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
appropriate location. The following are standards that will help
you choose an appropriate location for the unit.
Proper installation locations meet the
following standards:
✓Good air circulation
✓Convenient drainage
✓Noise from the unit will not disturb other people
✓Firm and solid — the location will not vibrate
✓Strong enough to support the weight of the unit
✓A location at least one meter from all other electrical
devices (e.g. TV, radio, computer)
DO NOT install unit in the following locations:
✕Near an obstacle that will block air inlets and outlets.
✕Near any obstacle that might block air circulation
✕Near the doorway
✕In a location subject to direct sunlight
Note about wall hole
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 and power 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 accommodate piping to both the left
and right.

Kaden Installation Manual | 11
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 flat against
the wall.
Note for concrete or brick walls
If the wall is made of brick, concrete, or similar material,
drill 5mm 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.
Step 3: Drill wall hole for connective piping
You must drill a hole in the wall for refrigerant piping, the
drainage pipe, and the signal cable that will connect the indoor
and outdoor units.
1. Determine the location of the wall hole based on the
position of the mounting plate. Refer to mounting plate
dimensions on the next page to help you determine the
optimal position. The wall hole should have a 65mm
diameter at least, and at a slightly lower angle to
facilitate drainage.
2. Using a 65mm or 90mm (depending on models) core drill,
drill a hole in the wall. Make sure that the hole is drilled at a
slight downward angle, so that the outdoor end of the hole
is lower than the indoor end by about 5mm to 7mm. This
will ensure proper water drainage.
3. Place the protective wall cuff in the hole. This protects the
edges of the hole and will help seal it when you finish the
installation process.
CAUTION
When drilling the wall hole, make sure to avoid wires,
plumbing, and other sensitive components.

Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating sleeve attached
to the back of the unit. You must prepare the piping before
passing it through the hole in the wall.
1. Based on the position of the wall hole relative to the
mounting plate, choose the side from which the piping will
exit the unit.
2. If the wall hole is behind the unit, keep the knock-out panel
in place. If the wall hole is to the side of the indoor unit,
remove the plastic knock-out panel from that side of the
unit. This will create a slot through which your piping can
exit the unit. Use needle nose pliers if the plastic panel is
too difficult to remove by hand.
3. Connect drain hose step. If there is no embedded
piping, connect the indoor unit’s refrigerant piping to the
connective piping that will join the indoor and outdoor units.
Refer to the Refrigerant piping connection section of this
manual for detailed instructions.
NOTE ON PIPING ANGLE: Refrigerant piping can exit the
indoor unit from four different angles: left-hand side, right-
hand side, left rear, right rear.
CAUTION
Be extremely careful not to dent or damage the piping
while bending them away from the unit. Any dents in the
piping will affect the unit’s performance.
Step 5: Connect drain hose
By default, the drain hose is attached to the left-hand side
of unit (when you’re facing the back of the unit). However, it
can also be attached to the right-hand side. To ensure proper
drainage, attach the drain hose on the same side that your
refrigerant piping exits the unit. Attach drain hose extension
(purchased separately) to the end of drain hose.
• Wrap the connection point firmly with teflon tape to ensure
a good seal and to prevent leaks.
• For the portion of the drain hose that will remain indoors,
wrap it with foam pipe insulation to prevent condensation.
• Remove the air filter and pour a small amount of water into
the drain pan to make sure that water flows from the
unit smoothly.
NOTE ON DRAIN HOSE

Step 6: Wrap piping and cables
Before passing the piping, drain hose, and the signal cable
through the wall hole, you must bundle them together to save
space, protect them, and insulate them.
1. Bundle the drain hose, refrigerant pipes, and signal cable.
Drain hose must be on bottom
Make sure that the drain hose is at the bottom of the
bundle. Putting the drain hose at the top of the bundle can
cause the drain pan to overflow, which can lead to fire or
water damage.
Do not intertwine signal cable with
other wires
While bundling these items together, do not intertwine or
cross the signal cable with any other wiring.
2. Using adhesive vinyl tape, attach the drain hose to the
underside of the refrigerant pipes.
3. Using insulation tape, wrap the signal wire, refrigerant
pipes, and drain hose tightly together.

When wrapping the bundle, keep the ends of the piping
unwrapped. You need to access them to test for leaks
during of the installation process (refer to Electrical checks
and Leak checks section of this manual).
Step 7: Mount indoor unit
If you installed new connective piping to the outdoor unit,
do the following:
1. If you have already passed the refrigerant piping through
the hole in the wall, proceed to Step 4.
2. Otherwise, double-check that the ends of the refrigerant
pipes are sealed to prevent dirt or foreign materials from
entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant pipes, drain
hose, and signal wire through the hole in the wall.
4. Hook the top of the indoor unit on the upper hook of the
mounting plate.
5. Check that unit is hooked firmly on mounting by applying
slight pressure to the left and right-hand sides of the unit.
