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 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 refrigerant piping work, check which type of refrigerant is used. Proper operation is not pos-
sible if the types of refrigerant are not the same.〉
CAUTION
• Use a pipe cutter and flare suitable for the type of refrigerant.
• Apply ester oil or ether oil around the flare section before connecting.
• 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 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
thoroughly right away.
•The outdoor unit is charged with refrigerant.
•Use copper alloy seamless pipes (ISO 1337).
•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 Fig. 10)
•Refer to “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 Fig. 11)
NOTE
•Use the flare nut included with the unit main body.
CAUTION
Do not let oil get on the screw holders on the dressing board.
Oil can weaken the screw holders.

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:
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 influence on refrigerant piping systems. 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 you 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. (Refer to Fig. 12)

7. DRAIN PIPING WORK
(1) Carry out the drain piping.
•Make sure piping provides proper drainage.
•You can select whether to bring the drain piping our from the rear right, right, rear left, or left. For rear right-
facing and right-facing situations, refer to “6. REFRIGERANT PIPING WORK” on page 9 for rear left-facing
and left-facing situations. (Refer to Fig. 18)
•When setting piping facing left, move the rubber stopper and insulation which are attached to the drain pipe
connection hole on the left side of the indoor unit to the right-side drain pipe connection hole.
When doing this, insert the rubber stopper all the way in to prevent a water leakage.
•Make sure the pipe diameter is the same or bigger than the branch piping. (vinyl-chloride piping, nominal
diameter 20 mm, external diameter 26 mm)
•Make sure the piping is short, has at least a 1/100 slope, and can prevent air pockets from forming.
(Refer to Fig. 19)
CAUTION
Water accumulating in the drain piping can cause the drain to clog.
•Be sure to use the included drain hose (1) and clamp (2).
Also, insert the drain hose completely into the drain socket, and securely attach the clamp bracket inside
the gray tape area on the inserted tip of the drain hose. (Refer to Fig. 20)
Screw the screws on the clamp bracket until there is 4 mm left. (Pay attention to the direction of the attach-
ment to prevent the clamp bracket from coming into contact with the suction grille.)
