silicone lubricant, prior to inserting into manifold.
WARNING: Do not turn the incoming water valve on until the locking
bar is in place.
NOTE: If the installation is not using the optional flush tank, the top
connection will not have tubing. Instead a plug will be inserted into the
fitting. Do not remove plug unless you are attaching the tubing and the
flush tank.
