7. Indoor Unit Installation
Installation Instructions - Indoor
Unit
PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the label on
the product box to make sure that the model number
of the indoor unit matches the model number of the
outdoor unit.
Step 1: Select installation location
Before installing the indoor unit, you must choose an
appropiate location. The following are standards that
will help you choose an appropriate location for the unit.
Proper installation locations meet the following
standards:
5Good air circulation
5Convenient drainage
5Noise from the unit will not disturb other people
5Firm and solid - the location will not vibrate
5Strong enough to support the weight of the unit
5A location at least one meter from all other
electrical devices (e.g., TV, radio, computer)
DO NOT install unit in the following locations:
Near any source of heat, steam, or combustible
gas
Near ammable items such as curtains or clothing
Near any obstacle that might block air circulation
Near the doorway
In a location subject to direct sunlight
NOTE ABOUT WALL HOLE:
If there is no xed refrigerant piping:
While choosing a location, be aware that you should
leave ample room for a wall hole (see Drill wall hole
for connective piping step) for the signal cable and
refrigerant piping that connect the indoor and outdoor
units. The default position for all piping is the right side
of the indoor unit (while facing the unit). However, the
unit can accomodate piping to both the left and right.
Refer to the following diagram to ensure proper
distance from walls and ceiling:
NOTE:
• If no need the back holder to prop up the
unit:
Finishing the pipe and cable connections before
mount the indoor unit on the wall. If the installation
height is limited, 5cm from the ceiling is allowable,
but this can lower product performance. To ensure
enough space to install and remove the top air lter,
keep at least 10cm or more from the ceiling.
• Need the back holder to prop up the unit:
If connecting pipe and cable with the front panel
open, the minimum distance from ceiling is 22cm
or more, if connecting pipe and cable without front
panel (remove it), the minimum distance from ceiling
is 11cm or more.
Step 2: Attach mounting plate to wall
The mounting plate is the device on which you will
mount the indoor unit.
• Remove the screw that attaches the mounting plate
to the back of the indoor unit.
• Secure the mounting plate to the wall with the screws
provided. Make sure that mounting plate is at against
the wall.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar material, drill
5mm-diameter (0.2in-diameter) holes in the wall and insert
the sleeve anchors provided. Then secure the mounting
plate to the wall by tightening the screws directly into the
clip anchors.
