3-2
Caution
Install the product so that the total suction head (suction suction
pipe resistance) is as small as possible within the standard specifications.
Also it cannot be used if the water temperature exceeds 40
°C
, due to the
limit for self-priming capacity.
(2) If the product is used as a circulating pump, attach a sluice valve each to the suction and
discharge sides of the pump. It is not necessary to drain water out of the piping at the time of
inspection or repair of the pump.
(3) Using anchor bolts, fix the pump firmly on a level concrete foundation.
Note
Securely fix the pump in place with anchor bolts. Otherwise, it may lead to
abnormal vibration or other problems.
(4) To lift the pump, be sure to pass ropes or other lines through the underside of the common base
(or through eyebolts for the models supplied with eyebolts). Do not lift the equipment with the
pump attached.
Warning
Do not hoist the whole unit using the main shaft of the pump, the lifting
harness on the motor, or any other parts not intended for the purpose.
Warning
Before lifting the product, refer to the catalog, dimensional drawing, and
other documents to check the weight of the product. Do not lift the product
if its weight exceeds the rated load of the hoisting devices.
Warning
Never use a pump or install parts to it while the pump is lifted. Otherwise,
the unit may fall, thus leading to an injury.
Caution
When lifting the product, pay attention to its center of gravity. Otherwise,
the product may topple over or fall, thus leading to an injury.
Caution
When lifting the pump by hand pay attention to its center of gravity and
weight. Do not allow a single person to lift a product heavier than 15kg.
Failure to observe this may put a burden on the body, thus leading to an
injury.
(5) Ensure to provide a drain ditch around the pump.
Caution
Do not install the pump at an upward curve of piping (where air is trapped).
Failure to observe this may cause the pump to run dry, and seize up the
sliding part in the pump.
