Precautions For Maintenance And Operation; Cleaning The Main Unit - JRC JRL-2000F Manual

9.1 Cleaning the Main Unit
The JRL-2000F has two internal ventilation fans. They draw in air from the front panel and
expel ~t through the rear panel.
An air filter is mounted on the intake vent at the front panel so that dirt or dust will not enter
the main unit.
Examine the condition of air filter behind the intake vent of the front panel and occasionally
clean the air filter.
At the same time, clean the louvered area of the intake escutcheon, and the guard and propellers
of the ventilation fans to remove any dust and dirt.
Close attention should be paid to the air filter because if it becomes clogged, the internal
cooling performance declines, which may result in an alarm or machine failure.
The air filter should be removed in the following manner:
@
Turn off the power supply to the JRL-2000F and unplug the power cord from the outlet.
@
Remove the screws from the intake vent and pull out the air filter.
