Determining size of existing heat pump

[Dan]

I recently bought a house with a Lennox heat pump, about 18 years old. Model HP19-411-3P. I have the sticker from the HP unit & the installation, operation & maintenance instructions. I've also looked at all the labels/wiring diagrams on the inside of the unit's cover. Nowhere in any of this is the tonnage of the unit mentioned. I can tell you it is charged wih

11lbs 3 oz of R22. Can anyone tell me the tonnage size of this unit, or where I can find it? The Lennox site anly had the manuals I already have. Don't think it matters, but the other components are heating element unit ECB19-15-1Y & air handler CB19-41-1P.

TIA

This unit is actually a 3 ton,old Lennox model numbers don't follow the logic of using the BTU in the model number. Is this actually a three phase condenser? The 3P usually means that.

The number is marked on the 14 guage red wire on the thermostat. Your welcome.

Thanks for reminding me about the 3P Jeffery being a generation number. Lennox mixed and matched a lot of condensers and indoor coils to get different SEER ratings and BTU capacities. But the unit was designed to be a 3 ton.
