Remove the white cap from the end of the spray hose. Hook the spray hose to the body of the faucet by pushing the hose into position and then using the white clip to hold it in place.
Attach the weight onto the spray hose. The weight needs to be positioned near the white tape on the prayer hose. To work properly the weight needs to move up and down freely with the spray hose. Test it by pulling spray wand out and putting it back into the faucet spout. The spray hose should move without hitting anything under the sink.
