CAUTION
The unit body should align perfectly with the hole.
Ensure that the unit and the hole are the same size
before moving on.
1. Drill 4 holes 50mm deep at the ceiling hook positions in the
internal ceiling. Be sure to hold the drill at a 90° angle
to the ceiling.
2. Using a hammer, insert the ceiling hooks into the pre-drilled
holes. Secure the bolt using the included washers and nuts.
3. Install the four suspension bolts.
4. Mount the indoor unit. You will need two people to lift and
secure it. Insert suspension bolts into the unit’s hanging
holes. Fasten them using the included washers and nuts.
NOTE: The bottom of the unit should be 10-18mm higher
than the ceiling board. Generally, L (indicated in the
following figure) should be half the length of the suspension
bolt or long enough to prevent the nuts from coming off.
NOTE: Ensure that the indoor unit is completely level.
The unit is equipped with a built-in drain pump and
float switch. If the unit is tilted against the direction of
condensate flows (the drainpipe side is raised), the float
switch may malfunction and cause water to leak. Improper

Note for new home installation
When installing the unit in a new home, the ceiling hooks
can be embedded in advance. Make sure that the hooks
do not come loose due to concrete shrinkage. After
installing the indoor unit, fasten the installation paper
template onto the unit with bolts to determine in advance
the dimension and position of the opening on the ceiling.
Follow the instructions above for the remainder of the
installation.
Step 3: Drill wall hole for connective piping
1. Determine the location of the wall hole based on the
location of the outdoor unit.
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 12mm. 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 piping or cables.
Step 4: Connect drain hose
The drainpipe is used to drain water away from the unit. Improper installation may cause unit and property damage.
CAUTION
• Insulate all piping to prevent condensation, which
could lead to water damage.
• If the drainpipe is bent or installed incorrectly, water
may leak and cause a water-level switch malfunction.
• In HEAT mode, the outdoor unit will discharge water.
Ensure that the drain hose is placed in an appropriate
area to avoid water damage and slippage.
•Do not pull the drainpipe forcefully. This could
disconnect it.

Indoor drainpipe installation
Install the drainpipe as illustrated in the following figure.
Note on drainpipe installation
• When using an extended drainpipe, tighten the indoor
connection with an additional protection tube to
prevent it from pulling loose.
• The drainpipe should slope downward at a gradient of
at least 1/100 to prevent water from flowing back into
the air conditioner.
•To prevent the pipe from sagging, space hanging wires
every 1000mm – 1500mm.
• If the outlet of the drainpipe is higher than the body’s
pump joint, provide a lift pipe for the exhaust outlet of
the indoor unit. The lift pipe must be installed no higher
than 750mm from the ceiling board and the distance
between the unit and the lift pipe must be less than
300mm. Incorrect installation could cause water to flow
back into the unit and flood.
•To prevent air bubbles, keep the drain hose level or
slightly sloping up before the riser.
NOTE: When connecting multiple drainpipes, install the pipes
as illustrated in the following figure.

Pass the drain hose through the wall hole. Make sure the water
drains to a safe location where it will not cause water damage or
a slipping hazard.
NOTE: The drainpipe outlet should be at least 5cm above the
ground. If it touches the ground, the unit may become blocked
and malfunction. If you discharge the water directly into a sewer,
make sure that the drain has a U or S pipe to catch odours that
might otherwise come back into the house.

6. Refrigerant piping connection
When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter the unit. The presence
of other gases or substances will lower the unit’s capacity, and can cause abnormally high pressure in the refrigeration cycle.
This can cause explosion and injury.
Note on pipe length
Ensure that the length of the refrigerant pipe, the number of bends, and the drop height between the indoor and outdoor units
meets the requirements shown in the following table :
The maximum length and drop height based on models. (Unit: metres.)
Type of model Models Length of piping Maximum drop height
KCI KCI42 7530
CAUTION
• Oil traps
If the indoor unit is installed higher than the outdoor unit:
If oil flows back into the outdoor unit’s compressor, this
might cause liquid compression or deterioration of oil
return. Oil traps in the rising gas piping can prevent this.
An oil trap should be installed every 10m of vertical
suction line riser.
CAUTION
If the outdoor unit is installed higher than the indoor unit:
It is recommended that vertical suction risers not be
up-sized. Proper oil return to the compressor should be
maintained with suction gas velocity. If velocities drop
below 7.62m/s, oil return will be decreased. An oil trap
should be installed every 6m of vertical suction line riser.

CAUTION
• The branching pipe must be installed horizontally.
An angle of more than 10° may cause malfunction.
•Do not install the connecting pipe until both indoor
and outdoor units have been installed.
• Insulate both the gas and liquid piping to prevent
water leakage.
Step 1: Cut pipes
When preparing refrigerant pipes, take extra care to cut and
flare them properly. This will ensure efficient operation and
minimise the need for future maintenance.
1. Measure the distance between the indoor and outdoor units.
2. Using a pipe cutter, cut the pipe a little longer than the
measured distance.
3. Make sure that the pipe is cut at a perfect 90° angle.
DO NOT DEFORM PIPE
WHILE CUTTING
Be extra careful not to damage, dent, or deform the
pipe while cutting. This will drastically reduce the heating
efficiency of the unit.
Step 2: Remove burrs
Burrs can affect the air-tight seal of refrigerant piping
connection. They must be completely removed.
1. Hold the pipe at a downward angle to prevent burrs from
falling into the pipe.
2. Using a reamer or deburring tool, remove all burrs from the
cut section of the pipe.
Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight seal.
1. After removing burrs from cut pipe, seal the ends with PVC
tape to prevent foreign materials from entering the pipe.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of pipe. Make sure they are
facing in the right direction, because you can’t put them on
or change their direction after flaring.
4. Remove PVC tape from ends of pipe when ready to
perform flaring work.
5. Clamp flare form on the end of the pipe. The end of the
pipe must extend beyond the flare form.
6. Place flaring tool onto the form.
7. Turn the handle of the flaring tool clockwise until the pipe is
fully flared. Flare the pipe in accordance with the dimensions.

8. Remove the flaring tool and flare form, then inspect the end
of the pipe for cracks and even flaring.
Step 4: Connect pipes
Connect the copper pipes to the indoor unit first, then connect
it to the outdoor unit. You should first connect the low-pressure
pipe, then the high-pressure pipe.
1. When connecting the flare nuts, apply a thin coat of
refrigeration oil to the flared ends of the pipes.
2. Align the centre of the two pipes that you will connect.
3. Tighten the flare nut as tightly as possible by hand.
4. Using a spanner, grip the nut on the unit tubing.
5. While firmly gripping the nut, use a torque wrench to tighten
the flare nut according to the torque values in above table.
NOTE: Use both a spanner and a torque wrench when
connecting or disconnecting pipes to/from the unit.
CAUTION
• Ensure you wrap insulation around the piping. Direct
contact with the bare piping may result in burns or
frostbite.
• Make sure the pipe is properly connected. Over-
tightening may damage the bell mouth and under-
tightening may lead to leakage.
