Check air-conditioner model numbers and suffixes
A series name starts the search. Documents, comparisons and ordering need the complete identity of every unit. An extra letter can change the applicable evidence or features without being obvious in a shortened catalogue heading.
Perfera: distinguish RXM-A and RXM-A9
RXM-A and RXM-A9 are different outdoor references. Capacity and efficiency data must match the complete indoor/outdoor pairing. For replacement or extension, model references from the rating plate help with selection.
MHI: check W and W2 within the pair
For MHI ZS-W, W and W2 are part of the full outdoor model reference. Record indoor and outdoor units separately and use the matching combination table and energy documents. Equal capacity sizes alone do not establish interchangeability.
AY: retain feature variant and generation
MSZ-AY35VGK and MSZ-AY35VGKP differ in documented air purification. VGK2/VG2 are different model references again. Copy indoor model, outdoor model and full suffix from the quotation, nameplate or manufacturer document, and list alternatives separately.
Worked example: Check W, WF and W2 across two units
Wi-Fi is documented as optional for the SRK35ZS-W indoor unit and built in for the SRK35ZS-WF. Check the outdoor reference separately for the complete system. A sheet for SRC35ZS-W2 documents that pairing. If the quotation lists SRC35ZS-W, ask for confirmation of that exact pairing and its system data.

Frequently asked questions
- May a missing suffix be filled in?
- Resolve the suffix using a matching document or confirmation of the actual delivery model. Similar names, equal capacity and product photos are insufficient evidence.
