Before starting the pump, check the oil level. Add oil if necessary. Change oil if
there are signs of degradation.
●
When placing the pump in storage, cover it to prevent foreign objects from
entering through the flange.
●
If the pump is likely to freeze in winter, remove liquid in the casing.
●
Cover the pump with a plastic sheet to prevent it from being exposed to
splashing water and dust.
●
Remove the belt and store it at room temperature, away from direct sunlight.
Avoid hanging the belt on a shelf or wall with the belt tightly bent.
●
If no countermeasures against water hammer such as a check valve have been
taken, fully close the discharge valve and then stop the pump. At this moment,
allow the internal pressure in the pump to escape with the air vent valve. (Be
aware that liquid may splatter.)
※ Stop the pump immediately after the discharge valve is fully closed.
●
If the pump is likely to freeze in winter, remove liquid in the casing.
●
Back or negative pressure must not be created in the pump djuring non-
operation. If back or negative pressure is likely to be created, fully close the
discharge and suction valves.
●
If liquid is likely to coagulate during non-operation, pass water through the
pump to clean the interior of the pump.
●
Store metal parts under favorable conditions because they are prone to rust
during storage.
