Please Read This Before Installing Or Operating
Pump. This information is provided for SAFETY and
to PREVENT EQUIPMENT PROBLEMS. To help
recognize this information, observe the following
symbols:
IMPORTANT! Warns about hazards that can
result in personal injury or Indicates factors
concerned with assembly, installation,
operation, or maintenance which could result
in damage to the machine or equipment if
ignored.
CAUTION! Warns about hazards that can or will
cause minor personal injury or property damage if
ignored. Used with symbols below.
WARNING! Warns about hazards that can or
will cause serious personal injury, death, or major
property damage if ignored. Used with symbols
below.
Only qualied personnel should install, operate and
repair pump. Any wiring of pumps should be performed
by a qualied electrician.
WARNING ! To reduce risk of electrical
shock, pumps and control panels must
be properly grounded in accordance with
the National Electric Code (NEC) or the
Canadian Electrical Code (CEC) and all
applicable state, province, local codes
and ordinances. Improper grounding voids
warranty. Prior to energizing the pump, a
verication of the pump ground circuit should
be made between the pump case and panel
ground.
WARNING! To reduce risk of electrical
shock, always disconnect the pump from the power
source before handling or
servicing. Lock out power and tag.
WARNING! Operation against
a closed discharge valve will cause premature
bearing and seal failure on any pump, and on
end suction and self priming pump the heat build
may cause the generation of steam with resulting
dangerous pressures. It is recommended that a high
case temperature switch or pressure relief valve be
installed on the pump body.
CAUTION ! Never operate a pump with a
plug-in type power cord without a ground
fault circuit interrupter.
CAUTION ! Pumps build up heat
and pressure during operation-
allow time for pumps to cool
before handling or servicing.
WARNING ! Do not pump hazardous
materials (ammable, caustic, etc.) unless
the pump is specically designed and
designated to handle them.
CAUTION ! Do not block or restrict
discharge hose, as discharge hose may
whip under pressure.
WARNING ! Do not wear loose clothing
that may become entangled in moving
parts.
WARNING ! Keep clear of suction and
discharge openings. DO NOT insert ngers
in pump with power connected.
Always wear eye protection when working
on pumps.
Make sure lifting handles are securely
fastened each time before lifting. DO NOT
operate pump without safety devices in
place. Always replace safety devices that
have been removed during service or repair.
Secure the pump in its operating position so
it can not tip over, fall or slide.
DO NOT exceed manufacturers
recommendation for maximum
performance, as this could cause the motor
to overheat.
DO NOT remove cord and strain relief.
DO NOT connect conduit to pump.
WARNING ! Cable should be protected at all
times to avoid punctures, cut, bruises and
abrasions. Inspect frequently. Never handle
connected power cords with wet hands.
WARNING ! To reduce risk of electrical
shock, all wiring and junction connections
should be made per the NEC or CEC
and applicable state or province and local
codes. Requirements may vary depending
on usage and location.
WARNING! Submersible Pumps are not
approved for use in swimming pools,
recreational water installations decorative
fountains or any installation where human
contact with the pumped uid is common.
WARNING! Products returned must be
cleaned, sanitized, or decontaminated
as necessary prior to shipment, to insure
that employees will not be exposed to
health hazards in handling said material.
All Applicable Laws And Regulations Shall
Apply.
Bronze/brass and bronze/brass tted
pumps may contain lead levels higher than
considered safe for potable water systems.
Lead is known to cause cancer and birth
defects or other reproductive harm. Various
government agencies have determined that
leaded copper alloys should not be used in
potable water applications. For non-leaded
copper alloy materials of construction,
please contact factory.
