Removing the EverFRESH Air Valve

Make note of the direction arrow on the valve body to ensure proper direction of flow.
1. Open the panel needed to gain access to the EverFRESH Air Valve (EA)
be accessed from the front of the unit through the upper left access panel, or from inside the container
through the EverFRESH access panel door.
2. Place cardboard on the evaporator to protect it from any components or tools that may fall.
3. Disconnect the Membrane Pressure Transducer (MPT) harness.
4. Cut wire ties back to location where coil is spliced into the harness, cut the two lines at the harness crimp,
then remove the EA inlet hose using a 9/16" wrench to hold the brass fitting and 5/8" wrench to turn the
compression nut. Pull the hose away from the fitting.
5. Remove the three 1/4" x 20 screws with a 7/16" socket and remove the coil assembly.
6. To install, follow the removal steps in reverse.
When reinstalling the EA, remove the fittings from the existing valve body and place on the replace-
ment valve body. This is best suited to be completed on a work bench using wrenches. It is not recom-
mended to place the valve body in a vice as it could distort the valve preventing it from functioning
properly.
