▪ 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 100mm wide.
NOTICE
The height of the foundation must at least be 150mm from
the floor. In heavy snowfall areas, this height should be
increased up to the average expected snow level,
depending on the installation place and condition.

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

The piping and other pressure-containing parts shall be
suitable for refrigerant. Use phosphoric acid deoxidised
seamless copper for refrigerant piping.
▪ Only use phosphoric acid deoxidised seamless copper.
▪ Foreign materials inside pipes (including oils for fabrication) must
be ≤30mg/10m.
▪ Temper grade: use piping with temper grade in function of the
pipe diameter as listed in table below.
Pipe Ø Temper grade of piping material
≤15.9mm O (annealed)
≥19.1mm 1/2H (half hard)
▪ All piping lengths and distances have been taken into
consideration (see About the piping length in the installer
reference guide).
