Clean the Air Filter
Inspect and clean the rear-panel air filter at least once a year, or as necessary, to
ensure adequate air circulation. If the rear panel filter air flow is obstructed, have
the internal filter cleaned by a qualified technician using the procedure described
below.
To get to the rear-panel filter:
1. Turn off the Product.
2. Remove the power cable.
3. The filter is held in place by a clip-on plastic cover. Remove the cover by
squeezing and pulling the top two corners of the cover. It is not necessary to
remove the Product covers.
4. Remove the filter gauze.
To clean and refit the filter gauze:
1. Clean the air filter with a dry brush or vacuum cleaner. If necessary, warm
water and a mild detergent can be used.
2. Dry the air filter with a paper towel.
3. Replace the gauze filter into the plastic cover.
4. Re-fit the plastic cover.
Replace the Line-Power Fuses
 Warning
To prevent fire hazard or damage to the Product, verify that the
correct fuses are installed. See Table 5-1 for the correct fuse
ratings.
Fuse replacement is necessary if the Product blows a fuse. The line-power fuses
are located on the power block on the rear panel. See Figure 5-1. The Product
has dual fusing with fuses in both the line and neutral connections. When a
blown fuse is replaced, replace both fuses to avoid a stressed fuse and
subsequent power interruption. Before you try to access and replace the fuses,
make sure that the replacement fuses are appropriate.
To check or replace the fuses:
1. Disconnect the Product from line power. Remove the mains power cord from
the Product inlet.
2. To remove the combined power switch/fuse compartment, insert a
screwdriver blade in the tab located on the left or right of the compartment.
Gently pry until the compartment can be easily removed.
3. Pull the fuses from the compartment for replacement or inspection.
4. Install good fuses with the correct ratings. See Table 5-1 and Figure 5-1.
5. To reinstall the compartment, push it back into place until the tab locks.
