Typical Normally Open Application

(PUMP DOWN)

  1. Attach cord, using a cable tie, to any convenient rigid surface as illustrated. This is known as the tether point. Do not tighten until both turn-on and turn-off levels are established.
    (See Fig. 1)
  2. To adjust greater distance between turn-on and turn-off, increase cord length between tether point and float. For less distance between turn-on and turn-off decrease cord
    (See Charts; Fig. 3 & 4)
  3. Make sure the float is at least 2 inches above pump base, in the turn-off position, before tightening cable tie at the tether point.
  4. Plug piggy-back switch cord (Currant Tap) into grounded outlet, then plug into piggy-back switch cord, and check for proper operation.
