5.4 EverFRESH Air Valve (EA)
Refer to Warnings in the beginning of this
section before performing maintenance.
The EverFRESH Air Valve (EA) (
) maintains the desired oxygen levels inside the cargo space. When
the controller detects that oxygen levels are dropping below the threshold setting, it will open the EA valve to force
the clean, dry, pressurized, air into the cargo space.

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
