CALIFORNIA PROPOSITION 65 WARNING
T
his product and related accessories contain
chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm.
GENERAL CAUTION STATEMENTS
Carefully read and follow all safety instructions in this manual
and on pumps. Keep safety labels in good condition. Replace
missing or damaged safety labels.
"Intermittent Duty" is defined as; operated and/or

frequently started within a period of time that would cause
the motor to reach its maximum thermal limits. Once the
maximum thermal limit is obtained, the motor must be
allowed to return to ambient temperature before resuming
operation.
DO NOT use to pump flammable liquids. Never operate the

pump in an explosive environment. Arcing from the motor
brushes, switch or excessive heat from an improperly
cycled motor may cause an explosion.
DO NOT assume fluid compatibility. If the fluid is

improperly matched to the pumps' elastomers, a leak may
occur. Pumps used to transfer hazardous or hot (max.
temperature 170°F [76°C] Viton® only) chemicals must be
in a vented area to guard against the possibility of injury
due to harmful or explosive liquid/vapors.
911-398 (11-01-2021)
DO NOT operate the pump at pressures which cause

the motor to exceed the ampere rating indicated on the
name plate. Various pump models are equipped with
thermal breakers to interrupt operation due to excessive
heat. Once the temperature of the motor is within proper
limits it will automatically reset, and the pump will start
operation without warning.
To prevent electrical shock, disconnect power before

initiating any work. In the case of pump failure, the motor
housing and/or the pumped fluid may carry high voltage to
components normally considered safe.
Improper adjustment of the pressure switch may cause

severe overload or premature failure. Refer to SHURflo
Service Bulletin #1031 for the adjustment procedure.
Failures due to improper adjustment of the pressure
switch will not be covered under the limited warranty.
DO NOT locate the motor near low temperature plastics or

combustible materials. The surface temperature of the
motor may exceed 250° F [120° C].
Electrical wiring should be performed by a qualified

electrician, in accordance with all local electrical codes.
All 115 VAC and 230 VAC pump motors and systems, MUST

be grounded per local and state electrical codes.
