2.2. Choosing the outdoor unit installation location
• Avoidlocationsexposedtodirectsunlightorothersourcesofheat.
• Select a location from which noise emitted by the unit will not inconvenience
neighbors.
• Selectalocationpermittingeasywiringandpipeaccesstothepowersourceand
indoor unit.
• Avoidlocationswherecombustiblegasesmayleak,beproduced,ow,oraccumu-
late.
• Notethatwatermaydrainfromtheunitduringoperation.
• Selectalevellocationthatcanbeartheweightandvibrationoftheunit.
• Avoidlocationswheretheunitcanbe covered by snow. In areaswhereheavy
snow fall is anticipated, special precautions such as raising the installation location
or installing a hood on the air intake must be taken to prevent the snow from
blockingtheairintakeorblowingdirectlyagainstit.Thiscanreducetheairowand
a malfunction may result.
• Avoidlocationsexposedtooil,steam,orsulfuricgas.
• Usethetransportationhandlesoftheoutdoorunittotransporttheunit.Iftheunitis
carriedfromthebottom,handsorngersmaybepinched.

2.4. Constraints on indoor unit installation
You should note that indoor units that can be connected to this outdoor unit have
the following constraints.
•Indoorunitswithmodelintable2canbeconnected.
•Forthenumberofunitsthatcanbeconnected,refertoTable1below.
•Thetotalratedcapacity(cooling)oftheconnectedindoorsunits(refertoTable2)
must not exceed 130% of the outdoor unit capacity (refer to the capacity range of
connected units in Table 1).

Combinations in which the total capacity of indoor units exceeds the capacity of the
outdoor unit will reduce the cooling capacity of each indoor unit below their rated
cooling capacity. Thus, combine indoor units with an outdoor unit within the outdoor
unit’s capacity, if possible.
2.5. Ventilation and service space
Note:
The dimensions given along the arrows above are required to guarantee the
air conditioner’s performance. Install the unit in as wide a place as possible
for later service or repairs.
2.5.1. Windy location installation
When installing the outdoor unit on a rooftop or other location unprotected from the
wind, situate the air outlet of the unit so that it is not directly exposed to strong winds.
Strongwindenteringtheairoutletmayimpedethenormalairowandamalfunction
may result.
The following shows three examples of precautions against strong winds.
1 Face the air outlet towards the nearest available wall about 50 cm (19-11/16")
away from the wall. (Fig. 2-2)
2 Install an optional air guide if the unit is installed in a location where strong winds
from a typhoon, etc. may directly enter the air outlet. (Fig. 2-3)

3 Position the unit so that the air outlet blows perpendicularly to the seasonal wind
direction, if possible. (Fig. 2-4)
