Common Questions
What does the LG KUSAP361A pair with?
LG rates KUSAP361A only with KNSAP361A (indoor unit) or KSSAP361A (system). Other combinations are not AHRI-matched and are not covered by the LG warranty.
What does the KUSAP361A replace?
KUSAP361A is LG's current R32 model in this position and replaces the discontinued LSU363HLV3. R32 and R-410A equipment cannot be mixed — replace the indoor and outdoor unit together.
What power does the KUSAP361A 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 KUSAP361A?
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 2, 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 KUSAP361A is identical across all name variations.
