General Cleanliness
It is important that lint, dirt, dust, and foreign
materials do not enter the unit during operation.
General cleanliness prevents damage to
components, jamming, and soiling of flatwork.
Use a vacuum cleaner or compressed air supply
to clean the following:
• Front receiving shelf
• Rear receiving shelf on Type R units
• Feed ribbons and return ribbons
• Delivery ribbons on Type R units
• General components as required
CAUTION
Using compressed air on or
around electronic
component boards may
damage them.

Operation of the unit without
the filter could result in
failure of ignition, incomplete
combustion, and reduced
burner efficiency.

the burner can clog the
burner tips, requiring a
lengthy cleaning process,
including the complete
removal of the burner.
Each day it is critical to inspect and clean the
combustion blower air filter. Daily PM is required
to prevent lint and dust from entering the burner.
1. Turn the power OFF at the main discon-
nect switch.
