unplug before continuing.

Cleaning the Unit

Remember to always wear an appropriate NIOSH-approved res-

pirator and other personal protective equipment when cleaning

or servicing the DefendAir. Clean the unit thoroughly after every

remediation job to avoid cross-contamination.

EXTERIOR: Wipe down the exterior housing with any non-

solvent-based cleaner. Pay particular attention to the area

around the air intake duct. Bring back the original factory shine

with an automotive vinyl cleaner or polish.

INTERIOR: Open the filter access panel and detach the back

panel. Remove the dirty filters. Wipe down the interior of the unit

with any non-solvent-based cleaner. Let the unit dry before in-

stalling clean filters. Reattach the back panel and close the filter

access panel.

Inspect the Electrical System

Inspect the electrical cord for damage at regular intervals. Peri-

odically, detach the back panel and inspect internal wiring for

bare wires, insecure fasteners, and discoloration. Remove and

repair any damaged wiring as needed. Failure to do so may lead

to electrical shock or a fire hazard.
