1.1 Scope and definitions

This manual provides installation, operation and maintenance instructions for the Edwards

Turbomolecular Pump (abbreviated to "STP pump" throughout this manual). In this manual, the

control unit for the turbomolecular pump is referred to as the "STP control unit". You must use the

STP pump as specified in this manual.

The procedures in this manual must be followed before you install, operate and maintain the STP

pump. Important safety information is highlighted as WARNING and CAUTION instructions; these

instructions are mandatory. The use of WARNINGS and CAUTIONS is defined below:

WARNING

Warnings are given where failure to observe the instruction could result in serious injury

or death to people.

CAUTION

Cautions are given where failure to observe the instruction could result minor personal injury in

damage to the equipment, associated equipment and/or process.

Note: Items you must follow during operation and maintenance.

Throughout this manual, page, figure and table numbers are sequential.

The units used throughout this manual conform to the SI international system of units of

measurement; US equivalent units of measurement are also given.

The following IEC warning labels/symbols appear on the STP Pump Instruction Manual:

Warning - refer to

accompanying documentation.

Warning - risk of electric shock.

Warning - heavy object.

Note: An alarm function is incorporated into this STP series. Alarm and cautionary messages are

displayed on the LCD of the STP control unit. Note that the words "WARNING" and

"CAUTION" displayed on the LCD indicate the need for overhaul of the pump or precautions

during the operation. They do not have the same meaning as the much more serious

symbols for "WARNING" and "CAUTION" used in the instruction manual.

INTRODUCTION

1.4 Precautions for safe operation of the STP pump

1.4.1 Usable gases

1. Chlorine or fluorine system gases can be used in corrosion resistant pumps. When you use the

following gases, contact Edwards.

•Gases including alkaline metals except Li gas.

•Gases including Ga, Hg, In, or Sn.

•HBr gas.

2. Non-corrosion resistant pump cannot use the above gases including chlorine and fluorine system

gases.

WARNING

To prevent an accident, confirm the characteristics of gases to be used, referring to the

Material Safety Data Sheet (MSDS) you obtain from the gas supplier, and, keep MSDS

and a safety advice of gas supplier.

WARNING

Warn of the danger of the gas with the warning label when the use gas is hazardous

WARNINGchemical material.

WARNING

Secure safety by wearing personal protective equipment when using the gas which

might influence damage health. In addition, take appropriate measure for depending

upon the properties of the gas to be used.

CAUTION

NEVER use any gas that is not specified as usable in this Manual. The use of such gas may

CAUTION corrode the STP pump and damage it.

CAUTION

Introduce a dry N2gas (purge gas) to protect the inside of the STP pump when using reactive or

corrosive gas. The use of reactive or corrosive gas may result in product damage.

CAUTION

Cool the STP pump to prevent the STP pump from overheating when pumping gases.
