2 Description

This generator will produce a constant stream of ultra high purity hydrogen at a predetermined flow rate and pressure when connected to a
suitable power supply and fed with a suitable quality of deionised water. It is suitable for use in laboratories and light industrial environments and
is non-hazardous for transportation purposes.
In order to guarantee the optimum efficiency of the PEM cell, this generator must be installed and running within three months of dispatch
from Parker Hannifin. Failure to do this may invalidate the warranty.
If the generator has been stored for a period of 90 days or more, it will automatically perform a 240 minute (4 hours) initialisation sequence on
power up. This sequence, which cannot be aborted, is necessary to guarantee the correct hydration of the cell and operation of the micro-
dryer.
