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 10
CAUTION Do not run the Calibration tests under loaded conditions. While the EverFRESH option is operating, the process of inducing ripening by introducing eth- ylene should not be performed. It is required that the calibration procedure only be performed during Pre-Trip or when the con- tainer 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...
Optional CO2 Injection System There is an optional CO2 injection kit that can be added to the system that allows CO2 to be actively injected into the cargo space during transport. In this configuration, a CO bottle is used with a regulator to maintain an input pressure of 50 psig, not to exceed 100 psig.

O2 levels from dropping below the lower setpoint. A CO2 sensor provides CO2 levels to the controller to allow the control algorithm to activate the required EverFRESH components. For low respiring cargoes requiring high CO2 setpoints, an optional CO2 Injection system can be used to maintain CO2 levels.
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 O2 Sensor. Elevated amounts of oxygen indicate the Nitrogen Membrane may be clogged. The EN is only energized during Pre-trip test P20-5 N2 Check.
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. 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 Valve (EN) Solenoid Test Test Sequence: Test will start with EAC off. Energize EN and wait 5 seconds. Energize EAC. Test will run up to an additional 300 seconds or until N2 reaches acceptable limit. Then the EAC and EN will be de-energized.
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. Use the Arrow keys to toggle between “On” and “OFF” and press ENTER to confirm the selection. 3.5.5 Code 44 (Cd44) Cd44 allows the user to view the following EverFRESH values: CO2 setpoint, CO2 percentage, O2 setpoint, O2 percentage, O2 voltage and Membrane Pressure Transducer (MPT) pressure. 3.5.6 Display Cd44 Values 1.
Container Venting Procedure WARNING Potential hazardous atmosphere and low oxygen levels may exist inside the container. Venti- late before entering. Stay away from doors and access panels while venting. 1. Set the Start-Stop (ST) switch to the “I” position to turn the unit On. 2.
Manual Fresh Air Vent Open Cause: For units equipped with EverFRESH and a Vent Position Sensor (VPS), the controller will monitor the manual fresh air opening at a pre-determined time. If during this time the manual fresh air vent is open and EverFRESH is active, an alarm will be generated.
Page 26
Cause: Triggered anytime the CO2 sensor reading is outside of the normal operation range, after an initial signal was detected. Action: EverFRESH Air Compressor (EAC) 100% duty cycle and open the EverFRESH Air Valve (EA). Will prevent low O2 and cargo loss. If both AL909 and AL910 are active, run the EAC and open the EA.
Page 27
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.
Page 28
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 29
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.

5.2) 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. Figure 5.2 EverFRESH Air Valve (EA) T-374 5–20...
Removing the EverFRESH Air Valve NOTE 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) (Figure 5.2). This component can 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.

5.4) consists of an air filter, O2 sensor and CO2 sensor. The O2 sensor monitors O2 levels and allows the system to prevent O2 levels from dropping below the lower setpoint. A CO2 sensor provides CO2 levels to the controller to allow the control algorithm to activate the required EverFRESH components. Figure 5.4 Sensor Assembly...
