6.2.1

Box Checkout / Leak Test

When using the EverFRESH system, the box must conform to leak rates in order to maintain control of the O2 and
CO2 setpoints. The minimal box requirement is a pressure decay of 2 inch WG (50mm) to 1 inch WG (25mm) of
four minutes or more for a 40 foot container. It is recommended that it be checked prior to the voyage.
To perform this check some units may be equipped with two pressure connection ports on the front of the unit. One
of the ports is connected to a pressurized air supply and the other is connected to a Magnehelic pressure gauge.
The pressure gauge monitors the container leakage rate. Refer to
