(2) Install a canvass duct to the air discharge outlet and air inlet so that
vibration from the machine body isn't transmitted to the duct or ceiling.
You should also apply acoustic (insulation material) to the inside of
the duct, and vibration insulation rubber to the suspension bolts.
(3) Install suspension bolts.
(Use bolts of 10 mm diameter.)
• Install the equipment where supporting structures are strong
enough to bear the equipment's weight. Use embedded inserts or
anchor bolts with new buildings and hole-in-anchors with old build-
ings.
5. INDOOR UNIT INSTALLATION
〈〈 〈〈 〈〈 〈〈When installing optional accessories, read also the installation manual for optional accessories.
Depending on the field conditions, it may be easier to install optional accessories before the indoor
unit is installed.〉〉 〉〉 〉〉 〉〉
(1) Fix the hanger bracket to the suspension bolt. Tighten both upper
and lower nuts firmly using washers.
(2) Adjust the height of the unit.
(3) Make sure the unit is level.
• Level the unit with a level when installing. If the unit is not level, it
could become the source of water leaks.
• When leveling the unit, check all four corners with a level or a vinyl
tube containing water. (See the figure on the right.)
(4) Tighten the nuts on the top.
(5) Insulate the two hanger brackets on the discharge side with the attached sealing pad. (× 2) Insulate the
edges so that the surface and edges of the hanger brackets cannot be seen. (CS-200 · 250EMHPK)
