Mounting the outdoor unit
5.2.1
To provide the installation structure
Make sure the unit is installed level on a sufficiently strong base to
prevent vibration and noise.
NOTICE
▪ When the installation height of the unit needs to be
increased, do NOT use stands to only support the
corners.
▪ Stands under the unit must be at least 100 mm wide.

▪ The height of the foundation must at least be 150 mm from the
floor. In heavy snowfall areas, this height should be increased,
depending on the installation place and condition.
▪ The preferred installation is on a solid longitudinal foundation
(steel beam frame or concrete). The foundation must be larger
than the grey marked area.

▪ Fasten the unit in place using four foundation bolts M12. It is best
to screw in the foundation bolts until their length remains 20 mm
above the foundation surface.

NOTICE
▪ Prepare a water drainage channel around the
foundation to drain waste water from around the unit.
During heating operation and when the outdoor
temperatures are negative, the drained water from the
outdoor unit will freeze up. If the water drainage is not
taken care of, the area around the unit might be very
slippery.
▪ When installed in a corrosive environment, use a nut
with plastic washer (a) to protect the nut tightening part
from rust.

Precautions when making knockout holes:
▪ Avoid damaging the casing.
▪ After making the knockout holes, we recommend you
remove the burrs and paint the edges and areas
around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout
holes, wrap the wiring with protective tape to prevent
damage.
