Section 4: Disassembly and Component Cleaning

WARNING

Fuels and solvents are flammable and may cause

irritation to the eyes or skin. Wear protective gog-

gles, gloves, and an apron; avoid contact with skin,

eyes, and clothing. Use in well ventilated areas and

keep away from heat or flame. Follow all Material

Safety Data Sheet (MSDS), Hazardous Materials

Identification System (HMIS), ISO 9000, Lab Stan-

dard Operating Procedures (SOP), and related in-

structions. Failure to comply may result in person-

nel injury or death.

The heater tube test section can reach high

tem-peratures of 1

–380 °C during operation.

Always place bus bar cover over the heater tube

test area when running test to prevent contact

with the test section. When the bus bar cover is

removed, al-ways assume the heater tube test

section is hot and use caution when operating

around this area.

4.1 Unit Disassembly

Position a waste solvent container as needed to

catch solvent during the component cleaning.

The heater tube must be removed and rated.

Allow the heater tube assembly to cool for

15 minutes before continuing.

Lift and rotate the heater tube thermocouple

retaining clip off the thermocouple and carefully

remove the thermocouple tip from the hole on

the top of the heater tube taking care not to bend

the thermocouple.

Wipe down the thermocouple using a

germicidal wipe.

Remove the fuel-out line from the DP- fitting and

the fuel bypass lines from the DP+ fittings.

Remove the prefilter assembly from the cabinet

bulkhead.

Remove the right upper and lower bus bar screws

with the hex wrench provided

[Figure 49]

Loosen the left hand screws on the upper and

lower bus bars but do not remove

[Figure 49]

Remove the test section assembly.

10.

Remove the fuel-out line (J-line) from the heater

tube housing and place in the pan provided.

11.

Remove the O-ring and the DP filter from the DP

filter housing using the extraction tool provided.

Discard the used O-ring and the DP filter.

12.

Remove the hex nuts and the upper insulator

bushings from both sides of the heater tube

housing and place them in the pan provided.

Remove and discard the O-rings.

13.

Remove the lower insulator bushings from both

sides of the heater tube and the heater tube

housing and place them in the pan provided.

14.

Carefully slide the heater tube out of the housing.

NoTe:

Lower insulator bushings may come out of the

heater tube housing while removing the heater tube or

they may stay in the heater tube housing. Take care not

to lose them.

15.

Rinse the heater tube with Iso-Octane and allow

the solvent to evaporate. Place the heater tube

back in the original plastic container and cap until

you are ready to rate the tube.

16.

Rate the tube using an approved method and

record value on screen.
