Installation & Operation Manual
5.9.6. MAINTENANCE
The most critical item to be maintained is the filter on the Flow Path Pressure Generating fan (see
Figure 6, page 7). The filter is held in place by a snap-on fan guard and can be washed several times.
Regular cleaning of the Flow Path Pressure Generating fan filter is important to maintaining air
circulation within the control box and providing combustion air. Air circulation will help extend the life
of components and avoid oven down time. Depending upon store conditions, this filter should be cleaned
weekly or as it gets clogged with dust. After several cleanings the filter will need replacement. These can
be ordered directly from XLT at 1-888-443-2751 or can be purchased from your local Grainger store; part
number 4YD83 or 4YD84. Remember, the cleaner the filter, the cooler the control box components
will be, resulting in longer component life.
