3 Selection of installation place
Upon customer’s approval, install the air conditioner in a place which satisfies the following conditions:
Place where it can be installed horizontally.
Place which can reserve a sufficient service space for safe maintenance or checks.
Place where there is no problem even if the drained water overflows.
Avoid the following places:
Salty places (seaside area) or places with much gas sulfide (hot spring area) (If selecting such a place, special
maintenance is required.)
Places where oil (including machine oil), steam, oil smoke or corrosive gas is generated.
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.
Places where an organic solvent is used.
Chemical plants with a cooling system using liquid carbon dioxide.
Places where a device generating high frequency (inverter, non-utility generator, medical apparatus, or
communication equipment) is set. (Malfunction or abnormal control of the air conditioner, or interference to
devices listed above may occur.)
Places where discharged air from the outdoor unit blows against the windows of a neighbour’s house.
Places unable to bear the weight of the unit.
Places with poor ventilation.
The cooling performance may decline considerably when total operating capacity of cooling indoor units is less
than 4 HP while ambient temperature is below 0 °C.
