The operation of EMP-14W will be turned to eco mode by pressing "eco" button in the
operation panel. EMP-14W is operated as follows in eco mode.
When EMP-14W does not receive any requests of LN
transfer, it operates the nitrogen gas generator in a cycle of suspending for 22 hours and
running for two hours.
When the signal to request automatic transfer is input during eco mode, EMP-14W will
start automatic transfer to the target device six minutes later than signal input.
Manual dispense is not available during eco mode. To dispense manually, reset the eco
mode and wait for 6 minutes until the nitrogen gas generator resumes operation.
When the liquid nitrogen level of EMP-14W goes down to 30L (75%) or less, it resumes
LN
production automatically. Ten minutes later from the time liquid nitrogen level
2
reaches to 40L (100%), EMP-14W returns to eco mode.
When resumed after long-term suspension or newly purchased, do not turn to "eco"
mode as it may result in failure.
Set to eco mode after operating continuously for 2 weeks to 1 month. When the
suspended term is about 6 months, operate 2 weeks. If it has been suspended
longer, operate 1 month before setting to eco mode.
