Sa fety Guidelines
Sa fety Preca utions

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.

Accidental contact with electrically live parts, items, fluid, or
water can cause serious injury or death.

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 200/230V pumps shall only be operated without
the float switch by using the circuit breaker or panel
disconnect.

Do not use an extension cord to power the product. Extension
cords can overload both the product and extension cord
supply wires. Overloaded wires will get very hot and can catch
on fire.
