Section 1 - Introduction

General

The manual provides instructions for installing, operating and servicing the

8510 High-Voltage Compressor, P/N 8031400G002 (380-460 volts). If you

are installing or operating an On-Board High-Vacuum System you should

also have available the On-Board High-Vacuum Pump Manual that applies

to your particular system:

• 8040215 On-Board 8 and 8F High-Vacuum Pumps

• 8040233 On-Board 10 and 400 High-Vacuum Pumps

The manuals for a system cover two basic components: the high-vacuum

pump and the compressor. Each manual outlines the details necessary for

installation, operation and servicing of that component. A manual is

shipped with each system component (high-vacuum pump and

compressor). When you purchase a system, you will receive the two

manuals necessary for system installation, plus a loose-leaf binder with

index tab separators, allowing you to compile a complete indexed system

notebook.

Installation, Operation and Service Instructions

Installation, Operation and Service Instructions for your 8510 High-

Voltage Compressor provide easily accessible information. All personnel

with installation, operation, and servicing responsibilities should become

familiar with the contents of these instructions to ensure high quality, safe,

reliable performance. Unit must be wired by an authorized electrician in

accordance with the national electrical code, ANSI/NFPA 70-1987, as well

as the local codes.

This compressor has been designed to operate with water having a pH

value of 6.0 to 8.0 and a calcium carbonate concentration of less than 75

parts per million (typical municipal drinking water quality). For

applications of lower pH or greater hardness, water conditioning may be

necessary.
