SAFETY INFORMATION
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS: For optimal performance and
operation, read these instructions carefully before installing
your new pump. This manual provides valuable guidance and
instructions that should be followed to perform installation,
operation and maintenance procedures for this product. It should
be kept near the installation for immediate reference. Record
nameplate data from your new pump on the blank template
located in “Maintenance” on Page 7 for future reference.
This is the safety alert symbol. When you see this symbol on
your pump or in this manual, look for one of the following signal
words and be alert to the potential for personal injury.
warns about hazards that will cause serious personal
injury, death or major property damage if ignored.
warns about hazards that can cause serious personal
injury, death or major property damage if ignored.
warns about hazards that will or can cause minor
personal injury or property damage if ignored.
NOTICE indicates special instructions which are important but
not related to hazards.
The hazards stated in this manual are not all-inclusive. To
minimize the risk of hazard, it is strongly recommended that
installation, operation and maintenance be performed by a
qualified professional in accordance with local codes and
standards for safe operation.
CALIFORNIA PROPOSITION 65 WARNING
This product and related accessories contain
chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm.
ELECTRICAL SAFETY
Risk of electric shock. Can shock, burn or kill. All
wiring should be done by a qualified electrician.
Wire motor for correct voltage. See “Installation” section
(refer to page 5) of this manual and motor nameplate.
Ground motor before connecting to power supply.
Follow wiring instructions in this manual when connecting
motor to power lines.
A complete power disconnect switch must be incorporated
in the fixed wiring.
Install, ground, wire and maintain your pump in compliance
with all applicable national and local codes and ordinances.
Consult your local building inspector for code information.
GENERAL SAFETY
Risk of explosion. The pump body may explode if
used to boost pressure above the pressures noted on Page
3. Do not use this pump with inlet pressure greater than
70 psi (483 kPa) or less than 3 psi (20.7 kPa). If not already
in the piping system, install a pressure relief valve in the
pump discharge line capable of passing the full pump flow at
maximum rated pressure. If local code requires installation
of a pressure relief valve capable of handling the full pump
flow at a pressure less than 100 psi (689 kPa), follow the code
requirements.
Risk of fire or explosion. To avoid risk of fire and
explosion, pump water only with this pump. Do not pump
salt water, flammable liquids or chemicals. Do not use the
pump near gas pilot lights or where chemical or gas fumes
are present.Use of an electric pump with liquids other than
water or in an atmosphere containing chemical or gas fumes
may ignite those liquids or gases and cause injur y or death
due to an explosion and/or fire. Pump approved liquids only
with this pump.
Risk of burns. If water is trapped in the pump
during operation it may turn to steam. Trapped steam may
cause an explosion resulting in injur y or property damage.
Never run the pump with the outlet closed or obstructed.
Risk of freezing. Do not allow pump, piping, or
any other system component containing water to freeze.
Freezing may damage system, leading to injury or flooding.
Allowing pump or system components to freeze will void the
warranty.
NOTICE only service agent or qualified person should
replace power cord to avoid injury.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on pumps.
Keep work area clean, uncluttered and properly lighted;
store properly all unused tools and equipment.
WARNING
Risk of explosion and scalding. Never run
pump against closed discharge. To do so can boil water
inside pump, causing hazardous pressure buildup and
possible explosion.
CAUTION
Risk of flooding. Do not run the pump dry. This
will damage mechanical seal and void warranty. It may cause
burns to person handling pump.
CAUTION
Motor normally operates at high temperature
and will be too hot to touch. It is protected from heat
damage during operation by an automatic internal cutoff
switch. Before handling pump or motor, stop motor and allow
it to cool for 20 minutes.
