HITACHI floor console: 22 dB(A) at its lowest, no pump, four sizes up to 18,000 BTU/h

Hitachi calls it the airHome Floor. It attaches to the wall or stands on the supplied base, and reaches only 219 mm into the room. Three facts set it apart: four published sizes, 7,000 to 18,000 BTU/h; no condensate pump, the water runs down by gravity; and no quieter airHome Multi head at the lowest speed: 22 dB(A).

01 · Sound

22 dB(A): the lowest sound figure in the whole airHome Multi family.

Pick a size, a mode and a speed: the needle follows Hitachi’s brochure figures. Below, the lowest figure printed for each head type.

airHome Multi brochure. The ducted head is measured with no duct, and Hitachi prints four values for its five speeds. The brochure does not print the sound test conditions for the other heads.

02 · Condensate

No pump: the water has to run downhill on its own.

On the “included drain pump” row, Hitachi’s technical guide answers no for the console. The ducted head has one, and so does the mini-cassette according to the technical guide; the console drains its water through a 16 mm drain, by gravity.

What it changes in your home

With no pump, the water must run downhill all the way from the console to its outlet: its route counts as much as the line route when choosing the location. We plan it during the visit, before proposing a console.

03 · Outdoor unit

On which RAM-G, and with which adaptor.

The 18,000 console has a 1/2 in. gas line; the RAM-G24N3HAA only has 3/8 in. ports. Hitachi covers that case with an adaptor shipped with the outdoor unit. Pick a size.

Combination tables 3.5 to 3.7 and section 13.1 of Hitachi’s technical guide: “Make sure to attach the seal when using the adaptors.” Hitachi publishes no rule assigning each head to a port. The four consoles in our store, 7,000 to 18,000, are all in the RAM-G24N3HAA table, the only outdoor unit whose three certificates are all ENERGY STAR Cold Climate (US market).

Four consoles, one body.

Same 750 × 590 × 219 mm body and same 38 W motor for all four. The 18,000 stands apart: 1/2 in. gas line, more airflow, a little more sound.

05 · Mounting

On the wall or on its base, supplied with the unit.

Two mountings published by Hitachi, a 219 mm depth, and one dimension to confirm: Hitachi prints 750 × 590 × 219 mm, but its dimensioned drawing does not let us check which one is the height; we check it on the delivered unit.

Attached to the wall, according to Hitachi, which publishes neither the mounting height nor the wall bracket details.

“Can be attached on the wall or on a standing base (supplied with the unit).”

Height or width: to check on the unit

Hitachi prints 750 × 590 × 219 mm in height × width × depth order, but its guide’s dimensioned drawing does not let us check which of the first two is the height. Only the depth, 219 mm, is certain: we measure the delivered unit before setting the location.

What Hitachi prints for the console, word for word where it helps.

  • R-32
    A leak alarm on the unit

    “Built-in gas leakage sensor, alarm light and buzz sound”, Hitachi writes for the console. For the other heads, it mentions a built-in sensor and an optional receiver kit with an alarm.

  • PM2.5
    Two filters

    A stainless steel pre-filter and a PM2.5 active carbon filter. For the console, Hitachi publishes no efficiency percentage and no cleaning interval.

  • RC-BGH1FB0N · RC-BGH1FD0N
    Two possible remotes

    The technical guide lists these two models for all four sizes. It does not show with certainty which one is supplied, and does not say which one is in French: we state it in your quotation.

  • SPX-WFA01
    Optional Wi-Fi

    airCloud Go adapter, optional per the brochure.

  • 38 W
    Fan and current

    38 W motor; the head draws 0.30 A (7,000 and 9,000) to 0.40 A (18,000).

  • airHome Floor
    Hitachi’s name

    Hitachi calls it airHome Floor and speaks of an “elegant console design”. “Floor console” is our name for it.

07 · Frequently asked questions

Your questions about the Hitachi console.

Not in Hitachi’s brochure or data sheets, which stop at 18,000 BTU/h. The technical guide’s compatibility list names a RAF-FJ24QHAA, with no data sheet or capacity published: it is not in our store. For a room that needs more, the mini-cassette goes up to 20,500 BTU/h per the brochure, and the ducted head up to 24,000 BTU/h.
