You should clean the Merlin system units often enough to prevent dust or dirt from
accumulating. Dirt acts as a thermal insulating blanket that prevents effective heat dissipation
and may provide high-resistance electrical leakage paths between conductors or components
in a humid environment.
Clean the dust from the outside by wiping with a soft cloth or small brush. A brush is
especially useful for removing dust from around connectors and cooling grilles. Use a cloth
dampened in water that contains 50% Isopropyl alcohol to remove hardened dirt. You should
not use abrasive cleaners.

To ensure good airflow through the Engine, the air filter in the front panel must be
periodically cleaned. It is usually sufficient to simply remove accumulated dust using a
vacuum cleaner to suck it out of the front panel grille. From time to time, however, the front
panel will have to be removed to give the filter a thorough clean or even replace it altogether.
The front dress panel should removed to allow access to the Air Filter.
1. Gently lift the dress panel away from the Engine.
2. Unclip the Air Filter and remove it from the front facia of the 2nd panel.
3. Once the air filter has been removed, clean it thoroughly by washing it in warm water
with mild detergent. Make sure it is completely dry before reinstalling it.
CAUTION: DO NOT ALLOW WATER TO GET INSIDE ANY ENCLOSED ASSEMBLY OR
COMPONENT. DO NOT CLEAN ANY PLASTIC MATERIALS WITH ORGANIC CLEANING
SOLVENTS, SUCH AS BENZENE, TOLUENE, XYLENE, ACETONE, OR SIMILAR COMPOUNDS,
BECAUSE THEY MAY DAMAGE THE PLASTIC. CAUTION: DO NOT USE CLEANING FLUIDS,
OTHER THAN THOSE MENTIONED IN THE GRAPHICS MONITOR MANUAL, TO CLEAN THE
SCREEN - THE SPECIAL COATING COULD BE DAMAGED.
