Provide more space around the air intake than shown in the examples if the ambient temperature
exceeds 95 °F DB (35 °C DB) or if the thermal load of all of the outdoor units exceeds the capacity.
Consider the transportation route, installation space, maintenance space, and access, and install ●
the unit in a location with sufficient space for the refrigerant piping.
Observe the installation space specifications that are shown in the figures. ●
Provide the same space for the air intake at the rear of the outdoor unit.
