CAUTION - alert to potential hazard or unsafe practice that could result in minor personal injury, product or property damage. The following safety statements are applicable to the EverFRESH option unit used with any container unit and appear elsewhere in this manual. These recommended precautions must be understood and applied during operation and maintenance of the equipment covered herein.
Page 8
CAUTION Do not run the Calibration tests under loaded conditions. While the EverFRESH option is operating, the process of inducing ripening by introducing ethylene should not be performed. It is required that the calibration procedure only be performed during pre-trip or when the container has been fully vented.
(Figure 2.1). The air compressor for EverFRESH is located below the condenser behind a splash guard. A manually operated venting system is located in the upper left access panel. The panel may be removed to allow entry into the evaporator section where the atmosphere sensors, control valves, water separator and air filters are located.
Other than the air compressor, all of the components of the EverFRESH option are mounted in the evaporator 2.2) in addition to the standard refrigeration unit components. section (Figure Figure 2.2 Refrigeration Unit - Evaporator Section (Upper Panel Removed) EverFRESH components located in evaporator section 2.3) include the water separator, particulate filters, Water Drain Valve (WDV), Nitrogen...

The compressed air then passes through the second particulate filter. This filter drains any remaining moisture from the system through the EverFRESH Air Valve (EA) solenoid. This will open after the WDV operates for draining moisture and when fresh air is required in the system. The EA maintains the desired oxygen levels inside the cargo space.
The nitrogen sampling orifice regulates the flow of nitrogen to the EverFRESH Nitrogen Valve (EN). The controller will open EN to allow the gas to flow into the sensor package for testing at the O sensor. Elevated amounts of oxygen indicate the nitrogen membrane may be clogged. EN is only energized during Pre-trip test P20- 5 N2 Check.
3.4 Pre-Trip Inspection An EverFRESH Pre-Trip Inspection (PTI) is required to run prior to cargo being loaded in order to test operation of mechanical components and calibrate the sensors. EverFRESH efficiency is directly related to box integrity, so a PTI must only be performed with a well vented container box.

Then re-run the Pre-trip “AutCA” test under the PRE-TRIP key menu. P20-5 EverFRESH Nitrogen Test will start with EAC off. EN current between 100 and 200mA. Valve (EN) Solenoid Energize EN and wait 5 seconds.
3.5 Enabling EverFRESH Operation EverFRESH is activated via function code Cd71. This code allows the user to select a specific mode of operation and the associated parameters. The modes of operation are: FrESh, OFF, and PUrgE. Within each of these modes of operation are sub menus that have selectable parameters.
When Purge mode is active, it allows the user to suspend EverFRESH operations while pre-charging gas levels in the container. All EverFRESH control actions and alarm 929 is suspended in order to purge the container to a desired gas concentration. When activated, Purge mode stays active for a period of time selected from the Purge mode sub menu.
3.5.4 Code 44 (Cd44) Cd44 allows the user to view the following EverFRESH values: CO setpoint, CO percentage, O setpoint, O percentage, O voltage and Membrane Pressure Transducer (MPT) pressure. 3.5.5 Display Cd44 Values 1. Press the CODE SELECT key on the keypad.
If during this time the manual fresh air vent is open and EverFRESH is active, an alarm will be generated. If alarm is active, the controller monitors the manual fresh air once per hour. Upon clearing the alarm, the controller goes back to monitoring at the pre-determined time.
Page 24
Action: Control O to setpoint. Controlling O may allow CO to increase, replace sensor as soon as possible. If both AL909 and AL910 are active, run the EverFRESH Air Compressor (EAC) and open the EverFRESH Air Valve (EA). Component CO Sensor Troubleshooting Check wiring (refer to schematic), and check for bad connections or wires positioned improperly.

Troubleshooting Seal container where possible (access panels, rear doors, mounting hardware, etc). AL976 Air Compressor Internal Protector Open Cause: EverFRESH Air Compressor (EAC) internal protector opens. Component EverFRESH Air Compressor (EAC) Troubleshooting Follow steps defined in AL929 EAC testing. Component ML5 Controller Troubleshooting Access function code Cd74 to perform an ML5 self-diagnostic test.

Membrane Pressure Transducer (MPT) Fault Cause: When the EverFRESH Air Compressor (EAC) is running and pressure is not between -5 psig and 200 psig or the EAC has been OFF for five minutes and pressure is not within the range of -5 psig and 5 psig.
Page 27
AL980 Fresh Air Valve (EA) Fault Cause: When the system energizes the EverFRESH Air Valve (EA) solenoid and membrane pressure does not drop 40 psi, the alarm is triggered. The alarm triggers OFF when membrane pressure transducer (MPT) pressure drop is more than 40 psi when EA is opened.
