our model is the bI36R/s and the bI36F/S We had on order for 8 months the monogram all freezer and fridge but changed when they came out with announcement. We ordered these about 6 weeks ago fully expecting them to come in October. To our surprise they came in early. We are in California and bought them thru Pacific Sales. I love the looks of them! :)

Update due to new information. If your serial number on your refrigerator is between 4116297 and 4134313, please call SubZero at (800) 222-7820. 1st generation of these refrigerators utilized a push mechanism to attach the filter. This is being phased out and new units are like I mentioned above. Yours will need to be converted and SubZero will do this at no charge but you need to coordinate through them, not just any service place.

Antss - I think you're mistaken, and it's your posting that's likely to confuse people. As I wrote earlier, the rough opening specification for BI-36U is 35-1/2 wide by 83-3/4" tall. That is exactly the same as the rough opening for the previous 650 model. If you're replacing a model 650 (or a 550, for that matter) wirh a new BI-36U/S Classic Stainless model, a framed panel model, or an overlay model, it will slide right into the same space that the old model was in. No alteration is necessary. Only the new Flush Inset models require slightly different clearances to allow the larger door fronts to swing unimpeded and to match up with the cabinet door fronts on surrounding cabinetry. If you're installing a new Flush Inset model, the rough opening is still 35-1/2" (between the mounting cleats) by 83-3/4". The difference is the way that allowance needs to be made for the refrigerator door panels, which are 37" wide, and thus wider than the appliance case. The door panels on a flush inset model requires 38" of space in front of the side mounting cleats and between the doors or drawer fronts on either side of the refrigerator. See the diagrams in the Sub-Zero instruction manual. The rough opening in the cabinet carcass (or between the cleats), however, remains unchanged from the rough opening specification on earlier models -- 35-1/2" x 83-3/4" with a minimum of 24" depth to the front of the mounting cleats on either side of the appliance. See pages 8 & 9 of the Sub Zero Installation Instructions at the link below. It's all clearly illustrated. Crazykitchen54 - If you're going with the Classic Stainless Steel model, the installation specification for the rough opening dimensions are exactly the same as the specification for older models.

chaos, don't worry about it - you'll love your new fridge and you can use your savings on some other splurge. We finally got our 632S installed and the water filter was so easy to install - we got one that uses copper tubing vice plastic - the fittings are right in the front and we can change it in about 2 minutes. The whole unit is on wheels and slides out very easily anyway if you need to get to the back for anything. What do you need an air filter for anyway? Is that to replace a box of baking soda?
