Maintenance
Clean the window regularly to maintain picture clarity. Use a soft cloth and a mild, nonabrasive detergent and water.
The desiccant canister reduces condensation within the enclosure. When the orange beads in the inspection window become clear, reactivate
the desiccant canister by placing it in a vented 150°C (300°F) oven for at least three hours, or until the beads are orange.
FH-H Series: Perform periodic maintenance to inspect and remove debris from the exterior fan and cooling device area to maintain proper
operation and prolong the operational life of the enclosure system. Compressed air can be used to remove dirt and debris. It is recommended that
the power be disconnected before maintenance is performed.
