N Use appropriate tools and piping materials for installation.
The pressure of R410A is 1.6 times higher than R22. Not using the appropriate
tools and materials, or improper installation could cause the pipes to burst causing
an injury.
N When pumping down the refrigerant, stop the compressor before disconnecting
the refrigerant pipes.
If the refrigerant pipes are disconnected while the compressor is running and the
stop valve is open, air could be drawn in and the pressure in the refrigeration cycle
could become abnormally high, causing the pipes to burst.
N When installing the unit, securely connect the refrigerant pipes before starting
the compressor.
If the compressor is started before the refrigerant pipes are connected and the
stop valve is open, air could be drawn in and the pressure in the refrigeration cycle
could become abnormally high, causing the pipes to burst.

NDepending on the installation area, install a Ground Fault Interrupt (GFI) circuit
breaker.
If the Ground Fault Interrupt (GFI) circuit breaker is not installed, an electric shock

2-3. CONNECTING WIRES FOR INDOOR UNIT
Note:
When the indoor unit is powered from the outdoor unit, depending on local code, a discon-
nect switch needs to be installed to a power supply circuit.
1) Remove the panel assembly. (Refer to 5-1.)
2) Place the upper part of the indoor unit on the installation plate.
3) Remove corner box and conduit cover.
4) Attach conduit pipe (for rear piping) / elbow joint (for right, left, or downward piping) to
conduit cover with lock nut. The thread of the installed conduit pipe / elbow joint appear-
ing inside should be less than 3/8 in. (10 mm). (Fig. 1) Elbow joint should appear less
than 1-3/16 in. (30 mm) outside. (Fig. 2)
5) Process the end of ground wire (Fig. 3). Connect it to the ground terminal of electrical
parts box.
6) Process the end of indoor/outdoor unit connecting wire (A) (Fig. 3). Attach it to the
terminal block. Be careful not to make mis-wiring. Attach the wire to the terminal block
securely so that its core cannot be seen, and no external force affects the connecting
section of the terminal block.
7) Firmly tighten the terminal screws. After tightening, verify that the wires are tightly fas-
tened.
8) Secure indoor/outdoor unit connecting wire (A) and the ground wire with conduit cover.
Never fail to hook the claw of the conduit cover to the electrical box. Attach the conduit
cover securely. (Fig. 4)
9) According to the piping direction, remove the shaded part of the left side of box (Fig. 5)
or corner box (Fig.6). Reinstall corner box and front panel.

2-4-1. PIPE FORMING
• Place the drain hose below the refrigerant piping.
• Make sure that the drain hose is not crowded or bent.
• Do not pull the hose when applying the tape.
• When the drain hose passes the room, be sure to wrap it with insulation material
¿HOGVXSSOLHG
Note:
Make sure not to damage the cover of refrigerant pipe when attaching it back on with
screws.
Left or left-rear piping
Note:
Be sure to reattach the drain hose and the drain cap if the piping is being installed on
left or bottom left of unit, otherwise, water could drip down from the drain hose.

Felt tape (7) overlap width should be 1/3 the tape width. Use a bandage stopper at
the end of felt tape (7).
2) Pull out the drain cap at the back right of the indoor unit. (Fig. 1)
• Hold the convex section at the end and pull the drain cap.
3) Pull out the drain hose at the back left of the indoor unit. (Fig. 2)
• Hold the claw marked by the arrows and pull out the drain hose forward.
4) Put the drain cap into the section to which the drain hose is to be attached at the rear
of the indoor unit. (Fig. 3)
• Insert a screwdriver into the hole on the cap and insert the cap fully into the drain
pan.
5) Insert the drain hose fully into the drain pan at the back right of the indoor unit. (Fig. 4)
• Check if the hose is hooked securely to the projection of its inserting part at the
drain pan.
6) Insert the drain hose into wall hole sleeve (C), and attach the upper part of indoor
unit onto the installation plate (1). Then, shift the indoor unit completely to the left to
make placing the piping in the back of the unit easier.
7) Cut out a piece of cardboard from the shipping box, roll it up, hook it onto the back
rib, and use it as a spacer to lift the indoor unit. (Fig. 5)
8) Connect the refrigerant piping with the extension pipe (B).
9) Attach the lower part of the indoor unit into the installation plate (1).
Remove panel for piping

