I went to the customer's home to install a condensate pump and add a PVC to 1 1/2" drain trap. I put a rubber boot on the drain pipe to extend higher and turned the power off to the unit. I then removed the door and wired put for power. I then ran drain line to pump and connected the drain tube. I turned the power back on and tested with the customer. There are no leaks and the unit is in working order.
