DO NOT install outdoor unit on top of a building.
If the outdoor unit is installed on a solid surface, such as concrete, use M10 screw bolts and nuts to
secure the unit. Make sure the unit stands erect and level.
If the unit vibrates and generates noise, add rubber cushions between the unit’s feet and the
installation surface.
When the outdoor unit is in heating or defrosting mode, it must drain water. When installing the drain
pipe, plug the accompanied drainage connector to the drainage hole on the chassis of the outdoor unit.
Then, connect the drain hose to the drainage connector. If the drainage connector is used, the outdoor
unit should be at least 4 in (101.6 mm) from the ground.
Plugs and drainage connector are not recommended if there is an electrical heater on the chassis.
Refer to Fig. 2.5 for details.
