2. BEFORE INSTALLATION When unpacking the indoor unit or moving the unit after unpacked, hold the hangers (4 places) and do not apply force to other parts (particularly refrigerant piping, drain piping and resin parts). • Make sure to check in advance that the refrigerant to be used for installation work is R410A. (The air conditioner will not properly operate if a wrong refrigerant is used.) •... - Page 5 • Confirm if a decoration panel shown in the Table 1 is prepared and meets your model.

2. Items to be checked at delivery Check Items to be checked column Have you carried out field setting? (if necessary) Are the control box lid, resin cover, the air filter and the suction panel attached? Does the cool air discharge during the cooling operation and the warm air discharge during the heating operation? Does the indoor unit makes unpleasant sound of air charge? Have you explained how to operate the air conditioner showing the operation manual to the customer? - Page 7 Required installation space (mm) 355 or more 100 or 100 or more more 1500 or 1500 or Floor level more more 1000 or more 2500 or more Fig. 1 from the furniture from the floor level CAUTION • Install the indoor and outdoor units, power supply wiring, remote controller wiring and transmission wiring at least 1 meter away from televisions or radios to prevent image interference or noise.

(3) Install the hanging bolts. • Use M8 or M10 bolts for hanging the indoor unit. Use hole-in-anchors for the existing bolts and embedded inserts or foundation bolts for new bolts, and fix the indoor unit firmly to the building so that it may withstand the mass of the unit. In addition, adjust the distance from the ceiling in advance. - Page 10 [In case of existing ceiling] • Cut off the guides from the installation pattern paper (5) and place the guide to the indoor unit bottom. Adjust the unit height from the floor level so that the ceiling lower surface and the notch lower part will match together.

CAUTION • Install the indoor unit leveled. If the indoor unit is inclined and the drain piping side gets high, it may cause malfunction of a float switch and results in water leakage. • Attach nuts on the upper and lower side of hanger. If there is no upper nut and the lower nut is over-tightened, the hanger and the top plate will deform and cause abnormal sound. - Page 12 Table 2 Dimension for processing Piping size (mm) Tightening torque (N·m) Flare shape flare A (mm) φ 6.4 15.7 ± 1.5 8.9 ± 0.2 φ 9.5 36.3 ± 3.6 13.0 ± 0.2 R0. 4-0.8 φ 12.7 54.9 ± 5.4 16.4 ± 0.2 φ...

2. Do not use flux when brazing refrigerant piping. Use phosphor copper brazing filler metal (BCuP-2: JIS Z 3264/B-Cu93P-710/795: ISO 3677) that does not require flux. (If chlorinated flux is used, the piping will be corroded and, in addition if fluorine is contained, the refrig- erant oil will be deteriorated and the refrigerant circuit will be affected badly.) 3. - Page 15 CAUTION • Do not tighten the metal clamp (2) with the torque more than the specified value. The drain hose (1), the socket or the metal clamp (2) may be damaged. • Wrap the vinyl tape around the end of the metal clamp (2) so that the sealing material (Large) (10) to be used at the next process may not be damaged with the clamp end or bend the tip of the metal clamp (2) inward as shown.
- Page 16 CAUTION • To avoid the attached drain hose (1) getting excessive force, do not bend nor twist it. It may cause water leakage. • In case of centralized drain piping, carry out piping work according to the procedure shown in the follow- ing Fig.
- Page 17 [When the electric wiring work is not finished] • The electric wiring works (including earthing) must be carried out by a qualified electrician. • If a qualified person is not present, after the electric wiring work is finished, check the drainage accord- ing to the method specified in [When the electric wiring work is finished].

(3) Sweating may occur and result in water leakage. Therefore, make sure to insulate the following 2 places (drain piping and drain sockets that laid indoors). After drainage is checked, put the attached insulation piping cover (13) referring to Fig. 17, and insulate the drain hose (1) and the metal clamp (2) with the attached sealing material (Large) (10) referring to Fig. - Page 19 • Carry out installation and wiring of the remote controller according to the “installation manual” attached to the remote controller. • Do not touch the Printed Circuit Board assembly. It may cause malfunction. 8-2 ELECTRICAL CHARACTERISTICS Indoor units Power supply Fan motor Model Volts Voltage range FXCQ20AVEB 0.046 FXCQ25AVEB 0.046 FXCQ32AVEB 0.046 FXCQ40AVEB 0.046 FXCQ50AVEB 0.046 Max.

- Page 21 • After connecting the wiring, make sure to stick the sealing material (12) to the wiring penetrating hole. (Refer to Fig. 19) (It is to prevent water from entering into the indoor unit.) CAUTION • Never connect the power supply wiring to the terminal block for remote controller/transmission wiring (X1M). If may damage the total system.
