INSTALLATION SPACE

● The installation space shown in the following examples is based on an ambient temperature under
cooling operation of 35 °C DB at the air intake of the outdoor unit.
Provide more space around the air intake than shown in the examples if the ambient temperature
exceeds 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.
If the installation is not performed according to the specifications, it could cause a short circuit and
result in a lack of operating performance.
As a result, the outdoor unit might easily be stopped by high-pressure protection.
