Want to find some information on your unit? In the search box below, enter a unit serial number and find it! Please note that lookup by Sales Order and Purchase Order currently only applies to products produced 2014 and earlier. Serial Number Sales Order Purchase Order. An earlier serial number system, that was used until October 2004, has a sequence of four letters followed by a string of six numbers.

You can determine the “nominal” size of your HVAC system by examining the model number on the data plate at the side of the condenser (outdoor unit). Myanmar 3 font free download for mac. Just like the nominal size of lumber or an air conditioning filter, the exact cooling capacity may be a little more or less than the nominal rating, but it’s close.For York, you should look for first two numbers in the model number. They are divisible by 6 or 12, which represent the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 48 divided by 12 equals 4, so the data plate below indicates the system is 4 tons.Here’s a rundown of the range you will encounter: 18 = 1.5 tons, 24 = 2 tons, 30 - 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, 48 = 4 tons, and 60 = 5 tons. And this is another one that is 2 tons.If you are unsure whether you have found the right two numbers, you can double-check it by looking for the “RLA” rating on the data plate.

Create a new node subclass with your algorithm. DistortX will follow soon.Also, there's a new sample folder with some examples of how to use them.You can even replace the screen by your own expression. Release 0.8.1 is out, with bug fixes, fixes in the linux package and some new features.There are 3 new nodes: GenerateX, ColorX and LayerX, that useto generate / color correct and composite images. Use the inspector and the image viewer for testing and instant feedback.If you are not convinced yet, take a look at theThere is a fine review of Ramen at. Just copy the file ui/splash.sein the package, edit it and copy it to $HOME/ramen1.0/ui.Check SeExpr's site for more info.I bundled Python 2.7 in this release, but there's not much you can do with it yet.For now it's more of an experiment to lean how to distribute python with an application.And finally, I added a Move3D node.

RLA is an acronym for Rated Load Amperage, and is what the maximum amperage should be when the condenser up and running. If you divide the RLA by 6 for older units and 5 or 6 for newer units, you should get a number that approximates (not exactly) the tonnage of the system.

Make sure you use RLA and not LRA, Locked Rotor Amperage, which is the surge of amps necessary to overcome inertia and start the system. It averages around five times the RLA.To determine the date of manufacture of a York system, see our blog post.To learn more about heating and air conditioning systems, see these other blog posts:.Visit our page for other related blog posts on this subject, or go to the for a complete listing of all our articles.
