Cooling system

The Sensor Portable Pack is cooled by a fan located on the
back panel. The pack's cooling fan draws air through the filter,
over the surfaces of the modules and then blows it out the
back of the pack. The fan runs when any of the dimmers in
the pack are on. They continue to run for three minutes after
all dimmers are off.
Warning: Never obstruct the fan exhaust by placing objects
that may block air flow behind your pack.
For optimum performance, the average ambient temperature
in an area where a Sensor Portable Pack is being used should
be about 68°F (20°C). Under no circumstances should the
ambient temperature be allowed to exceed 104°F (40°C).
Air filter
A door-mounted, electrostatic air filter removes dust and other
airborne debris from the cooling air. This filter must be kept
clean to ensure proper cooling. The filter should be cleaned
every six months (more often in dirty locations). Follow these
steps to clean the filter:
1. Open the door.
2. Brush or vacuum filter from both sides.
3. If a more thorough cleaning is necessary, use compressed
air to blow out embedded dust and dirt.
4. Close the door.
To remove air filter (for replacement or more thorough clean-
ing) follow these steps.
1. Open the door.
2. Use a Phillips-head screwdriver to remove the metal strip
holding down the left side of the filter.
3. Remove filter from door.
4. Reverse procedure to replace filter.
