4.3. Removal and Replacement Guidelines
R&R instructions are provided ONLY for components of MIV assemblies (in the form of bench
procedures). NO procedures are provided to R&R the MIV component from the apparatus. To re-
duce unnecessary work and to avoid the introduction of additional/new issues, only dismantle
the parts instructed and only when necessary to accomplish the target inspection and/or R&R.
4.3.1 Match Mark or Note Component Orientation
As a general maintenance practice, match mark and/or note (document/photograph/record) the
orientation of a component before disconnecting or removing it.
4.4. Troubleshooting
To troubleshoot the system, locate the SCR table (Table 5) listing the indicated SYMPTOM, verify
the associated CAUSE (verify ALL if multiple are listed) and perform the associated REMEDY.
The SCR tables assume a single fault and the SYMPTOM, CAUSE, and REMEDY columns have
been listed in a hierarchy order. Treat each SYMPTOM as the result of a single CAUSE, trace
through the SCR table until a single REMEDY is indicated. Perform the REMEDY, and then check
the system again. Determine if the same SYMPTOM exists, or a different SYMPTOM is now indi-
cated, or no symptoms exist.
If multiple faults exist, repeat following the table using multiple passes unless the REMEDY is al-
ways the same and does NOT remedy the symptom. When this occurs contact Hale Customer
Support (800–533–3569 or www.haleproducts.com) for further assistance.
