4. PREPARATIONS BEFORE INSTALLA-
TION
(1) Relative positions of indoor unit and suspension bolt.
(Refer to Fig. 2)
(2) Install a canvass duct to the air discharge outlet and air inlet
so that vibration from the machine body isn’t transmitted to
the duct or ceiling.
You should also apply acoustic (insulation material) to the
inside of the duct, and vibration insulation rubber to the sus-
pension bolts.
(3) Install suspension bolts.
(Use bolts of 10 mm diameter.)
•Install the equipment where supporting structures are
strong enough to bear the equipment’s weight. Use
embedded inserts or anchor bolts with new buildings and
hole-in-anchors with old buildings.
5. INDOOR UNIT INSTALLATION
Installing optional accessories before installing the indoor
unit is easier.
As for the parts to be used for installation work, be sure to use
the provided accessories and specified parts designated by our
company.
(1) Fix the hanger bracket to the suspension bolt. Tighten both
upper and lower nuts firmly using washers.
(2) Adjust the height of the unit.
(3) Make sure the unit is
level.
•Level the unit with a
level when install-
ing. If the unit is not
level, it could
become the source
of water leaks.
•When leveling the
unit, check all four
corners with a level
or a vinyl tube con-
taining water. (See
the figure on the
right.)
(4) Tighten the nuts on the top.
(5) Insulate the two hanger brackets on the discharge side with
the sealing pad. (×2) Insulate the edges so that the surface
and edges of the hanger brackets cannot be seen.

6. 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 sometimes.〉
〉〉
〉
(When using a heat pump, the temperature of the gas piping can
reach up to approximately 120°C, so use insulation which is suf-
ficiently resistant.)
〈
〈〈
〈
Also, in cases where the temperature and humidity of the
refrigerant piping sections might exceed 30°C or RH80%,
reinforce the refrigerant insulation. (20 mm or thicker) Con-
densation may form on the surface of the insulating material.
〉
〉 〉
〉
〈
〈〈
〈Before refrigerant piping work, check which type of refrig-
erant is used. Proper operation is not possible if the types
of refrigerant are not the same.〉
〉〉
〉
CAUTION
•Use a pipe cutter and flare suitable for the type of refrig-
erant.
•Apply ester oil or ether oil around the flare portions
before connectiong.
•To prevent dust, moisuture 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 refrig-
erant to get mixed into the refrigerant circuit, such as air,
etc. If any refrigerant gas leaks while working on the
unit, ventilate the room thoroughly right away.
•The outdoor unit is charged with refrigerant.
•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.
•To prevent flare nut cracking and gas leaks, be sure to use
both a spanner and torque wrench together, as shown in the
drawing below, when connecting or disconnecting pipes to/
from the unit.
•Refer to the Table 2 for the dimensions of flare nut spaces.
•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.
•Ventilate if refrigerant gas leaks while performing work.
Ta b l e 2
NOTE
The flare nuts used must be those included with the
main body.
CAUTION
Over-tightening may damage the flare and cause a refriger-
ant leakage.
Use “Tabel 3 ”as a reference if a torque wrench is not available.
Once work is complete, make sure there is no gas leaking. As
the flare nut is tightened with the wrench, the torque will sud-
denly increase. From that position, tighten the nut to the angle
shown on “Tabel 3 ”.
•After checking the pipe-connection for gas leakage, be sure
to insulate the liquid and gas piping, referring to the figure
below.
•Wrap the sealing pad (accessory) only around the insulation
for the joints on the gas piping side.
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.
NOTE
•Attached piping is needed for connecting gas piping of
FXMQ200 ·250MVE. Use attached piping according to the
size of the piping to be connected.
When connecting the included piping, use the included pip-
ing flange hex bolts (2) and spring washers (2).
•Connect refrigerant piping and branching according to the
attached installation manuals that come with the outdoor
unit.

CAUTION
CAUTION TO BE TAKEN WHEN BRAZING REFRIGER-
ANT 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 extremely harmful infulence on refrigerant piping
sysems. For instance, if the chlorine based flux is used, it
will cause pipe corrosion or, in particular, if the flux contains
fluorine, it will damage the refrigerant oil.)
•Before brazing local refrigerant piping, nitrogen gas shall be
blown through the piping to expel air from the piping.
If your 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, con-
nect the indoor unit with a flared or a flanged connection.
•Nitrogen should be set to 0.02 Mpa (0.2 kg/cm2) with a pres-
sure-reducing valve if brazing while inserting nitrogen into
the piping.
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:

7. DRAIN PIPING WORK
〈〈
〈〈〈〈
〈〈Rig the drain pipe as shown below and take measures
against condensation. Improperly rigged piping could lead
to leaks and eventually wet furniture and belongings.〉〉
〉〉〉〉
〉〉
〈〈
〈〈〈〈
〈〈Insulate the drain hose inside the building.〉〉
〉〉〉〉
〉〉
(1) Carry out the drain piping.
•Keep piping as short as possible and slope it downwards
so that air may not remaine trapped inside the pipe.
•Keep pipe size equal to or greater than that of the con-
necting pipe (Vinyl pipe of 25 mm nominal diam. and
32 mm outer diam.).
•Use the attached drain hose and clamp.
Tighten the clamp firmly.
•Insulate the clamp metal with the sealing pad.
•
There is negative pressure inside the unit relative to atmo-
spheric pressure when the unit is running, so be sure to
provide drain frap on the drain outlet. (See the figure)
•In order to prevent foreign matter from building up
inside the piping, you should avoid curves as much
as possible, and arrange so the trap can be cleaned.
NOTE
• If converging multiple drain pipes, install according to the pro-
cedure shown below. (Install a drain trap for each indoor unit.)
•A drain trap need not be installed.
•The diameter of the piping is the same as that of the con-
necting pipe (PS1B), and should be kept equal to or
greater than that of the connecting pipe.
(2) After piping work is finished, check drainage flows
smoothly.
•Add approximately 1 liter of water slowly from the air inlet
and check drainage flow.
•
Open the water supply port, add appximately 1 liter of water
slowly into the drain pan and check drainage flow.

CAUTION
•Be sure to attach the sealing material or putty (field supplied)
to hole of wiring to prevent the infiltration of water as well as
any insects and other small creatures from outside. Other-
wise a short-circuit may occur inside the electric parts box.
•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 50mm, otherwise electrical noise (external static) could
cause mistaken 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 gauge 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:
131N·cm ±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, screws
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 ground-
ing terminal. Looseness in the connection may deteriorate
protection.
4. Outside of the unit, keep transmission wiring at least 50 mm
away from power supply wiring. The equipment may mal-
function if subjected to electrical (external) noise.
5. For remote controller wiring, refer to the “INSTALLATION
MANUAL OF REMOTE CONTROLLER”attached to the
remote controller.
6. Never connect power supply wiring to the terminal
block for remote controller wiring. A mistake of the sort
could damage the entire system.
7. Use only specified wire and tightly connect wires to termi-
nals. Be careful wires do not place external stress on termi-
nals. Keep wiring in neat order and so as not to obstruct
other equipment such as popping open the electric parts
box lid. Make sure the lid closes tight. Incomplete connec-
tions could result in overheating, and in worse case, electric
shock or fire.
