Types of Symbols

Indicates that "Warning" or "Caution" must be exercised. Inside

this triangle, a concrete and practical image provided as a warning

or caution message is depicted.

Indicates a prohibited action or procedure. Inside or near this cir-

cle, a concrete and practical image of the activity to be avoided is

depicted.

Indicates an important action or procedure which must be per-

formed or carried out without fail. Failure to follow the instructions

herein can lead to malfunction or damage to the pump.

For the Safe and Correct Handling of the Pump

• Read the "Safety Instructions" sections carefully to prevent accidents involving your

customers or other person and to avoid damage or loss of other assets. Always follow

the instructions and advice found in these sections.

• Observe and abide by the instructions described in this manual. These instructions are

very important for protecting pump users from dangerous conditions and situations

related with the use of the pump system.

• The symbols relate to the following meanings described below.

Warning

Caution

Important Instruction

Nonobservance or misapplication of the contents of

the "Warning" section could lead to a serious acci-

dent, including death or injury.

Nonobservance or misapplication of the contents of

the "Caution" section could lead to serious physical

injury to the user or serious damage to the product.

Safety Section

Warning

•Wear protectors

If you touch or come in contact with any type of hazardous chemical liquid, including

but not limited to chemicals, you may experience a serious injury. Wear protective

gear (protective mask, gloves, etc.) during the pump operation.

Wear protective

gear

•Turn off the power supply

Working without disconnecting the power supply cause an electrical shock. Before

engaging upon any working procedures involving the pump, make sure to turn the

power supply switch off and to stop the pump and other related devices.

Electrical Shock

•Terminate operation

When you detect or become aware of a dangerous sign or abnormal condition dur-

ing operation, terminate the operation immediately and start from the beginning

again.

•For specified application only

The use of a pump in any application other than those clearly specified may result in

injury or damage to the pump. Use the pump strictly in accordance with the pump

specifications and application range.

Prohibited

•No remodeling

Never remodel a pump. Otherwise, a serious accident may result. Iwaki will not be

responsible for any accident or damage of any kind which is caused by the user

remodeling the pump without first obtaining permission or instructions from lwaki.

No remodeling

•Operating site must be free of water and humidity

The pump is not designed to be water-proof or dust-proof. The use of the pump in

places where water splashes or humidity is high may result in an electrical shock or

short circuit.

Prohibited

Safety Section

Caution

•Spill-out accident

Protective measures should be taken against any accidental spill-out or leakage of

the operating liquid as a result of unexpected damage on the pump or the related

piping.

Caution

•Qualified operators only

The pump operator and pump operation supervisor must not allow any operators

who have little or no knowledge of the pump to run and operate the pump. Pump

operators must have a sound knowledge of the pump and its operation.

Prohibited

•Specified power only

Do not operate the pump on voltage which is not specified on the nameplate.

Failure to do so may result in damage or fire. Only the specified power level is to be

applied.

Prohibited

•Do not run the pump dry

Do not run the pump dry (without liquid inside the pump). Heat generated as a

result of abrasion between elements inside the pump during operation without liquid

may damage the inside of the pump.

Prohibited

•Do not wet or dampen

If an electric part or wiring gets wet with the liquid spilled over accidentally, a fire or

electrical shock may be caused. Install the system in a place free from liquid

spillage or leakage.

Do not wet or

dampen

•Do not damage or change power cable

Do not scratch, damage, process, or pull the power cable forcibly. An extra load

onto the cable, such as heating the cable or placing something heavy on the cable,

may damage the cable and finally cause a fire or an electrical shock.

Caution

•Ventilate

Poisoning may result during an operation which involves, toxic or odorous liquid.

Ventilate the operating site sufficiently.

Caution

•Damaged pump

Never operate a damaged pump. A damaged pump may cause leakage or electri-

cal shock.

Prohibited

Safety Section

Caution

•Arrange grounding

Do not operate the pump without connecting the grounding wire. Otherwise, an

electrical shock may result. Make sure the grounding wire is connected with

grounding terminal.

Grounding

•Install an earth leakage breaker

The operation of a pump without using an earth leakage breaker may cause an

electrical shock. Please install a leakage breaker in the system.

Electrical Shock

•Handling of power cable

Use of a defective or damaged power cable may result in a fire or electrical shock.

Handle the power cable carefully.

Electrical Shock

•Follow the instruction manual

Replace the consumable part by following the descriptions in the instruction manual.

Do not disassemble any part of the pump if the disassembling procedure for the part

in question is not included in the instruction manual.

•Disposal of used pump

Disposal of used or damaged pumps must be done in accordance with the relevant

local law and regulations. (Consult a licensed industrial waste products disposing

company.)

•Limited operating site and storage

Do not install or store the pump in the following places :

Places where a flammable gas or material is used or stored.

Places where the ambient temperature is extremely high (40 °C or higher) or

extremely low (0 °C or lower).

1. Unpacking

After unpacking the goods, check the following

points to ascertain that the product is exactly as

you ordered.

If you find anything wrong, please get in touch with

your dealer.

(1) Do the model, voltage, etc., shown on the name-

plate represent what you ordered?

(2) Has the goods been damaged in transit? Are

the bolts and nuts loose?

2. Operation Principle

The EH Series electronic metering pump consists

of a pump unit, a drive unit, and a control unit.

The drive unit is an electromagnetic solenoid.

When the solenoid coil is energized by the control

unit the armature shaft moves forward due to the

magnetic force of the solenoid. The shaft is

attached to a PTFE faced diaphragm which is part

of the pump unit. The diaphragm is forced into the

pump head cavity decreasing volume and increas-

ing pressure which forces liquid in the pump head

out though the discharge check valves. When the

solenoid coil is de-energized, a spring returns the

armature to its starting position. This action pulls

the diaphragm out of the head cavity increasing

volume and decreasing pressure. Atmospheric

pressure then pushes liquid from the supply tank

through the suction check valves to refill the pump

head.

specified on the control unit. (Check the nameplate.)

Caution

Operation with a pump having different symbols for driving unit and power source voltage other than

those specified may cause failure or trouble in the electronic circuit of the control unit or the driving

unit of the pump.
