Hayward auto chlorinator, cal hypo pucks

[Alex36]

trying to find info if cal hypo pucks can be used in a hayward auto chlorinator which is new?

You cannot use cal-hypo in a device designed for trichlor. It is also unsafe to use cal-hypo in any container that has previously contained trichlor due to the potential reaction it could have with any trichlor residue.
(I know you said it is new, but that's an important point for anybody reading this thread in the future)

A tricolor puck feeder is not designed for cal hypo use.
