7. Carefully set the Pump in place. Do not lower or raise the Pump by its Power
Cord (1) or Discharge Pipe. (See Figure E.)
8. The Float Switch (2) automatically switches on and off at a water depth of ap-
proximately 4 inches. The ON/OFF height can be manually adjusted by adjusting
the Float Switch Lock. CAUTION: Do not run the Pump dry. Doing so will
increase wear to the unit and possibly cause seal damage. (See Figure E.)
9. NOTE: This Pump has a built-in thermal protector for the Motor which automati-
cally shuts it off to avoid overheating. After the Motor cools, it will cycle back on.
Wait for the cycle to continue. Do not try to turn on the Pump manually after it
has automatically shut off.
10. Connect additional Discharge Pipe as needed to direct the water discharge to the
desired location. The discharge should be kept as short as possible with a mini-
mum number of turns. IMPORTANT: Do not exceed the maximum lift of the
Pump:
1 HP Model 93819 = 26 Feet.
1.2 HP Model 93820 = 28 Feet.
11. Connect the Power Cord & Plug (1) to its 120 volt, GFCI electrical outlet, while
making sure to form a “drip loop” in the Power Cord. (See Figure A.)
12. When the water level exceeds approximately 4 inches the Pump will
automatically turn on and run continuously until the water level falls below 4
inches at which time the Pump will automatically turn off.
13. WARNING! When shutting off power to the Pump, always shut off the
electrical power to the GFCI outlet first. Then, disconnect the Pump’s Power
Cord & Plug (1) from the GFCI outlet.
