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.
This symbol refers to a hazard or
unsafe practice which can result
in severe personal injury or death.
This symbol refers to a hazard or
CAUTION
unsafe practice which can result
in personal injury or product or
property damage.
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.
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED ELECTRICIAN
SHOULD ATTEMPT TO WIRE THIS SYSTEM.
●
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 accidentaly 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.
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.
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 Sys-tems)
Install the outdoor unit on a raised platform that is higher than
drifting snow. Provide snow vents.
Ventilate the room well, in the event that refrigerant gas
leaks during the installation. Be careful not to allow contact
of the refrigerant gas with a flame as this will cause the
generation of poisonous gas.
●
Keep all tubing runs as short as possible.
●
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.
NOTE
Depending on the system type, liquid and gas lines may be
either narrow or wide. Therefore, to avoid confusion the
refrigerant tubing for your particular model is specified as either
“narrow” or “wide” rather than as “liquid” or “gas”.
Turn 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 when installation is finished. Check that no
metal scraps or bits of wiring have been left inside the unit.
CAUTION
●
Ventilate any enclosed areas when installing or testing the
refrigeration system. Contact of refrigerant gas with fire or
heat can produce poisonous gas.
●
Confirm after installation that no refrigerant gas is leaking. If
the gas comes in contact with a burning stove, gas water
heater, electric room heater or other heat source, it can
cause the generation of poisonous gas.

REMARKS:1. Value obtained in the actual place where the unit is installed may be slightly higher than the values shown
in this graph because of the conditions of operation, the structure of the building, the background noise and
other factors.
2. The test results were obtained from an nechoic room.
NOTE
To evaluate “Noise level” the maximum number of the measured OCTAVE BAND SOUND PRESSURE LEVEL is used.
Read the number on each BAND CENTER FREQUENCIES (horizontal axis) ranging from 63 Hz to 8000 Hz and select the
maximum value (vertical axis) among them.

If external static pressure is too great (due to long extension
of ducts, for example), the air flow volume may drop too low
at each air outlet. This problem may be solved by increasing
the fan speed using the following procedure:
(1) Remove 4 screws on the electrical component box and
remove the cover plate.
(2) Disconnect the fan motor sockets in the box.
(3) Take out the jumper cable (sockets at both ends) clamped
in the box.
(4) Securely connect the jumper cable sockets
between the disconnected fan motor sockets in step 2.
(5) Place the cable neatly in the box and reinstall the cover
plate.

How to read the diagram
The vertical axis is the external static pressure (Pa) while the horizontal axis represents the AIR FLOW (CFM).
The characteristic curves for “HT”, “H”, “M” and “L” fan speed control are shown.
The nameplate values are shown based on the “H” air flow. For the 26 type, the air flow is 636 CFM, while the
external static pressure is 49 Pa at “H” position. If external static pressure is too great (due to long extension of
5
duct, for example), the air flow volume may drop too low at each air outlet.
This problem may be solved by increasing the fan speed as explained above.

1-11 Installation Instructions
Tubing Length
Single type
Refrigerant tubing between the indoor and outdoor
units should be kept as short as possible.
The length of the refrigerant tubes between the
indoor and outdoor units are limited by the elevation
difference between the 2 units. During tubing work,
try to make both the tubing length (L) and the
difference in elevation (H1) as short as possible.
Refer to Table 1-2.

CAUTION
Concerning inlet-side distance “C” (Fig. 1-2)
The minimum for distance “C” is 6" if there are no obstructions on the outlet side
(wall *1 side) and *2 or *4 is not present. In all other cases, the minimum for distance
“C” is 8".
If the unit is installed with the outlet side facing wall *1, then there must be no obstructions on 2 of the remaining 3 sides: *2, *3, *4.
If wall *1 is on the outlet side (Fig. 1-2), or if obstructions are present on all 3 sides *2,
*3, and *4 (Fig. 1-2), then the minimum distance for “A” and “B” is 80" (Fig. 1-3). Even if
there is no wall on the outlet side, a minimum of 3.3 ft. is required.

it is difficult to keep a space of min. 20" between the
air discharge outlet and an obstacle.
the air discharge outlet is facing a sidewalk and
discharged hot air may bother passers-by.
Refer to Fig. 1-5.
Installing the Unit in Heavy Snow Areas
In locations with strong wind, snow-proof ducting should
be fitted and direct exposure to the wind should be
avoided as much as possible.
Countermeasures against snow and wind
In regions with snow and strong wind, the following
problems may occur when the outdoor unit is not
provided with a platform and snow-proof ducting:
a) The outdoor fan may not run and damage to the unit
may occur.
b) There may be no air flow.
c) The tubing may freeze and burst.
d) The condenser pressure may drop because of strong
wind, and the indoor unit may freeze.
Precautions for Installation in Heavy Snow Areas
Air discharge
Air discharge
Fig. 1-5
In regions with significant snowfall, the outdoor unit
should be provided with a platform and snow-proof duct.

1) The platform should be higher than the max. snow
depth. (Fig. 1-6)
2) The 2 anchoring feet of the outdoor unit should be
used for the platform, and the platform should be
installed beneath the air intake side of outdoor unit.
3) The platform foundation must be firm and the unit
must be secured with anchor bolts.
4) In case of installation on a roof subject to strong
wind, countermeasures must be taken to prevent the
unit from being blown over.
