Preface

This manual provides the information you need to successfully perform replacement of the entire

module of your Varian TriScrollTM Dry Vacuum Pump. Module replacement is performed as an

alternative to performing a complete overhaul and rebuild (Major Maintenance) and is sold as one of

the options recommended when the pump base pressure has risen to an unacceptably high level for

your application. If you have questions that are not addressed in this manual, please contact the nearest

Varian Vacuum Technologies service facility listed on the rear cover of this manual.

Safety Considerations

READ THE FOLLOWING INSTRUCTIONS. TAKE ALL NECESSARY PRECAUTIONS.

The following format is used in this manual to call attention to hazards:

Maintenance 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 work performed by unskilled or improperly trained maintenance personnel, or

careless operation of the equipment employed in the specified maintenance procedures can be serious.

Every maintenance person must read and thoroughly understand the materials discussed and the

instructions provided in this manual, as well as any additional information provided by Varian Vacuum

Technologies.

All warnings and cautions must be read carefully, fully understood, and strictly observed. Consult local,

state/province, and national agencies regarding specific requirements and regulations. Address any

safety, operation, and/or maintenance questions to the nearest Varian Vacuum Technologies location.

WARNING The warning messages are for attracting

the attention of the operator to a partic-

ular procedure or practice which, if not

followed correctly, could lead to serious

injury.

CAUTION The caution messages are displayed

before procedures, which if not fol-

lowed, could cause damage to the

equipment.

NOTE The notes contain important informa-

tion taken from the text.

vii

TriScroll 300 Dry Scroll Vacuum Pump

WARNING Disconnect power from the

TriScroll 300 before performing any

maintenance procedure.

Allow the pump to cool before perform-

ing any maintenance procedure.

Approximate cool-down time is one to

two hours.

CAUTION Wipe all O-rings clean with a lint-free

cloth before installation to ensure that

no foreign matter is present to impair

the seal.

Do not use alcohol, methanol or other

solvents on O-rings. To do so causes

deterioration and reduces their ability to

hold a vacuum.

If applicable, apply a small amount of

Krytox®GPL 224 grease and wipe the

O-rings “shiny” dry.

NOTE Varian Vacuum Technologies recom-

mends replacing all O-rings during rou-

tine maintenance or during any

maintenance procedure requiring that

O-rings be removed.

Unless otherwise stated, apply

Loctite®242 or Loctite PST®567 to the

first few threads only. Apply just enough

to obtain a seal.

WARNING The TriScroll 300 weighs 26.4 kg

(58 lbs). To avoid injury, use proper lift-

ing techniques when moving the pump.

General Information

Varian TriScroll 300 series pumps are designed to provide years of trouble-free service if maintenance

procedures and intervals are observed. Bearing grease replenishment and tip seal replacement is

recommended when the pump base pressure has risen to an unacceptably high level for your

application. Bearings, rotary seals and O-rings should also be replaced if the pump exhibits humming

or grinding noises from the bearings. Main bearing life may be shortened if your application requires

the pumping of high quantities of water vapor. Use of the bearing purge will keep this water from

impacting bearing life.
