mode
The operation of EMP-14A will be turned to eco mode by pressing “eco” button on the
operation panel. When in eco mode, EMP-14A is operated as follows.
When EMP-14A does not receive any requests for LN2 production and transfer,
EMP-0114A will be operated with the cycle of 22 hours’ suspension and 2 hours
production.
When the signal to request automatic transfer is input while in eco mode, EMP-14A will
start the transfer in six minutes.
Manual dispense is not available during eco mode. To dispense manually, reset eco
mode and wait for 6 minutes until the nitrogen gas generator resumes operation.
When the liquid nitrogen level is lowered to 30L (75%) or less, EMP-14A resumes
production automatically. It returns to eco-mode ten minutes later than the liquid
nitrogen level reaches 40L (100%).
CAUTION
When resumed after long-term suspension or newly purchased, do not turn to
“eco” mode immediately after starting operation. It may result in failure.
Set to eco mode after operating continuously for 2 weeks to 1 month. Operate
for two weeks when it is suspended for about 6 months. If the suspended term
is longer, operate for 1 month.
