    Jandy LX Heater start-up question

    Just a quick start-up question: The manual says to fill the copper line that connects to the pressure switch with about 5cc of SAE 50 non-detergent oil.

    1. Can I use SAE 30 non-detergent?

    2. If not, where do I get SAE 50 non-detergent?

    Thanks in advance!

    I was able to find SAE 50 at the first Auto supply store I went to. I believe it's used in heavier duty engines, so you might want to try a tractor supply or something along those lines. 30 is better than nothing, which is how many of the heaters around here with replaced pressure switches are running, but I bet you can find the full viscosity stuff nearby. If not, there's always the web.
