When mounting the unit on a wall or the roof, make sure the support is firmly secured so that it cannot move in the
event of intense vibrations or a strong wind.
Do not install the outdoor unit in pits or air vents.

Install the drain fitting and the drain hose (for model with heat pump only)
Condensation is produced when the unit runs, and drains from the outdoor unit when the appliance is operating in the
heating mode. In order not to disturb neighbors and to respect the environment, install a drain fitting and a drain hose to
channel the condensate water.
Install the drain fitting and rubber washer on the outdoor unit chassis and connect a drain hose as shown in the
illustration below.
