How to Locate a Pioneer Model Number or Serial NumberUpdated a year ago
Locating Model Numbers
Locating the Outdoor Unit Model Number of your Pioneer System
The model number on a Pioneer outdoor unit is almost always found on the gray colored nameplate/namebadge that is physically fixed onto the system, on the right hand side.
Locating the Indoor Unit Model Number of your Pioneer System
The indoor unit's model number is also located on the nameplate badge, but the location of the nameplate will vary depending on the type of indoor unit.
For wall-type units, it is also found on the right-hand side of the unit itself.
Locating Serial Numbers
Locating the Outdoor Unit Serial Number of your Pioneer System
Serial numbers for Pioneer systems are generally found on a white barcode sticker located somewhere on the unit.
In our previous example, the serial number can be easily found beneath the outdoor unit's nameplate.Just like the outdoor unit, the indoor unit's serial number is most often found beneath the nameplate.
WYT-Series (Diamante) Systems
For WYT/WT type indoor units, the serial number may be in a different location. Some batches have the serial number barcode sticker located behind the front or the electronic control box cover, for extra protection from the elements.
