Page 5 [1] Warning for service (1) Do not alter the unit. (2) For installation and relocation work, follow the instructions in the installation manual and use tools and pipe components speciﬁ cally made for use with refrigerant speciﬁ ed in the outdoor unit installation manual. (3) Ask a dealer or an authorized technician to install, relocate and repair the unit.
Page 6: Cautions For Service
[2] Cautions for service (1) Perform service after recovering the refrigerant left in unit completely. (2) Do not release refrigerant in the air. (3) After completing service, charge the cycle with specified amount of refrigerant. (4) If moisture or foreign matter might have entered the refrigerant piping during service, ensure to remove them. [3] Additional refrigerant charge When charging directly from cylinder (1) Check that cylinder for R454B on the market is a syphon type.
Page 7 [4] Cautions for unit using R454B refrigerant Basic work procedures are the same as those for conventional units using refrigerant R410A. However, pay careful attention to the following points. (1) Information on servicing (1-1) Checks on the Area Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, safety checks are necessary to ensure that the risk of ignition is minimized.
Page 8 (2) Repairs to Sealed Components Sealed electrical components shall be replaced. (3) Repair to intrinsically Safe Components Intrinsically safe components must be replaced.

M-NET WIRING METHOD Points to notice: (1) Outside the unit, transmission wires should stay away from electric wires in order to prevent electromagnetic noise from making an influence on the signal communication. Place them at intervals of 5 cm [2 in.] or more. Do not put them in the same conduit tube.
Page 25 8-2-1. M-NET address setting In A-control models, M-NET address and refrigerant address should be set only for the outdoor unit. Similar to City Multi series, there is no need to set the address of outdoor unit and remote controller. To construct a central control system, the setting of M-NET address should be conducted only upon the outdoor unit.
