The user will need to clean the P3 PowerPort 1500 periodically, and may replace fuses in the fuseholders on

Fuse replacement
Warning! Replace fuses with fuses of the same type and rating only.
The P3 PowerPort 1500 is protected by four 10 amp slow-blow fuses located in fuseholders on the rear
panel (see Figure 2 on page 7). If one of the outputs – or the entire device – stops working, a fuse may have
blown. Fuses in group 1 protect outputs 1 and 2. Fuses in group 2 protect outputs 3 and 4.
To replace a fuse:
1. Disconnect the P3 PowerPort 1500 from power.
2. Using a flat-head screwdriver, turn each fuseholder cap counter-clockwise to release it, then remove
each fuse.
3. Replace defective fuses with fuses of the same type and rating. Replacement fuses are available from
Martin™ suppliers (see "Spare Parts" on page 18).
4. Reinstall all fuseholders before reapplying power.
Cleaning
Cleaning schedules vary greatly depending on the operating environment. It is therefore impossible to
specify precise cleaning intervals for the P3 PowerPort 1500. Cooling fans suck in airborne dust and smoke
particles, and in extreme cases, the product and its air filters may require cleaning after surprisingly few
hours of operation. Environmental factors that may result in a need for frequent cleaning include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and fittings or the natural environment in outdoor
locations, for example).
If one or more of these factors is present, inspect products within their first 25 hours of operation to see
whether cleaning is necessary. Check again at frequent intervals. This procedure will allow you to assess
cleaning requirements in your particular situation. If in doubt, consult your Martin™ dealer about a suitable
maintenance schedule.
