are you talking about the "tank in tank" water holder/collector ? If so remove the three screws at the bottom of the unit , where the water would come out and go into the machine. place the bladder, where you would put the clean water, in side the tank making sure the bladder opening goes through the opening at the bottom where you removed the 3 screws, so that the lip is on the outside. place the nipple piece back in place and insert screws and tighten.
