2. Before operation
Confirm pump performance and specifications prior to operation.
1.
Do not run the pump in closed-discharge operation. Always keep the rated minimum flow of 10L/min.
Also, do not send any medium other than fluid.
2. Prime the pump before self-priming operation
The SMX-F is a self-priming pump, however, the pump needs to be primed to a certain liquid level before
operation. Once the pump is primed, generally the pump doesn't need to be primed at each operation
because the pump keeps a needed liquid level for the next self-priming. But then the pump still needs to
be primed after a long period of storage (one day or more) or when the self-priming operation was not
completed (when the pump stops running before liquid was discharged.).

NOTE: Do not pour liquid rapidly. Otherwise liquid may overflow.

●
Do not remodel the pump
A remodelled pump will not be warranted. Also, we are not responsible for a
personal injury or property damage due to any modification.
●
Be sure to prime the pump before operation
Always prime the pump when the pump is empty, for example, the pump is
used for the first time or after dismantlement/assembly. Running the pump
without priming water, internal parts are excessively worn by friction heat and
fatal pump damage results.
●
Do not run pump dry
Do not run pump dry (Operation without priming water or with a suction valve
closed). Otherwise, internal parts are excessively worn by friction heat and
fatal pump damage results.
* If the pump runs dry by mistake, turn off power and leave it for more than
one hour to cool it down. Quick cooling can give rise to cracks on parts.
* An Iwaki dry run protector, the DR model, is recommended for the preven-
tion of dry running.
●
Do not bring the pump close to a flammable substance
Keep the pump away from a flammable substance for the prevention of fire.
