Air To Air Exchanger Tips
- Late Summer/early Fall remove core from air exchanger. Wash in laundry tub, air dry completely and return to air exchanger. Wash or shake out small foam filters. These filters should be removed and cleaned two or three times during the operating season.

- Wipe clean inside of unit seasonally.
- VERY IMPORTANT: Check outside air intake screen for blockages, brush or vacuum away any matted debris.

Check position of breakers in your electrical panel. They must be in the on position. Check fuse located in disconnect box. Disconnect box is located out by A/C unit.
- Be sure furnace filters are clean.
- Keep outside condensor coil clean. When unit is not running, take garden hose and flush clean, starting at top of unit and wash down.
- VERY IMPORTANT: Go to electrical panel and put A/C breaker in off position.
