For suction operation
•
Close the sluice valve on the discharge side of the pump.
•
Remove the priming plug, and pour water.
(In the case of ASVM(N)(G) 25 and 32, also loosen the bypass plug.)
• Rotate the pump by hand to completely expel air from the inside.
•
After checking that the suction pipe and the pump are sufficiently filled with water, attach the
priming plug.
•
After starting the pump, gradually loosen the air vent plug needle to check that water comes from
the air vent plug.
* When starting the pump, be sure to refer to "4.2 Pump operation (test run)."
•
After air release, tighten the air vent plug needle.
(In the case of ASVM(N)(G) 25 and 32, also tighten the bypass plug.)

Pump operation (test run)
Danger
After turning on the main power supply, do not touch the current-carrying
parts.
Because a high voltage is applied to the current-carrying parts, a
significant danger may be posed if you may receive an electric shock.
Warning
Be sure to install the cover of the terminal box of the electric motor.
Otherwise, you may receive an electric shock.
Warning
Before operating the pump, be sure to attach the coupling guard.
Otherwise, you may get entangled and injured.
Warning
Do not put your fingers or other objects into the opening of the motor.
An electric shock or injury may occur.
Note
The drain plug of ASVM(N)(G) 25 and 32
has a double structure.
• For priming, loosen the bypass plug
only.
After the completion of priming, be sure
to retighten the screw.
• When discharging water, remove the
main body of the drain plug.
•
Caution
Do not excessively loosen the bypass
plug. Otherwise, the internal parts may
be damaged, and the performance may
be reduced.
