverter-type fluorescent light or at a place
exposed to direct sunlight, signals from the remote control may not be received correctly.
• Place where organic solvent is used.
• Place near a door or window exposed to humid outside air (Dew drop may form.).
• Place where special spray is used frequently.
• Place where use a lot of water, such as laundry rooms (This indoor unit is not waterproof.)

Installation space
Ensure there is sufficient space to install the unit and to perform maintenance work as and when required. Keep
0.6" (15 mm) or more for clearance between top plate of the indoor unit and the ceiling surface.
39.4" (1000) or more
39.4" (1000) or more
REQUIREMENT
*1 If there is no ceiling board, the length of the hanging bolt shall be more than 15.7" (400 mm).
*2 Set a service check opening panel at electrical control box side of the unit (size: 17.7" × 17.7" (450 × 450 mm) or more)
for piping, maintenance, and servicing.
*3 For the adjustment of the installation height of the indoor unit.
Selection of installation place
Continual operation of the indoor unit under high-humidity conditions as described below, dew may condense and
water may drop.
Especially, high-humidity atmosphere (dew point temperature: 73°F (23°C) or more) may generate dew inside the
ceiling.
1. Unit is installed inside the ceiling with slated roof.
2. Unit is installed at a location using inside of the ceiling as fresh air intake path.
3. Kitchen
REQUIREMENT
When the humidity inside the ceiling seems to be higher than 80%, attach a heat insulator to the side (top)
surface of the indoor unit. (Use a heat insulator that is 0.4" (10 mm) or more thick.)
