6. Disconnect all power sources before servicing Failure to do so could result in serious injury or death FLOAT CONTROLS Check the floats through their entire range of operation Clean adjust or replace damaged floats Checking the float resistance The float resistance can be measured to determine if the float is operating cor rectly or is defective Use the following procedure to measure the float resistance 1 Isolate the float by disconnecting one or both of the float leads from the float terminals 2 Place one ohmmeter lead on one of the float wires and the other ohmmeter lead on the other float wire 3 Place the ohmmeter dial to read ohms and place on the R X 1 scale With the float in the off position the scale should read infinity high resistance Replace the float if you do not get this reading With the float in the ON position the scale should read nearly zero very low resistance Replace the float if you do not get this reading NOTE Readings may vary depending on the length of wire and accuracy of the measuring device FUSES Check the continuity of the fuse Pull the fuse out of the fuse block With the ohmmeter on the R X 1 scale mea sure resistance A reading of infinity indicates a blown fuse and must be replaced Replace fuse with same type voltage and amp rating TRANSFORMER The 331 panel can be configured to operate at 208VAC 230VAC or 460VAC It is factory set for 460VAC opera tion Check the
