Notes:
1. Nominal cooling capacities are based on the following conditions:
Return air temperature: 80°FDB, 67°FWB
Outdoor temperature: 95°FDB
Equivalent ref. piping length: 25 ft / 7.5 m (Horizontal)
2. Nominal heating capacities are based on the following conditions:
Return air temperature: 70°FDB.
Outdoor temperature: 47°FDB, 43°FWB
Equivalent ref. piping length: 25 ft / 7.5 m (Horizontal)
3. Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.
4. Anechoic chamber conversion value, measured under JISB8616 conditions. During actual operation,
these values are normally somewhat higher as a result of installation conditions.

REFRIGERANT PIPING WORK
For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit.
Execute heat insulation work completely on both sides of
the gas piping and the liquid piping. Otherwise, a water
leakage can result.
When using a heat pump, the temperature of the gas piping
can reach up to approximately 250°F, so use sufficiently resistant insulation.
In cases where the temperature and humidity of the
refrigerant piping sections might exceed 86°F or RH80%,
reinforce the refrigerant insulation by 13/16” or thicker.
Condensate may form on the surface of the insulating
material.
Before refrigerant piping work, check which type of refrigerant is used. Proper operation is not possible if the types
of refrigerant are not the same.
NOTE
NOTE
• Use the installation mount for installation. Check whether
the wall is strong enough to bear the weight of the unit or
not. If there is a risk, reinforce the wall before installing the
unit.
• The unit requires a minimum 2.5 inch clearance on the
underside for air intake. Ensure the unit is level when
installed so that drainage flows smoothly. If tilted or on an
incline, water can leak.
• Operating sound may be louder if installed on a more solid
wall.
FXLQ-M / FXNQ-M
• Use a pipe cutter and flare suitable for the type of refrigerant.
• 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,
immediately ventilate the room.
When connecting refrigerant piping:
• Ensure that theoutdoor unit is charged with refrigerant.
• Use copper alloy seamless pipes.
• To prevent flare nut cracking and gas leaks, be sure to use
both a spanner and torque wrench together, as shown in
the drawing, when connecting or disconnecting pipes to /
from the unit.
• Refer to Table 2 for the dimensions of flare.
20
Installation
EDUS39-600-F7
• When connecting the flare nut, coat the flare section (both
inside and outside) with ester oil or ether oil, rotate three or
four times first, then screw in.
• Refer to the Table 2 for tightening torque.
• After inspecting pipe joints for gas leakage, be sure to insulate with the accessory joint insulation for fitting (3) (4) while
referring to the figure below. Fasten both ends with clamps
(6).
Wrap only the gas line side with the sealing pad (5). Bend
the pad over the insulation for fitting (union) from above.
Ester oil or ether oil.
DANGER
• Use of oxygen may cause an explosion resulting in serious
injury or death. Only use nitrogen gas.
• Refrigerant gas may produce toxic gas if it comes in contact
with fire such as from a fan heater, stove or cooking device.
Exposure to this gas could cause severe injury or death.
• Before brazing local refrigerant piping, nitrogen gas shall
be blown through the piping to expel air from the piping.
If brazing is done without nitrogen gas blowing, a large
amount of oxide film develops inside the piping, and could
cause system malfunction.
• When brazing the refrigerant piping, 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.

• CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING
Do not use flux when brazing refrigerant piping. Therefore,
use the phosphor copper brazing filter metal (BCuP) which
does not require flux.
Flux has an extremely negative effect on refrigerant piping
systems. For instance, if chlorine based flux is used, it will
cause pipe corrosion. If the flux contains fluorine, it will
damage the refrigerant oil.

Installation
Make sure the remote controller wiring, the wiring between the
units, and other electric wiring do not pass through the same
locations outside of the unit, separating them by at least 5”, to
prevent the possibility of electric noise (external static) causing faulty operation or breakage.. PRECAUTIONS
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 gauges to the same
power supply terminal. 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
torque: 0.97ft.lbf ±10 %)

2. Tightening torque for the terminal screws.
• Use the correct screwdriver for tightening the terminal
screws. If the blade of screwdriver is too small, the head
of the screw might be damaged, and the screw will not
be properly tightened.
• If the terminal screws are tightened too hard, they might
be damaged.
• Refer to the table below for the tightening torque of the
terminal screws.

3. Do not connect wires of different gauge to the same
grounding terminal. Looseness in the connection may
deteriorate protection.
4. Outside of the unit, keep transmission wiring at least 5”
away from power supply wiring. The equipment may malfunction if subjected to electric (external) noise.
5. For remote controller wiring, refer to the INSTALLATION
MANUAL OF REMOTE CONTROLLER.
