SECTION 12—HEAT EXCHANGER
ASSEMBLY

Replacing Heat Exchanger Assembly

DANGER

To prevent electrical shock, ALWAYS disconnect concentrator from electrical outlet
before servicing.

NOTE: For this procedure, refer to FIGURE 12.1 on page 53.

NOTE: The heat exchanger assembly contains three components: heat exchanger, nine inch vinyl
tube and connecting component.

1. Unplug unit.

2. Remove cabinet. Refer to Removing Cabinet on page 23.

CAUTION

Use care not to deform heat exchanger when installing, removing or cleaning.

3. Disconnect brass nut that secures the heat exchanger assembly to the compressor

(Detail “A”).

4. On the backside of the Perfecto2, loosen the clamp that secures the vinyl tube to the

manifold assembly and remove the vinyl tube from the manifold assembly. (Detail
“B”).

5. Remove heat exchanger assembly by pulling vinyl tube through sound box.

6. Reverse STEPS 3-5 to install new heat exchanger.

7. Run unit and check for leaks. Refer to Leak Test on page 77.

8. Reinstall cabinet. Refer to Removing Cabinet on page 23.
