MAINTENANCE MANUAL

Safety Considerations

To ensure operation safety, this instrument must be operated correctly and

maintained regularly according to schedule. Carefully read to fully understand all

safety precautions in this manual before operating the instrument. This manual

denotes precautions against actions that can result in hazardous situations or

equipment damage by using the signal words WARNING, CAUTION, and Note.

(1) Safety symbols

Instruction manual symbol. If the product is marked with this symbol,

refer to the instrument manuals to protect the instrument against

damage.

WARNING A WARNING indicates an potentially hazardous situation which, if not

avoided, could result in death or serious injury

CAUTION A CAUTION indicates a potentially hazardous situation which, if not

avoided, may result in minor or moderate injury. It may also be used

to alert against unsafe practices.

Do not proceed beyond a WARNING or CAUTION notice until you

understand the hazardous conditions and have taken the appropriate

steps.

Note A Note provides additional information to aid the operator in obtaining

optimal instrument performance.

Pressurized, hazardous solvents are used in high-performance liquid

chromatography. Always follow the proper laboratory procedures to ensure operator

safety. Always wear goggles, gloves and protective clothing when operating the

instrument, especially when injecting sample and opening valves.

(2) Warning Labels

Warning labels are attached at several locations on this instrument. Do not remove,

deface or damage the warning labels. If a warning label peels off the instrument or

becomes illegible, contact your local JASCO distributor (See list on the back cover of

this manual) for a replacement label. Be sure to indicate the part number (P/N) on

the label.

(1) Fuse Warning Label (P/N: 0822-0120A)

Fuse ratings are indicated in the maintenance

manual.

(2) Electric Shock Warning Label (P/N: 0822-0125A)

Electric shock may occur if the instrument is not

properly grounded.

Since water pipes are often constructed of non-

metallic materials (e.g., polyvinyl chloride), do not

use these pipes for grounding purposes.

For safety reasons, do not use gas pipes for

grounding purposes.

Preface

This instruction manual serves as your guidebook for using this instrument. It is

intended to instruct first-time users on how to properly use the instrument, and to

serve as a reference for experienced users.

Before using the instrument, please read this instruction manual carefully, and make

sure that the contents are fully understood. This manual should be easily accessible to

the operator at all times during instrument operation. When not using the instrument,

keep this manual stored in a safe place. Should this instruction manual be lost, order a

replacement from your local JASCO distributor.

The manuals for this instrument consist of an operations manual and a maintenance

manual. This is the operations manual.

Installation Conditions

To ensure safe operation, the following recommendations should be observed:

(1) Do not operate the instrument under voltage fluctuations exceeding 10%

of the recommended line voltage. Large fluctuations may cause the

instrument to fail.

(2) Use a three-pronged electrical outlet with a ground. When only a two-

pronged socket is available, use an adapter and be sure to connect the

ground wire of the adapter.

(3) Operate the instrument under a temperature range of 10 ∼30°C.

(4) Operate the instrument under a humidity range of 35 ∼85% (RH). If

ambient humidity exceeds 85% (RH), water vapor may deteriorate optical

components. If possible, install the instrument in a location having a

humidity of 60% or lower.

(5) Operate the instrument under an atmospheric pressure of 750 ∼1060 hPa.

(6) Avoid strong magnetic fields and sources of high-frequency waves. The

instrument may not function properly when near strong magnetic fields or

high-frequency wave sources.

(7) Avoid vibrations caused by vacuum pumps, electric motors, processing

equipment and machine tools.

(8) Avoid dust and corrosive gas. Do not install the instrument in a location

where it may be exposed to dust, especially in locations exposed to

outside air or ventilation outlets that discharge dust particles.

(9) Do not install the instrument in a location where it may be exposed to

direct sunlight.

(10) Do not install the instrument in a location where it may be directly exposed

to the air current from an air conditioner or heater, as such a location may

inhibit stable measurement.

Note: The above conditions do not ensure optimal performance of this instrument.

Maintenance

Consult your local JASCO distributor, listed at the back of this manual, regarding

maintenance. In addition, contact your local JASCO distributor representative when

transporting the instrument.

Replacement parts can be ordered according to part number from local JASCO

distributor. When the part number is not known, inform parts name,instrucment

model name and it’s serial number.
