It is a new AC motor, into the rotor of which isembedded not coil, but a permanent magnet. It is a
new generation of motor, in which practicalapplications have progressed as a result of thedramatic improvements in the performance of
permanent magnets that have been made in recent
years. It features a small size, a light weight, highefficiency and high power. Especially, that's energy
saving performance is admired.

3 Extremely enhanced overall efficiency
Beginning with impellers, we havethoroughly reviewed the structure of thepump with fluid motion analysis raised
the overall unit efficiency up.
Improving overall efficiency is effective
for making pumps energy-saving.
KAWAMOTO PUMP aims to improveoverall efficiency in both pump efficiency
and motor efficiency.

4 Interactive control panel & self diagnosis
Each setting, condition, and error
history etc. can be checked on the
LCD display through the interactive
interface. Even in case of breakdown,
diagnostic system can detect theprobable cause, and will display it,so prompt recover is expected.

5 Super silent operation with duplex casingThis is the best choice for the building
quietness is required. Duplex casing
structure and fleshy casted casing
suppress running water sound tightly.
Electromagnetic noise from inverter isalso controlled up to the limit.

6 Easy maintenance structure
The user-friendly design makes it easy to see the structure inside the control panel, andthis in turn means maintenance has been made easier. Furthermore, the inverters can be
replaced easily from the back of the control panel.

7 Surprisingly light, but powerful
We accomplished approximately 25% reduction in Weight even though a couple ofmeters rise in Total head compared to previous model. So, conveyance became easier.

Stainless steel precision
casting
The pump casing and flanges are made fromprecision cast stainless steel to withstand heavy
load and free from strain. Stainless steel and resinmaterials are mainly adopted for portion
contacting water, thus preventing pump fromrusting and red discolorment of water. Also
conforms to leaching performance standards.

To reduce the environmental burden and protect theenvironment, we at KAWAMOTO PUMP will keep on
carrying out activities as a united force under our slogan"Comfort Earth", as a company involved with thevaluable resource that is "water".

Kawamoto products with this mark are products withexcellent energy-saving and environmentally friendly
features.

Always read this manual thoroughly and fully comprehend the contents before starting use. Precautions for using this product safely

for preventing personal injuries or physical damage are given in this manual. * We bear no responsibility when the above listed
Important safety precautions andprecautions are not observed.

●Select a product which is appropriate for your application. Inappropriate use of products may cause accidents.
●Do not use the product for applications out of the product specifications. Doing so
may cause electric shock, fire, water leakage, etc.
●When using this pump for living things (fishery, fish tank, aquarium, etc.) or importantequipment, always prepare a spare unit. If the pump fails, an oxygen deficiency ordegradation of water quality, etc., could occur and affect the creature's life.
●If used to transport food-related items, give due consideration to the materials used.
Contamination by foreign objects may occur.
●Avoid using this product with living things that are susceptible to copper alloys. The
life of the creature could be affected.
●Do not directly connect pump with water main. It maybe prohibited under the Water
Supply Law. Also, water backflow may contaminate tap water.
●Carry out installation in accordance with applicable legal requirements (electricalequipment guideline, interior wiring regulations, building codes, etc.) Failure toobserve this may not only violate legal requirements, but could also result in fire orelectric shock, or injury caused by falls or topples.
●Observe the service life of the pump, install it in a well ventilated place free fromcorrosive or explosive gases, salt, moisture, water vapor, condensation etc., andavoid exposing it to wind, rain and direct sunlight. In a harsh environment, electricleakage, electric shock or fire may result from deterioration of insulation in the motor
or control panel, etc.
●Do not install the pump in a location that has not been treated for drainage, or thathas not been waterproofed. Water leakages could result in significant damage. * Webear no responsibility for any damage arising from lack of drainage or waterproofing.

●Depending on the equipment, install the appropriate filter or etc in accordance withthe application, properly flush the system and make sure that it is free of foreign
matter before starting operation. Cutting oil, rubber mold releasing agent, foreign
objects etc. from the manufacturing line and cutting oil, foreign objects etc. from thepipeline may contaminate the liquid which is to be handled.
●Install buzzers, etc., as an alarm to alert failure to be noticed. Failing to do so may
result in serious accidents without noticing a failure.
●If using devices such as flush valve associated with sudden changes in flow rate,
consult your dealer or KAWAMOTO beforehand. Using a flush valve while the pump is
stopped will cause the pressure inside the pipes to drop suddenly, and this could
result in pressure fluctuations or mixing with air.
●Do not equip the pump with a phase advancing capacitor. Failure to observe this
could lead to trouble such as abnormal heat generation.
●When using a generator with models equipped with an inverter, contact your dealer
or KAWAMOTO. Failure to observe this could result in control panel (electric parts
assembly box) or generator faults or damage.
●Do not put the flammable items on the pump surroundings or inside the pump coveror control panel, or cover the pump, cable or control panel with the flammable items.
Failure to observe this could overheat and result in burning.
●Only repair technicians may disassemble, repair, modify the products or replace
cables. Improper repairs could result in electric shocks, fires, faults or break.
●It is recommended that both periodical and daily inspections be performed in orderto ensure that the pump will operate reliably for as long as possible. Failure to
perform inspections may lead to pump failure, accidents etc. For periodic inspections, please consult your distributer or our nearest sales offices.

Specifications/configurations may be altered as a result of improvements and such. Unauthorized reproduction of this document is prohibited.
