For connections other than those specified below, consult your dealer.
Number of connecting
SVZ-series unit
Any indoor units other than SVZ-series units are not

connectable.
• The total rated capacity (cooling) should be 100% or
1 below including the SVZ-series unit (only SM60).
• Only 1 SEZ or 1 PEAD can be included in the connection.
*4 A Branch box can connect to maximum 3 of the SEZ/PEAD-series units.
*5 A Branch box can connect to maximum 2 of the SEZ/PEAD-series units.
When connecting with 1 and over 1 of the SEZ/PEAD-series units, the total
rated capacity (cooling) including of the SEZ/PEAD is 100% and below 100%

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 airflow and a malfunction
may result.
The following shows 3 examples of precautions against strong winds.
1 Face the air outlet towards the nearest available wall about 20" (500 mm) away
from the wall. (Fig. 2-2)
2 Install an optional wind baffle if the unit is installed in a location where strong
winds from a typhoon, etc. may directly enter the air outlet. (Fig. 2-3)
A Wind baffle
3 Position the unit so that the air outlet blows perpendicularly to the seasonal wind
direction, if possible. (Fig. 2-4)
