Safety Precautions

RISK OF ELECTRIC SHOCK

Accidental contact with electrically live parts, items, fluid, or 

water can cause serious injury or death.

Always disconnect pump(s) from power source(s) before 

handling or making any adjustments to either the pump(s), 

the pump system, or the control panel.

All installation and maintenance of pumps, controls, 

protection devices, and general wiring shall be done by 

qualified personnel.

All electrical and safety practices shall be in accordance with 

the National Electrical Code

®

, the Occupational Safety and 

Health Administration, or applicable local codes and 

ordinances.

Do not remove cord and strain relief, and do not connect 

conduit to pump.

Pump shall be properly grounded using its supplied 

grounding conductor. Do not bypass grounding wires or 

remove ground prong from attachment plugs. Failure to 

properly ground the pump system can cause all metal 

portions of the pump and its surroundings to become 

energized.

Do not handle or unplug the pump with wet hands, when 

standing on damp surface, or in water unless wearing 

Personal Protective Equipment.

Always wear dielectric rubber boots and other applicable 

Personal Protective Equipment (PPE) when water is on the 

floor and an energized pump system must be serviced, as 

submerged electrical connections can energize the water. Do 

not enter the water if the water level is higher than the PPE 

protection or if the PPE is not watertight.

Do not lift or carry a pump or a float assembly by its power 

cord. This will damage the power cord, and could expose the 

electrically live wires inside the power cord.

The electrical power supply shall be located within the length 

limitations of the pump power cord, and for below grade 

installations it shall be at least 4 ft (1.22 m) above floor level.

Do not use this product in applications where human contact 

with the pumped fluid is common (such as swimming pools, 

fountains, marine areas, etc.).

Protect the power and control cords from the environment. 

Unprotected power and control (switch) cords can allow water 

to wick through ends into pump or switch housings, causing 

surroundings to become energized.

Single-phase 208/230V pumps shall only be operated without 

the float switch by using the circuit breaker or panel 

disconnect.

RISK OF FIRE

This product requires a separate, properly fused and 

grounded branch circuit, sized for the voltage and amperage 

requirements of the pump, as noted on the nameplate. 

Overloaded branch circuit wires will get very hot and can 

catch on fire. When used, electrical outlets shall be simplex of 

the appropriate rating.
