10. Installation
Choosing the installation location
Installation location requirements
• Air must be distributed optimally.
• The passage of air must not be disturbed.
• Condensation water must be drained easily.
• The support structure must be strong enough to
support the weight of the fan coil unit. (If the structure
is not strong, the fan coil unit may fall off, leading to
personal injury.)
• The ceiling must not be significantly sloped.
• There must be a sufficient space for maintenance and
service.
• The power and communication cables of the fan
coil unit must be at least 1 m away from electronic
appliances such as televisions. (Occasionally, more
distance may be required.)
Reinforcing the ceiling
Make sure that the ceiling is sufficient to support the
weight of the fan coil unit. If dangerous, reinforce the
ceiling with foundation bolts before installing the fan coil
unit.

Optional: Insulating the body of the
fan coil unit
Insulation guide
• For the pipe inlet and outlet and some bent parts, cut
out and shape the insulation material in accordance
with their shape.
• Be sure to insulate the air inlet and outlet (front and
rear) together when insulating the connecting ducts.
Installing the fan coil unit
Preparations for installation
The piping that will be connected to the fan coil unit must
be completed before installation.
1
Check the product to install and its installation
location.
2
Check the following installation requirements:
•
•
When the product is installed on the ceiling, check
the strength of the ceiling first.
When the product is installed on the ceiling, use
the pattern sheet.
• After making the mounting hole on the ceiling,
keep the ceiling surface level.
• You may need to reinforce the ceiling to prevent
the product from causing the upper floor to vibrate.
3
Drill holes on the ceiling or the ceiling support, and
then insert the foundation bolts, as shown in the
following figure:
• Use bolts of Ø 9.52 or M10 size and of 1.5 m or less
length.
•
•
Install at least four foundation bolts so that the fan
coil unit can be fixed firmly.
When the existing ceilings require reinforcement,
use anchor holes.
• For new ceilings, use sunken inserts, sunken
anchors, or other commercially available parts.

CAUTION
• Purchase all the needed parts from the market.
• Because the pattern sheet is made of paper, it may
shrink or stretch slightly due to temperature or
humidity. Therefore, before drilling holes on the
ceiling, be sure to check the correct dimensions.
• Be sure to secure a sufficient space that allows for
access for maintenance or repairs.
