Maintenance
Air Filter
The frequency of cleaning depends on the environment around the CC-100. Usually,
whenever the velocity of air coming out of the CC-100 decreases, it is time to clean the
filter. Another indication is the rise in the outlet temperature above ambient. Normally
this temperature will be within a few degrees of ambient. The air filter is located in front
of the radiator. The easiest way of cleaning the filter is to vacuum it from the outside
without any disassembly of the CC-100. If this is not possible, the filter can be cleaned
by removing the top cover, removing the brackets holding the radiator in place, tilting
the top of the radiator away from the rear panel and removing the air filter. Once the
filter is removed, wash out the filter with tap water and allow it to dry before reinstalling
it.
Coolant
The antifreeze coolant needs to be maintained annually. A complete flush and refill is
recommended per instructions on the particular brand of antifreeze selected.
Coolant Pump
The top cover needs to be removed every six months and the pump oiled. The name plate
on the pump indicates the type of oil and the location for lubrication. Apply two or three
drops of oil into each location, essentially any type of S.A.E. 20 electric-motor oil can be
used.
