General Maintenance, Continued

To gain access to the modules, the electronic enclosure door must be

opened. It will be necessary to use a #4mm Allen wrench to open the

door if the Allen screw on the latch has been tightened.

Opening Doors

After performing any maintenance function(s), check to be certain there

is no loose hardware left within the electronic enclosure. Such items can

create electrical shorts causing damage to internal components. This

increases system downtime for performing of corrective maintenance.

Inspection After

Maintenance

Recommended tools for performing maintenance are as follows:

Field Tool Kit

• Maxum II Tool Kit

• Set of metric Allen wrenches

• Set of metric wrenches or nut drivers

Note: Special tools required for specific procedures within this section

are noted within the procedure (example: torque wrenches

required for valve assembly).

It is important for proper procedures to be used when cleaning valve and

detector parts. All foreign contamination adhering to the part should be

removed using an appropriate cleaning solvent, such as hexane,

acetone, or methanol and a dust/lint free cloth. Use of an ultrasonic

cleaner is often helpful. After cleaning, it is necessary remove excess

cleaning fluid from the components by blowing with clean air or shaking.

Components must be air dry before reassembling.

Use of Solvents and

Detergents

It is also possible and often better to use an appropriate detergent, such

as Alconox®, for cleaning instead of solvent. However, after cleaning

with a detergent, it is necessary to rinse the part thoroughly with

deionized water (distilled water is also acceptable) in order to remove

detergent residue. All water must then be removed by blowing with

clean air or shaking. Components must be completely dry before

reassembling.
