Before ordering

The right part, checked before it reaches you

What we check before selling

  • The refrigerant: the PMBL5620 Y-branch is an R-410A part; an R-32 Multi F MAX calls for the ARBLN03321.
  • The number of ports on the branch box, for your number of rooms.
  • The drain pan heater: never for a KUMXA, which already has one.
  • The rating of the ANEH electric heat kit, 3 to 20 kW.
  • The 3x3 grille: LG lists it as included with the KSSCA421A system.
  • Numbers with no LG source: PQCA0, and the name “CRC2+”.

Frequently asked questions

What people ask us most

Does the PMBL5620 Y-branch fit my R-32 Multi F MAX?
No. LG lists it for R-410A Multi F MAX units. On an R-32 Multi F MAX with two branch boxes, LG requires the ARBLN03321 Y-branch.
Do I need the drain pan heater for an LGRED° unit?
No. LG installs it at the factory on the LGRED° R-32 multi-zone units KUMXA181A and KUMXA361A. It is optional on standard Multi F MAX units such as the KUMXB601A.
Is the grille included with the cassette?
LG lists the PT-AAGW0 grille as included with the 3x3 KSSCA421A system. We check before ordering one separately. The R-32 2x2 cassettes take the PT-QAGW0.
Which wall controller should I choose?
LG lists the Standard III PREMTB101, the Deluxe PREMTA201 and the MultiSITE CRC family with its R-32 wall units, and the Standard III with the R-32 air handler. For a cassette, ducted unit or console, we confirm compatibility.
What is the PQCA0 kit?
We found no LG source for this number. We confirm the part with LG before selling it.
