with a new one (P/N 20600020) if the seal is torn, cracked or brittle.

seal so that they stick out a little, just enough so that you can feel the

seal when you run a finger across the joint.

Warning! The fixture’s voltage and frequency settings must match the

local AC power source!

on the back plate. Operating at the incorrect power setting can result in poor
