S.D. S 2. M-NET control DATA U10 2-3-3. Ensuring proper power supply to System controller The power to System controller (excluding LM-AP) is supplied via M-NET transmission line. M-NET transmission line at TB7 side is called Central control transmission line while one at TB3 side is called Indoor-Outdoor transmission line. There are 2 ways to supply power to the System controller . A) Connecting to TB3 of the Outdoor unit and receiving power from the Outdoor unit.
PAGE 11
2. M-NET control DATA U10 S.D. S 2-3-4. Power supply to LM-AP 1-phase 208-230V AC power supply is needed. The power supply unit PAC-SC51KUA is not necessary when connecting only the LM-AP. Yet, make sure to change the power supply changeover connector CN41 to CN40 on the LM-AP. 2-3-5. Power supply to expansion controller 1-phase 100-240VAC power supply is needed. The power supply unit PAC-SC51KUA is not necessary. The expansion controller supplies power through TB3, which equals 6 indoor units.

3. Piping Design DATA U10 S.D. S 3-3. Refrigerant charging calculation 3-3-1. PUMY-P-NHMU Original refrigerant charge for PUMY-P-NHMU is 8.5 kg [18.75 lbs], including 3 kg [106 oz] for 50 m [164 ft.] total extended piping length use. Thus, there is no need to charge additional refrigerant to the system if the total extended piping length is 50 m [164 ft.] or less. If the total extended piping length is over 50 m [164 ft.], calculate the additional refrigerant using following procedure.
PAGE 25
3. Piping Design DATA U10 Additional refrigerant charge Refrigerant for the extended piping is not included in the outdoor unit when the unit is shipped from the factory. Therefore, charge each refrigerant piping system with additional refrigerant at the installation site. In addition, in order to carry out service, enter the size and length of each liquid pipe and additional refrigerant charge amounts in the spaces provided on the “Refrigerant amount” plate on the outdoor unit.

S.D. S 5. Installation information DATA U10 5-1-6. Unit installation Your local distributor or a qualified technician must read the Installation Manual that is provided with each unit carefully before performing installation work. Consult your local distributor or a qualified technician when installing the unit. Improper installation by an unqualified person may result in water leakage, electric shock, or fire. Ensure there is enough space around each unit. 5-1-7.

5. Installation information DATA U10 5-3. Precautions for Outdoor unit/Heat source unit Outdoor unit with salt-resistant specification is recommended to use in a place where it is subject to salt air. Even when the unit with salt-resistant specification is used, it is not completely protected against corrosion. Be sure to follow the directions or precautions described in Instructions Book and Installation Manual for installation and maintenance.

6. Caution for refrigerant leakage DATA U10 The installer and/or air conditioning system specialist shall secure safety against refrigerant leakage according to local regulations or standards. The following standard may be applicable if no local regulation or standard is available. 6. Caution for refrigerant leakage R410A refrigerant is harmless and incombustible. The R410A is heavier than the indoor air in density. Leakage of the refrigerant in a room has possibility to lead to a hypoxia situation.
