• When you install the outdoor unit in high places such as a roof,
install fence or guardrail around it. When there is no fence or
guardrail, service person could fall.
• Do not install the product in places where corrosive gases such
as sulfur oxides, ammonia, and sulfurous gas are produced. (e.g.
Toilet outlet, ventilation opening, sewage works, dyeing complex,
cattle shed, sulfuric hot spring, nuclear power plant, ship etc.)
When installing the product in those places, contact an installation
specialty store as the copper pipe and brazing part will need
additional corrosion proof or anti-rust additive to prevent corrosion.
• Make sure not to keep any inflammable materials (such as
wooden materials, oil etc.) around the outdoor unit. When
there’s fire, those inflammable material will easily catch the
fire and may pass it on to the product.
• Depending on the condition of power supply, unstable power or
voltage any cause malfunction of the parts or control system. (At
the ship or places using power supply from electric generator...etc)
• Make sure to install MCU when using HR products.
• When you select the location to install the MCU, the location is
far away from indoor rooms because the refrigerant running of
MCU may create noise.
Outdoor unit space requirements
• Space requirement was decided based on following conditions;
Cooling mode, outdoor temperature of 35 °C. Larger space is
required if the outdoor temperature is higher than 35 °C or if
the place is heated easily by quantity of solar radiation.
• When you secure installation space, consider path for people
and the direction of the wind.
• Secure installation space as shown in the below illustration,
considering ventilation and the service space.
• If the installation space is narrow, installer or other worker may get
injured during work and may also cause problem to the product.
• If you install multiple number of outdoor units in one space,
make sure to secure enough ventilation space if there’s any
walls around the product that may disturb the air flow. If enough
ventilation space is not secured, product may malfunction.
• You may install the outdoor units with 20mm of space
between the product, but product’s performance may decrease
depending on the installation environment.

• For <Case 1> or <Case 3>
– Height of the wall on the front side should not be higher
than 1500mm.
– Height of the wall on the air inlet side should not be higher
than 500mm.
– Height of the wall on the side is not limited.
– If the height of the wall exceeds by certain value (h1, h2),
additional clearance [(h1)/2, (h2)/2 : Half of the exceeded
height] should be added to the service space (S1, S2).
