ASSEMBLY INSTRUCTIONS
Carefully turn the sink right-side up, 
standing on the legs.
Unscrew the large 3-3/8” Nut from the 
bottom of the DRAIN (D) assembly. 
Insert DRAIN (D) through the opening at 
the bottom of the SINK (A) from the 
inside. From under the SINK (A) first 
slide the Rubber Washer on, then the 
Paper Gasket, and finally, tightly screw 
the large 3-3/8” Nut back on. A pipe 
wrench could be used to tighten if 
necessary.
Lay the SINK (A) upside-down and insert 
LEG (B) into the round collars on the 
bottom of the SINK (A). 
Use the HEX KEY (F) to tighten the HEX 
SCREW (E) into the SINK (A). Turn the 
HEX KEY (F) as far clockwise as 
possible. Take out the HEX KEY (F), 
reposition, reinsert, and turn as far 
clockwise as possible, repeating as 
necessary until the HEX SCREW (E) is 
securely in place.
Repeat for each LEG (B).
