Countertop Icemaker IMD Series Installation Manual WATER LEVEL CONTROL HOW WATER LEVEL CONTROL WORKS When water is introduced through the inlet fitting the float rises. The float pushes against a lever which in turn forces the poppet assembly against the inlet fitting valve seat which seals the water off, (see FIG- URE 4). Before the water inlet is sealed the safety switch is operated. In the event of a water failure the float would drop down and operate the safety switch to shut off the ma
