Maintenance

8.0 Maintenance
With care, the HPC will require little or no maintenance. However periodic electrical
safety checks may be required by law in some countries.
8.1

External Cleaning

If the front panel requires cleaning, wipe with a mild detergent on a damp soft cloth.
DO NOT allow liquids into the chassis.
DO NOT spray liquids onto the front panel.
DO NOT use solvents for cleaning the front panel.
8.2

Internal Cleaning

The HPC will require little internal maintenance other than periodic flushing to prevent
the fan and air-path becoming clogged with dirt or fluff.
1. ISOLATE POWER to the dimmer (by disconnecting the power cable or locking
2. Remove the lid.
3. Blow clean the fan and internals with compressed air from left to right. DO
4. When the fan and internals are clean, replace the lid and screws, and re-

Routine Maintenance

Installed HPC's should be routinely flushed of dust at six- to twelve-month periods.
Touring HPC's may need a more rigorous maintenance routine, which should include:
• Inspection of chassis for evidence of impact damage and physical abuse
• Inspection of outlets for wear and damage
• Inspection of power cable for wear and damage
• Electrical checking of ground integrity from power cable to chassis
• Electrical checking of ground integrity from power cable to outlet grounds
• Flushing of dust build-up
• Testing the operation of all front panel switches and breakers
A Neutral-Earth test may show a low reading. This is normal and is a consequence of
the N-E voltage detector detailed in Section 6.4.
