6. REFRIGERANT PIPING WORK
For refrigerant piping of outdoor unit and BP unit, see the installation manuals attached to the out-
〈〈〈〈
door unit and BP 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) Condensate may form on the surface of the
insulating material.〉
〈Be sure to check the type of refrigerant to be used before doing any work. (Using an incorrect refrigerant will
prevent normal operation of the unit.)〉
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, 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, ventilate the room thoroughly right away.

CAUTION
For local insulation, be sure to insulate local piping all the way into the pipe connections inside the machine.
Exposed piping may cause condensation or burns on contact.
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.

7. DRAIN PIPING WORK
1. Rig drain piping (Refer to Fig. 10, Fig. 11)
• As for drain work, perform piping in such a manner that water can be drained properly.
As for drain piping, the connection can be made from three different directions.
• Employ a pipe with either the same diameter or with the diameter larger (excluding the raising section)
than that of the connecting pipe (PVC pipe, nominal diameter 25 mm, outside diameter 32 mm).
• Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent air pockets
from forming.
• If the drain pipe cannot be sufficiently set on a slope, execute the drain raising piping.
• To keep the drain pipe from sagging, space hanging wires every 1 to 1.5 m.

could cause short circuits in the control box.)
• Outside the machine, separate the weak wiring (remote controller cord) and strong wiring (interunit,
ground, and other power wiring) at least 50 mm so that they do not pass through the same place together.
Proximity may cause electrical interference, malfunctions, and breakage.
• Do not connect wires of different gauge to the same power supply terminal. (Looseness in the connection
may cause overheating.) (Refer to Fig. 20)
• Observe the notes when wiring to the terminal block for wiring the units.
(Use a round crimp-style terminal with insulation sleeve for connection to the terminal block for wiring the
units. In case it cannot be used due to unavoidable reasons, connect wires of the same gauge to the both
side as shown in Fig. 20.)

Follow the instructions below if the wiring gets very hot due to slack in the power wiring.
• In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires so
that outside forces are not applied to the terminals.
• 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 screw are tightened too hard, screws might be damaged.
• Refer to the table below for the tightening torque of the terminal screws.
Tightening torque (N·m)
Terminal block for remote controller 0.79 to 0.97
Terminal block for wiring the units 1.18 to 1.44
