Tecumseh Compressor Q&A
What oil is used in an R-12 compressor manufactured today?
What is synthetic alkylate oil?
Synthetic alkylate is another name for alkylbenzene, which is used in many of Tecumseh's hermetic compressors.
Is 3GS mineral oil compatible with "white oil" and alkylbenzene oil?
Yes. They have different properties, but they are chemically compatible.
How long may I leave a compressor charged with POE oil open to the atmosphere?
No more than 15 minutes maximum.
Can blends be charged as vapor?
No. Blends must be charged in liquid phase.
Can R-410A be used in a compressor designed for R-22?
No. Tecumseh is currently developing a line of R-410A compressors.
What is the highest acceptable motor winding temperature for your hermetic motors?
265 degrees Fahrenheit, measured by the resistance method, is the highest acceptable temperature for Tecumseh's hermetic motors.
At what speed do your hermetic compressors run?
Tecumseh's 60 Hz. compressors run at a nominal 3450 rpms at rated voltage, and their 50 Hz. compressors run at 2,875 rpms.
Can I use a "one size fits all" type of start relay on all of Tecumseh's hermetic air conditioning compressors?
No. Tecumseh Engineering department has selected specific relays for each compressor to meet their starting specifications.
I don't have the correct voltage rating on a run capacitor, as specified in the Tecumseh literature; can I use a different voltage rating?
• Yes. The voltage rating of all capacitors must be the same as, or greater than, the specified voltage.
If I am replacing a failed compressor with a like new compressor can I use the electrical components from the old compressor on the new compressor?
You should use only new electrical components (e.g. relay, start capacitor, run capacitor) designed for use with the new compressor.
Is it safe to use leak detection dyes in air conditioning and refrigeration systems?
Tecumseh does not endorse the use of any substance in the system except the oil and refrigerant designed for use in the specific compressor.
Do Tecumseh's capacitors contain PCB oil?
Since January 1979, capacitors provided by Tecumseh have contained non-PCB oils.
Do Tecumseh compressors contain PCB's?
Does Tecumseh have a mathematical equation and coefficients for your compressors' performance data?
Yes. Tecumseh publishes compressor performance information in the ARI Standard 540 format.
In air conditioning applications, how does horsepower compare to Bth/hr?
At air conditioning rating conditions one horsepower equals 12,000 Btu/hr.
Can I use my own grommets on Tecumseh's compressors?
Yes, if they pass your system shipping/transportation and sound/vibration tests.
What is "D21"?
Discharge temperature measured with an insulated T/C two inches from the compressor tube to line joint.
Why can't I move the electrical warning label or bar code labels?
Readers or scanners in production are fixed and changing would have to be agreed upon by all customers. Safety reasons govern changing the electrical label.
