[Outdoor unit installation]
¥ The pipe connection ports of the outdoor unit and connectable indoor units are shown below. (Connection of the compressors
is as shown below.)
AM-70QH4
¥ To the outdoor unit, up to three indoor units can be connected until the total value of each unit's capacity from 5.0kW to 11.0kW.
AM-80QH4
¥ To the outdoor unit, up to four indoor units can be connected until the total value of each unitÕs capacity reaches 12.0kW.
However, install indoor units so that total capacity of Indoor unit 1 and Indoor unit 2 and total capacity of Indoor unit 3 and Indoor
unit 4 are approached. For example, when two 2.5kW units and two 3.5kW units are to be connected, connect as shown below.
¥ Connect 3 or more indoor units. If only two units are to be connected, connect them as Indoor unit 1 and Indoor unit 2 or Indoor unit
3 and Indoor unit 4. However, when two 3.5kW units are connected or when one 2.5kW unit and one 4kW unit are connected,
capacity may be less than indicated capacity.
