4.4 Front Door Filter (RM476)

You can easily remove the filter on the front door to clean or replace it. The part number for the front door filter is RM476. To remove the filter, remove the two wing nuts on the top of the filter, swing the filter bracket down and remove the filter. See Figure 4-2.

The life of the filter depends on the environment the ServShield is installed in. You can vacuum the filters or wash them in warm water with mild detergent. We recommend vacuuming the filter to keep it in peak condition. If you choose to wash the filter, do so only once and replace it with a new filter when it gets dirty again.