6) Quickly remove gauge manifold valve from service port of stop valve.
7) After refrigerant pipes are connected and evacuated, fully open all stop valves on both
sides of gas pipe and liquid pipe. Operating the unit without fully opening the valves
lowers the performance and causes problems.
8) Refer to 1-3. SPECIFICATIONS, and charge the prescribed amount of refrigerant if
needed. Be sure to charge slowly with liquid refrigerant. Otherwise, composition of the
refrigerant in the system may be changed and affect performance of the air conditioner.
9) Tighten cap of service port.
10) Conduct a leak test

Pressure gauge
(for R410A)
4-2. TEST RUN
1) Insert power supply plug into the power outlet and/or turn
on the breaker.
2) Press the E.O. SW once. Test run will be performed for
30 minutes. If the power lamp blinks every 0.5 seconds,
inspect the indoor/outdoor unit connecting wire (A). After
the test run, emergency COOL mode (75ºF [24ºC] COOL)
will start.
3) To stop operation, press the E.O. SW several times until
all LED lamps turn off. Refer to operating instructions for
details.
Checking the remote (infrared) signal reception
Press the ON/OFF button on the remote controller and listen for an audible indicator from
the indoor unit. Press the ON/OFF button again to turn the air conditioner off.
• Once the compressor stops, the restart preventive device operates so the compressor
will not operate for 3 minutes to protect the air conditioner.
4-3. AUTO RESTART FUNCTION
This product is equipped with an auto restart function. When the power supply is cut off
during operation, such as during blackouts, the function automatically starts operation in
the previous setting once the power supply is resumed. (Refer to the operating instructions
for details.)
Emergency
operation switch
(E.O. SW)
Caution:
• After test run or remote signal reception check, turn off the unit with the E.O. SW or
the remote controller before turning off the power supply. If this procedure is not per-
formed, the unit will automatically begin operation when power supply is resumed.
To the user
• After installing the unit, explain to the user about auto restart function.
• If auto restart function is unnecessary, it can be deactivated. Consult the service rep-
resentative to deactivate the function. Refer to the service manual for details.

4-4. REMOTE CONTROLLER SETTING
Set the slide switch of the remote controller according to where the indoor unit is installed
in the area. If the switch is not set correctly, the air conditioner may not function properly.
Location of unit in area:
Left: Distance to objects (wall, cabinet, etc.) is less
than 19-11/16 in. (50 cm) to the left
Center: Distance to objects (wall, cabinet, etc.) is
more than 19-11/16 in. (50 cm) to the left and right
Right: Distance to objects (wall, cabinet, etc.) is less
than 19-11/16 in. (50 cm) to the right
1) Remove the front lid.
2) Set the slide switch according to the installed position of the indoor unit.
3) Insert two (AAA) batteries.
4) Reattach the front lid.
5) Press the RESET button gently using a thin instrument.
5-3. PUMPING DOWN
When relocating or disposing of the air conditioner, pump down the system following
the procedure below so that refrigerant is not released into the atmosphere.
1) Connect the gauge manifold valve to the service port of the stop valve on the gas
pipe side of the outdoor unit.
2) Fully close the stop valve on the liquid pipe side of the outdoor unit.
3) Close the stop valve on the gas pipe side of the outdoor unit almost completely
so that it can be easily closed fully when the pressure gauge shows 0 MPa [Gauge]
(0 lbf/in.2[0 kgf/cm2]).
4) Start the emergency COOL operation.
To start the emergency operation in COOL mode, disconnect the power supply
plug and/or turn off the breaker. After 15 seconds, connect the power supply plug
and/or turn on the breaker, and then press the E.O. SW once. (The emergency
COOL operation can be performed continuously for up to 30 minutes.)
5)
Fully close the stop valve on the gas pipe side of the outdoor unit when the pressure
gauge shows 0.05 to 0 MPa [Gauge] (approx. 7.25 to 0 lbf/in2[0.5 to 0 kgf/cm2]).
6) Stop the emergency COOL operation.
Press the E.O. SW twice to stop the operation.
