A.2.5 Every 250 hours (or 1 month <strong>of</strong> use): cooling<br />

fan filter<br />

Maintenance<br />

1. Remove the cooling fan cover from the back <strong>of</strong> the ventilator by<br />

loosening the two screws (see Figure A-2).<br />

2. Remove the cooling fan filter, wash in a mild detergent<br />

solution, rinse well, then dry thoroughly. Replace filter if it<br />

appears worn or occluded, or a FAN FAILED ALERT alarm occurs.<br />

3. Replace the cooling fan filter inside the cooling fan cover.<br />

4. Reposition the cooling fan cover and tighten the two screws<br />

(see Figure A-2).<br />

NOTE:<br />

Clean the filter more <strong>of</strong>ten than every 250 hours (or 1 month<br />

<strong>of</strong> use) if necessary, or when the ventilator displays the FAN<br />

FAILED ALERT message. (Some environments cause lint and<br />

dust to collect more quickly.)<br />
