unit.
• Make sure that condensation drainage can be conveniently
routed away.
Do not install near a doorway.
• Ensure that the space around the left and right of the unit is
more than "A". The unit should be installed as high on the
wall as possible, allowing a minimum of "B" from ceiling.
• Use a stud finder to locate studs to prevent unnecessary
damage to the wall.
Outdoor unit
• If an awning is built over the unit to prevent direct sunlight
or rain exposure, make sure that heat radiation from the
condenser is not restricted.
• Ensure that the space around the back and sides is more
than 10cm. The front of the unit should have more than
70cm of space.
• Do not place animals and plants in the path of the warm air.
• Take the air conditioner weight into account and select a
place where noise and vibration are minimum.
• Select a place so that the warm air and noise from the air
conditioner do not disturb neighbors.
Rooftop Installations:
• If the outdoor unit is installed on a roof structure, be
sure to level the unit. Ensure the roof structure and
anchoring method are adequate for the unit location.
• Consult local codes regarding rooftop mounting.
