Preface

Warranty

Products manufactured by Seller are warranted against defects in materials and workmanship for twelve

(12) months from date of shipment thereof to Customer, and Seller’s liability under valid warranty

claims is limited, at the option of Seller, to repair, to replace, or refund of an equitable portion of the

purchase price of the Product. Items expendable in normal use are not covered by this warranty. All

warranty replacement or repair of parts shall be limited to equipment malfunctions which, in the sole

opinion of Seller, are due or traceable to defects in original materials or workmanship. All obligations of

Seller under this warranty shall cease in the event of abuse, accident, alteration, misuse, or neglect of

the equipment. In-warranty repaired or replaced parts are warranted only for the remaining unexpired

portion of the original warranty period applicable to the repaired or replaced parts. After expiration of

the applicable warranty period, Customer shall be charged at the then current prices for parts, labor,

and transportation.

Reasonable care must be used to avoid hazards. Seller expressly disclaims responsibility for loss or

damage caused by use of its Products other than in accordance with proper operating procedures.

Except as stated herein, Seller makes no warranty, express or implied (either in fact or by operation of

law), statutory or otherwise; and, except as stated herein, Seller shall have no liability under any war-

ranty, express or implied (either in fact or by operation of law), statutory or otherwise. Statements made

by any person, including representatives of Seller, which are inconsistent or in conflict with the terms of

this warranty shall not be binding upon Seller unless reduced to writing and approved by an officer of

Seller.

Warranty Replacement and Adjustment

All claims under warranty must be made promptly after occurrence of circumstances giving rise thereto,

and must be received within the applicable warranty period by Seller or its authorized representative.

Such claims should include the Product serial number, the date of shipment, and a full description of

the circumstances giving rise to the claim. Before any Products are returned for repair and/or adjust-

ment, written authorization from Seller or its authorized representative for the return and instructions as

to how and where these Products should be returned must be obtained. Any Product returned to Seller

for examination shall be prepaid via the means of transportation indicated as acceptable by Seller.

Seller reserves the right to reject any warranty claim not promptly reported and any warranty claim on

any item that has been altered or has been returned by non-acceptable means of transportation. When

any Product is returned for examination and inspection, or for any other reason, Customer shall be

responsible for all damage resulting from improper packing or handling, and for loss in transit, notwith-

standing any defect or non-conformity in the Product. In all cases, Seller has the sole responsibility for

determining the cause and nature of failure, and Seller’s determination with regard thereto shall be

final.

If it is found that Seller’s Product has been returned without cause and is still serviceable, Customer will

be notified and the Product returned at its expense; in addition, a charge for testing and examination

may be made on Products so returned.

Hazard and Safety Information

This manual uses the following standard safety protocols:

WARNING The warning messages are for attracting the attention of the

operator to a particular procedure or practice which, if not

followed correctly, could lead to serious injury.

CAUTION The caution messages are displayed before procedures, which

if not followed, could cause damage to the equipment.

NOTE The notes contain important information.

Operators and service personnel must be aware of all hazards associated with this

equipment. They must know how to recognize hazardous and potentially hazardous

conditions, and know how to avoid them. The consequences of unskilled, improper, or

careless operation of the equipment can be serious. This product must only be operated and

maintained by trained personnel. Every operator or service person must read and

thoroughly understand operation/maintenance manuals and any additional information

provided by Varian Vacuum Technologies. All warning and cautions should be read

carefully and strictly observed. Consult local, state, and national agencies regarding specific

requirements and regulations. Address any safety, operation, and/or maintenance questions

to your nearest Varian Vacuum Technologies office.

EMC Warnings

EN 55022 Class A Warning

This is a Class A product. In a domestic environment this product may cause radio

interference in which case the user may be required to take adequate measures.

FCC

This device complies with Part 15 of the FCC rules. Operation is subject to the following

two conditions: (1) This device may not cause harmful interference, and (2) this device must

accept any interference received, including interference that may cause undesirable

operation.

NOTE The equipment has been tested and found to comply with the

limits for a Class A digital device, pursuant to Part 15 of the FCC

rules. These limits are designed to provide reasonable

protection against harmful interference when the equipment is

operated in a commercial environment. This equipment

generated, uses, and can radiate radio frequency energy and, if

not installed and used in accordance with the instruction

manual, may cause harmful interference to radio

communications. Operation of this equipment in a residential

area is also likely to cause harmful radio communications

interference in which case the user will be required to correct

the interference at his own expense.

Installation Requirements

To maintain compliance with both the FCC Part 15 rules and the European Union’s EMI

directives, the user must use a shielded cable constructed of a braided shield and metal or

metalized plastic backshells directly connected to the cable shield at the 15 pos D-Sub

connector of the Eyesys Mini-BA. The shield must be connected to ground at the user’s

equipment. Failure to install the equipment in this way may result in the unit no longer

meeting the requirements for radiated emissions and susceptibility.

Eyesys Mini-B/A Gauge Controller

Use with Combustibles and Mixtures

WARNING As with all ionization gauges, this device is not intrinsically

safe. Exercise extreme care when using this vacuum gauge

while pumping or backfilling a system or in any other system

condition which contains combustible gases or mixtures. The

filament, the end of a hot filament ion gauge and the high

voltage discharge of a cold cathode gauge can be ignition

sources.

When such a gas or mixture is present, do not turn on any such

vacuum gauge.

Failure to follow this instruction could result in serious injury to

personnel and damage to equipment.

Vacuum Equipment and Cleanliness

Cleanliness is vital when servicing any vacuum equipment.

CAUTION Do not use silicone oil or silicone grease.

Use powder-free butyl or polycarbonate gloves to prevent

skin oils from getting on vacuum surfaces.

Do not clean any aluminum parts with Alconox®. Alconox

is not compatible with aluminum and will cause damage.

NOTE Normally, it is unnecessary to use vacuum grease.

However, if it must be used, do not use silicone types, and

use it sparingly. Apiezon®L grease is recommended

(Varian Part Number 695400004).
