1. When chased laying is carried out of refrigerant pipings, take care to seal the ends of these
refrigerant lines, by pinching and welding them so as to protect them from infiltrations.
2. Check if chosen pipings have such diameters and features (copper thickness) as to be suitable to
Units which belong to system to R410A refrigerant.
Finishing of installation: strictly tape insulating
material that wraps refrigerant pipings, by
proceeding from the bottom upwards.
Cover the pipings with closed cells’ insulation
material, resistant to temperatures of at least
120°C. It is important that there is no air pocket
between insulating material and the material
which wraps refrigerant pipings.
1. If there is the risk that Outdoor Unit may fall down or overturn, it is advised to install tie rods in
addition to anchor bolts (4 x Ø8mm, or 4 x Ø10mm) on Outdoor Unit’s base.
2. The installation of a raised bearing bed as regards ground prevents snow from piling up around
Outdoor Unit, and at the same time it makes easier condensate and defrosting water drainage.
3. Take care to fix Outdoor Unit perfectly horizontally.
NOTE: at least 2 sides
that are indicated in the
Figure by “L1”, “L2” and
“L3” must be kept free
from obstacles.
