WARNING
Important!
Please Read Before Starting
This air conditioning system meets strict safety and
operating standards. As the installer or service person, it
is an important part of your job to install or service the
system so it operates safely and efficiently.
For safe installation and trouble-free operation, you
must:
Carefully read this instruction booklet before beginning.
Follow each installation or repair step exactly as shown.
Observe all local, state, and national electrical codes.
Pay close attention to all warning and caution notices
given in this manual.
If Necessary, Get Help
These instructions are all you need for most installation
sites and maintenance conditions. If you require help for
a special problem, contact our sales/service outlet or
your certified dealer for additional instructions.
In Case of Improper Installation
The manufacturer shall in no way be responsible for
improper installation or maintenance service, including
failure to follow the instructions in this document.
Do not supply power to the unit until all wiring and
tubing are completed or reconnected and checked.
Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and
inadequate grounding can cause accidental injury or
death.
Ground the unit following local electrical codes.
Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.
When Transporting
Be careful when picking up and moving the indoor and
outdoor units. Get a partner to help, and bend your knees
when lifting to reduce strain on your back. Sharp edges or
thin aluminum fins on the air conditioner can cut your
fingers.
When Installing
In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the
unit’s weight. It may be necessary to construct a strong
wood or metal frame to provide added support.
In a Room
Properly insulate any tubing run inside a room to prevent
"sweating" that can cause dripping and water damage to
walls and floors.
In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a
solid, level foundation for the outdoor unit. This prevents
water damage and abnormal vibration.
In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a
metal frame. Provide a suitable air baffle.
In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher
than drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
Use the flare method for connecting tubing.
Apply refrigerant lubricant to the matching surfaces of
the flare and union tubes before connecting them, then
tighten the nut with a torque wrench for a leak-free
connection.
Check carefully for leaks before starting the test run.
When Servicing
Tu rn the power off at the main power box (mains) before
opening the unit to check or repair electrical parts and
wiring.
Keep your fingers and clothing away from any moving
parts.
Clean up the site after you finish, remembering to check
that no metal scraps or bits of wiring have been left
inside the unit being serviced.
Others
Ventilate any enclosed areas when installing or testing
the refrigeration system. Escaped refrigerant gas, on
contact with fire or heat, can produce dangerously toxic
gas.
Confirm upon completing installation that no refrigerant
gas is leaking. If escaped gas comes in contact with a
stove, gas water heater, electric room heater or other
heat source, it can produce dangerously toxic gas.

Insulation of Refrigerant Tubing
Because capillary tubing is used in the outdoor unit, both the
wide and narrow tubes of this air conditioner become cold. To
prevent heat loss and wet floors due to dripping of
condensation, both tubes must be well insulated with a
proper insulation material. The thickness of the insulation
should be a min. 8 mm.
After a tube has been insulated,
never try to bend it into a narrow
curve because it can cause the tube
to break or crack.

WARNING
7. INSTALLATION INSTRUCTIONS
7-1. Installation Site Selection
7-1-1. Indoor Unit
To prevent abnormal heat
generation and the possibility
of fire, do not place obstacles,
enclosures and grilles in front
of or surrounding the air
conditioner in a way that may
block air flow.
For stable operation of
the air conditioner, do not
install wall-mounted type
indoor units less than
1.5 m from floor level.
AVOID:
direct sunlight.
nearby heat sources that may affect performance of
the unit.
areas where leakage of flammable gas may be
expected.
places where large amounts of oil mist exist.
DO:
select an appropriate position from which every corner
of the room can be uniformly cooled. (High on a wall
is best.)
select a location that will hold the weight of the unit.
select a location where tubing and drain hose have
the shortest run to the outside.
allow room for operation and maintenance as well as
unrestricted air flow around the unit. (Fig. 1)
install the unit within the maximum elevation
difference (H) above or below the outdoor unit and
within a total tubing length (L) from the outdoor unit as
detailed in Table 1 and Fig. 2.
Install the indoor unit more than 1 meter away from
any antenna or power lines or connecting wires used
for television, radio, telephone, security system, or
intercom. Electrical noise from any of these sources
may affect operation.
Table 1
Model
KRV96 / 126
* If total tubing length becomes 7.5 to 15 m, charge additional refrigerant (R410A) by 15 g/m.
No additional charge of compressor oil is necessary.

damp, humid or uneven locations.
DO:
position the outdoor unit in a protected location
where snow will not blow into it.
choose a place as cool as possible.
choose a place that is well ventilated.
allow enough room around the unit for air intake/
exhaust and possible maintenance. (Fig. 5a)
provide a solid base (level concrete pad, concrete
block, 10 40 cm beams or equal), a minimum of
10 cm above ground level to reduce humidity and
protect the unit against possible water damage and
decreased service life. (Fig. 5a)
Install cushion rubber under unit's feet to reduce
vibration and noise. (Fig. 5b)
use lug bolts or equal to bolt down unit, reducing
vibration and noise.
Install in a location where no antenna of a
television or radio exists within 3 meters.
