A BP unit is an innovative

development which allows Super

Multi Plus outdoor units to be

connected to a wide range of

different indoor unit types. A BP

unit has the ability to precisely

vary refrigerant volume to meet

the cooling requirements of

individual room spaces. The

improved BP unit is easier to

disassemble, making repairing

and recycling simpler.

Optional REFNET joint:

3 ports BPMKS967B3B

2 ports BPMKS967B2B

The REFNET joint both

reduces the amount of

work involved in

installation and

increases the reliability

of the system.

The outdoor unit and the BP units operate from separate single-phase power supplies, so no power supply wiring is needed

between them. The size of the wiring pipe from the outdoor unit to the BP units can be reduced, making installation easier.

Simplified electrical wiring connection

The outdoor unit’s heat exchanger fins are processed using a

special anticorrosion treatment. The surface is covered with a

thin acrylic resin layer to enhance the fins’ resistance to acid

rain and salt corrosion. A hydrophilic film layer also prevents

rust caused by the run off of water droplets. Additional

durability is provided by a rustproof steel sheet on the bottom

of the unit.

Durable outdoor unit

A single high-capacity outdoor unit can drive up to 8 indoor

units, making it powerful enough to air-condition a whole

residence. This powerful unit can be easily installed on a

balcony with its slimline design, which measures (H) 1,345 x

(W) 900 x (D) 320 mm.

Space saving

A maximum total piping length of 145 m offers flexibility in the choice of

installation positions for the indoor units, and greatly simplifies system

planning.

The Super Multi Plus E Series is connectable to up to 8 indoor units. While the BP unit and the REFNET

joint make installation simple, long piping length and simplified wiring broaden design flexibility.

Thin refrigerant piping makes handling and connecting easier, resulting in significantly reduced installation time.

As many as 8 indoor units can be connected to a single outdoor unit
