AUTOMATIC FLOAT SWITCH
1. Install pump following installation and operating instructions.
2. Automatic float switch is sealed and factory adjusted for most home
sumps. Turn-on water level is 10" - 12" above pump base. Turn-off
water level is 4" - 6".
3. Be sure float clearance is at least 8". For best performance, the sump
diameter must be 14” and the sump depth must be 18".
4. Plug piggyback switch cord into 115V AC outlet. Then, plug pump into
piggyback switch cord.
NOTICE
: Minimum recommended turn-off level is 2" above pump
base.
Do not allow cord to interfere with float control motion or to drape over
pump motor. With electrician's tape, secure cord to discharge pipe for
cord protection.
OPERATIONAL CHECK
AUTOMATIC FLOAT SWITCH
1. Fill sump with 12"-14" of water to check operation and tightness of
connections. During first automatic cycle, it may take 30 seconds or
more before pump is primed and pumping. Turn-on will occur approx.
11" above pump base.
2. Check turn-off position. Turn-off will occur approx. 5" above pump
base.
3. If the pump does not operate, check for:
• an obstructed float switch
• a blown fuse
• proper voltage.
