Before Using the Equipment

Thank you for purchasing this product. Your custom is very much appreciated.

This pump is designed solely for vacuum discharge, and may malfunction or cause accidents if

not handled appropriately. Read the manual thoroughly, and pay due attention to inspections,

maintenance, and safety.

Personnel Handling the Equipment

Only persons who have read this manual thoroughly, and have sufficient understanding of

safety, pump specifications, and method of operation, may operate this pump.

Read the Manual Thoroughly

Read the manual thoroughly in order to use the equipment correctly. Read the section on

Safe Use particularly closely.

Keep This Manual in a Safe Place

After reading this manual, be sure to keep it in a safe place, which is readily accessible to

others needing to use it.

Copying This Manual Is Prohibited

No part of this manual may be copied for use by a third party without the express

permission of the manufacturer.

Statutory Requirements for Disposal

Follow all statutory and local authority regulations when disposing of this pump.

Safety During Repair

Please provide a full description of the circumstances of use (particularly the use of

dangerous materials) for the safety of repair personnel when requesting the manufacturer

for repairs to the pump. Your request for repair of may be refused if these circumstances

are unclear.

Checks When Opening Packaging

Check the following after opening the packaging.

(1) Is the product as you requested?

(2) Are the accessories and necessary parts included?

Standard accessories

・User’s manual -------------------- ×1

・Inlet and outlet caps (fitted to inlet and outlet) -------------------- ×2 (DAT-50DA)

-------------------- ×3 (DAT-100SA)

(3) Is the pump damaged in any way?

(4) Are any external screws or inlet and outlet pipes loose? Are any components missing?

Contact your agent or the sales division of the manufacturer if there are any problems with the pump.

1. Ensure that the tube on the side of the pump is not gripped or bent when removing

the pump from the packaging. Holding the pump by this tube may damage it, thus

reducing pump performance.

2. Always remove the vent plug before using the pump.

3. Fit an inlet filter if there is a possibility of foreign matter or dust particles entering the

pump.

4. Use ventilation holes, and fit a cooling fan, to reduce the temperature in the vicinity of

the pump. Ensure that a space of at least 100mm is available on all sides of the

pump.

Using the Pump Safety

To ensure that the pump is handled correctly, read this section thoroughly before use.

This manual and the warning labels on the pump include safety icons as an aid to understanding safety

requirements.These safety icons warn the operator and others of possible dangers and damage and

should always be followed.

・Safety symbols

The meanings of the safety symbols are as follows.

Incorrect handling of the equipment is very likely to result in death or serious injury to the

operator.

Incorrect handling of the equipment may result in death or serious injury to the operator.

Incorrect handling of the equipment may result in light or medium injuries to the operator or

damage to the equipment.

Incorrect handling of the equipment may result in damage to the equipment and hinder its

correct operation.

Some components reach surface temperatures in excess of 60ºC during pump operation.

Burns may result if these components are touched during operation.

To prevent electric shock, always shut-off the primary power supply before working on

electrical wiring, or engaging in any electrical work.

Cautions for Safety in Use

Applications

(1) This pump is not designed to be explosion-proof, and should therefore not be used to

discharge explosive gases.

(2) In addition to discharge of gas via the outlet, gas may also leak from other parts of the pump,

and it should therefore not be used with toxic gases. If toxic gas is discharged for any reason

it is important to note that the interior of the pump will be contaminated by the gas, requiring

appropriate caution during maintenance.

Maintenance and Repair

(3) When requesting the manufacturer’s service division to dismantle and repair the pump,

always note the gas which the pump has been used with on the Usage Status Check Sheet.

Note that if it has been used to discharge toxic gas for any reason it will be contaminated.

Please be aware that use with some gases will preclude dismantling and repair.

Installation

(1) Do not use the pump in an explosive atmosphere. Such use may result in injury and fire.

(2) Ensure that there are no inflammable materials such as solvents in the vicinity when using

the pump.

(3) Ensure that the motor is freely ventilated to prevent overheating which may result in fire or

burns.

Power Supply

(4) Always remove the power cord from the terminal before checking or repairing the pump.

Failure to do so may result in electric shock, or the pump suddenly starting and causing

injury.

(5) Ensure that the relevant wiring is in accordance with technical standards for electrical

equipment and wiring regulations. Incorrect wiring may result in fire.

(6) Always remove the power cord from the terminal before electric wiring. Connecting wiring

with the power on may result in electric shock.

(7) Always ensure that the pump is correctly earthed. A dedicated earth leakage breaker is

recommended. Failure to earth the pump correctly may result in electric shock if a fault or

earth leakage occurs.

(8) Use the pump only at the rated voltage. Use at other than the rated voltage may interfere

with operation of the overload protection device, and this may result in the motor burning

out, or fire.

(9) Do not damage, modify, pull the power cord, or place objects on it. Damage to the cord may

result in electric shock or fire.

Danger

Warning

Power Supply

(10)When attaching the main power cord to the pump,

please use the power cord which meets the rated

voltage and current, pursuant to the provision.

4-Core-cable(Size of the wire lead: 1.0m㎡or larger,

300V or more, 10A or more, 100℃or higher, one

earth cable included)

Ensure that one of the core wires is used as an earth

wire. Firmly attach the 6 - 12mm diameter Cable gland

compatible cable fitted with the appropriate terminals

(M3 terminal block screws) to a terminal block.

Tighten the cap of the cable gland by max 2.5N･m.

Failure to follow these requirements may result in

electric shock.

Wiring and ground construction should be done subject

to your local law and the safety requirements.

The wire with insulation having an outer surface that is

green with or without yellow stripes is the grounding

wire.

(11)Switch off the main power supply, before disconnecting the power wire from the pump.

Failure to do so may result in electric shock.

(12)Touching the power cord with wet hands may result in electric shock.

(13)Touching electrical wiring etc while inserting the power cord may result in electric shock.

(14)The electric motor fitted to this pump incorporates a thermal protector; however it is not

guaranteed to be open when it eventually fails at some time. For safety reasons therefore, it

is necessary to fit an overload (over current), protection device and an earth leakage

breaker.

Operation

(15)This pump is not designed to be explosion-proof. When using the pump, ensure that there

are no inflammable materials such as solvents, or explosive gases, in the vicinity. Use under

such conditions may result in injury or fire.

(16)Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire.

(17)Operating the pump with the discharge outlet blocked, or with a device which prevents

passage of gas to the discharge outlet, may result in rupture of the pump. The internal

pressure of the pump rises and the pump body may rupture and the motor become

overloaded.

This pump is not designed to be pressure-resistant. The internal pressure of the pump is

limited to 0.03 MPa (gauge pressure).

Maintenance and Repair

(18)The pump should be dismantled or repaired only by a repair technician trained by the

manufacturer.

(19)To prevent ingestion of microscopic particles resulting from wear of components, use a dust

mask and gloves during repair work.
