How do I assemble the DYF012 Series fan?

First, gently turn the fan upside down and place the power cord through the recessed channel in the center of the rear base assembly. Align the rear and front base assembly and snap them together by pushing the 4 round extrusions into the adjacent circles. Then use 3 (M5 x 12) screws with a Phillips head screwdriver to secure the base to the bottom of the fan housing, and place the power cord in the holding bracket. Finally, turn the fan right side up and it will be ready for use.
