[. . . ] Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device. volume of the indoor unit installed room (m³) Concentration limit (kg/m³) The concentration limit of R410A which is used in multi air conditioners is 0. 3kg/m³.

Selecting a Location for Installation CAUTION Check that it is installed at a place where flammable gas does not leak. If gas leaks and accumulates on surroundings of the unit, combustion may be caused. Otherwise, an accident such as falling may be caused. REQUIREMENT · Avoid a location where a machine is generating high frequency. · Using the air conditioner at a specific location where spray of oil (including machine oil) or steam is possible, salty location such as seaside, or place where gas sulfide generates such as hot spring may cause a trouble. · Avoid obstruction of inlet port and outlet port of the outdoor unit so there is no restriction of air flow. · Avoid to installing the air conditioner in a location where strong wind blows against the inlet or outlet port of the outdoor unit. · When using the air conditioner at the snow area, mount a snowfall frame or hood to the outdoor unit. For details, contact the dealer which you purchased the air conditioner. · Drain water from the outdoor unit to a place having good drainage. · Set TV or radio 1m or more apart from the main unit of air conditioner or remote controller. ELECTRIC WIRING WARNING Using the exclusive circuit, a person qualified for electrician shall work for the electric work in conformance with the regulations of the local electric company and the Installation Manual. If there is capacity shortage of the power circuit or incomplete electric work, a fire or electric shock is caused. For cabling, use the specified cables and connect them securely so that external force of cable does not transmit to the terminal connecting section. If connection or fixing is incomplete, a fire is caused. Be sure to connect the earth wire. Grounding work is necessary based upon a law. Do not connect earth wire to gas pipe, lightning rod, or earth wire of telephone. CAUTION Be sure to attach an earth leakage breaker; otherwise an electric shock may be caused. To Disconnect the Appliance from Main Power Supply. This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm. REQUIREMENT · Perform wiring of the power supply in conformance with the regulations of the local electric company. · 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 cables. (Trouble is caused. ) · Arrange the cables 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 cable to the terminal block, take off the trap and then fix the cable with cable 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 cabling 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. 87 9-1. Power Supply Specifications · Power supply specifications of outdoor unit Select the power supply cabling and fuse of outdoor unit from the following specifications: Cable 5-core, in conformance with Design 60245 IEC 66 9-2.
