Removing the EverFRESH Nitrogen 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 Nitrogen Valve (EN)
nent can be accessed from the front of the unit through the upper left access panel, or from inside the con-
tainer through the EverFRESH access panel door.
2. Place cardboard on the evaporator to protect it from any components or tools that may fall.
3. When removing from the upper left access panel, remove the EA valve assembly first for easier access. Do
not cut the wires on the EA coil. Removing the evaporator fan motor will allow for more space but not neces-
sary. When removing from the back of the unit through the EverFRESH access panel, access to the compo-
nents is easier.
4. Remove the hoses from both sides of the EN.
5. Cut the wire ties holding the EN coil wires to the harness back to where the coil is spliced into the unit. Then,
cut the wires at the harness splice.
