1) Purchase and install a fan rated electrical box if you aren’t replacing an old fan. I did this cause I was replacing a light fixture with this fan. 2) Assemble everything except the mounting flange and light cap before climbing a ladder. 3) Screw in the mounting flange ground wire to the fan box before placing the downrod rod onto the flange.
