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.〉
English
01_EN_3P086156-8X.fm Page 5 Wednesday, April 8, 2009 3:56 PM
(When using a heat pump, the temperature of the gas piping
can reach up to approximately 120°C, so use insulation which is
sufficiently 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) Condensation may form on the surface of the insulating material.〉
〈Before ringging tubes, check which type of refrigerant is
used. Proper operation is not possible if the types of refrigerant are not the same.〉
• Wrap the sealing pad (accessory) only around the insulation
for the joints on the gas piping side.

CAUTION
• Use a pipe cutter and flare suitable for the type of refrigerant.
• Apply ester oil or ether oil around the flare portions
before connecting.
• 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 freezing cycle, 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.
• Refer to the Table 3 for the dimensionons of flare not 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 3 for tightening torque.
Overtightening may damage the flare.
• Check the pipe connector for gas leaks, then insulate it as
shown in the drawing.
• Wrap only the gas line side with the sealing pad. Bend the pad
over the insulation for fitting (union) from above.
Ester oil or ether oil.
Liquid pipe
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.
CAUTION
CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING
Do not use flux when brazing refrigerant piping. Therefore, use
the phosphor copper brazing filler metal (BCuP-2: JIS Z 3264/
B-Cu93P-710/795: ISO 3677) 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, connect the indoor unit with a flared or a flanged connection.
• Nitrogen should be set to 0.02 MPa with a pressure-reducing
valve if brazing while inserting nitrogen into the piping.

Use “ Table 4 ” 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 suddenly increase. From that position, tighten the nut to the angle
shown on “ Table 4 ”.
• Make absolutely sure to execute heat insulation works on the
pipe-connecting section after checking gas leakage by thoroughly studying the following figure and using the attached
heat insulating materials for fitting. (Fasten both ends with
the clamps (accessory).)

• You can temporarily hang the electric parts box of the unit
from the position shown in the figure below. Use according to
the type of work.
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. Otherwise 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 lid 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.

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 grounding terminal. Looseness in the connection may deteriorate
protection.
4. Out side of the unit, keep transmission wiring at least 50 mm
away from power supply wiring. The equipment may malfunction 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.
