question about janty kissbox

[jennyhadadot]

Hi, this is a dumb question, I know, but I am a NOOB at all this. I have the Janty kissbox which I love using with the manual switch. Problem is the parts are very expensive compared to other units. My question is: what model is the kissbox exactly??? is it an 801 or 901?? I know I can find parts cheaper overseas, but I don't know what to look for? Any help will really be appreciated!!! thanks
