WARNINGS AND CAUTIONS FOR SAFE USE

Failure to follow all of the warnings and cautions listed below may result in

damage to the instrument and/or serious personal injury. Tanaka Scientific

Limited will not assume any responsibility for faults or accidents arising from

failure to adhere to these instructions.

Installation Environment

! Warning: The instrument must be installed on a flat, sturdy surface

to prevent the instrument from falling over.

Coolant Circulation Piping

! Caution: Ensure that each joint in the coolant circulation piping is

securely fastened to prevent coolant leakage, as this may

result in instrument failure.

! Caution: Do not use methanol as cooling medium. O-ring of

solenoid valve may have damage and the unit will not work

correctly.

70% of ethylene glycol and 30% of distilled water mixture

will be the best for this unit.

Electrical Connection

! Warning: Observe the following instructions when handling power

cables and electric connections:

・ Do not connect or disconnect any cables or electrical

connections when the mains power is ON.

・ Do not handle any cables or electrical connections with

wet hands.

・ Be sure to use the plug to remove cables. Never use

the cord to pull a plug from an outlet.

・ Do not place heavy items on cords or cable.

- 3 -

・ Do not use force to bend any cords or cables.

・ Ensure that all electric connections (plugs, sockets,

connectors, etc.) are free of dust.

・ Keep all cables and electrical connections free of water

and other liquids.

・ Failure to adhere to the above precautions may result in

electric shock, damage to the instrument, cords and/or

cables, and/or fire due to overheating.

! Warning: Ensure that supply voltage meets the specifications of the

product. Do not turn the power on until all electric

connections are secured. Incorrect power supply

specifications or loose electric connections may damage

the instrument and result in electric shock and/or other

electrical accidents.

! Warning: Ensure all ground wires are securely grounded.

Loose or disconnected ground wires may result in electric

shock.

Never connect ground wires to gas pipes, as this may

result in fire or an explosion.

Ground wires may be connected to one of the following:

・ Ground terminal of a power outlet

・ Copper bar buried 65 cm or more underground

・ Water pipes as authorized by your local water bureau

as a grounding object

Handling Precautions

! Caution: Never press the START key unless coolant is circulating

normally. Starting the unit with no coolant present may

damage the thermo-module that cools and heats the bath.

! Caution: Ensure that an approximate pour/cloud point is entered

prior to every test run. If an appropriate estimation is not

- 4 -

entered or the value entered is much greater than the

actual pour/cloud point, the testing procedure may be

prolonged or produce incorrect results.

Operational Precautions

! Warning: If the instrument makes any abnormal noises or exhibits

any abnormal behavior, stop operation immediately, turn

the power off at the mains, and contact Tanaka Scientific

Limited or an authorized distributor.

Consumables, Accessories and Replacement Parts

! Caution: Use only Tanaka Scientific Limited genuine consumables,

parts and accessories or such parts as recommended by

Tanaka Scientific Limited.

Repairs, Alterations and Maintenance

! Warning: Do not make any modifications or alterations to the

instrument without the approval of Tanaka Scientific

Limited.

! Warning: Do not attempt to repair the instrument yourself. In the

event that the instrument exhibits any abnormal behavior

whatsoever, contact Tanaka Scientific Limited or an

authorized distributor.

! Warning: Only Tanaka Scientific Limited service personnel or

authorized representatives are to repair or maintain the

instrument.

2. Operational Principles

The MPC Series employs Tanaka Scientific's unique air pressure system (certified as U.S. standard

ASTM D 6749) to detect pour points (solidification points). Air pressure is applied to the surface of a

specimen, with subsequent motion of the sample surface measured to detect sample flow.

［System Outline］

The specimen chamber and specimen surface are divided into inner and outer regions by the pressure

conducting tube. Air pressure is applied to the specimen by a pressurizing syringe connected to the

outer region, creating a pressure differential between the inner and outer surfaces of the sample. Two

outcomes are then possible.

1. Specimen flow

The pressure differential causes the specimen to flow,

with the surface level inside the pressure conducting

tube rising (principle of the U-tube), causing a change in

pressure that is detected by the pressure sensor inside.

Upon a pre-determined pressure change, the pressure

switch is activated, indicating to the instrument that the

specimen is still flowing.

2. No specimen flow

When the specimen is not flowing, the specimen surface

levels do not change despite the pressure differential.

Thus, the pressure inside the pressure conducting tube

remains unchanged and the pressure switch is not

activated. Specimen flow is assumed to have stopped if

the pressure switch is not activated within five seconds.
