(11) If the system could be exposed to the freezing temperature in winter, be sure to apply antifreeze
measures such as heat insulation and heater installation to the pump, valves, piping, etc.
(12) Install the pump securely.
Recommended size of pump mounting bolt: M6
Note
Securely tighten the bolts. Otherwise, it may cause abnormal vibration or
other problems.
(13) To lift the pump, install an eyenut and a hexagon head bolt at two
(diagonally-located) mounting holes of the pump, and pass a rope
etc. through the eyenuts.
Eyenut size: M6,
Bolt size: M6 x 20L (nominal length [length below the head]: 20
mm)
(14) Before installing the pump to equipment, place crossties (with a
height enough for the hexagon head bolts to be removed)
between the pump flange surface and pump mounting surface as
shown in the right figure, and remove the eyenuts and hexagon
head bolts installed for lifting. Afterwards, pull out the crossties
and install the pump.
Warning
When installing the pump, do not put your hands between the pump flange
and the pump mounting surface. Failure to observe this may cause an
injury.
(15) Do not lift the equipment with the pump attached. Failure to observe this may cause the units to
break and fall down.
(16) Use extreme care so as not to give an impact or offset load to the pump section during pump lifting
or conveyance. The pump may greatly incline depending on its center of gravity.
Warning
Before hoisting the equipment, refer to the catalogue or dimensional
outline drawing etc. and ensure that the total weight of the equipment does
not exceed the rated load of the hoisting device.
Caution
When lifting the product by hand, give attention to its center of gravity and
weight. Do not allow any product heavier than 15 kg to be lifted by a single
person. Failure to observe this may put a burden on the body, leading to an
injury.
(17) If the pumping liquid is cold, condensation may occur inside the motor while the pump is stopped.
Take condensation prevention measures such as installing in a fully dry room or heating and
insulating the motor during a stop.
(18) Carry out refinish painting with a period appropriate to a use environment. Threaded parts, worked
areas, coated parts for rust prevention and other parts may rust may depending on use
environments such as high humidity and dew condensation.
(19) Do not put a cover or a filter over the motor, or it may increase the temperature inside the motor
and lead to damage, fire, etc. of the product.
