Meanings of DANGER, WARNING, CAUTION, and NOTE
symbols:
DANGER .............. Indicates an imminently hazardous
situation which,if not avoided, will
result in death or serious injury.
WARNING ............ Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.

DANGER
• Refrigerant gas is heavier than air and displaces oxygen. A massive leak could lead to oxygen depletion,
especially in basements, and an asphyxiation hazard
could occur leading to serious injury or death.

• To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end or cover it with tape.
• Do not allow anything other than the designated refrigerant
to get mixed into the refrigerant circuit, such as air, etc. If
any refrigerant gas leaks while working on the unit, ventilate the room immediately.
6-2
Connecting the refrigerant piping
• Apply ester oil or ether oil around the flare portions before
connecting.
• The flare nuts used must be those included with the main
body.
• Over-tightening may damage the flare and cause a refrigerant leakage.
Not recommendable but in case of emergency
You must use a torque wrench but if you are obliged to install
the unit without a torque wrench, you may follow the installation method mentioned below.
After the work is finished, make sure to check that there
is no gas leak.
When you keep on tightening the flare nut with a spanner,
there is a point where the tightening torque suddenly
increases. From that position, further tighten the flare nut the
angle shown below:
Table 4
• When connecting the flare nut, coat the flare both inside
and outside with ester oil or ether oil and initially tighten by
hand 3 or 4 turns before tightening firmly.

Piping Insulation
• Execute heat insulation work completely on both sides of
the gas piping and the liquid piping or a water leakage can
result .
• When using a heat pump, the temperature of the gas piping
can reach approximately 250°F, so use sufficiently resistant insulation.
• Where the temperature and humidity of the refrigerant piping sections might exceed 86°F or RH80%, reinforce the
refrigerant insulation (13/16” or thicker) or condensation
may form on the surface of the insulating material.
• Check the pipe connector for gas leaks, then insulate it as
shown in the drawing below.
• Make absolutely sure to install heat insulation on the pipeconnecting section after checking gas leakage. Thoroughly
studythe following figure and use the attached heat insulating materials for fitting. Fasten both ends with the accessory clamps.

DRAIN PIPING WORK
Install the drain pipe as shown below and take measures
against condensation. Improperly installed piping could
lead to leaks on furniture and belongings.
(1) Install the drain piping.
• The diameter of the drain pipe should be greater than or
equal to the diameter of the connecting pipe (vinyl tube
pipe size: 1 3/16”; outer dimension: 1 1/4”).
• Keep the drain pipe short and sloping downward at a gradient of at least 1/100 to prevent air pockets from forming.
• If the drain hose cannot be sufficiently set on a slope, execute the drain-raising pipe.
• To keep the drain hose from sagging, use support spacing
every 3.28 to 4.92 ft.
Fig. 1
CAUTION
• Be sure to insulate any field piping all the way to the piping
connection inside the unit. Any exposed piping may cause
condensation or burns if touched.
6-4
Brazing Refrigerant Piping
• Before brazing local refrigerant piping, blow nitrogen gas
through the piping to expel air. If this is not done, a large
amount of oxide film develops inside the piping and could
cause system malfunction.
• Only begin brazing after having carried out nitrogen substitution or while inserting nitrogen into the refrigerant piping.
Once this is done, connect the indoor unit with a flared or a
flanged connection.
• Nitrogen should be set to 2.9 psi with a pressure-reducing
valve if brazing while inserting nitrogen into the piping.

must conform to local codes.
• Use copper wire only.
• Follow the WIRING DIAGRAM attached to the unit body to
wire the outdoor unit, indoor units, and the remote controller. For details on connecting the remote controller, refer to
the INSTALLATION MANUAL OF REMOTE CONTROLLER.
• All wiring must be performed by an authorized electrician.
• This system consists of multiple indoor units. Mark each
indoor unit as unit A, unit B, and so forth. Ensure the terminal board wiring to the outdoor unit and BS unit are properly matched. If controls wiring and piping between the
outdoor and indoor units are mismatched, a communications malfunction is likely.
• A circuit breaker capable of shutting down the power supply
to the entire system must be installed.

CAUTION
NOTE
1. Use round crimp-style terminals for connecting wires to
the power supply terminal block.
If unavailable, observe the following points when wiring.
• Do not connect wires of different gauge to the same
power supply terminal as looseness in the connection
may cause overheating.
• Use the specified electric wire. Connect the wire
securely to the terminal. Lock the wire down without
applying excessive force to the terminal. Tightening

• To avoid short circuits in the electric parts box, be sure to
apply the sealing material or putty (not included) to the wiring hole to prevent the infiltration of water, insects or other
small creatures.
• When clamping the wires, be sure no pressure is applied to
the wire connections by using the included clamping material to make appropriate clamps. Also, when wiring, make
sure the lid on the electric parts box fits snugly by arranging
the wires neatly and attaching the electric parts box lid
firmly. When attaching the electric parts box lid, make sure
no wires get caught in the edges. Pass wiring through the
wiring through holes to prevent damage to them.
• Make sure the remote controller wiring, the wiring between
the units, and other electrical wiring do not pass through
the same locations outside of the unit, separating them by
at least 1 15/16”, otherwise electrical noise (external static)
could cause mistaken operation or breakage.
5. For remote controller wiring, refer to the INSTALLATION
MANUAL OF REMOTE CONTROLLER attached to the
remote controller.
6. Use only specified wire and connect wires to terminals
tightly. to terminals. Be careful wires do not place external
stress on terminals. Keep wiring in neat order so as not to
