(10) When the liquid leaks from the product, install it in a place where it is not subjected to
secondary damage.
(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:
VKD111AA-e, VKD131AB-e, VKD141AC-e, VKD151AD-e: M10
VKD131AF-e, VKD141AG-e, VKD151AH-e: M8
Note
Fasten the pump with bolts securely. Incomplete fixation may cause a
problem such as abnormal vibration.
(13) When lifting the pump, put ropes etc. through its lifting holes and then lift it up.
Do not lift the pump together with the equipment to which it is attached. Failure to observe this
may cause the pump to break and fall down.
(14) 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 external
dimensions drawing etc. and ensure that the total weight of the equipment
does not exceed the rated load of the hoisting device.
Warning
Do not use the pump or install any parts with the pump lifted up.
Otherwise, the unit may fall down.
Caution
When lifting up the pump, make sure the center of gravity position.
Otherwise, the unit may overturn or fall, resulting in injury and/or damage.
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.
(15) If the temperature of the liquid used is low, dew condensation may occur in the motor during a
pump stop. Take condensation prevention measures such as installing in a fully dry room or
heating and insulating the motor during a stop.
(16) 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.
(17) Do not put a cover or a filter over the motor, or it may increase the temperature inside the motor
and lead to breakage, fire, etc. of the product.
