Refilling the Dewar
The 25l Dewar holds enough LN
2
for a 1 day operation. It is recommended to keep
the pump in the Dewar until the LN
2
has been consumed. The LN
2
consumption of
the pump when not in use is less than 1l per day.
Refilling can be done in 2 different ways:
1. Lift the pump slightly and refill the Dewar, using the Dewar Refilling System.
2. Take out the pump from the Dewar. The cold pump should always be kept in an
upright position to avoid entrance of water and humid air into the valves. Use the
yellow protective cap immediately to close the lower end of the pump. Before
inserting the pump again, dry pump and take off yellow protective cap.
For ease of operation, one can use a second Dewar and place the pump
immediately into the new, full Dewar.
Taking out the pump from the Dewar if the pump is not in use for a longer
time:
The cold pump should always be kept in an upright position to avoid entrance of
water and humid air into the valves. Use the yellow protective cap and the storing
bracket that is provided with the pump.
Before removing the pump from the Dewar, switch off pump and wait for a few
minutes. The LN
2
hose must be flexible enough to be moved.
