This symbol indicates safety instructions where non-compliance
would affect personal safety and could result in serious injury.
This symbol indicates safety instructions where non-
compliance will involve some risk to safe operation and personal
safety and would damage the equipment and or property.
Do NOT pump
Gasoline or flammable fluids with flash
point below 98°F (37°C) Explosion or serious injury may occur.
Incompatible fluids may cause premature failure of the
pump. It is the customer’s responsibility to ensure that
fluids are compatible with pump materials.
If used with
C02 or N2
be sure the area is well
ventilated.
If pump is to be used in high flow, low pressure
applications, adjust air pressure to 20 PSI (1.38 bar) above
discharge pressure.
Do NOT
Exceed 100 PSI (6.9 bar) Air Inlet
Pressure.
Continuous operation above 120
°
F (48.9
°
C)
will reduce pump life.
Inlet air must be dry and oil free - use an air/oil
filter and air dryer.
Mount with ports facing down.
To Reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of equipment.

PREVENTIVE MAINTENANCE TIPS
Tips to help prolong your pump’s life.
• If pumping liquid other than water, pump should be
flushed with water (if applicable) after every use.
• Before freezing conditions occur, pump must be liquid free.
• If mounting pump in an outdoor environment, shield
pump from environmental extremes (i.e. sunlight, water
from washdown spray, rain, etc.). Avoid high heat and
humid installations.
• When using an air compressor, use an inline air dryer
(PN# FJ520B) before the pump to limit water build-up.
