Installation Instructions for the Keep the Heat™ (formerly Neu-Air™) Air-To-Air Heat Exchanger  

What's Included:

• 1 Neu-Air™ Air-To-Air Heat Exchanger

• 1 Chute, 20 foot long

• 11 3" to 3" ADS (Advanced Drainage Systems) adapters to attach the head to the chute tubes

• 75 ring spacers tobe attached to the internal 3" ADS tubes

• We have put the 11 3" adapters inside the housing unit and the ring spacer shipping purposes

What you need to provide:

1. 11 pieces of 3" ADS (Advanced Drainage Systems) corrugated tubing 23' long (these lie inside the 20' chute that is included)

2. When those 11 3" pieces of corrugated tubing come out of the end of the chute, we usually connect thin wall 4" PVC or other material to air delivery tubes that run across the ceiling and down the sidewalls or poles.  A typical installation uses about 750' of PVC.

3. Support hangers to support the 20' chute and hangers for the 11 air delivery tubes.

Installation Instructions:

1. Build a flange to mount in your building.  (See Picture).

2. Cut the hole in your building, insert flange and attach to your building.

3. Place "ring spacers" every three to four feet on the eleven 3" tubes.

4. Insert head of the unit into the building.  Attach unit to building and flange.

5. Raise 10' section of the chute to the ceiling level.

6. Attach 3" couplers from the head of unit to the ADS tubes located in the chute.

7. Attach "non flanged" end of ductwork to the head of unit.

8. Attach flange to flange of the chute.  The third flange goes on the very end of the chute.

9. Add additional tubing or PVC as needed.  Some of our customers have used PVC or corrugated tubing and some have used a combination of these.

10. Have electrician wire switches. We suggest using separate switches for each motor.  The motors are variable speed.  Install speed control, if desired.
