The exclusive knowledge and technology are required for installation work. Do not perform installation by yourself. If an incomplete installation is performed, a fire, electric shock, injury, or water leakage may be caused. Be sure to use the products sold separately which are specified by us. For the products sold separately, be sure to use those specified by us. Otherwise, a fire, electric shock, or water leakage may be caused. [. . . ] Be sure to perform vacuuming for suction gas side, discharge gas side and liquid side. · Be sure to perform vacuuming from both suction gas side, discharge gas side and liquid side. · Be sure to use a vacuum pump with counter-flow preventive function so that oil in the pump does not back up in the pipe of the air conditioner while the pump stops. (If oil in the vacuum pump enters in the air conditioner with R410A refrigerant, a trouble is caused in the refrigerating cycle. ) Connected to indoor unit Main pipe Packed valve fully closed (Suction gas side) Outdoor unit LowHighpressure pressure gauge gauge VL VH Gauge manifold Detailed drawing of packed valve Suction gas side service port To gauge manifold Discharge gas side service port Discharge gas side ball valve Liquid side service port Liquid side packed valve To outdoor unit Piping at site To outdoor unit Piping at site Suction gas side packed valve or ball valve Brazed Service port Fully closed Service port P To outdoor unit Fully closed Piping at site Ball valve fully closed (Discharge gas side) Vacuum pump Packed valve fully closed (Liquid side) · Use a vacuum pump having a high vacuuming degree (below ­755mmHg) and a large exhaust gas amount (over 40L/minute). · Perform vacuuming for 2 or 3 hours though time differs due to pipe length. In this time, check all packed valves at suction gas, discharge gas, and liquid sides are fully closed. · If vacuuming valve amount is not decreased to below ­755mmHg even after vacuuming for 2 hours or more, continue vacuuming for 1 hour or more. If ­755mmHg or less cannot be obtained by 3 hours or more vacuuming, check the leaked position. · When vacuuming valve reached to ­755mmHg or less after vacuuming for 2 hours or more, close valves VL and VH of the gauge manifold fully, stop the vacuum pump, leave it as it is for 1 hour, and then check the vacuuming degree does not change. If it changed, there may be a leaked position. · After the above procedure of vacuuming has finished, exchange the vacuum pump with a refrigerant cylinder and advance to the additional charging of refrigerant. 39 Outdoor Unit / INSTALLATION MANUAL [ VOLUME-1 ] Addition of refrigerant After vacuuming work, exchange the vacuum pump with the refrigerant bomb and then start the additional charging work of refrigerant. Calculation of additional refrigerant charge amount Refrigerant charge amount at shipment from the factory does not include the refrigerant for pipe at the local site. · For wiring of power supply in the indoor unit, refer to the Installation Manual of each indoor unit. · Never connect the 220­240V power to the terminal block (U1, U2, U3, U4, U5, U6) for control wires. (Trouble is caused. ) · Arrange the wires so that the electric wires do not come to contact with high-temperature part of the pipe; otherwise coating melts and an accident may be caused. · After connecting wire to the terminal block, take off the trap and then fix the cable with wire clamp. · Store wiring system for control and refrigerant piping system in the same line. · Do not turn on power of the indoor unit until vacuuming of the refrigerant pipe will finish. · For wiring of the power supply of the indoor unit and the inter-unit cabling between indoor and outdoor units, refer to the Installation Manual of indoor unit. 42 Outdoor Unit / INSTALLATION MANUAL [ VOLUME-2 ] 6 ELECTRIC WIRING Power supply specifications · Power supply specifications of outdoor unit Select the power supply cabling and fuse of outdoor unit from the following specifications: wire 5-core, in conformance with Design 60245 IEC 66 Electrical wiring design 3-phase 50Hz 380-415V Earth Earth leakage breaker hand switch Outdoor power source · Power supply specifications of indoor unit Pull box Indoor power source Single phase 50Hz 220-240V Earth leakage breaker power switch FS unit FS unit FS unit FS unit FS unit FS unit FS unit FS unit · Unit capacities and power supply wire sizes (Reference) Power supply wiring Model Wire size MMY-MAP0801FT8 MMY-MAP1001FT8 MMY-MAP1201FT8 3. 5 mm² (AWG #12) Max. 27 m Field fuse 30 A 30 A 30 A · Determine the wire size for indoor unit according to the number of connected indoor units downstream. · Observe local regulation regarding wire size selection and installation. 43 Outdoor Unit / INSTALLATION MANUAL [ VOLUME-2 ] Design of control wiring n Outdoor unit Model name MMYMAP0801FT8 MAP1001FT8 MAP1201FT8 Nominal voltage (V-Ph-Hz) 400-3-50 400-3-50 400-3-50 Voltage range Min. 457 457 457 Compressor RLA 5. 2 + 5. 2 6. 5 + 6. 5 9. 5 + 9. 5 LRA -- -- -- Fan Motor kW 0. 60 0. 60 0. 60 FLA 1. 0 1. 1 1. 1 MCA 20. 0 22. 5 24. 5 Power Supply MOCP 30 30 30 ICF -- -- -- Legend Power supply single phase 220-240V 50Hz (Open) Earth MCA MOCP ICF RLA LRA FLA kW : Minimum Circuit Amps : Maximum Overcurrent Protection (Amps) : Maximum Instantaneous Current Flow Start : Rated Load Amps : Locked Rotor Amps : Full Load Amps : Fan Motor Rated Output (kW) [Central remote controller] (Option) TCB-SC642TLE (For Line 64) Transmission wire for control between outdoor unit and indoor unit NOTE : RLA is based on the following conditions.
