Indoor Unit Installation
Proper installation locations should
meet the following standards:
The location meets the clearance
requirements specified on the next page for
the installation and maintenance of the
unit.
There is enough room for the refrigerant
piping and condensate drain pipe.
The ceiling is horizontal/level and its
structure can support the weight of the
unit.
The air inlet and outlet will not be blocked.
Cassette airflow will fill the entire room.
There is no direct radiation from heaters.
Lift unit using
these brackets
DO NOT install the indoor unit in any of the
following locations:
Areas with oil drilling or fracking.
Areas that experience electrical power
fluctuations, such as factories.
Enclosed spaces, such as cabinets.
Kitchens that use natural gas.
Areas with strong electromagnetic waves.
Areas where flammable gas or materials
are stored.
Rooms with high humidity, such as
bathrooms or laundry rooms.
PRIOR TO INSTALLATION
• Determine the best prearranged route in
which to move the unit to the installation
site as it will be heavy.
• Unpack and unseal the unit from its
packaging. Then, lift and move the unit
using the base of the 4 brackets (2 per side)
shown in Fig. 5.1 below.
NOTE: Avoid lifting or exerting force on any
other parts of the unit (especially any of the
refrigerant piping, water discharge piping, or
plastic parts as these could get damaged).
Step 1: Select an installation location
Before installing the indoor unit, you must choose
an appropriate installation location. The ceiling
cassette is designed to fit and mount between two
ceiling joists that are 16 inches apart (on-center)
from one another. If this unit is to be installed in a
room that has a finished ceiling, the steps on the
following pages of this section will require you to
locate the joists and cut a large hole in the ceiling
(using the included cardboard template as a guide)
between them. You will also be required to drill a
hole in the wall for refrigerant piping and wiring to
run through to the exterior of the house to be
connected to the outside unit. Please carefully
read the entire manual and refer to the
guidelines and illustrations on this page to
help you determine an appropriate location
and plan your installation before proceeding.
