pump, follow electrical safety instructions. only trained
service personnel should install or service this pump.
1. do not splice the power cord and never lay the
cable ends in water.
2. do not handle or service the pump while it is
connected to the power supply.
3. do not operate the pump unless it is properly
grounded. Wire the pump directly into a grounded
terminal block in an automatic float or pump
controller box for automatic operation. Connect
the pump according to all applicable codes. For
continuous operation, wire the pump directly into
the switch box.
4. Incorrect voltage can cause a fire or seriously
damage the motor and voids the warranty. Make
sure that the frequency and voltage shown on the
nameplate corresponds to the frequency and voltage
of the electrical supply. the supply voltage must be
10% of the nameplate voltage. If in doubt
consult a licensed electrician.
5. Connect the pump to its own dedicated circuit with
no other load on the circuit. Figures 3, 4 & 5 show
single and three phase wiring schemes.
