switch in Remote 14 position, and be sure remote control is connected to Remote 14 receptacle (see Sec-
tions 4-7 and 3-4).
Be sure Power switch is On (see Section 4-11).
If remote control is not used, place Amperage switch in Panel position. If remote control is used, place
switch in Remote 14 position, and be sure remote control is connected to Remote 14 receptacle (see Sec-
tions 4-7 and 3-4).
Be sure Peak Amperage control is set above the minimum (0) (see Section 4-3).
