Overview

LG ARNU243M2A4 is a 24,200 Btu/h ceiling-concealed mid/high-static ducted indoor unit for LG Multi V VRF systems

From the LG submittal: rated 27,300 Btu/h in heating. Power is 208-230V, 1-phase (indoor units are powered independently of the outdoor unit on Multi V systems).

What this indoor unit needs

  • Outdoor unit: any LG Multi V outdoor unit at matching voltage (208-230V). LG allows total connected indoor capacity up to about 120% of the outdoor unit's rated capacity — see the combination data manual under Documentation for the exact table.
  • Heat recovery: on a heat-recovery system this indoor unit connects through a PRHR branch-distribution unit; on a heat-pump system it connects directly.
  • Controls: compatible with LG's wired and central controllers (PREMTB, MultiSITE™ CRC, AC Smart); a controller is not included.

Installation must follow the LG installation manual linked under Documentation, by a contractor trained on LG VRF equipment. LG VRF systems carry their own limited warranty, separate from the residential line.

Compatible Units

LG approves ARNU243M2A4 only in the combinations below (per the LG engineering manual and submittal). Mixing it with any other outdoor or indoor unit is not an AHRI-rated match. Ask the parts desk if your existing equipment isn't listed.

  • Any LG Multi V outdoor unit at 208-230V (capacity ratio up to ~120%)

Common Questions

What does the LG ARNU243M2A4 pair with?

LG rates ARNU243M2A4 only with Any LG Multi V outdoor unit at 208-230V (capacity ratio up to ~120%). Other combinations are not AHRI-matched and are not covered by the LG warranty.

What power does the ARNU243M2A4 need?

208-230V, 1-phase. Minimum circuit ampacity and maximum overcurrent protection are listed in the Specifications table above and on the LG submittal under Documentation; size the breaker and wire to those values and local code.

Is the submittal sheet and installation manual available for ARNU243M2A4?

Yes — the LG submittal data sheet, engineering manual, installation manual and warranty document are all linked under Documentation on this page and can be downloaded without an account.

Is the stock number on this page real?

Yes — it's the live count from our own shelf, not an availability estimate. If it says 6, that's how many are physically here. When it hits zero, this page says so.

Is this a genuine LG unit, or aftermarket?

Genuine LG OEM equipment — not an aftermarket substitute.

I see this listed under a different name on other sites. Is it the same part?

Yes — manufacturers and distributors sometimes use different brand names or legacy labels for the same part number. Part number ARNU243M2A4 is identical across all name variations.

What's the warranty on this part?

Warranty terms vary by manufacturer. Contact us with your order number for details specific to this part.

How fast does this ship?

In-stock items ship the same business day on orders placed before 1pm ET, Monday–Friday. Standard ground delivers to most of the continental US in 2–5 business days.

Does everything ship UPS or FedEx Ground?

Most orders ship UPS or FedEx Ground. A small number of large or heavy parts across the catalog ship by truck freight instead — that's still free, and we reach out to arrange a delivery window before those orders leave the warehouse.
