• Whenever you notice any spark while operating the product,
immediately stop its operation, and do not start using
it again unless you are sure of the cause and corrective
actions have been taken.
• Depending on the type of fluid being pumped, bubbles
of flammable gas may be generated. Make sure that
ventilation is satisfactory.
• The product itself, its fluid piping and air exhaust ports
should be kept away from unshielded fire, spark and other
causes of ignition.
• Do not operate heating devices that create flames or have
heating filaments anywhere near the pump or its piping.
• Do not leave flammable fluids inside of the product.
• Machinery and other equipment near the place of
installation of this product should be properly insulated to
prevent conduction with each other.
• Take sufficient safety precautions when operating the
product in flammable atmospheres. Flammable atmospheres
can be caused by the presence of gases, dusts or vapours.
• Lubricating compressed air with a flammable oil substance
creates an oil vapour coming out of the exhaust.
• Depending on the type of fluid being pumped and the
installation environment, static electricity could cause a fire.
• When installing the product, be sure to mount a ground
wire from the specified location on this product. When the
product is installed and operated without being properly
connected to a ground wire, friction may generate static
electricity. The ground wire must be 4.0 mm
to DOC-1 in the APPENDIX for mounting locations.
• The products should not be powered by flammable gases.
Be aware of the hazards associated with the specific
application and the application environment. Comply with
all applicable laws, regulations and codes. Do not use
the product if there is any doubt about the safety of the
application.
If you use the CSA certified model,
please consult with the dealer where you

purchased the product.
• The surface temperature of the product must be kept
below the ignition temperature of any potential explosive
atmosphere.
The surface temperature is affected by
several factors such as application, process
CAUTION
fluids or atmosphere. The end user shall
ensure that all temperatures are acceptable.
HEALTH HAZARDS
Always confirm all local laws, regulations and codes
applicable where you are operating the pump for protecting
operators from the health hazards.
• Depending on the type of fluid being pumped and the
installation environment, static electricity could cause
electric shocks.
• Hazardous fluids (acidic or alkali, flammable or toxic) or gas
bubbles generated by such fluids may cause serious injury
or even death if accidentally inhaled or consumed, or if they
come into contact with the eyes or adhere to skin.
• Always install the piping and exhaust port of this pump
away from areas where humans or animals pass through.
• If a dangerous fluid such as a(n) poison, acid, alkali,
chemical etc. comes into contact with your skin or eyes
or is ingested or aspirated, it may cause serious or fatal
injuries to yourself or others.
• Make sure you understand the characteristics of the fluid,
and that all precautions are carried out as specified by the
manufacturer of the fluid; also ensure that all workplace
safety laws and other applicable regulations are adhered to
correctly, before installing and operating the product. Make
sure the correct safety equipment such as gloves, glasses,
masks and protective clothes are used, and correct
handling procedures are followed. Always review the Safety
Data Sheet (SDS) and follow all handling instructions.
ENVIRONMENTAL HAZARDS
• When a diaphragm is damaged, fluid will gush out together
with air through the exhaust port. Also, when the pump has
a positive suction head, liquid will be forced out from the air
exhaust port due to positive inlet pressure when a diaphragm
is damaged. Also be sure you are using a model with
appropriate corrosion resistance for the fluid to be pumped.
• In case of diaphragm failure, the exhaust from the product
may contain some sludge. Make sure environmental
regulations are observed when operating the product in a
location where this may have an impact on the environment.
4. BEFORE USE
METHOD OF TRANSPORTATION
Be aware that the pump may be very heavy. When lifting, use
a hoist or crane, using the specific lift point(s). Refer to DOC-1
in the APPENDIX.
When you transport the product, release pressure from the
products and all piping, take away all hoses and piping and
drain all fluids from inside the product.
