Maintenance

Hood Access

To access the throat of the unit, take the entire hood off

by removing the bolts attaching the mounting bracket to

the mounting channels. GR units with less than a 73" throat

length and GI units with less than a 61" throat length can

be hinged. Hinging is accomplished by removing the bolts

on one side and loosening the two bolts (Refer to figure 2)

on the other side. Care should be taken when hinging the

hood, especially in high wind conditions.

Filters

Filter inspection and cleaning intervals can vary from

once a week to twice per year depending on contaminant

present and acceptable pressure drops across the filter.

Under most conditions filters may be cleaned with hot water

and a mild soap solution (such as dish washing liquid) or

steam. Some caustic cleaners will damage the filter. If in

doubt, please consult the factory for a compatibility list.

High pressure spray washers should be limited to 2,000

PSI operating pressure. Every attempt should be made to

remove the contaminants from the filter in a "backwash"

flow (note airflow arrow on the filter frame). Once the filter

is dry, it may be returned to the appropriate filter racks

in the same orientation (airflow direction) as they were

removed.
