Risk of electric shock – cord connected models are supplied with a grounding
conductor and grounding-type attachment plug. To reduce risk of electric shock, be
certain that it is connected only to a properly grounded, grounding-type receptacle.
Three power cord plug types available.
Power cord length is 6 feet (3.83 meters)
WARNING
Be certain to connect pump to proper supply voltage. Using incorrect voltage will damage pump and may result in
injury. Voltage requirement is printed on pump serial label.
Input power: 115VAC 50/60 Hz 1.5 amp or 230/240VAC 50/60 Hz 0.7 amp.
Power switch located in Junction Box.
Use voltage your power cord is rated for.
Cord connected models are supplied with a ground wire conductor and a grounding type attachment plug (power
cord). To reduce risk of electric shock, be certain that power cord is connected only to a properly grounded,
grounding type receptacle.
Permanently connected models must be properly grounded. Be certain that a grounding conductor is connected
to terminal T11-1 located in wiring compartment.
Never strap control (input / output) cables and power cables together.
Power Interruption:
This pump has an auto-restart feature which will restore pump to operating state it was in
when power was lost.
Note:
When in doubt regarding your electrical installation, contact a licensed electrician.
Electrical connections and grounding (earthing) must conform to local wiring codes. Be
certain that a grounding conductor is connected to terminal T11-1 located in wiring
compartment.
