Daily maintenance
This section contains tasks that should be performed every day.
Inspect filters and replace as needed
FOLLOW GFS' RECOMMENDED REPLACEMENT PROGRAM FOR FILTERS. Use GFS replacement
filters for the plenum, the air heater, intake, exhaust, and other components as needed. GFS filters are
designed to provide high-efficiency particulate removal and will maintain balanced airflow during the life of
the filter.
All booths use these types of filters: air heater, intake, and exhaust.
The buildup of paint overspray on the exhaust filters must be monitored via an effective inspection program.

1
Change filters immediately if they become saturated sooner than the recommended replacement interval.
2
If coatings sprayed in the booth contain nitrocellulose, change filters at least daily.
NOTE
Some weather conditions (e.g., smog, fog, frost, etc.) produce atmospheric dust concentrations that may be
much higher than normal. In such conditions, intake filters and air heater pre-filters may become saturated
in a short time.
All filters should fit tightly in filter frames. If filters do not make a proper seal with the filter frames, unfiltered
air will pass to the next part of the system. Take extreme care to make sure intake filters are installed
properly. Improperly installed intake filters will allow unfiltered air into the booth's work area. This unfiltered
air may deposit visible dirt particles on the word surface and item being painted.
Keep a set of replacement filters on hand. For information on ordering filters, see “Consumable parts” on
page 21.
To ensure that maintenance procedures are followed correctly, have your local authorized and factory-
trained GFS distributor maintain your refinish system.
WARNING
Treat used filters and any other paint-contaminated items as flammable products and dispose of them
safely.
WARNING
If coatings containing nitrocellulose are sprayed in the booth, all residue must be removed from exhaust
diffuser components and all exhaust filters must be changed at least once a day.
