WARNING
●Be sure to comply with local codes on running the wire from the indoor unit to the outdoor unit (size of wire and wiring method, etc.).
●Each wire must be firmly connected.
●No wire should be allowed to touch refrigerant tubing, the compressor, or any moving part.
●Be sure to connect power wires correctly matching up numbers on terminals of the outdoor unit and respective indoor units A – D.
CAUTION
●Be sure to connect the power supply line to the outdoor unit as shown in the wiring diagram. The indoor unit draws its power from the outdoor unit.
●Do not run wiring for antenna, signal, or power lines of television, radio, stereo, telephone, security system, or intercom any closer than
1 meter from the power cable and wires between the indoor and outdoor units. Electrical noise may affect the operation.
3 indoor units with SAP-CMRV1936
WARNING
●To avoid the risk of electric shock, each air conditioner unit must be grounded.
●For the installation of a grounding device, please observe local electrical codes.
●Grounding is necessary, especially for units using inverter circuits, in order to release charged electricity and electrical noise caused by high tension.
Otherwise, electrical shock may occur.
●Place a dedicated ground more than 2 meters away from other grounds and do not have it shared with other electric appliances.
